LORELEI sings praises of neoadjuvant taselisib/letrozole in ER+/HER2– breast cancer
MADRID – Adding the investigational PI3K inhibitor taselisib to letrozole (Femara) significantly improved overall response rates, compared with neoadjuvant letrozole alone, in postmenopausal women with early estrogen receptor–positive, human epidermal growth factor receptor 2–negative (ER+/HER2–) breast cancer, results of the LORELEI trial show.
In this phase 2 trial, the overall response rate (ORR), the primary endpoint, was 50% for 166 patients assigned to letrozole plus taselisib, compared with 39.3% for 168 patients assigned to letrozole plus placebo, reported Cristina Saura, MD, of Vall d’Hebron University Hospital in Barcelona.
Although the pathologic complete rate (pCR) was low in each study arm, this was not unexpected, due to the short course (4 months) of endocrine-based therapy, she said.
Taselisib is a selective inhibitor of phosphatidylinositol 3-kinase (PI3K), with enhanced activity against the mutation isoform of the protein, labeled p110a. The PI3K alpha isoform, Taselisib degrades p110a by a mechanism of action that is different from other PI3K inhibitors, Dr. Saura said.
As monotherapy and in combination with endocrine therapy agents in phase 1 trials, taselisib elicited partial responses in patients with PIK3CA-mutated metastatic breast cancer, she noted.
In LORELEI, 334 postmenopausal women with previously untreated ER+/HER2– stage I-III operable breast cancer with tumors of 2 cm or greater on MRI were enrolled. The patients were stratified by tumor size and nodal status and then randomly assigned to letrozole 2.5 mg daily plus taselisib 4 mg taken in 2 mg doses twice daily for 5 days each week for 16 weeks, or letrozole plus placebo. Patients then went on to surgery, were followed for safety for 30 days, and then had adjuvant therapy consisting of endocrine therapy and/or chemotherapy and/or radiation therapy.
As noted, the ORR for patients assigned to the combination was 50%, consisting of 4.8% CR, and 45.2% partial responses (PR). Additionally, 40.4% of patients assigned to the taselisib arm had stable disease. The corresponding response rates for patients assigned to the letrozole/placebo arm were 1.8%, 37.5%, and 51.2%.
The odds ratio favoring the combination was 1.55 (P = .049).
For the subset of patients with PIK3CA-mutated tumors, the ORR was 56.2% for 73 patients in the taselisib arm, vs. 38% for 79 patients in the placebo arm (OR, 2.03; P = .033).
The pCRs in the overall population were 1.8% with taselisib vs. 0.6% with placebo. The corresponding pCRs in the PIK3CA-mutated population were 1.4% and 0%. None of the differences were statistically significant.
In all, 11.4% of patients assigned to taselisib required dose reductions, and 10.8% had to discontinue the drug.
The incidence of adverse events of any grade was 91% with letrozole/taselisib, and 83.2% with letrozole placebo.
Taselisib was associated with higher rates of gastrointestinal side effects, skin and subcutaneous disorders, metabolic and nutritional side effects and respiratory, thoracic, and mediastinal disorders. Patients in the taselisib arm had a lower incidence of musculoskeletal/connective tissue problems, vascular disorders, and psychiatric complaints.
The toxicities were generally manageable and consistent with that of other PI3K inhibitors, Dr. Saura said.
She said that although taselisib is more selective than other PI3K inhibitors and has a somewhat lower incidence of GI toxicities, “it’s still difficult to manage as a drug in the clinic, but I think if we can tell a patient there is a selection criterion which is a PIK3CA mutation, then patients are more willing and we as therapists are more willing to give those drugs.”
LORELEI provides the first clinical proof of efficacy of a specific PI3K inhibitor in early breast cancer, and “results of confirmatory phase 3 trials in metastatic breast cancer are eagerly awaited,” Dr. Harbeck added.
The study was supported by Genentech/F. Hoffman–La Roche. Dr. Saura disclosed consulting fees and institutional funding from Roche. Dr. Harbeck reported no disclosures relevant to the study.

Surgeons strongly influenced chances of contralateral prophylactic mastectomy
Surgeons, not clinical factors, accounted for 20% of variation in rates of contralateral prophylactic mastectomy (CPM), according to the results of a large survey study.
Only 4% of patients elected CPM when their surgeons were among those who least favored it overall and most preferred breast-conserving treatment, according to Steven J. Katz, MD, MPH, of the University of Michigan, Ann Arbor, and his associates. But 34% of patients chose CPM when their surgeons least favored BCT and were most willing to perform CPM, the researchers found. “Attending surgeons exert strong influence on the likelihood of receipt of CPM after diagnosis of breast cancer,” highlighting “the need to help surgeons address this growing clinical conundrum in the examination room,” they wrote (JAMA Surg. 2017 Sep 13. doi: 10.1001/jamasurg.2017.3415).
Rates of CPM have risen markedly in the United States although it has not been shown to confer a survival advantage for average-risk women. To examine how surgeons themselves affected rates of CPM, the investigators sent surveys to 7,810 women treated for stage 0 to II breast cancer from 2013 to 2015 and included in the Surveillance, Epidemiology, and End Results (SEER) registries of Georgia and Los Angeles County. (Among the 7,810 women, 507 were ineligible.) The researchers also surveyed 488 attending surgeons of these patients.
Response rates were high – 70% among patients (5,080 of 7,303) and 77% (377 of 488) among surgeons, the investigators reported. The average age of the patients was 62 years; 28% had an elevated risk of second primary cancer, and 16% underwent CPM. Patients whose surgeons’ rates of CPM exceeded the mean by at least one standard deviation had nearly threefold greater odds of undergoing CPM themselves (odds ratio, 2.8; 95% confidence interval, 2.1-3.4) regardless of age, date of diagnosis, BRCA mutation status, or risk of second primary cancer.
“One quarter of the surgeon influence was explained by attending attitudes about initial recommendations for surgery and responses to patient requests for CPM,” the researchers wrote. Additional predictors of CPM included elevated risk of second primary breast cancer, BRCA mutation, and younger age.
“We observed a range of reasons why a surgeon would be willing to perform CPM if asked: give peace of mind, yield better cosmetic outcomes, avoid conflict with patient, reduce need for surveillance, improve long-term quality of life, reduce recurrence of invasive disease, avoid losing patient to another surgeon, or improve survival (in order of endorsement),” the researchers wrote. “Our findings reinforce the need to address better ways to communicate with patients with regard to their beliefs about the benefits of more extensive surgery and their reactions to the management plan including surgeon training and deployment of decision aids.”
The National Cancer Institute provided funding. The researchers reported having no conflicts of interest.
Patients who are provided education tools regarding the decision between [breast conserving therapy] and mastectomy are more likely to opt for BCT. However, this discussion is arduous and time consuming. We offer decision-making autonomy to patients, but, in creating that autonomy, we have resigned to overtreatment, motivated by the desire to avoid creating conflict in our relationship with the patient.
How do we overcome this hurdle? Consensus statements reinforce that contralateral prophylactic mastectomy should be discouraged in average-risk patients, but it is time to move beyond consensus statements and create communication tools that guide the surgeon and patient through a stepwise informed discussion. We are participating in a multi-institutional randomized trial to develop such an aid, and we believe this will effect real change in the way surgeons counsel patients. The goal is to standardize the methods and information patients receive to ensure that their decisions are based on facts, not fear.

Ten-year outcomes support skipping axillary lymph node dissection with positive sentinel nodes
A follow-up to a study showing the noninferiority of sentinel lymph node dissection to axillary lymph node dissection for breast cancer in overall and disease-free survival at a median of 6.3 years found similar noninferiority in overall survival at 10 years.
Axillary lymph node dissection has a risk of complications including lymphedema, numbness, axillary web syndrome, and decreased upper-extremity range of motion. The American College of Surgeons Oncology Group Z0011 trial sought to determine if the procedure could be avoided without inferior survival outcomes.
Criticism of the study focused on the potential for later recurrence, particularly in patients with hormone receptor–positive breast cancer. All enrolled patients had one or two sentinel nodes with metastases. At randomization, 436 received sentinel lymph node dissection alone, and 420 received the additional axillary lymph node dissection. The patients were assessed every 6 months for the first 3 years, then annually.
After a median of 9.3 years, 110 of the patients had died of any cause – 51 in the sentinel lymph node dissection group and 59 in the axillary lymph node dissection group – a 10-year overall survival rate of 86.3% and 83.6%, respectively. This met the study’s primary endpoint of showing noninferior overall survival without the riskier procedure. In the study’s secondary endpoint, disease-free survival, there was not a significant difference either (80.2% vs. 78.2%).
“Axillary dissections are associated with considerable morbidity, and the results of this trial demonstrated that this morbidity can be avoided without decreasing cancer control. … These findings do not support routine use of axillary lymph node dissection in this patient population based on 10-year outcomes,” wrote Armando E. Guiliano, MD, of Cedars-Sinai Medical, Los Angeles and his coauthors (JAMA. 2017;318[10]:918-26. doi: 10.1001/jama.2017.11470).

Assessing a multidisciplinary survivorship program in a group of predominantly Hispanic women with breast cancer
Breast cancer survivors comprise the most prevalent cancer survivor population in the United States.1 The number of breast cancer survivors is increasing because of early detection and diagnosis, and advances in treatment have resulted in increased life expectancy. Therefore, greater attention is needed to improve the long-term quality of life of these survivors and to help them re-adjust to normal life. For many women, although the medical treatment may have been completed, the recovery process may have not.2 The prevalence of long-term mental and physical illness is significant among many breast cancer survivors. Long-term mental consequences may include memory problems, anxiety, depression, and fear of recurrence3, and long-term physical consequences may include pain, fatigue, and lymphedema, among others.4
El Paso, Texas, is the fourth most populous city in Texas and has a Hispanic majority. This provides an opportunity to conduct clinical research targeting participants of Hispanic descent. Several studies have noted the influence of race/ethnicity on the psychosocial function of breast cancer survivors.5,6 We have previously reported that Hispanic breast cancer survivors might experience decreased mental and physical health-related quality of life (QoL) which limit their normal social functioning.6Other studies have similarly reported poor outcomes of breast cancer survivors and higher rates of fatigue and depression among Hispanic patients.7 However, there is a paucity of research addressing specific interventions needed to improve these outcomes and provide better QoL for breast cancer survivors.8,9 In addition, a few survivorship care interventions have focused on minorities. We sought to assess whether a multidisciplinary cancer survivorship program in a primarily Hispanic populated area would lead to improved QoL and reduce anxiety and depressive symptoms among breast cancer survivors.
Methods
After obtaining Institutional Review Board approval, we recruited consecutive patients who were treated at our institution during October 2013-October 2014 and obtained informed consent from them. The participants were within the first 5 years after diagnosis with stages I-III breast cancer and had completed surgery, chemotherapy, and/or radiation therapy. We sought to determine whether breast cancer survivors would benefit from this intervention as determined by improvement of performance at 12 months compared with baseline based on the following self-reported validated questionnaires: Patient Health Questionnaire-9 (PHQ-9) for depression; General Anxiety Disorder-7 (GAD-7); and Short-Form Health Survey-36 (SF-36, version 2) for patient quality of life. The participants were enrolled in a comprehensive survivorship program staffed by an oncologist, an oncology nurse practitioner, a nutritionist, and a certified clinical psychologist who had trained in mindfulness-based stress reduction (MBSR).
Interventions
The participants received a one-on-one individual psychological consultation visit every 3 months for 20-45 minutes during which the psychologist addressed each patient’s emotional and psychological issues in depth, discussed relaxation techniques, and provided psychosocial counselling. In addition, all participants were asked to attend an 8-week-course (in Spanish or English) using MBSR, an interventional program in which participants receive training to promote reduction of stress by self-regulating mindfulness practice.3,10 Our institution’s MBSR program consists of a weekly 2-hour class for 8 sessions or more. The program is provided 3 times a year, in English and Spanish. It includes the following components:
- Learning various mindfulness meditation techniques (eg, body scans, awareness of breathing, sitting/walking meditations);
- Practicing the mindfulness techniques in class; and
- Practicing techniques at home through audiorecordings of mindfulness meditation exercises and daily diary writing.
Participants were provided with a workbook on MBSR in their preferred language.11 In addition to the psychological component, they were also provided with oncologic evaluations by an oncology nurse practitioner. The nurse practitioner met with participants every 3 months and provided each one with a personalized summary of all the treatments received and routine oncology follow-up care in consultation with the patients’ regular oncologists. This care also addresses the long-term sequelae of treatment, including arthritis and osteoporosis, referrals to receive screening for other cancers (eg, cervical and colon cancer), and genetic counselling as appropriate. In addition, a nutritionist provided general dietary advice in individual and group sessions every 3 months.
The self-administered questionnaires, PHQ-9, GAD-7, and SF-36, were completed at baseline, and every 3 months for 12 months. The scores were reviewed by the psychologist and the oncologist. The PHQ-9 was used to initially screen survivors for depression and monitor their improvement after the intervention. The PHQ-9 is a reliable and validated self-administered depression module.12 The PQH-9 exclusively focuses on the 9 diagnostic criteria for DSM-IV depression disorder and it can be used as a useful measure for monitoring outcomes of depression therapy. A score of 5-14 suggests mild-moderate depression, and a score of >15 suggests severe depression
The survivors were screened for anxiety using the GAD-7, a brief 7-item self-report scale to identify probable cases of anxiety disorder that has been shown to be an efficient tool for screening and assessing the severity of anxiety.13 For GAD-7, a score of 5 or higher is suggestive of anxiety. Scores of 5, 10, and 15 represent cut-off points for mild, moderate, and severe anxiety, respectively.
Survivor QoL was evaluated using the SF-36 questionnaire, a multipurpose survey containing 36 questions. It ranges from 0-100 and a score that is <50.0 is considered low. The lower the score, the worse the mental or physical function.14 The SF-36 yields a patient profile of 8 health domains – vitality, physical functioning, bodily pain, general health perceptions, physical, emotional, and social role functioning; and mental health.15,16 A score of 50.0 on either the Physical Component Summary (PCS – vitality, physical functioning, bodily pain, general health perceptions, physical role functioning) or Mental Component Summary (MCS – emotional and social role functioning, and mental health) is consistent with the US norm.
Statistical analysis
In this study, the primary objective was to use the MBSR survivorship program to improve the survivors’ outcomes at 12 months compared with baseline using the following measures: PHQ-9 for depression, GAD-7 for anxiety, and SF-36 for QoL using the PCS and MCS. Quantitative data were described using the mean and standard deviation, and categorical data were described using frequency and percentage. The outcome measures were compared between patients who completed 12-month follow-up and those who did not, using unpaired t test. The change in outcome measures at 12 months from baseline was evaluated using paired t test. The effect of intervention was summarized using relative percentage change. The “dose” of the intervention was categorized the number of MBSR sessions – ≤4 sessions, 5-7 sessions, or ≤8 sessions. The change in outcome measures were compared among three groups using 1-way analysis of variance (ANOVA) followed by post hoc multiple comparison using the Bonferroni adjustment. In addition, the effect of intervention on each outcome was evaluated by important baseline characteristics of patients. In each subgroup, the changes were compared with baseline measures using the paired t test, whereas changes in outcome between groups were compared using the unpaired t test. Statistical analyses were conducted using SAS 9.3. P-values less than 5% were considered to be significant.
Results
A total of 94 survivors of breast cancer were included in this study and 60 (63.8%) completed the 12 months of follow-up. The average age of the participants was 54.4 years (SD, 8.7), and 90.4% were Hispanic (Table 1). Tumor characteristics were as follows: invasive ductal carcinoma (84.04%), estrogen receptor–positive (ER-, 71.28%), progesterone receptor–positive (PR-, 58.51%), and HER2-neu–positive (20%). In regard to therapy received, 48% of the participants had received anthracycline- and taxane-based adjuvant chemotherapy and 23%, nonanthracycline-based chemotherapy; 71% had received anti-estrogen (hormonal) therapy and 80%, radiation therapy. In regard to surgery, half of the participants had a lumpectomy, and half, a mastectomy. The trends in the outcome measures over the follow-up period are show in the Figure 1.
The effect of survivorship program intervention on SF-36 (PCS and MCS), anxiety (GAD-7), and (PHQ-9) at 12 months are shown in Table 2, which also includes the 12-month effects on the body-mass index (BMI). The P-values correspond to the comparison of mean change in scores between baseline and 12-month follow-up. Significant improvement from baseline was observed for PHQ-9 (P = .0031) and GAD-7 (P = .0027). There was a significant trend toward improvement (14%) relative to baseline in the SF-36 MCS at 12 months (P = .097). Although the SF-36 PCS improved numerically, it did not reach to a statistical significance level (P = .896). The BMI at 12 months was found to be statistically significantly increased compared with baseline (P = .0007).
The effect of the number of MBSR sessions attended on the outcome measures is summarized in Table 3. There were significant improvements in the 12-month MCS scores for patients who completed 5-7 sessions of MBSR or ≥8 sessions, compared with patients who completed ≤4 sessions of MBSR. There was an improvement observed in PCS scores only among patients who received at least 8 sessions of MBSR. There was a marked improvement observed in GAD-7 and PHQ-9 among patients who received ≥8 sessions. There was no statistically significant change in the GAD-7 or PHQ-9 scores between patients who received ≤4 sessions and 5-7 sessions. No significant association was obtained between number of MBSR sessions attended and BMI.
The effect of survivorship program intervention on all outcomes according to important baseline cofactors is shown in Table 4. As such, there were no significant differences in changes in the outcome measures after intervention according to any considered baseline characteristics. However, the effect of survivorship program intervention was more pronounced in patients who were ≥3 years away from their initial diagnosis and who had attended a minimum of 80% of the 3-monthly visits and received a minimum of 8 MBSR sessions.
The mean baseline PCS and MCS scores of the SF-36 were 43.7 and 45.8, respectively, indicating that the participants’ scores were significantly less than half the standard deviation below the US norm (50.0; SD, 10). The SF-36 health-related QoL categories showed that, on an average, scores improved by more than 4 units for emotional and physical role functions, vitality, and mental health compared with baseline. In addition, scores improved by about 2 units for general health and social functioning compared with baseline data. In all, 65% of survivors had difficulty preforming work at baseline, but that dropped to 55% after enrollment in the program; and 60% had originally reduced the amount of time spent on work, but that increased to 50% after the intervention. Also of note is that 70% of survivors reported accomplishing less than they would like to have (role physical) before the intervention, but that was reduced to 57% after the intervention. Similarly, 77% of survivors felt worn out at baseline, compared with 65% at the 12-month follow-up; and 88% felt tired at baseline, but that percentage was reduced to 68% after the intervention. Before the intervention, 60% of the participants reported that they had been very nervous, and 45% said they had been so down in the dumps that nothing could cheer them up, but those percentages were reduced to 43% and 32%, respectively, after intervention. Before intervention, 63% of the women said they felt depressed and that was reduced to 50% after the intervention.
Discussion
In this study, we showed that a group of predominately Hispanic breast cancer survivors benefited from participating in a multidisciplinary cancer survivorship program that emphasized in-depth psychological care and MBSR. They also benefited from an education effort that included providing survivors with personalized summaries of their treatment and oncology survivorship care, addressing potential long-term side effects of treatment, referral for genetic counselling and screening for other cancers as appropriate, as well dietary advice. We found significant improvement compared with baseline in both mental and physical determinants of the patient-reported outcomes, including anxiety (GAD-7), depression (PHQ-9), and HR-QoL (PCS) and (MCS). Survivors demonstrated significant improvement on the MCS and PHQ-9 if they attended 5 or more sessions of the 8-week MBSR course, and attending 8 sessions was associated with significant improvement in GAD-7 and PCS. This might suggest that survivors who are more motivated do benefit the most from such program.
To our knowledge, this study is the first to address the benefit of the MBSR intervention in Hispanic breast cancer survivors. In a randomized controlled trial that included breast cancer survivors with stages 0-III breast cancer who completed surgery, adjunctive radiation, and/or chemotherapy, MBSR was shown to reduce the symptoms of depression and anxiety and increase energy and physical functioning compared with participants who received “usual care”.3 Furthermore, Bower and colleagues have reported improvements in sleep, fatigue, and pro-inflammatory signaling in younger survivors of breast cancer.17 A similar standardized MBSR program was tested on Danish women who had been treated for stage I-III breast cancer18 and the results showed reduced levels of anxiety and depression at the 12-month follow-up. A similar study by Hoffman and colleagues19 reported improved mood, breast- and endocrine-related quality of life, and well-being with MBSR compared with standard care in women with stage 0-III breast cancer.
Several theories have been suggested to explain how MBSR reduces symptoms of depression, anxiety, and fear of recurrence in breast cancer survivors, one of which is that it provides supportive interaction between group members to practice meditation and apply mindfulness in daily situations.3 In addition, evidence is beginning to emerge that stress-reducing interventions such as MBSR may improve telomere length (TL) and telomerase activity (TA), the markers for cellular aging, psychological stress, and disease risk.20-24 Lengacher and colleagues conducted a randomized controlled study to investigate the effects of MBSR on TL and TA in women with breast cancer, and suggested that MBSR increases telomere length and telomerase activity.25 The 142 patients with stages 0-III breast cancer had completed adjuvant treatment with radiation and/or chemotherapy at least 2 weeks before enrollment and within 2 years of completion of treatment with lumpectomy and/or mastectomy. They were randomly assigned to either a 6-week MBSR for breast cancer program or usual care.25 Assessments of TA and TL were obtained along with psychological measurements at baseline, 6 weeks, and 12 weeks after the patients had completed the MBSR program. The mean age of the participants was 55.3 years; 72% were non-Hispanic white; 78% had stage I or II cancer; and 36% received both chemotherapy and radiation. In analyses adjusted for baseline TA and psychological status, TA increased steadily by about 17% over 12 weeks in the MBSR group, compared with about 3% (P < .01) in the control group. No difference was observed for TL (P = .92). The authors concluded that the data provide preliminary evidence that MBSR increases TA in peripheral blood mononuclear cells from breast cancer patients and have implications for understanding how MBSR may extend cell longevity at the cellular level.
In another study among healthy volunteers who were randomly assigned to a 3-month meditation retreat or a control group, the 30 participants in the meditation group had higher TA compared with controls.20 In a nonrandomized study among prostate cancer patients, TA increased and psychological stress decreased following a stress-reducing, lifestyle-modification program.21 The results of another intervention study among overweight women showed improvement in distress, eating behavior, and metabolic health in women participating in a MBSR program, all of which correlated with increases in TA.22 Most recently, researchers explored the impact on TA of a Kirtan Kriya yogic meditation intervention compared with exposure to relaxing music in 39 dementia family caregivers. The yogic-meditation intervention group had a 43% increase in TA after the 8-week intervention period compared with 3.7% the music group (P < .05).23 Finally, among 22 patients with cervical cancer who were randomized to a psychosocial telephone counseling intervention,24 investigators found a significant association between increased TL and changes in psychological distress.20 Findings from other studies have assessed interventions to improve outcome of breast cancer survivors, such as the Taking CHARGE self-management intervention that is designed to facilitate the transition to survivorship after breast cancer treatment.8 Another intervention using home-based physical activity was shown in a randomized controlled trial to improve self-reported physical activity, body-mass index, and health-related QoL.9 Findings from another study suggested that a combined exercise and psychological counselling program might improve QoL more than a single entity intervention.26 As noted previously, these studies did not focus on minority breast cancer survivors’ population, and it is not clear if they are generalizable to Hispanics.
In addition to the MBSR component, our program has also included one-on-one psychological assessment for long-term treatment complications and provided participants with appropriate care and follow-up plans, adding the benefits of self-awareness and self-attention for the survivors, which can effectively reduce the fear of recurrence.3 Furthermore, we included dietary consults based on general cancer survivor guidelines recommending a high fruit and vegetable diet that is low in fat and sugar.27 Healthier dietary lifestyle has been reported to improve breast cancer prognosis, metabolic disease, and cardiovascular outcomes among Hispanic breast cancer survivors.28
Our study has some limitations, including a relatively small sample size. It did not include an exercise program, which would have been helpful in addressing the issue of overweight and obesity we encountered in the most of the Hispanic breast cancer survivors (baseline average BMI, 31.32 kg/m2; obesity range, >30 kg/m2). Because of the small sample size and nonrandomized design of the study, it is hard to evaluate the confounding effect of time on intervention effect. However, a subgroup analysis by MBSR number of sessions showed that the survivors who completed the full course of MBSR sessions (8 sessions) achieved superior benefit, compared with those who did not complete the full course, which indicates that the intervention did weigh in regardless of time. Despite these limitations, the participants in this interventional program showed improved outcomes, including less anxiety and depression and improved MCS score of the SF-36. A larger and longer follow-up prospective, randomized study is needed to validate the findings of this study. Implementing cancer survivorship as an integral component of cancer care during and after treatment is essential to improve the quality of life of cancer survivors and empower them in their transition from cancer treatment to survivorship.

Breast cancer survivors comprise the most prevalent cancer survivor population in the United States.1 The number of breast cancer survivors is increasing because of early detection and diagnosis, and advances in treatment have resulted in increased life expectancy. Therefore, greater attention is needed to improve the long-term quality of life of these survivors and to help them re-adjust to normal life. For many women, although the medical treatment may have been completed, the recovery process may have not.2 The prevalence of long-term mental and physical illness is significant among many breast cancer survivors. Long-term mental consequences may include memory problems, anxiety, depression, and fear of recurrence3, and long-term physical consequences may include pain, fatigue, and lymphedema, among others.4
El Paso, Texas, is the fourth most populous city in Texas and has a Hispanic majority. This provides an opportunity to conduct clinical research targeting participants of Hispanic descent.

We sought to determine whether breast cancer survivors would benefit from this intervention as determined by improvement of performance at 12 months compared with baseline based on the following self-reported validated questionnaires: Patient Health Questionnaire-9 (PHQ-9) for depression; General Anxiety Disorder-7 (GAD-7); and Short-Form Health Survey-36 (SF-36, version 2) for patient quality of life.

Although the SF-36 PCS improved numerically, it did not reach to a statistical significance level (P = .896). The BMI at 12 months was found to be statistically significantly increased compared with baseline (P = .0007).
The effect of the number of MBSR sessions attended on the outcome measures is summarized in Table 3. There were significant improvements in the 12-month MCS scores for patients who completed 5-7 sessions of MBSR or ≥8 sessions, compared with patients who completed ≤4 sessions of MBSR. There was an improvement observed in PCS scores only among patients who received at least 8 sessions of MBSR. There was a marked improvement observed in GAD-7 and PHQ-9 among patients who received ≥8 sessions. There was no statistically significant change in the GAD-7 or PHQ-9 scores between patients who received ≤4 sessions and 5-7 sessions. No significant association was obtained between number of MBSR sessions attended and BMI.
The effect of survivorship program intervention on all outcomes according to important baseline cofactors is shown in Table 4. As such, there were no significant differences in changes in the outcome measures after intervention according to any considered baseline characteristics. However, the effect of survivorship program intervention was more pronounced in patients who were ≥3 years away from their initial diagnosis and who had attended a minimum of 80% of the 3-monthly visits and received a minimum of 8 MBSR sessions.
The mean baseline PCS and MCS scores of the SF-36 were 43.7 and 45.8, respectively, indicating that the participants’ scores were significantly less than half the standard deviation below the US norm (50.0; SD, 10). The SF-36 health-related QoL categories showed that, on an average, scores improved by more than 4 units for emotional and physical role functions, vitality, and mental health compared with baseline. In addition, scores improved by about 2 units for general health and social functioning compared with baseline data. In all, 65% of survivors had difficulty preforming work at baseline, but that dropped to 55% after enrollment in the program; and 60% had originally reduced the amount of time spent on work, but that increased to 50% after the intervention. Also of note is that 70% of survivors reported accomplishing less than they would like to have (role physical) before the intervention, but that was reduced to 57% after the intervention. Similarly, 77% of survivors felt worn out at baseline, compared with 65% at the 12-month follow-up; and 88% felt tired at baseline, but that percentage was reduced to 68% after the intervention. Before the intervention, 60% of the participants reported that they had been very nervous, and 45% said they had been so down in the dumps that nothing could cheer them up, but those percentages were reduced to 43% and 32%, respectively, after intervention. Before intervention, 63% of the women said they felt depressed and that was reduced to 50% after the intervention.
Discussion
In this study, we showed that a group of predominately Hispanic breast cancer survivors benefited from participating in a multidisciplinary cancer survivorship program that emphasized in-depth psychological care and MBSR. They also benefited from an education effort that included providing survivors with personalized summaries of their treatment and oncology survivorship care, addressing potential long-term side effects of treatment, referral for genetic counselling and screening for other cancers as appropriate, as well dietary advice. We found significant improvement compared with baseline in both mental and physical determinants of the patient-reported outcomes, including anxiety (GAD-7), depression (PHQ-9), and HR-QoL (PCS) and (MCS). Survivors demonstrated significant improvement on the MCS and PHQ-9 if they attended 5 or more sessions of the 8-week MBSR course, and attending 8 sessions was associated with significant improvement in GAD-7 and PCS. This might suggest that survivors who are more motivated do benefit the most from such program.
To our knowledge, this study is the first to address the benefit of the MBSR intervention in Hispanic breast cancer survivors. In a randomized controlled trial that included breast cancer survivors with stages 0-III breast cancer who completed surgery, adjunctive radiation, and/or chemotherapy, MBSR was shown to reduce the symptoms of depression and anxiety and increase energy and physical functioning compared with participants who received “usual care”.3 Furthermore, Bower and colleagues have reported improvements in sleep, fatigue, and pro-inflammatory signaling in younger survivors of breast cancer.17 A similar standardized MBSR program was tested on Danish women who had been treated for stage I-III breast cancer18 and the results showed reduced levels of anxiety and depression at the 12-month follow-up. A similar study by Hoffman and colleagues19 reported improved mood, breast- and endocrine-related quality of life, and well-being with MBSR compared with standard care in women with stage 0-III breast cancer.
Several theories have been suggested to explain how MBSR reduces symptoms of depression, anxiety, and fear of recurrence in breast cancer survivors, one of which is that it provides supportive interaction between group members to practice meditation and apply mindfulness in daily situations.3 In addition, evidence is beginning to emerge that stress-reducing interventions such as MBSR may improve telomere length (TL) and telomerase activity (TA), the markers for cellular aging, psychological stress, and disease risk.20-24 Lengacher and colleagues conducted a randomized controlled study to investigate the effects of MBSR on TL and TA in women with breast cancer, and suggested that MBSR increases telomere length and telomerase activity.25 The 142 patients with stages 0-III breast cancer had completed adjuvant treatment with radiation and/or chemotherapy at least 2 weeks before enrollment and within 2 years of completion of treatment with lumpectomy and/or mastectomy. They were randomly assigned to either a 6-week MBSR for breast cancer program or usual care.25 Assessments of TA and TL were obtained along with psychological measurements at baseline, 6 weeks, and 12 weeks after the patients had completed the MBSR program. The mean age of the participants was 55.3 years; 72% were non-Hispanic white; 78% had stage I or II cancer; and 36% received both chemotherapy and radiation. In analyses adjusted for baseline TA and psychological status, TA increased steadily by about 17% over 12 weeks in the MBSR group, compared with about 3% (P < .01) in the control group. No difference was observed for TL (P = .92). The authors concluded that the data provide preliminary evidence that MBSR increases TA in peripheral blood mononuclear cells from breast cancer patients and have implications for understanding how MBSR may extend cell longevity at the cellular level.
In another study among healthy volunteers who were randomly assigned to a 3-month meditation retreat or a control group, the 30 participants in the meditation group had higher TA compared with controls.20 In a nonrandomized study among prostate cancer patients, TA increased and psychological stress decreased following a stress-reducing, lifestyle-modification program.21 The results of another intervention study among overweight women showed improvement in distress, eating behavior, and metabolic health in women participating in a MBSR program, all of which correlated with increases in TA.22 Most recently, researchers explored the impact on TA of a Kirtan Kriya yogic meditation intervention compared with exposure to relaxing music in 39 dementia family caregivers. The yogic-meditation intervention group had a 43% increase in TA after the 8-week intervention period compared with 3.7% the music group (P < .05).23 Finally, among 22 patients with cervical cancer who were randomized to a psychosocial telephone counseling intervention,24 investigators found a significant association between increased TL and changes in psychological distress.20 Findings from other studies have assessed interventions to improve outcome of breast cancer survivors, such as the Taking CHARGE self-management intervention that is designed to facilitate the transition to survivorship after breast cancer treatment.8 Another intervention using home-based physical activity was shown in a randomized controlled trial to improve self-reported physical activity, body-mass index, and health-related QoL.9 Findings from another study suggested that a combined exercise and psychological counselling program might improve QoL more than a single entity intervention.26 As noted previously, these studies did not focus on minority breast cancer survivors’ population, and it is not clear if they are generalizable to Hispanics.
In addition to the MBSR component, our program has also included one-on-one psychological assessment for long-term treatment complications and provided participants with appropriate care and follow-up plans, adding the benefits of self-awareness and self-attention for the survivors, which can effectively reduce the fear of recurrence.3 Furthermore, we included dietary consults based on general cancer survivor guidelines recommending a high fruit and vegetable diet that is low in fat and sugar.27 Healthier dietary lifestyle has been reported to improve breast cancer prognosis, metabolic disease, and cardiovascular outcomes among Hispanic breast cancer survivors.28
Our study has some limitations, including a relatively small sample size. It did not include an exercise program, which would have been helpful in addressing the issue of overweight and obesity we encountered in the most of the Hispanic breast cancer survivors (baseline average BMI, 31.32 kg/m2; obesity range, >30 kg/m2). Because of the small sample size and nonrandomized design of the study, it is hard to evaluate the confounding effect of time on intervention effect. However, a subgroup analysis by MBSR number of sessions showed that the survivors who completed the full course of MBSR sessions (8 sessions) achieved superior benefit, compared with those who did not complete the full course, which indicates that the intervention did weigh in regardless of time. Despite these limitations, the participants in this interventional program showed improved outcomes, including less anxiety and depression and improved MCS score of the SF-36. A larger and longer follow-up prospective, randomized study is needed to validate the findings of this study. Implementing cancer survivorship as an integral component of cancer care during and after treatment is essential to improve the quality of life of cancer survivors and empower them in their transition from cancer treatment to survivorship.
Breast cancer survivors comprise the most prevalent cancer survivor population in the United States.1 The number of breast cancer survivors is increasing because of early detection and diagnosis, and advances in treatment have resulted in increased life expectancy. Therefore, greater attention is needed to improve the long-term quality of life of these survivors and to help them re-adjust to normal life. For many women, although the medical treatment may have been completed, the recovery process may have not.2 The prevalence of long-term mental and physical illness is significant among many breast cancer survivors. Long-term mental consequences may include memory problems, anxiety, depression, and fear of recurrence3, and long-term physical consequences may include pain, fatigue, and lymphedema, among others.4
El Paso, Texas, is the fourth most populous city in Texas and has a Hispanic majority. This provides an opportunity to conduct clinical research targeting participants of Hispanic descent. Several studies have noted the influence of race/ethnicity on the psychosocial function of breast cancer survivors.5,6 We have previously reported that Hispanic breast cancer survivors might experience decreased mental and physical health-related quality of life (QoL) which limit their normal social functioning.6Other studies have similarly reported poor outcomes of breast cancer survivors and higher rates of fatigue and depression among Hispanic patients.7 However, there is a paucity of research addressing specific interventions needed to improve these outcomes and provide better QoL for breast cancer survivors.8,9 In addition, a few survivorship care interventions have focused on minorities. We sought to assess whether a multidisciplinary cancer survivorship program in a primarily Hispanic populated area would lead to improved QoL and reduce anxiety and depressive symptoms among breast cancer survivors.
Methods
After obtaining Institutional Review Board approval, we recruited consecutive patients who were treated at our institution during October 2013-October 2014 and obtained informed consent from them. The participants were within the first 5 years after diagnosis with stages I-III breast cancer and had completed surgery, chemotherapy, and/or radiation therapy. We sought to determine whether breast cancer survivors would benefit from this intervention as determined by improvement of performance at 12 months compared with baseline based on the following self-reported validated questionnaires: Patient Health Questionnaire-9 (PHQ-9) for depression; General Anxiety Disorder-7 (GAD-7); and Short-Form Health Survey-36 (SF-36, version 2) for patient quality of life. The participants were enrolled in a comprehensive survivorship program staffed by an oncologist, an oncology nurse practitioner, a nutritionist, and a certified clinical psychologist who had trained in mindfulness-based stress reduction (MBSR).
Interventions
The participants received a one-on-one individual psychological consultation visit every 3 months for 20-45 minutes during which the psychologist addressed each patient’s emotional and psychological issues in depth, discussed relaxation techniques, and provided psychosocial counselling. In addition, all participants were asked to attend an 8-week-course (in Spanish or English) using MBSR, an interventional program in which participants receive training to promote reduction of stress by self-regulating mindfulness practice.3,10 Our institution’s MBSR program consists of a weekly 2-hour class for 8 sessions or more. The program is provided 3 times a year, in English and Spanish. It includes the following components:
- Learning various mindfulness meditation techniques (eg, body scans, awareness of breathing, sitting/walking meditations);
- Practicing the mindfulness techniques in class; and
- Practicing techniques at home through audiorecordings of mindfulness meditation exercises and daily diary writing.
Participants were provided with a workbook on MBSR in their preferred language.11 In addition to the psychological component, they were also provided with oncologic evaluations by an oncology nurse practitioner. The nurse practitioner met with participants every 3 months and provided each one with a personalized summary of all the treatments received and routine oncology follow-up care in consultation with the patients’ regular oncologists. This care also addresses the long-term sequelae of treatment, including arthritis and osteoporosis, referrals to receive screening for other cancers (eg, cervical and colon cancer), and genetic counselling as appropriate. In addition, a nutritionist provided general dietary advice in individual and group sessions every 3 months.
The self-administered questionnaires, PHQ-9, GAD-7, and SF-36, were completed at baseline, and every 3 months for 12 months. The scores were reviewed by the psychologist and the oncologist. The PHQ-9 was used to initially screen survivors for depression and monitor their improvement after the intervention. The PHQ-9 is a reliable and validated self-administered depression module.12 The PQH-9 exclusively focuses on the 9 diagnostic criteria for DSM-IV depression disorder and it can be used as a useful measure for monitoring outcomes of depression therapy. A score of 5-14 suggests mild-moderate depression, and a score of >15 suggests severe depression
The survivors were screened for anxiety using the GAD-7, a brief 7-item self-report scale to identify probable cases of anxiety disorder that has been shown to be an efficient tool for screening and assessing the severity of anxiety.13 For GAD-7, a score of 5 or higher is suggestive of anxiety. Scores of 5, 10, and 15 represent cut-off points for mild, moderate, and severe anxiety, respectively.
Survivor QoL was evaluated using the SF-36 questionnaire, a multipurpose survey containing 36 questions. It ranges from 0-100 and a score that is <50.0 is considered low. The lower the score, the worse the mental or physical function.14 The SF-36 yields a patient profile of 8 health domains – vitality, physical functioning, bodily pain, general health perceptions, physical, emotional, and social role functioning; and mental health.15,16 A score of 50.0 on either the Physical Component Summary (PCS – vitality, physical functioning, bodily pain, general health perceptions, physical role functioning) or Mental Component Summary (MCS – emotional and social role functioning, and mental health) is consistent with the US norm.
Statistical analysis
In this study, the primary objective was to use the MBSR survivorship program to improve the survivors’ outcomes at 12 months compared with baseline using the following measures: PHQ-9 for depression, GAD-7 for anxiety, and SF-36 for QoL using the PCS and MCS. Quantitative data were described using the mean and standard deviation, and categorical data were described using frequency and percentage. The outcome measures were compared between patients who completed 12-month follow-up and those who did not, using unpaired t test. The change in outcome measures at 12 months from baseline was evaluated using paired t test. The effect of intervention was summarized using relative percentage change. The “dose” of the intervention was categorized the number of MBSR sessions – ≤4 sessions, 5-7 sessions, or ≤8 sessions. The change in outcome measures were compared among three groups using 1-way analysis of variance (ANOVA) followed by post hoc multiple comparison using the Bonferroni adjustment. In addition, the effect of intervention on each outcome was evaluated by important baseline characteristics of patients. In each subgroup, the changes were compared with baseline measures using the paired t test, whereas changes in outcome between groups were compared using the unpaired t test. Statistical analyses were conducted using SAS 9.3. P-values less than 5% were considered to be significant.
Results
A total of 94 survivors of breast cancer were included in this study and 60 (63.8%) completed the 12 months of follow-up. The average age of the participants was 54.4 years (SD, 8.7), and 90.4% were Hispanic (Table 1). Tumor characteristics were as follows: invasive ductal carcinoma (84.04%), estrogen receptor–positive (ER-, 71.28%), progesterone receptor–positive (PR-, 58.51%), and HER2-neu–positive (20%). In regard to therapy received, 48% of the participants had received anthracycline- and taxane-based adjuvant chemotherapy and 23%, nonanthracycline-based chemotherapy; 71% had received anti-estrogen (hormonal) therapy and 80%, radiation therapy. In regard to surgery, half of the participants had a lumpectomy, and half, a mastectomy. The trends in the outcome measures over the follow-up period are show in the Figure 1.
The effect of survivorship program intervention on SF-36 (PCS and MCS), anxiety (GAD-7), and (PHQ-9) at 12 months are shown in Table 2, which also includes the 12-month effects on the body-mass index (BMI). The P-values correspond to the comparison of mean change in scores between baseline and 12-month follow-up. Significant improvement from baseline was observed for PHQ-9 (P = .0031) and GAD-7 (P = .0027). There was a significant trend toward improvement (14%) relative to baseline in the SF-36 MCS at 12 months (P = .097). Although the SF-36 PCS improved numerically, it did not reach to a statistical significance level (P = .896). The BMI at 12 months was found to be statistically significantly increased compared with baseline (P = .0007).
The effect of the number of MBSR sessions attended on the outcome measures is summarized in Table 3. There were significant improvements in the 12-month MCS scores for patients who completed 5-7 sessions of MBSR or ≥8 sessions, compared with patients who completed ≤4 sessions of MBSR. There was an improvement observed in PCS scores only among patients who received at least 8 sessions of MBSR. There was a marked improvement observed in GAD-7 and PHQ-9 among patients who received ≥8 sessions. There was no statistically significant change in the GAD-7 or PHQ-9 scores between patients who received ≤4 sessions and 5-7 sessions. No significant association was obtained between number of MBSR sessions attended and BMI.
The effect of survivorship program intervention on all outcomes according to important baseline cofactors is shown in Table 4. As such, there were no significant differences in changes in the outcome measures after intervention according to any considered baseline characteristics. However, the effect of survivorship program intervention was more pronounced in patients who were ≥3 years away from their initial diagnosis and who had attended a minimum of 80% of the 3-monthly visits and received a minimum of 8 MBSR sessions.
The mean baseline PCS and MCS scores of the SF-36 were 43.7 and 45.8, respectively, indicating that the participants’ scores were significantly less than half the standard deviation below the US norm (50.0; SD, 10). The SF-36 health-related QoL categories showed that, on an average, scores improved by more than 4 units for emotional and physical role functions, vitality, and mental health compared with baseline. In addition, scores improved by about 2 units for general health and social functioning compared with baseline data. In all, 65% of survivors had difficulty preforming work at baseline, but that dropped to 55% after enrollment in the program; and 60% had originally reduced the amount of time spent on work, but that increased to 50% after the intervention. Also of note is that 70% of survivors reported accomplishing less than they would like to have (role physical) before the intervention, but that was reduced to 57% after the intervention. Similarly, 77% of survivors felt worn out at baseline, compared with 65% at the 12-month follow-up; and 88% felt tired at baseline, but that percentage was reduced to 68% after the intervention. Before the intervention, 60% of the participants reported that they had been very nervous, and 45% said they had been so down in the dumps that nothing could cheer them up, but those percentages were reduced to 43% and 32%, respectively, after intervention. Before intervention, 63% of the women said they felt depressed and that was reduced to 50% after the intervention.

An ASCO 2017 recap: significant advances continue
As we head into vacation season and the dog days of summer, let’s reflect for a few minutes on some of the very important advances we heard about at this year’s annual meeting of the American Society of Clinical Oncology in Chicago. Nearly 40,000 individuals registered for the conference, an indication of both the interest and the excitement around the new agents and the emerging clinical trial data. Scientific sessions dedicated to the use of combination immunotherapy, the role of antibody drug conjugates, and targeting molecular aberrations with small molecules were among the most popular (p. e236).
In the setting of metastatic breast cancer, several trials produced highly significant results that will positively affect the duration and quality of life for our patients. The use of PARP inhibitors in BRCA-mutated cancers has been shown to be effective in a few areas, particularly advanced ovarian cancer. The OlympiAD study evaluated olaparib monotherapy and a physician’s choice arm (capecitabine, eribulin, or vinorelbine) in BRCA-mutated, HER2-negative metastatic breast cancer. The 2:1 design enrolled 302 patients and demonstrated a 3-month improvement in progression-free survival (PFS) for olaparib compared with the control arm (7.0 vs 4.2 months, respectively; P = .0009). The patient population for this BRCA-mutated trial was relatively young, with a median age of 45 years, and 50% of the women were hormone positive and 30%, platinum resistant.
The CDK4/6 inhibitors continue to be impressive, with the recently reported results from the MONARCH 2 trial showing encouraging PFS and overall response rate results with the addition of the CDK4/6 inhibitor abemaciclib to fulvestrant, a selective estrogen-receptor degrader. In this study, hormone-positive, HER2-negative women who had progressed on previous endocrine therapy were randomized 2:1 to abemaciclib plus fulvestrant or placebo plus fulvestrant. A total of 669 patients were accrued, and after a median follow-up of 19 months, a highly significant PFS difference of 7 months between the abemaciclib–fulvestrant and fulvestrant–only groups was observed (16.4 vs 9.3 months, respectively; P < .0000001) along with an overall response rate of 48.1 months, compared with 21.3 months. Previous findings have demonstrated monotherapy activity for abemaciclib, and the comparisons with palbociclib and ribociclib will be forthcoming, although no comparative trials are underway. These agents will be extensively assessed in a variety of settings, including adjuvantly.
The results of the much anticipated APHINITY study, which evaluated the addition of pertuzumab to trastuzumab in the adjuvant HER2-positive setting, were met with mixed reviews. Patients were included if they had node-positive invasive breast cancer or node-negative tumors of >1.0 cm. A total of 4,804 patients (37% node negative) were enrolled in the study. The intent-to-treat primary endpoint of invasive disease-free survival (DFS) was statistically positive (P = .045), although the 3-year absolute percentages for the pertuzumab–trastuzumab and trastuzumab-only groups were 94.1% and 93.2%, respectively. It should be noted that the planned statistical assumption was for a delta of 2.6% – 91.8% and 89.2%, respectively. Thus, both arms actually did better than had been planned, which was based on historical comparisons, and the node-positive and hormone-negative subgroups trended toward a greater benefit with the addition of pertuzumab. There was, and will continue to be, much debate around the cost–benefit ratio and which patients should be offered the combination. The outstanding results with the addition of pertuzumab in the neoadjuvant setting will continue to be the setting in which the greatest absolute clinical benefit will be seen. It is unusual in this era to see trials this large planned to identify a small difference, and it is likely that resource constraints will make such studies a thing of the past.
The very active hormonal therapies, abiraterone and enzalutimide, for castrate-resistant prostate cancer remain of high interest in the area of clinical trials. The LATITUDE study evaluated a straightforward design that compared abiraterone with placebo in patients who were newly diagnosed with high-risk, metastatic hormone-naïve prostate cancer. Patients in both arms received androgen-deprivation therapy and high risk was defined by having 2 of 3 criteria: a Gleason score of ≥8; 3 or more bone lesions; or visceral disease. Of note is that 1,199 patients were enrolled before publication of the CHAARTED or STAMPEDE results, which established docetaxel as a standard for these patients. The median age in the LATITUDE trial was 68 years, with 17% of patients having visceral disease and 48% having nodal disease, making it a similar patient population to those in the docetaxel studies. The results favoring abiraterone were strikingly positive, with a 38% reduction in the risk of death (P < .0001) and a 53% reduction in the risk of radiographic progression or death (P < .0001). The regimen was well tolerated overall, and it is clear that this option will be widely considered by physicians and their patients.
Two studies addressing the importance of managing symptoms and improving outcomes were also part of the plenary session. The IDEA Collaboration conducted a prospective pooled analysis of 6 phase 3 studies that assessed 3 and 6 months of oxaliplatin-based regimens for stage 3 colon cancer. FOLFOX and CAPOX given to 12,834 patients in 6 studies from the United States, European Union, Canada, Australia, New Zealand, and Japan were evaluated for DFS, treatment compliance, and adverse events. As would be anticipated, fewer side effects, particularly neurotoxicity, and greater compliance were observed in the 3-month group. Although DFS noninferiority for 3 months of therapy was not established statistically, the overall data led the investigators to issue a consensus statement advocating for a risk-based approach in deciding the duration of therapy and recommending 3 months of therapy for patients with stage 3, T1-3N1 disease, and consideration of 6 months therapy for T4 and/ or N2 disease. The investigators also acknowledged the leader and creator of IDEA, the late Daniel Sargent, PhD, of the Mayo Clinic, who passed away far too young after a brief illness last fall (1970-2016).
The second symptom-based study was performed at Memorial Sloan Kettering Cancer Center (MSKCC) in New York and designed by a group of investigators from the Dana-Farber Cancer Institute in Boston; the Mayo Clinic in Rochester, Minnesota; the University of North Carolina in Chapel Hill; and MSKCC (p. e236). The hypothesis was simply that proactive symptom monitoring during chemotherapy would improve symptom management and lead to better outcomes. For the study, 766 patients with advanced solid tumors who were receiving outpatient chemotherapy were randomized to a control arm with standard follow-up or to the intervention arm, on which patients self-reported on 12 common symptoms before and between visits using a web-based tool and received weekly e-mail reminders and nursing alerts. At 6 months, and compared with baseline, the self-reporting patients in the intervention arm experienced an improved quality of life (P < .001). In addition, 7% fewer of the self-reporting patients visited the emergency department (P = .02), and they experienced longer survival by 5 months compared with the standard follow-up group (31.2 vs 26.0 months, respectively; P = .03). Although there are limitations to such a study, the growth in technological advances should create the opportunity to expand on this strategy in further trials and in practice. With such an emphasis in the Medicare Oncology Home Model on decreasing hospital admissions and visits to the emergency department, there should great motivation for all involved to consider incorporating self-reporting into their patterns of care.
A continued emphasis on molecular profiling, personalized and/or precision medicine, and identifying or matching the patient to the best possible therapy or the most appropriate clinical trial remains vital to improving outcomes. Just before the ASCO meeting, the US Food and Drug Administration approved pembrolizumab for the treatment of patients with high-level microsatellite instability (MSI-H) and mismatch-repair deficient (dMMR) cancers, regardless of the site of origin. The approval was based on data from 149 patients with MSI-H or dMMR cancers, which showed a 40% response rate in this group of patients, two-thirds of whom had previously treated colon cancer. This landmark approval of a cancer therapy for a specific molecular profile and not the site of the disease, will certainly shape the future of oncology drug development. One of the highlighted stories at ASCO was the success of the larotrectinib (LOXO 101) tropomyosin receptor kinase inhibitor in patients with the TRK fusion mutations (p. e237). The data, including waterfall charts, swimmer plots, and computed-tomography scans, were impressive in this targeted population with a 76% response rate and a 91% duration of response at 6 months with a mild side effect profile.
In summary, across a variety of cancers, with treatment strategies of an equally diverse nature, we saw practice-changing data from the ASCO meeting that will benefit our patients. Continuing to seek out clinical trial options for patients will be critical in answering the many questions that have emerged and the substantial number of studies that are ongoing with combination immunotherapies, targeted small molecules, and a growing armamentarium of monoclonal antibodies.

The regimen was well tolerated overall, and it is clear that this option will be widely considered by physicians and their patients.
Two studies addressing the importance of managing symptoms and improving outcomes were also part of the plenary session. The IDEA Collaboration conducted a prospective pooled analysis of 6 phase 3 studies that assessed 3 and 6 months of oxaliplatin-based regimens for stage 3 colon cancer. FOLFOX and CAPOX given to 12,834 patients in 6 studies from the United States, European Union, Canada, Australia, New Zealand, and Japan were evaluated for DFS, treatment compliance, and adverse events. As would be anticipated, fewer side effects, particularly neurotoxicity, and greater compliance were observed in the 3-month group. Although DFS noninferiority for 3 months of therapy was not established statistically, the overall data led the investigators to issue a consensus statement advocating for a risk-based approach in deciding the duration of therapy and recommending 3 months of therapy for patients with stage 3, T1-3N1 disease, and consideration of 6 months therapy for T4 and/ or N2 disease. The investigators also acknowledged the leader and creator of IDEA, the late Daniel Sargent, PhD, of the Mayo Clinic, who passed away far too young after a brief illness last fall (1970-2016).
The second symptom-based study was performed at Memorial Sloan Kettering Cancer Center (MSKCC) in New York and designed by a group of investigators from the Dana-Farber Cancer Institute in Boston; the Mayo Clinic in Rochester, Minnesota; the University of North Carolina in Chapel Hill; and MSKCC (p. e236). The hypothesis was simply that proactive symptom monitoring during chemotherapy would improve symptom management and lead to better outcomes. For the study, 766 patients with advanced solid tumors who were receiving outpatient chemotherapy were randomized to a control arm with standard follow-up or to the intervention arm, on which patients self-reported on 12 common symptoms before and between visits using a web-based tool and received weekly e-mail reminders and nursing alerts. At 6 months, and compared with baseline, the self-reporting patients in the intervention arm experienced an improved quality of life (P < .001). In addition, 7% fewer of the self-reporting patients visited the emergency department (P = .02), and they experienced longer survival by 5 months compared with the standard follow-up group (31.2 vs 26.0 months, respectively; P = .03). Although there are limitations to such a study, the growth in technological advances should create the opportunity to expand on this strategy in further trials and in practice. With such an emphasis in the Medicare Oncology Home Model on decreasing hospital admissions and visits to the emergency department, there should great motivation for all involved to consider incorporating self-reporting into their patterns of care.
A continued emphasis on molecular profiling, personalized and/or precision medicine, and identifying or matching the patient to the best possible therapy or the most appropriate clinical trial remains vital to improving outcomes. Just before the ASCO meeting, the US Food and Drug Administration approved pembrolizumab for the treatment of patients with high-level microsatellite instability (MSI-H) and mismatch-repair deficient (dMMR) cancers, regardless of the site of origin. The approval was based on data from 149 patients with MSI-H or dMMR cancers, which showed a 40% response rate in this group of patients, two-thirds of whom had previously treated colon cancer. This landmark approval of a cancer therapy for a specific molecular profile and not the site of the disease, will certainly shape the future of oncology drug development. One of the highlighted stories at ASCO was the success of the larotrectinib (LOXO 101) tropomyosin receptor kinase inhibitor in patients with the TRK fusion mutations (p. e237). The data, including waterfall charts, swimmer plots, and computed-tomography scans, were impressive in this targeted population with a 76% response rate and a 91% duration of response at 6 months with a mild side effect profile.
In summary, across a variety of cancers, with treatment strategies of an equally diverse nature, we saw practice-changing data from the ASCO meeting that will benefit our patients. Continuing to seek out clinical trial options for patients will be critical in answering the many questions that have emerged and the substantial number of studies that are ongoing with combination immunotherapies, targeted small molecules, and a growing armamentarium of monoclonal antibodies.
FDA clears first 2D mammography device with patient-controlled compression
The Food and Drug Administration has granted premarket clearance to the first 2D digital mammography system that allows patients to control the amount of compression applied to their own breasts before the mammogram x-ray is taken.
Senographe Pristina with Self-Compression uses a handheld wireless remote control that allows women to adjust the compression force after breast positioning and during a mammography exam. The technologist positions the patient and initiates compression, then guides the patient to gradually increase compression using the remote control until adequate compression is reached. The technologist checks the applied compression and breast positioning and makes the final decision on whether the compression is adequate or needs to be adjusted, according to the FDA’s Sept. 1 announcement.
“Regular mammograms are an important tool in detecting breast cancer,” Alberto Gutierrez, PhD, director of the FDA’s Office of In Vitro Diagnostics and Radiological Health, said in a statement. “However, some patients may experience anxiety or stress about the discomfort from the compression during the mammogram. This device allows patients some control over the amount of compression for their exam.”

2017 Update on female sexual dysfunction
Sexual function is a complex, multifaceted process mediated by neurologic functions, hormonal regulation, and ps
As it turns out, quite a lot. Female sexual dysfunction is a common, vastly undertreated sexual health problem that can have wide-reaching effects on a woman’s life. These effects may include impaired body image, self-confidence, and self-worth. Sexual dysfunction also can contribute to relationship dissatisfaction and leave one feeling less connected with her partner.1,2 Studies have shown women with sexual dysfunction have higher health care expenditures3 and that depression and fatigue are common comorbidities, as is frequently seen in other chronic conditions such as diabetes and back pain.4
Understanding the pathogenesis of female sexual dysfunction helps to guide our approach to its management. Indeed, increased understanding of its pathology has helped to usher in new and emerging treatment options, as well as a personalized, biopsychosocial approach to its management.

2016 Update on female sexual dysfunction
In this Update, I discuss the interplay of physiologic and psychological factors that affect female sexual function as well as the latest options for its management. I have also assembled a panel of experts to discuss 2 cases representative of sexual dysfunction that you may encounter in your clinical practice and how prescribing decisions are made for their management.
Read about factors that impact sexual function and agents to help manage dysfunction.
Multiple transmitters in the brain can increase or decrease sexual desire and function
Neurotransmitters involved in sexual excitation include brain dopamine, melanocortin, oxytocin, vasopressin, and norepinephrine, whereas brain opioids, serotonin, prolactin, and endocannabinoids function as sexual inhibitors. Inhibitory transmitters are activated normally during sexual refractoriness but also from primary aversion or secondary avoidance disorders.1 Drugs or conditions that reduce brain dopamine levels, increase the action of brain serotonin, or enhance brain opioid pathways have been shown to inhibit sexual desire, while those that increase hypothalamic and mesolimbic dopamine or decrease serotonin release have been shown to stimulate sexual desire.1
Estradiol and progesterone can impact sexual function and desire
In addition to the neurotransmitters, hormones are important modulators of female sexual function. Decreasing levels of circulating estrogen after menopause lead to physiologic, biologic, and clinical changes in the urogenital tissues, such as decreased elastin, thinning of the epithelium, reduced vaginal blood flow, diminished lubrication, and decreased flexibility and elasticity. These changes result in the symptoms of genitourinary syndrome of menopause (GSM), which affects as many as half of all menopausal women.5,6 In clinical trials, dyspareunia and vaginal dryness are the most bothersome GSM symptoms reported.7
The role of hormonal regulation in sexual dysfunction among premenopausal women is not yet fully understood, but we do know that estradiol has been shown to improve sexual desire, progesterone tends to dampen sexual desire, and that testosterone at physiological levels has been shown in most studies to have a neutral effect on sexual desire in a well-estrogenized patient.8

Experience and behavior modulate or reinforce sexual dysfunction
The most common psychological factors that trigger or amplify female sexual dysfunction are depression, anxiety, distraction, negative body image, sexual abuse, and emotional neglect.9 Contextual or sociocultural factors, such as relationship discord, life-stage stressors (the empty nest syndrome or anxiety and sleep deprivation from a new baby), as well as cultural or religious values that suppress sexuality, also should be considered.9 Experience-based neuroplasticity (changes in brain pathways that become solidified by negative or positive experiences) may elucidate how a multimodal approach, utilizing medical and psychological treatment, can be beneficial for patients, particularly those with hypoactive sexual desire disorder (HSDD).1
New and emerging approaches to managing female sexual dysfunction
Three agents, one of which has been available for prescription for some time, one that is newly available, and one in the pipeline, are or may soon be in the gynecologist's armamentarium.
Flibanserin
Medications that target excitatory pathways or blunt inhibitory pathways are in development, and one, flibanserin (Addyi), has been US Food and Drug Administration (FDA)-approved for the treatment of acquired, generalized HSDD in premenopausal women.1,10 Flibanserin is a nonhormonal, centrally acting, postsynaptic serotonin 1A receptor agonist and a serotonin 2A receptor antagonist that is taken daily at bedtime (100 mg); several weeks are usually needed before any effects are noted.1 It is not approved for postmenopausal women and has a boxed warning about the risks of hypotension and syncope; its use is contraindicated in women who drink alcohol, in those who have hepatic impairment, and with the use of moderate or strong CYP3A4 inhibitors.11
Also keep in mind that flibanserin is only available through a Risk Evaluation and Mitigation Strategy program, so clinicians who wish to prescribe it must enroll in and complete training to become certified providers.9

What you need to know (and do) to prescribe the new drug flibanserin
Prasterone
Prasterone (Intrarosa), a once-daily intravaginal dehydroepiandrosterone (DHEA) product, is a prohormone that increases local estrogen and testosterone and has the advantage of improved sexual function, desire, arousal, lubrication, orgasm, satisfaction, as well as pain at sexual activity.12 It was approved by the FDA in November 2016 to treat moderate to severe dyspareunia and has been available for prescribing since July 2017. Its cost is comparable to topical estrogen products, with a $25 copay program.
Because prasterone is not an estrogen, it does not have the boxed warning that all estrogen products are mandated by the FDA to have. This may make it more acceptable to patients, who often decline to use an estrogen product after seeing the boxed warning on the package. The Centers for Medicare and Medicaid Services (CMS) does not have prasterone on its list of potentially hazardous drugs for the elderly. However, keep in mind that because its label is for dyspareunia and not specifically for GSM, CMS considers it a drug of choice--in other words, like sildenafil (Viagra), a lifestyle choice and not for treatment of a medical condition. As such, at the present time, Medicare does not cover it.
Bremelanotide
Late-stage trials of bremelanotide, a melanocortin receptor agonist, are underway. Its mechanism of action is somewhat like that of flibanserin in that both drugs increase dopamine and norepinephrine levels. The advantage of bremelanotide is that it is used as needed. It is dosed subcutaneously (1.75 mg) and it can be used as often as a woman would like to use it. The FDA is expected to consider it for approval in about a year. Unpublished data from poster sessions at recent meetings show that, in a phase 3 study of 1,247 premenopausal women with HSDD (who had already been screened for depression and were found to have a physiologic condition), improvements in desire, arousal, lubrication, and orgasm were shown with bremelanotide. About 18% of women stopped using the drug because of adverse effects (nausea, vomiting, flushing, or headache) versus 2% for placebo. Like flibanserin, it is expected to be approved for premenopausal women only.
Read how 3 experts would manage differing GSM symptoms.
What would you prescribe for these patients?
CASE Genitourinary syndrome of menopause (GSM) in a 55-year-old woman
A 55-year-old widow is beginning a new relationship. She has not had partnered sexual activity for several years, but she recently has begun a relationship. She describes pain with attempted penetration with her new partner. Her last menstrual period was 3 years ago and she has experienced very minor menopausal symptoms, which are not bothersome. On examination, the vulva and vagina are pale, with thin epithelium and absent rugae. The tissue lacks elasticity. A virginal speculum is needed to visualize the cervix.
How would you go about deciding which of the many options for management of GSM you will recommend for this patient? What do you weigh as you consider DHEA versus estrogen and topical versus oral therapy?
JoAnn V. Pinkerton, MD: Vulvovaginal atrophy (VVA), part of GSM, is associated with postmenopausal estrogen deficiency and includes the signs and symptoms seen on this patient's physical exam: vaginal narrowing, pallor, loss of elasticity, as well as pain with intercourse.6 Estrogen therapy is the most effective treatment for vaginal atrophy.13 Since she does not have significant menopausal symptoms, low-dose vaginal estrogen preparations are effective and generally safe treatments for VVA; these include creams, tablets containing estradiol or conjugated equine estrogen (CEE), and a low-dose vaginal estradiol ring--all available at doses that result in minimal systemic absorption.
Choice is usually made based on patient desire and likely adherence. If the patient prefers nonestrogen therapies that improve VVA and have been approved for relief of dyspareunia in postmenopausal women, I would discuss with the patient the oral selective estrogen receptor modulator ospemifene,14 and the new intravaginal DHEA suppositories, prasterone.15 Ospemifene is taken daily as an oral tablet, has a small risk of blood clots, and is my choice for women who do not need systemic hormone therapy and prefer to avoid vaginal therapy.
Andrew M. Kaunitz, MD: GSM is prevalent in menopausal women and, if not treated, causes progressive vaginal dryness and sexual discomfort. When the main indication for hormonal management in a menopausal woman is GSM (as opposed to treatment of vasomotor symptoms or prevention of osteoporosis), the treatment of choice is low-dose local vaginal estrogen, ospemifene, or prasterone (DHEA). Prasterone is a vaginally administered nonestrogen steroid that was approved by the FDA to treat dyspareunia associated with GSM. DHEA is an endogenous inactive steroid that is converted locally into androgens and estrogens; one vaginal insert is placed nightly.16,17
This 55-year-old widow has not been sexually active for some time. The facts that attempted penetration was painful and only an ultrathin (virginal) speculum could be used for examination indicate that contraction of the pelvic floor muscles is likely present. Simply starting medical management may not lead to comfortable/successful penetrative sex for this woman. In addition to medical management, she would likely benefit from referral for physical therapy. Using dilators and other strategies, along with the positive impact that medical management will have on the vaginal mucosa, a woman's physical therapist can work with this patient to help the pelvic floor muscles relax and facilitate comfortable penetrative sex.
James A. Simon, MD: With only minor vasomotor symptoms, I would assess the other potential benefits of a systemic therapy. These might include cardiovascular risk reduction (systemic estrogens or estrogens/progesterone in some), breast cancer risk reduction (some data suggesting ospemifene can accomplish this), osteoporosis prevention (systemic estrogens and estrogen/androgens), etc. If there is an option for a treatment to address more than one symptom, in this case GSM, assessing the risks/benefits of each of these therapies should be estimated for this specific patient.
If there are no systemic benefits to be had, then any of the local treatments should be helpful. As there are no head-to-head comparisons available, local estrogen cream, tablets, rings, local DHEA, or systemic ospemifene each should be considered possible treatments. I also feel this patient may benefit from supplementary self-dilation and/or physical therapy.

CASE Dyspareunia and vasomotor symptoms in a 42-year-old breast cancer survivor
A 42-year-old woman with a BRCA1 mutation has undergone prophylactic mastectomies as well as hysterectomy with bilateral salpingo-oophorectomy. She reports mild to moderate hot flashes and bothersome vaginal dryness and dyspareunia. Examination confirms GSM.
Would you advise systemic hormone therapy for this patient? What would your recommendation be for management of her GSM symptoms?
Dr. Simon: While one's gut reaction would be to avoid systemic estrogen therapy in a patient with a BRCA1 mutation, the scientific information confirming this fear is lacking.18 Such patients may benefit significantly from systemic estrogen therapy (reduced risk of cardiovascular disease and cognitive decline, etc.), and with both breasts and both ovaries removed, estrogen's breast cancer risks, if any in this population, are largely avoided. The patient also may benefit from additional local therapy with either estrogens or DHEA.
Dr. Kaunitz: Due to her high lifetime risk of breast and ovarian cancer, this woman has proceeded with risk-reducing breast and gynecologic surgery. As more BRCA mutation carriers are being identified and undergo risk-reducing bilateral mastectomy (usually with reconstruction) and salpingo-oophorectomy, clinicians and mutation carriers more frequently face decisions regarding use of systemic hormone therapy.
Mutation carriers who have undergone bilateral risk-reducing mastectomy experience a very low baseline future risk for breast cancer; accordingly, concerns regarding this disease should not prevent use of systemic hormone therapy. Furthermore, without hormone replacement, induced menopause in women this age is associated with an elevated risk of osteoporosis, persistent vasomotor symptoms, cardiovascular disease, stroke, mood changes, dementia, Parkinson disease, and overall mortality. Recognizing the safety of estrogen therapy in this setting, this 42-year-old BRCA1 mutation carrier can initiate estrogen therapy. Standard dose estrogen therapy refers to oral estradiol 1.0 mg, conjugated equine estrogen 0.625 mg,or transdermal estradiol 0.05 mg. In younger women like this 42-year-old with surgically induced menopause, higher than standard replacement doses of estrogen are often appropriate.17
Due to concerns the hormone therapy might further increase future risk of breast cancer, some mutation carriers may delay or avoid risk-reducing bilateral salpingo-oophorectomy, a potentially lifesaving surgery which reduces not only future risk of ovarian cancer but also future risk for breast cancer.
Among mutation carriers with intact breasts, several studies address risk of breast cancer with use of systemic hormone therapy. Although limited in numbers of participants and years of follow-up, in aggregate, these studies provide reassurance that short-term use of systemic hormone therapy does not increase breast cancer risk in women with BRCA1 or BRCA2 mutations and intact breasts.19
Dr. Pinkerton: For this woman with early surgical menopause and hysterectomy, estrogen therapy could improve her vasomotor symptoms and decrease her risk of bone loss and GSM.17 In the Women's Health Initiative trial, there were 7 fewer breast cancers per 10,000 women-years in the estrogen-onlyarm.20 Observational studies suggest that hormone therapy, when given to the average age of menopause, decreases the risks of heart disease, Parkinson disease, and dementia.21 Limited observational evidence suggests that hormone therapy use does not further increase risk of breast cancer in women following oophorectomy for BRCA1 or BRCA2 gene mutation.22
The absolute risks observed with hormone therapy tended to be small, especially in younger, healthy women. Systemic hormone therapy could treat her hot flashes and her GSM symptoms and potentially decrease health risks associated with premature estrogen deficiency. Nonestrogen therapies for hot flashes include low-dose antidepressants, gabapentin, and mind-body options, such as cognitive behavioral therapy and hypnosis, but these would not decrease her health risks or treat her GSM.
If she only requests treatment of her GSM symptoms, she would be a candidate for low-dose vaginal estrogen therapy, given as a cream, tablet, or ring depending on her choice. I would not choose ospemifene as my first choice as she is having hot flashes, and there are no data yet on the drug's health benefits in early menopause. If she prefers nonestrogen vaginal therapy, the new intravaginal DHEA might be a good choice as both estrogen and testosterone are increased locally in the vagina while hormone levels remain in the postmenopausal range. There is no boxed warning on the patient insert, although safety in women with breast cancer or in those with elevated risk of breast cancer has not been tested.

However, keep in mind that because its label is for dyspareunia and not specifically for GSM, CMS considers it a drug of choice--in other words, like sildenafil (Viagra), a lifestyle choice and not for treatment of a medical condition. As such, at the present time, Medicare does not cover it.
Bremelanotide
Late-stage trials of bremelanotide, a melanocortin receptor agonist, are underway. Its mechanism of action is somewhat like that of flibanserin in that both drugs increase dopamine and norepinephrine levels. The advantage of bremelanotide is that it is used as needed. It is dosed subcutaneously (1.75 mg) and it can be used as often as a woman would like to use it. The FDA is expected to consider it for approval in about a year. Unpublished data from poster sessions at recent meetings show that, in a phase 3 study of 1,247 premenopausal women with HSDD (who had already been screened for depression and were found to have a physiologic condition), improvements in desire, arousal, lubrication, and orgasm were shown with bremelanotide. About 18% of women stopped using the drug because of adverse effects (nausea, vomiting, flushing, or headache) versus 2% for placebo. Like flibanserin, it is expected to be approved for premenopausal women only.

CASE Genitourinary syndrome of menopause (GSM) in a 55-year-old woman
A 55-year-old widow is beginning a new relationship. She has not had partnered sexual activity for several years, but she recently has begun a relationship. She describes pain with attempted penetration with her new partner. Her last menstrual period was 3 years ago and she has experienced very minor menopausal symptoms, which are not bothersome. On examination, the vulva and vagina are pale, with thin epithelium and absent rugae. The tissue lacks elasticity. A virginal speculum is needed to visualize the cervix.
How would you go about deciding which of the many options for management of GSM you will recommend for this patient? What do you weigh as you consider DHEA versus estrogen and topical versus oral therapy?
JoAnn V. Pinkerton, MD: Vulvovaginal atrophy (VVA), part of GSM, is associated with postmenopausal estrogen deficiency and includes the signs and symptoms seen on this patient's physical exam: vaginal narrowing, pallor, loss of elasticity, as well as pain with intercourse.6 Estrogen therapy is the most effective treatment for vaginal atrophy.13 Since she does not have significant menopausal symptoms, low-dose vaginal estrogen preparations are effective and generally safe treatments for VVA; these include creams, tablets containing estradiol or conjugated equine estrogen (CEE), and a low-dose vaginal estradiol ring--all available at doses that result in minimal systemic absorption.
Choice is usually made based on patient desire and likely adherence. If the patient prefers nonestrogen therapies that improve VVA and have been approved for relief of dyspareunia in postmenopausal women, I would discuss with the patient the oral selective estrogen receptor modulator ospemifene,14 and the new intravaginal DHEA suppositories, prasterone.15 Ospemifene is taken daily as an oral tablet, has a small risk of blood clots, and is my choice for women who do not need systemic hormone therapy and prefer to avoid vaginal therapy.
Andrew M. Kaunitz, MD: GSM is prevalent in menopausal women and, if not treated, causes progressive vaginal dryness and sexual discomfort. When the main indication for hormonal management in a menopausal woman is GSM (as opposed to treatment of vasomotor symptoms or prevention of osteoporosis), the treatment of choice is low-dose local vaginal estrogen, ospemifene, or prasterone (DHEA). Prasterone is a vaginally administered nonestrogen steroid that was approved by the FDA to treat dyspareunia associated with GSM. DHEA is an endogenous inactive steroid that is converted locally into androgens and estrogens; one vaginal insert is placed nightly.16,17
This 55-year-old widow has not been sexually active for some time. The facts that attempted penetration was painful and only an ultrathin (virginal) speculum could be used for examination indicate that contraction of the pelvic floor muscles is likely present. Simply starting medical management may not lead to comfortable/successful penetrative sex for this woman. In addition to medical management, she would likely benefit from referral for physical therapy. Using dilators and other strategies, along with the positive impact that medical management will have on the vaginal mucosa, a woman's physical therapist can work with this patient to help the pelvic floor muscles relax and facilitate comfortable penetrative sex.
James A. Simon, MD: With only minor vasomotor symptoms, I would assess the other potential benefits of a systemic therapy. These might include cardiovascular risk reduction (systemic estrogens or estrogens/progesterone in some), breast cancer risk reduction (some data suggesting ospemifene can accomplish this), osteoporosis prevention (systemic estrogens and estrogen/androgens), etc. If there is an option for a treatment to address more than one symptom, in this case GSM, assessing the risks/benefits of each of these therapies should be estimated for this specific patient.
If there are no systemic benefits to be had, then any of the local treatments should be helpful. As there are no head-to-head comparisons available, local estrogen cream, tablets, rings, local DHEA, or systemic ospemifene each should be considered possible treatments. I also feel this patient may benefit from supplementary self-dilation and/or physical therapy.

CASE Dyspareunia and vasomotor symptoms in a 42-year-old breast cancer survivor
A 42-year-old woman with a BRCA1 mutation has undergone prophylactic mastectomies as well as hysterectomy with bilateral salpingo-oophorectomy. She reports mild to moderate hot flashes and bothersome vaginal dryness and dyspareunia. Examination confirms GSM.
Would you advise systemic hormone therapy for this patient? What would your recommendation be for management of her GSM symptoms?
Dr. Simon: While one's gut reaction would be to avoid systemic estrogen therapy in a patient with a BRCA1 mutation, the scientific information confirming this fear is lacking.18 Such patients may benefit significantly from systemic estrogen therapy (reduced risk of cardiovascular disease and cognitive decline, etc.), and with both breasts and both ovaries removed, estrogen's breast cancer risks, if any in this population, are largely avoided. The patient also may benefit from additional local therapy with either estrogens or DHEA.
Dr. Kaunitz: Due to her high lifetime risk of breast and ovarian cancer, this woman has proceeded with risk-reducing breast and gynecologic surgery. As more BRCA mutation carriers are being identified and undergo risk-reducing bilateral mastectomy (usually with reconstruction) and salpingo-oophorectomy, clinicians and mutation carriers more frequently face decisions regarding use of systemic hormone therapy.
Mutation carriers who have undergone bilateral risk-reducing mastectomy experience a very low baseline future risk for breast cancer; accordingly, concerns regarding this disease should not prevent use of systemic hormone therapy. Furthermore, without hormone replacement, induced menopause in women this age is associated with an elevated risk of osteoporosis, persistent vasomotor symptoms, cardiovascular disease, stroke, mood changes, dementia, Parkinson disease, and overall mortality. Recognizing the safety of estrogen therapy in this setting, this 42-year-old BRCA1 mutation carrier can initiate estrogen therapy. Standard dose estrogen therapy refers to oral estradiol 1.0 mg, conjugated equine estrogen 0.625 mg,or transdermal estradiol 0.05 mg. In younger women like this 42-year-old with surgically induced menopause, higher than standard replacement doses of estrogen are often appropriate.17
Due to concerns the hormone therapy might further increase future risk of breast cancer, some mutation carriers may delay or avoid risk-reducing bilateral salpingo-oophorectomy, a potentially lifesaving surgery which reduces not only future risk of ovarian cancer but also future risk for breast cancer.
Among mutation carriers with intact breasts, several studies address risk of breast cancer with use of systemic hormone therapy. Although limited in numbers of participants and years of follow-up, in aggregate, these studies provide reassurance that short-term use of systemic hormone therapy does not increase breast cancer risk in women with BRCA1 or BRCA2 mutations and intact breasts.19
Dr. Pinkerton: For this woman with early surgical menopause and hysterectomy, estrogen therapy could improve her vasomotor symptoms and decrease her risk of bone loss and GSM.17 In the Women's Health Initiative trial, there were 7 fewer breast cancers per 10,000 women-years in the estrogen-onlyarm.20 Observational studies suggest that hormone therapy, when given to the average age of menopause, decreases the risks of heart disease, Parkinson disease, and dementia.21 Limited observational evidence suggests that hormone therapy use does not further increase risk of breast cancer in women following oophorectomy for BRCA1 or BRCA2 gene mutation.22
The absolute risks observed with hormone therapy tended to be small, especially in younger, healthy women. Systemic hormone therapy could treat her hot flashes and her GSM symptoms and potentially decrease health risks associated with premature estrogen deficiency. Nonestrogen therapies for hot flashes include low-dose antidepressants, gabapentin, and mind-body options, such as cognitive behavioral therapy and hypnosis, but these would not decrease her health risks or treat her GSM.
If she only requests treatment of her GSM symptoms, she would be a candidate for low-dose vaginal estrogen therapy, given as a cream, tablet, or ring depending on her choice. I would not choose ospemifene as my first choice as she is having hot flashes, and there are no data yet on the drug's health benefits in early menopause. If she prefers nonestrogen vaginal therapy, the new intravaginal DHEA might be a good choice as both estrogen and testosterone are increased locally in the vagina while hormone levels remain in the postmenopausal range. There is no boxed warning on the patient insert, although safety in women with breast cancer or in those with elevated risk of breast cancer has not been tested.

Sexual function is a complex, multifaceted process mediated by neurologic functions, hormonal regulation, and ps
As it turns out, quite a lot. Female sexual dysfunction is a common, vastly undertreated sexual health problem that can have wide-reaching effects on a woman’s life. These effects may include impaired body image, self-confidence, and self-worth. Sexual dysfunction also can contribute to relationship dissatisfaction and leave one feeling less connected with her partner.1,2 Studies have shown women with sexual dysfunction have higher health care expenditures3 and that depression and fatigue are common comorbidities, as is frequently seen in other chronic conditions such as diabetes and back pain.4
Understanding the pathogenesis of female sexual dysfunction helps to guide our approach to its management. Indeed, increased understanding of its pathology has helped to usher in new and emerging treatment options, as well as a personalized, biopsychosocial approach to its management.

2016 Update on female sexual dysfunction
In this Update, I discuss the interplay of physiologic and psychological factors that affect female sexual function as well as the latest options for its management. I have also assembled a panel of experts to discuss 2 cases representative of sexual dysfunction that you may encounter in your clinical practice and how prescribing decisions are made for their management.
Read about factors that impact sexual function and agents to help manage dysfunction.
Multiple transmitters in the brain can increase or decrease sexual desire and function
Neurotransmitters involved in sexual excitation include brain dopamine, melanocortin, oxytocin, vasopressin, and norepinephrine, whereas brain opioids, serotonin, prolactin, and endocannabinoids function as sexual inhibitors. Inhibitory transmitters are activated normally during sexual refractoriness but also from primary aversion or secondary avoidance disorders.1 Drugs or conditions that reduce brain dopamine levels, increase the action of brain serotonin, or enhance brain opioid pathways have been shown to inhibit sexual desire, while those that increase hypothalamic and mesolimbic dopamine or decrease serotonin release have been shown to stimulate sexual desire.1
Estradiol and progesterone can impact sexual function and desire
In addition to the neurotransmitters, hormones are important modulators of female sexual function. Decreasing levels of circulating estrogen after menopause lead to physiologic, biologic, and clinical changes in the urogenital tissues, such as decreased elastin, thinning of the epithelium, reduced vaginal blood flow, diminished lubrication, and decreased flexibility and elasticity. These changes result in the symptoms of genitourinary syndrome of menopause (GSM), which affects as many as half of all menopausal women.5,6 In clinical trials, dyspareunia and vaginal dryness are the most bothersome GSM symptoms reported.7
The role of hormonal regulation in sexual dysfunction among premenopausal women is not yet fully understood, but we do know that estradiol has been shown to improve sexual desire, progesterone tends to dampen sexual desire, and that testosterone at physiological levels has been shown in most studies to have a neutral effect on sexual desire in a well-estrogenized patient.8

Experience and behavior modulate or reinforce sexual dysfunction
The most common psychological factors that trigger or amplify female sexual dysfunction are depression, anxiety, distraction, negative body image, sexual abuse, and emotional neglect.9 Contextual or sociocultural factors, such as relationship discord, life-stage stressors (the empty nest syndrome or anxiety and sleep deprivation from a new baby), as well as cultural or religious values that suppress sexuality, also should be considered.9 Experience-based neuroplasticity (changes in brain pathways that become solidified by negative or positive experiences) may elucidate how a multimodal approach, utilizing medical and psychological treatment, can be beneficial for patients, particularly those with hypoactive sexual desire disorder (HSDD).1
New and emerging approaches to managing female sexual dysfunction
Three agents, one of which has been available for prescription for some time, one that is newly available, and one in the pipeline, are or may soon be in the gynecologist's armamentarium.
Flibanserin
Medications that target excitatory pathways or blunt inhibitory pathways are in development, and one, flibanserin (Addyi), has been US Food and Drug Administration (FDA)-approved for the treatment of acquired, generalized HSDD in premenopausal women.1,10 Flibanserin is a nonhormonal, centrally acting, postsynaptic serotonin 1A receptor agonist and a serotonin 2A receptor antagonist that is taken daily at bedtime (100 mg); several weeks are usually needed before any effects are noted.1 It is not approved for postmenopausal women and has a boxed warning about the risks of hypotension and syncope; its use is contraindicated in women who drink alcohol, in those who have hepatic impairment, and with the use of moderate or strong CYP3A4 inhibitors.11
Also keep in mind that flibanserin is only available through a Risk Evaluation and Mitigation Strategy program, so clinicians who wish to prescribe it must enroll in and complete training to become certified providers.9

What you need to know (and do) to prescribe the new drug flibanserin
Prasterone
Prasterone (Intrarosa), a once-daily intravaginal dehydroepiandrosterone (DHEA) product, is a prohormone that increases local estrogen and testosterone and has the advantage of improved sexual function, desire, arousal, lubrication, orgasm, satisfaction, as well as pain at sexual activity.12 It was approved by the FDA in November 2016 to treat moderate to severe dyspareunia and has been available for prescribing since July 2017. Its cost is comparable to topical estrogen products, with a $25 copay program.
Because prasterone is not an estrogen, it does not have the boxed warning that all estrogen products are mandated by the FDA to have. This may make it more acceptable to patients, who often decline to use an estrogen product after seeing the boxed warning on the package. The Centers for Medicare and Medicaid Services (CMS) does not have prasterone on its list of potentially hazardous drugs for the elderly. However, keep in mind that because its label is for dyspareunia and not specifically for GSM, CMS considers it a drug of choice--in other words, like sildenafil (Viagra), a lifestyle choice and not for treatment of a medical condition. As such, at the present time, Medicare does not cover it.
Bremelanotide

Focus on lifestyle to manage menopause symptoms after breast cancer
Lifestyle modification, rather than hormone therapy, should form the basis for managing estrogen-depletion symptoms and associated clinical problems in breast cancer survivors, according to a review of available evidence.
The review, conducted by the writing group for the Endocrine Society’s guidelines on management of menopausal symptoms, was prompted by the paucity of both randomized controlled trials in breast cancer survivors with estrogen deficiency issues and guidelines that sufficiently focus on treatment of this subgroup of women.
“A large proportion of women experience menopausal symptoms or clinical manifestations of estrogen deficiency during treatment of their breast cancer or after completion of therapy. The specific symptoms and clinical challenges differ based on menopausal status prior to initiation of cancer treatment and therapeutic agents used,” the researchers wrote in a report published in the Journal of Clinical Endocrinology & Metabolism (2017 Aug 2. doi: 10.1210/jc.2017-01138).
For instance, among premenopausal women treated with chemotherapy, ovarian insufficiency, severe menopausal symptoms, and infertility can result. Postmenopasual women treated with aromatase inhibitors may experience arthralgia, accelerated bone loss, and osteoporotic fractures, as well as severe vulvovaginal atrophy, they explained, noting that both premenopausal and postmenopausal survivors can experience moderate-to-severe vasomotor symptoms and sleep disturbance with related fatigue, depressive symptoms, and mood changes.
“Less common problems include weight gain, symptomatic osteoarthritis and intervertebral disk degeneration, degenerative skin changes, radiation and chemotherapy-related cardiovascular disease, and reduced quality of life,” the researchers wrote.
Based on a review of randomized controlled clinical trials, observational studies, evidence-based guidelines, and expert opinion from professional societies, the writing group concluded that individualized lifestyle modifications and nonpharmacologic therapies are recommended for the treatment of these symptoms.
Specifically, the writing group recommended smoking cessation, weight loss when indicated, limited alcohol intake, maintenance of adequate vitamin D and calcium levels, a healthy diet, and regular physical activity for all women with prior breast cancer.
They also recommended nonpharmacologic therapies for vasomotor symptoms, and noted that cognitive behavioral therapy, hypnosis, and acupuncture are among the approaches that may be helpful.
Vaginal lubricants and moisturizers can also be helpful for mild vulvovaginal atrophy, they wrote. For women with more severe symptoms or signs of estrogen deficiency, pharmacologic agents are available to relieve vasomotor symptoms and vulvovaginal atrophy, and to prevent and treat fractures, they wrote, adding that “therapy must be individualized based on each woman’s needs and goals for therapy.”
Among emerging approaches to treatment of symptoms are selective estrogen receptor modulators (SERMs), tissue selective estrogen complex (TSEC) therapy, estetrol, and neurokinin B inhibitors, which show promise for expanding options for symptom relief with less breast cancer risk. However, these have not yet been tested in women with prior breast cancer, the researchers noted.

FDA expands approval of fulvestrant for HR+/HER2– advanced breast cancer
The Food and Drug Administration has approved fulvestrant (Faslodex) as monotherapy for women with hormone receptor–positive, human epidermal growth factor receptor 2–negative (HR+/HER2–) advanced breast cancer who are postmenopausal and previously untreated.
Approval was based on improved progression-free survival (PFS) in the phase 3 FALCON trial of 462 postmenopausal women with HR+/HER2– metastatic or locally advanced breast cancer who had not previously received hormonal therapy, drug maker AstraZeneca said in a press release.
The most common adverse events were arthralgia (16.7% of patients on fulvestrant vs. 10.3% on anastrozole), and hot flushes/flashes (11.4% vs. 10.3%).
Grade 3 or greater adverse events occurred in 22.4% vs. 17.7%. Deaths from adverse events occurred in six patients on fulvestrant vs. seven on anastrozole, according to results published in The Lancet.

Annual mammograms from age 40 linked with greatest reductions in mortality
Annual mammograms starting at age 40 and continuing until age 84 will achieve the greatest reductions in breast cancer deaths, according to a modeling study published in Cancer.
Researchers used Cancer Intervention and Surveillance Modeling Network (CISNET) breast cancer models to compare three current mammography-based screening approaches for women at average risk of breast cancer. The first approach is for annual screening from ages 40-84 years, the second is a hybrid approach with annual screening from ages 45 to 54 then biennial screening from ages 55 to 79, and the third approach involves biennial mammograms from ages 50 to 74.
The modeling suggested that the largest mean reduction in mortality – 36.9% – was associated with annual screening starting at age 40. The second largest reduction of 30.8% occurred with the hybrid screening approach starting at age 45, while the smallest reduction in mortality – 23.2% – occurred with biennial screening starting at age 50 (Cancer 2017 Aug 21. doi: 10.1002/cncr.30842).
Annual screening also averted the most deaths from breast cancer – 11.9 per 1,000 women screened – and gained the most life-years (189 per 1,000 women screened, compared with 149 for the hybrid approach and 110 for biennial screening), reported Elizabeth K. Arleo, MD, of Weill Cornell Imaging at New York–Presbyterian, New York, and her coauthors.
However, the annual screening approach was also associated with the largest number of benign recalls and benign biopsies. The model suggested that a woman starting annual screening from age 40 could expect on average to be recalled for a benign diagnostic work-up every 13 years and undergo a benign biopsy every 187 years.
Overall, using a single-year cohort of women born in 1960 who were 100% compliant with screening, the model predicted that 44,671 would still die of breast cancer with annual screening, 51,211 would die under the hybrid screening model, and 56,887 would die under the biennial screening model.
“If the goal is to avert the most breast cancer deaths and gain the most life-years, CISNET modeling shows that the optimal age of initiation for screening mammography is 40 years, the optimal screening frequency is annual, and the optimal stopping age is when a woman’s life expectancy is less than 5-7 years,” the researchers wrote. “Individual women should continue to have the choice to reduce their risk of dying from breast cancer as much as possible, and as CISNET models show, annual mammography starting at age 40 years is the best way to do so.”
Two of the researchers reported consulting or institutional support from GE Healthcare. No other conflicts of interest were reported.
