Conference Coverage

Many women with cancer want advice for managing sexual function issues, and clinicians are tuning in, new studies suggest.

Decreased sexual function is a side effect of many types of cancer, notably uterine, cervical, ovarian, and breast cancer, that often goes unaddressed, according to the authors of several studies presented at the Society of Gynecologic Oncology (SGO)’s Annual Meeting on Women’s Cancer.

Patients want to talk about sex, but not necessarily at the start of their diagnosis or treatment, suggest the findings of a study presented at the meeting. Jesse T. Brewer of Weill Cornell Medicine in New York City and colleagues enrolled 63 patients who underwent surgery with documented hereditary breast cancer, ovarian cancer, or Lynch syndrome in a cross-sectional survey.

Overall, 86% said that sexuality and intimacy were very or somewhat important, and 78% said that the healthcare team addressing the issue was very or somewhat important, the researchers found. However, only 40% of the respondents said that they wanted to discuss sexuality at the time of diagnosis because the idea was too overwhelming.

Oncologists are more aware of sexual side effects and the potential for sexual issues that persist long after treatment, but many patients may not have opportunities to talk about sexual concerns, said Don S. Dizon, MD, an oncologist specializing in women’s cancers at Brown University, Providence, Rhode Island, in an interview.

“It is important that we [oncologists] be the ones to open the door to these conversations; people with cancer will not bring it up spontaneously, for fear of making their provider uncomfortable, especially if they’ve never been asked about it before,” Dr. Dizon said in an interview.

He advised clinicians to find a network within their health systems so they can refer patients to specialized services, such as sex therapy, couples counseling, pelvic rehabilitation, or menopausal experts as needed.

In another study presented at the meeting, Naaman Mehta, MD, of NYU Langone Health, and colleagues reviewed data from 166 healthcare providers who completed a 23-item survey about evaluating and managing sexual health concerns of their patients. Most of the respondents were gynecologic oncologists (93.4%), but one radiation oncologist and 10 other healthcare providers also completed the survey.

Overall, approximately 60% of the respondents routinely asked about the sexual health concerns of their patients, and 98% of these said they believed that sexual health discussions should be held with a gynecologic oncologist. Just over half (54%) also said that the patient should be the one to initiate a discussion of sexual health concerns.

Female providers were significantly more likely to discuss sexual health with patients, compared with male providers, after controlling for the hospital setting and training level, the researchers noted (odds ratio, 1.4;P < .01).

The results suggest a need for more ways to integrate sexual health screening into gynecologic oncologic clinics, the researchers concluded.

The provider survey findings are similar to the results of a survey conducted by Dr. Dizon and colleagues in 2007. In that study, less than half of respondents took a sexual history, but 80% felt there was insufficient time to explore sexual issues.

“It is critical to understand that people with cancer do not expect their oncologists to be sexual health experts, but as with all other side effects caused by treatment and the diagnosis, we can be the ones who recognize it,” Dr. Dizon noted, in an interview.
 

Common Complaints and Causes

In Dr. Dizon’s experience, local symptoms including vaginal dryness, pain with penetration, and vaginal thinning, are common sexual complaints in women with cancer, as are systemic issues such as lack of interest and menopause-type symptoms.

“For those undergoing radiation, the vaginal tunnel can actually develop adhesions, and if not treated proactively this can lead to vaginal stenosis,” said Dr. Dizon, who was not involved in the studies presented at the meeting.

Comorbidities such as diabetes, cardiovascular disease, and musculoskeletal conditions can contribute to sexual issues in women with cancer, according to Nora Lersch, DNP, FNP-BC, AOCNP, and Nicole Dreibelbis, CRNP, the authors of other research presented at the meeting.

Culture, religion, fitness level, history of sexual violence, and gender spectrum health also play a role, as do anxiety and depression, dementia, and substance abuse disorders, the authors wrote in their presentation, “Prioritizing Sexual Health in Gynecological Oncology Care.”

Low libido is a frequent complaint across all cancer types, Ms. Dreibelbis, a nurse practitioner specializing in gynecologic oncology at the UPMC Hillman Cancer Center, Pittsburgh, Pennsylvania, said in an interview.

“Breast cancer patients, especially those on [aromatase inhibitor] therapy, often experience vaginal dryness and therefore dyspareunia,” she added.

The pelvic floor muscles, with their important role in sexual response, can be weakened by cancer treatment or surgery, and the pudendal nerves, which are the primary nerves responsible for sexual response in women, can be affected as well, Dr. Lersch and Ms. Dreibelbis wrote.
 

Taking Sex Seriously

Researchers are exploring the impact of different cancer prevention treatments for women to mitigate sexual side effects, as illustrated by another study presented at the meeting.

Dr. Barbara Norquist, MD, a gynecologic oncologist at the University of Washington, Seattle, and colleagues compared the sexual function and menopausal symptoms of patients at high risk of ovarian carcinoma who underwent either interval salpingectomy/delayed oophorectomy (ISDO) or risk-reducing salpingo-oophorectomy (RRSO).

“For patients at high risk for ovarian cancer, surgical removal of the tubes and ovaries is the mainstay of prevention, as screening is not effective at reducing death from ovarian cancer. As a result of surgery, many patients become suddenly postmenopausal from losing their ovaries,” Dr. Norquist said in an interview.

Some patients delay surgery out of concern for health and quality of life, including sexual function, she said.

In the study (known as the WISP trial) the researchers compared data from 166 patients who underwent immediate removal of the fallopian tubes and ovaries and 171 who underwent fallopian tube removal and delayed oophorectomy. All patients completed questionnaires about sexual function. The primary outcome was change in sexual function based on the sexual function index (FSFI) from baseline to 6 months after surgery.

Overall, changes in sexual function were significantly greater in the immediate oophorectomy group, compared with the delayed oophorectomy group at 6 months (33% vs 17%) and also at 12 months (43% vs 20%).

A further review of patients using hormone therapy showed that those in the immediate oophorectomy group still had greater decreases in sexual function, compared with the delayed group, though the difference between groups of patients using hormone therapy was less dramatic.

“I was surprised that, even with hormone replacement therapy, patients undergoing removal of the ovaries still had significant detrimental changes to sexual function when compared to those having the tubes removed, although this was even worse in those who could not take HRT,” Dr. Norquist said, in an interview. “I was reassured that menopausal symptoms in general were well managed with HRT, as these patients did not score differently on menopause symptoms, compared with those having their tubes removed,” she said.

Patients deserve accurate information about predicted changes in menopausal symptoms and sexual function as a result of ovary removal, and HRT should be provided when there is no contraindication, Dr. Norquist told this news organization.

Dr. Norquist and colleagues are awaiting the results of clinical trials investigating the safety of salpingectomy with delayed oophorectomy in terms of ovarian cancer prevention, but more research is needed to identify optimal management of the menopausal and sexual side effects associated with surgical menopause, she noted.

“Findings from the WISP study show the importance of hormones in women undergoing prophylactic surgery,” Dr. Dizon said. The findings indicate that salpingectomy has less of a negative influence on sexual function compared to removal of the ovaries, and the impact of hormone therapy and the relatively young age of the patients who took hormones reinforces current knowledge about hormones and sex, he added.
 

Barriers and Solutions

Barriers to asking women with cancer about sexual issues reported by providers include limited time, lack of training in sexual health, a desire to avoid offending the patient or making them uncomfortable, and uncertainty about how to answer the questions, Dr. Lersch and Ms. Dreibelbis wrote in their presentation.

Barriers to asking healthcare providers about their sexual issues reported by patients include the beliefs that the clinician should initiate the discussion, that sexual function will not be taken seriously, and that they might make the provider uncomfortable.

“Fortunately, more information and research has been done on sexual health and gynecological cancer in recent years, so oncologists are becoming more aware of the issues women may have,” said Dr. Lersch who is an oncology nurse practitioner at Providence Franz Cancer Institute in Portland, Oregon, in an interview.

Telling patients early in their cancer treatment about potential sexual side effects and opportunities for help is essential, she added.

Although oncologists have become more aware of the importance of sexual health and well-being for their patients, “I think there has historically been a disconnect in including sexual health education in medical training,” Ms. Dreibelbis said in an interview.

Dr. Lersch and Ms. Dreibelbis advised a multidimensional approach to managing sexual problems in cancer patients that includes consideration of biological and psychological symptoms, but also social, cultural, and interpersonal factors, in their presentation.

Their suggestions include discussing dyspareunia with their patients, asking for details such as whether the pain is internal or external, whether it occurs with activities outside of sex including masturbation, and whether bleeding is present.

Oncology therapies and surgeries can decrease or eliminate an individual’s ability to produce their own lubricant; for example, removal of the cervix eliminates cervical mucous, which helps with internal lubrication, they wrote in their presentation.

For patients with dyspareunia, Dr. Lersch and Ms. Dreibelbis recommend a vaginal moisturizer especially formulated for vaginal tissue that can be absorbed by the mucosal tissue of the vagina. Use of this type of product can increase the effectiveness of lubricants and help restore integrity of the vaginal tissue. Such moisturizers are available as gels, creams, or suppositories over the counter, and do not contain hormones.

Vaginal estrogen can be helpful for burning, itching, irritation, tissue fragility, and pain with sex, according to Dr. Lersch and Ms. Dreibelbis. Adequate estrogen therapy can promote normalization of vaginal pH and microflora, as well increase vaginal secretion and reduce pain and dryness with intercourse, the presenters stated in their presentation. In addition, dilator therapy can be used to help prevent vaginal stenosis, and penetration bumpers can help relieve discomfort during intercourse, they wrote.

Looking ahead, more research is needed to serve a wider patient population, Ms. Dreibelbis said, in an interview.

“LGBTQIA [individuals] have not been included in sexual health research and there are more people than ever who identify within this group of people. I know there has also been some very early work on shielding the clitoris from the impacts of radiation, and I believe this is extremely important up-and-coming research,” she said.

Dr. Lersch, Ms. Dreibelbi, Dr. Dizon, Dr. Norquist, Ms. Brewer, and Dr. Mehta had no financial conflicts to disclose.

Is liquid biopsy helpful for monitoring the effectiveness of adjuvant therapy for patients with non–small cell lung cancer? It depends on whom you ask.

The clinical utility of circulating tumor DNA (ctDNA) for detecting minimal residual disease (MRD) and for treatment planning postoperatively was a topic of debate at the European Lung Cancer Congress 2024, held in Prague, Czech Republic.
 

PRO: Prognostic Value

Enriqueta Felip, MD, PhD, of Vall d’Hebron Institute of Oncology in Barcelona, Spain, argued in favor of using liquid biopsy for disease surveillance and decision making about adjuvant therapy.

“In early stage non–small cell lung cancer I think the evidence shows that pretreatment baseline ctDNA levels are clearly prognostic, and also, after surgical resection, the MRD predicts relapse, so we know that at present ctDNA and MRD are strong prognostic markers,” she said.

“I think ctDNA is useful as a noninvasive tool in both settings — at baseline pre surgery and also post surgery — to guide adjuvant therapy decision making,” she added.

Dr. Felip noted that so-called “tumor-informed” assays, such as sequencing of tumor tissue to identify mutations that can then be tracked in plasma samples, are high sensitivity methods, but have a long turnaround time, and approximately one in five patients does not have adequate tumor tissues for analysis.

In contrast, “tumor agnostic” methods rely on epigenetic features such as DNA methylation and cell-free DNA fragmentation patterns to detect tumor-derived DNA, but don’t rely on tumor tissue sample.

Dr. Felip cited a 2017 study published in Cancer Discovery showing that in patients with localized lung cancer post treatment ctDNA detection preceded radiographic progression in 72% of patients by a median of 5.2 months. In addition, the investigators found that 53% of patients had ctDNA mutation profiles that suggested they would respond favorably to tyrosine kinase inhibitors or immune checkpoint inhibitors.

She also pointed to 2022 European Society for Medical Oncology (ESMO) recommendations on the use of ctDNA in patients with cancer, which state that detection of residual tumor DNA after NSCLC therapy with curative intent is associated with a high risk of future relapse, as supported by evidence from multiple studies. The recommendation also states, however, that there is insufficient evidence to recommend ctDNA testing in routine clinical practice in the absence of evidence from prospective clinical trials.

Evidence to support a benefit of ctDNA detection for treatment planning in the adjuvant setting come from several clinical studies, Dr. Felip said. For example, in a 2020 study published in Nature Cancer, investigators found that patients with detectable ctDNA after chemoradiotherapy who had treatment consolidation with an immune checkpoint inhibitor had significantly better freedom from progression compared with patients who had detectable ctDNA but did not receive consolidation immunotherapy.

In the IMpower010 trial, patients who were ctDNA-positive post surgery and received adjuvant atezolizumab (Tecentriq) had a median disease-free survival of 19.1 months, compared with 7.9 months for patients who did not get the immune checkpoint inhibitor, further indicating the value of ctDNA in the adjuvant setting, she said.

Wrapping up her argument, Dr. Felip acknowledged that currently the negative predictive value of ctDNA/MRD is suboptimal.

“However, we have seen that high ctDNA levels pre surgery predict poor outcome, and MRD-positive following definitive therapy is strongly prognostic and has extremely high positive predictive value for recurrence,” she said.

Taken together, the evidence suggests that patients who are ctDNA-positive preoperatively should be considered for neoadjuvant chemotherapy and immune checkpoint inhibition. If ctDNA persists after neoadjuvant therapy, patients should have extensive re-staging before surgery, because their options for pathologic complete response are limited. Patients who are MRD-positive after surgery should be treated with the same therapeutic approach as for patients with metastatic disease, Dr. Felip concluded.
 

CON: No Data Supporting OS Benefit

Offering counterpoint to Dr. Felip’s argument, Jordi Remon Masip, MD, PhD, of Gustave Roussy cancer treatment center in Villejuif, France, said that the currently available evidence suggests that MRD helps identify a high-risk population, but that its utility in the clinic is still uncertain.

“Today, I am a believer that we need prospective clinical trials, but one of the most important points today is to elucidate if the minimal residual disease is just prognostic or whether we really can use this minimal residual disease for making treatment decisions, not only escalating [but] also de-escalating treatment strategies in early stage non–small cell lung cancer,” he said.

Risk stratification may help to identify those patients who can most benefit from intensive therapy, but it appears to be much more difficult to risk stratify patients with early stage NSCLC, he said, pointing to the International Tailored Chemotherapy Adjuvant (ITACA) trial, a phase III multicenter randomized trial comparing adjuvant pharmacogenomic-driven chemotherapy versus standard adjuvant chemotherapy in patients with completely resected stage II-IIIA NSCLC. In this study, chemotherapy customized to individual patients according to molecular diagnostic analysis after surgery did not improve overall survival outcomes.

Dr. Masip said that as a clinician he would like to have any reliable tool that could help him to decide which patients need more therapy and which can do well with less.

He agreed that MRD-positivity as signaled by ctDNA after surgery or by a tumor-informed method correlates with poor prognosis, but he noted that MRD status depends on clinical characteristics such as sex, smoking status, age, stage, tumor size, histology, and many other factors that need to be taken into account if the assay is to have value in clinical practice.

“It’s true that the minimal residual disease may capture a poor prognostic population. However, even if we apply the minimal residual disease in our daily clinical practice, we can only capture, or we can only rescue 20% of the patients with the wild type or oncogenic early stage non–small cell lung cancer,” he said.

In addition, as Dr. Felip acknowledged, the negative predictive value of MRD is not infallible, with a 63% false negative rate compared with only a 2% false-positive rate.

“Half of the patients with the recurrence of the disease have a very, very low circulating tumor DNA, and the techniques are not sensitive enough to capture this minimal residual disease,” Dr. Masip said.

It would also be a mistake to forgo giving adjuvant therapy to those patients deemed to be MRD-negative on the basis of ctDNA, given the high false-negative rates, he said.

Oncologists also have to put themselves in their patients’ shoes:

“If our patients accept that with minimal residual disease I can only improve the disease-free survival without improving the overall survival, they would accept having less toxicity but the same survival that they would if they started the treatment later, and also what would happen if the patient is randomized to no adjuvant treatment because the minimal residual disease is negative, and some months later there is a recurrence of disease?” Dr. Masip said.

“I think we need more prospective data, but we really, really need a more sensitive test to avoid or to decrease the percentage of patients with false-negative results, and also we need very motivated patients that would accept to be randomized to de-escalate treatment strategies,” he concluded.

Is liquid biopsy helpful for monitoring the effectiveness of adjuvant therapy for patients with non–small cell lung cancer? It depends on whom you ask.

The clinical utility of circulating tumor DNA (ctDNA) for detecting minimal residual disease (MRD) and for treatment planning postoperatively was a topic of debate at the European Lung Cancer Congress 2024, held in Prague, Czech Republic.
 

PRO: Prognostic Value

Enriqueta Felip, MD, PhD, of Vall d’Hebron Institute of Oncology in Barcelona, Spain, argued in favor of using liquid biopsy for disease surveillance and decision making about adjuvant therapy.

“In early stage non–small cell lung cancer I think the evidence shows that pretreatment baseline ctDNA levels are clearly prognostic, and also, after surgical resection, the MRD predicts relapse, so we know that at present ctDNA and MRD are strong prognostic markers,” she said.

“I think ctDNA is useful as a noninvasive tool in both settings — at baseline pre surgery and also post surgery — to guide adjuvant therapy decision making,” she added.

Dr. Felip noted that so-called “tumor-informed” assays, such as sequencing of tumor tissue to identify mutations that can then be tracked in plasma samples, are high sensitivity methods, but have a long turnaround time, and approximately one in five patients does not have adequate tumor tissues for analysis.

In contrast, “tumor agnostic” methods rely on epigenetic features such as DNA methylation and cell-free DNA fragmentation patterns to detect tumor-derived DNA, but don’t rely on tumor tissue sample.

Dr. Felip cited a 2017 study published in Cancer Discovery showing that in patients with localized lung cancer post treatment ctDNA detection preceded radiographic progression in 72% of patients by a median of 5.2 months. In addition, the investigators found that 53% of patients had ctDNA mutation profiles that suggested they would respond favorably to tyrosine kinase inhibitors or immune checkpoint inhibitors.

She also pointed to 2022 European Society for Medical Oncology (ESMO) recommendations on the use of ctDNA in patients with cancer, which state that detection of residual tumor DNA after NSCLC therapy with curative intent is associated with a high risk of future relapse, as supported by evidence from multiple studies. The recommendation also states, however, that there is insufficient evidence to recommend ctDNA testing in routine clinical practice in the absence of evidence from prospective clinical trials.

Evidence to support a benefit of ctDNA detection for treatment planning in the adjuvant setting come from several clinical studies, Dr. Felip said. For example, in a 2020 study published in Nature Cancer, investigators found that patients with detectable ctDNA after chemoradiotherapy who had treatment consolidation with an immune checkpoint inhibitor had significantly better freedom from progression compared with patients who had detectable ctDNA but did not receive consolidation immunotherapy.

In the IMpower010 trial, patients who were ctDNA-positive post surgery and received adjuvant atezolizumab (Tecentriq) had a median disease-free survival of 19.1 months, compared with 7.9 months for patients who did not get the immune checkpoint inhibitor, further indicating the value of ctDNA in the adjuvant setting, she said.

A recent analysis identified significant disparities in survival outcomes as well as clinical and genetic features between Black and White women with a common subtype of endometrial cancer.

In addition to observing differences in clinical and molecular characteristics, the analysis of real-world registries and clinical trials revealed that Black patients with endometrioid endometrial carcinoma had about a twofold higher risk for cancer-related deaths than White patients.

“Even with propensity-score matching, Black patients had a significantly increased risk of death,” Zachary Kopelman, DO, with Walter Reed National Military Medical Center, Bethesda, Maryland, noted in a presentation at the Society of Gynecologic Oncology’s Annual Meeting on Women’s Cancer.

Importantly, Dr. Kopelman added, the analysis also confirmed “dramatic” underrepresentation of Black patients with endometrioid endometrial carcinoma in clinical trials.

Endometrial cancer is one of the most common cancers among women in the United States, with data showing rising incidence and mortality rates. “Worryingly, endometrial cancer is estimated to overtake ovarian cancer as the deadliest gynecologic malignancy this year,” Dr. Kopelman told attendees.

Previous studies have shown that Black patients with endometrial cancer consistently are more likely to have aggressive histologic subtypes, high-grade tumors, and advanced-stage disease and are twice as likely to die from the disease as White patients, he noted.

Within endometrial cancer, the most common histologic subtype is endometrioid, comprising 65%-75% of cases. In other studies examining racial disparities, the endometrioid histology is often combined with other subtypes, such as aggressive uterine serous carcinoma, which may influence study outcomes, Dr. Kopelman explained.

Dr. Kopelman and colleagues focused their analyses on Black and White women with endometrioid endometrial carcinoma, with the goal of identifying disparities in cancer-related and non-cancer deaths, as well as clinical and molecular features in this patient population.

All women included in the analysis had undergone hysterectomy with or without adjuvant treatment. The researchers used a four-pronged approach incorporating data from the SEER program (2004-2016), the National Cancer Database (2004-2017), eight National Cancer Institute-sponsored randomized phase 3 clinical trials, and the Genomics Evidence Neoplasia Information Exchange project.

Dr. Kopelman and colleagues then performed propensity score matching in the National Cancer Database and exact matching in the randomized controlled trials.

When comparing 47,959 White patients with 4397 Black patients in the SEER dataset, Dr. Kopelman and colleagues found that Black patients had more than two times the risk of dying from their cancer (hazard ratio [HR], 2.04) and a 22% greater risk for a non-cancer death compared with White patients (HR, 1.22).

In the overall National Cancer Database cohort comparing 155,706 White and 13,468 Black patients, Black patients had a 52% greater risk of dying from any cause (HR, 1.52). In the propensity score-matched cohort of 13,468 White and 13,468 Black patients, survival among Black patients remained significantly worse, with a 29% greater risk of dying from any cause (HR, 1.29).

When looking at clinical trial data, Black patients were more likely than White patients to have worse performance status and a higher grade or recurrent disease, Dr. Kopelman noted.

Black patients in the clinical trials also had significantly worse progression-free survival in both the original cohort (HR, 2.05) and the matched cohort (adjusted HR [aHR], 1.22), which matched patients for grade, stage, and treatment arm within each trial and balanced age and performance status. Black patients also had worse overall survival in the original cohort (HR, 2.19) and matched cohort (aHR, 1.32).

Looking at molecular features, Black patients had significantly fewer mutations in a handful of cancer-related gene pathways, including PTEN, PIK3R1, FBXW7, NF1, mTOR, CCND1, and PI3K pathways.

One caveat, said Dr. Kopelman, is that mutations in PTEN are still present in a high percentage of both Black (62%) and White (72%), which «offers a potential attractive therapeutic opportunity.»

The analysis also revealed a major gap in the number of Black vs White patients enrolled in randomized clinical trials, which is a major “problem,” said Dr. Kopelman.

The study confirms “ongoing disparities in enrollment and underrepresentation of minorities in gynecologic cancer clinical trials, as well as poor outcomes, and should really promote us to enhance research in these areas,” said study discussant Mariam AlHilli, MD, with Cleveland Clinic Lerner College of Medicine and Case Western Reserve University, Cleveland, Ohio.

David M. O’Malley, MD, who gave a separate talk during the same session on practical considerations for implication of clinical trials, encouraged clinicians to “just ask.”

“Just ask the patient in front of you — no matter what their ethnicity, their race, or where they’re coming from — are they interested in participating in a clinical trial?” Or better yet, “I have a clinical trial now which I’m excited about for you,” said Dr. O’Malley, with The Ohio State University, James Comprehensive Cancer Center, Columbus, Ohio.The study had no commercial funding. Dr. Kopelman, Dr. O’Malley, and Dr. AlHilli had no relevant disclosures.

The study confirms “ongoing disparities in enrollment and underrepresentation of minorities in gynecologic cancer clinical trials, as well as poor outcomes, and should really promote us to enhance research in these areas,” said study discussant Mariam AlHilli, MD, with Cleveland Clinic Lerner College of Medicine and Case Western Reserve University, Cleveland, Ohio.

David M. O’Malley, MD, who gave a separate talk during the same session on practical considerations for implication of clinical trials, encouraged clinicians to “just ask.”

“Just ask the patient in front of you — no matter what their ethnicity, their race, or where they’re coming from — are they interested in participating in a clinical trial?” Or better yet, “I have a clinical trial now which I’m excited about for you,” said Dr. O’Malley, with The Ohio State University, James Comprehensive Cancer Center, Columbus, Ohio.The study had no commercial funding. Dr. Kopelman, Dr. O’Malley, and Dr. AlHilli had no relevant disclosures.

Black people, men, older adults, and those living in rural communities are less likely to receive thrombolytic therapy after ischemic stroke, early research shows.

“The findings should serve as an eye-opener that social determinants of health seem to be playing a role in who receives thrombolytic therapy, said study investigator Chanaka Kahathuduwa, MD, PhD, resident physician, Department of Neurology, School of Medicine, Texas Tech University Health Sciences Center, Lubbock. 

The findings were released ahead of the study’s scheduled presentation at the annual meeting of the American Academy of Neurology.
 

Contributor to Poor Outcomes

Social determinants of health are important contributors to poor stroke-related outcomes, the investigators noted. They pointed out that previous research has yielded conflicting results as to the cause.

Whereas some studies suggest poor social determinants of health drive increased stroke incidence, others raise the question of whether there are disparities in acute stroke care. 

To investigate, the researchers used a publicly available database and diagnostic and procedure codes to identify patients presenting at emergency departments in Texas from 2016 to 2019 with ischemic stroke who did and did not receive thrombolytic therapy.

“We focused on Texas, which has a very large area but few places where people have easy access to health care, which is a problem,” said study co-investigator Chathurika Dhanasekara, MD, PhD, research assistant professor in the Department of Surgery, School of Medicine, Texas Tech University Health Sciences Center.

The study included 63,983 stroke patients, of whom 51.6% were female, 66.6% were White, and 17.7% were Black. Of these, 7198 (11.2%) received thrombolytic therapy; such therapies include the tissue plasminogen activators (tPAs) alteplase and tenecteplace.

Researchers collected information on social determinants of health such as age, race, gender, insurance type, and residence based on zip codes. They computed risk ratios (RRs) of administering thrombolysis on the basis of these variables.

Results showed that Black patients were less likely than their White counterparts to receive thrombolysis (RR, 0.90; 95% CI, 0.85-0.96). In addition, patients older than 65 years were less likely those aged 18-45 years to receive thrombolysis (RR, 0.47; 95% CI, 0.44-0.51), and rural residents were less likely than urban dwellers to receive the intervention (RR, 0.60; 95% CI, 0.55-0.65).

It makes some sense, the researchers said, that rural stroke patients would be less likely to get thrombolysis because there’s a limited time window — within 4.5 hours — during which this therapy can be given, and such patients may live a long distance from a hospital.

Two other groups less likely to receive thrombolysis were Hispanic persons versus non-Hispanic persons (RR, 0.93; 95% CI, 0.87-0.98) and Medicare/Medicaid/Veterans Administration patients (RR, 0.77; 95% CI, 0.73-0.81) or uninsured patients (RR, 0.90; 95% CI, 0.94-0.87) vs those with private insurance.

Interestingly, male patients were less likely than female patients to receive thrombolysis (RR, 0.95; 95% CI, 0.90-0.99).
 

Surprising Findings

With the exception of the discrepancy in thrombolysis rates between rural versus urban dwellers, the study’s findings were surprising, said Dr. Kahathuduwa. 

Researchers divided participants into quartiles, from least to most disadvantaged, based on the Social Vulnerability Index (SVI), created by the Centers for Disease Control and Prevention to determine social vulnerability or factors that can negatively affect a community’s health. 

Among the 7930 individuals in the least disadvantaged group, 1037 received thrombolysis. In comparison, among the 7966 persons in the most disadvantaged group, 964 received thrombolysis.

After adjusting for age, sex, and education, investigators found that patients in the first quartile based on SVI were more likely to be associated with thrombolysis vs those in the second and third quartiles (RR, 1.13; 95% CI, 1.04-1.22).

The researchers also examined the impact of comorbidities using the Charlson Comorbidity Index. Patients with diabetes, hypertension, and high cholesterol in addition to signs of stroke would rouse a higher degree of suspicion and be more likely to be treated with tPA or tenecteplase, said Dr. Kahathuduwa.

“But even when we controlled for those comorbidities, the relationships we identified between health disparities and the likelihood of receiving thrombolysis remained the same,” said Dr. Kahathuduwa.

It’s not clear from this study what factors contribute to the disparities in stroke treatment. “All we know is these relationships exist,” said Dr. Kahathuduwa. “We should use this as a foundation to understand what’s really going on at the grassroots level.”

However, he added, it’s possible that accessibility plays a role. He noted that Lubbock has the only Level 1 stroke center in west Texas; most stroke centers in the state are concentrated in cities in east and central Texas.

The investigators are embarking on further research to assess the impact of determinants of health on receipt of endovascular therapy and the role of stroke severity.

“In an ideal world, all patients who need thrombolytic therapy would get thrombolytic therapy within the recommended time window because the benefits are very clear,” said Dr. Kahathuduwa.

The findings may not be generalizable because they come from a single database. “Our findings need to be validated in another independent dataset before we can confidently determine what’s going on,” said Dr. Kahathuduwa.

A limitation of the study was that it is unknown how many of the participants were seen at the hospital within the recommended time frame and would thus be eligible to receive the treatment.

Commenting on the research, Martinson Arnan, MD , a vascular neurologist at Bronson Neuroscience Center, Kalamazoo, Michigan, said the study’s “exploratory finding” is important and “illuminates the potential impact of social determinants of health on disparities in acute stroke treatment.”

Neurologists consistently emphasize the principle that “time is brain” — that timely restoration of blood flow is crucial for minimizing morbidity associated with ischemic stroke. This study offers a potential opportunity to investigate how social determinants of health may affect stroke care, said Dr. Arnan.

However, he added, further research is needed “to understand whether the differences in outcomes observed here are influenced by levels of health education, concordance between patients and their treating providers, or other issues related to access barriers.” 

The investigators and Dr. Arnan report no relevant conflicts of interest.

Breastfeeding by women with multiple sclerosis (MS) or neuromyelitis optica spectrum disorder (NMOSD) who are taking monoclonal antibodies (mAbs) appears to be safe for infants, new research confirmed.

Registry data showed no differences in health or development in the first 3 years of life among infants exposed to natalizumab, ocrelizumab, rituximab, or ofatumumab, compared with unexposed infants.

“Most monoclonal antibody medications for multiple sclerosis are not currently approved for use while a mother is breastfeeding,” even though the disease can develop during a person’s reproductive years, study investigator Kerstin Hellwig, MD, with Ruhr University in Bochum, Germany, said in a news release.

“Our data show infants exposed to these medications through breastfeeding experienced no negative effects on health or development within the first 3 years of life,” Dr. Hellwig said.

The findings were released ahead of the study’s scheduled presentation at the annual meeting of the American Academy of Neurology.
 

Registry Data and Analysis

Using the German MS and Pregnancy Registry, researchers identified 183 infants born to mothers taking mAbs while breastfeeding — 180 with a diagnosis of MS and three with a diagnosis of NMOSD. The infants were matched to 183 unexposed infants (control group).

Exposure to mAbs during lactation started a median of 19 days postpartum and lasted for a median of 172 days. The most commonly used mAb during lactation was natalizumab (125 women), followed by ocrelizumab (34 women), rituximab (11 women), and ofatumumab (10 women).

Among the entire infant cohort, two were first exposed to natalizumab and then ocrelizumab; one was exposed to rituximab and then ocrelizumab; three had been previously breastfed on glatiramer acetate and two on interferons.

The primary outcomes were hospitalizations, antibiotic use, developmental delay, and weight during the first 3 years of life in mAb-exposed versus unexposed infants.

In adjusted regression analyses, mAb exposure during breastfeeding was not significantly associated with annual hospitalization (rate ratio [RR], 1.23; P = .473), annual systemic antibiotic use (RR, 1.55; P = .093), developmental delay (odds ratio, 1.16; P = .716), or weight.

A limitation of the study was that only about a third of the infants were followed for the full 3 years. Therefore, Dr. Hellwig said, the results for the third year of life are less meaningful than for years 1 and 2.
 

‘Reassuring’ Data

Reached for comment, Edith L. Graham, MD, Department of Neurology, Multiple Sclerosis and Neuroimmunology, Northwestern University, Chicago, Illinois, noted that this is the largest group of breastfed infants exposed to mAbs used to treat MS and said the data provide “reassuring infant outcomes with no increase in hospitalization, antibiotic use, or developmental delay.”

Dr. Graham noted that recent publications have reported more on the use of anti-CD20 mAbs (ocrelizumab/rituximab/ofatumumab) while breastfeeding, “and this study adds data for patients on natalizumab.”

“It will be important to know how infusion timing after birth impacts transfer of monoclonal antibodies depending on the milk stage as it transitions from colostrum to mature milk in the first month postpartum,” Dr. Graham said.

“While infection rates of infants are reassuring, data on allergies in the exposed infants would be interesting to look at as well,” she added. “While these infusions are not orally bioavailable, we do not know the full extent of impact on the neonatal gut microbiome.”

In addition, Dr. Graham said it would be important to know whether drugs administered monthly, such as natalizumab and ofatumumab, accumulate in the breast milk at higher levels than medications such as ocrelizumab and rituximab, which are administered twice a year.

The German MS and pregnancy registry was partly supported by the Innovation Fund of the Federal Joint Committee, Almirall Hermal GmbH, Biogen GmbH Germany, Hexal AG, Merck Serono GmbH, Novartis Pharma GmbH, Roche Deutschland GmbH, Sanofi Genzyme, and Teva GmbH. Dr. Hellwig and Dr. Graham had no relevant disclosures.

Savolitinib, a selective oral tyrosine kinase inhibitor, showed good activity against locally advanced or metastatic non–small cell lung cancer (NSCLC) bearing MET exon 14 mutations as both first-line therapy for treatment-naive patients and in second-line of therapy for previously treated patients

“The phase 3b study results further confirm savolitinib as a valuable targeted therapy option for naive and previously-treated non–small cell lung cancer with MET 14 exon mutations,” Yongchang Zhang, MD, said while presenting the final results of the trial at the European Lung Cancer Congress 2024.

For 87 previously untreated patients the objective response rate (ORR) as assessed by independent review, the primary endpoint, was 62.1%. For 79 patients receiving savolitinib in the second line, the ORR was 39.2%, reported Dr. Zhang, MD, of the Hunan Cancer Hospital in Changsha, China.

Preliminary results of this trial were reported at the World Conference on Lung Cancer in 2023.

Selective Inhibitor

Savolitinib (AZD6094, also called volitinib) is reported to be a highly selective oral inhibitor of the MET receptor tyrosine kinase (TKI). It is approved in China for the treatment of patients with NSCLC harboring MET exon 14 mutations that has progressed on prior systemic therapy, or patients who are unable to tolerate platinum-based chemotherapy.

In the phase 3b study, patients with MET ex14-positive tumors who were negative for EGFR, ALK or ROS1 alterations and were naive to a MET inhibitor were enrolled. Those who weighed 50 kg or greater received 600 mg savolitinib orally once daily for each 21-day cycle, while patients who weighed less than 50 kg received a 400-mg daily dose. Therapy continued until disease progression, death, or unacceptable toxicity.

Tumors were evaluated by investigators every 6 weeks for the first year, than every 12 weeks thereafter.

As noted before, ORR by independent review was 62.1% for treatment-naive patients and 39.2% for previously treated patients. The respective ORRs by investigator assessment were 59.8% and 43%. All responses in each arm were partial responses.

Median progression-free survival (PFS) after a median follow-up of 18 months for treatment-naive patients and 11 months for treatment-experienced patients was 13.7 months and 11 months, respectively.

Overall survival after a median follow-up of 20.8 months for treatment-naive patients and 12.5 months for previously treated patients was not reached in treatment-naive patients and not mature in treatment-experienced patients.

Grade 3 or greater treatment-emergent adverse events occurred in 74.1% of patients, including 3 events (1.8%) leading to death. Dose modifications were required for 74.7% of patients.

Grade 3 or greater adverse events included peripheral edema, liver enzyme elevations, abnormal liver function, decreased platelet and white blood cell counts, and vomiting.
 

Which TKI is Best?

Invited discussant Antonio Passaro, MD, PhD, from the European Institute of Oncology in Milan, noted that eligibility for treatment with savolitinib or other MET exon 14-targeting TKIs is limited to about 3% of patients with NSCLC of adenocarcinoma histology.

He said that savolitinib appears to be similar in performance to two other TKIs for NSCLC with MET exon-14 skipping mutations that are currently on the market in the United States, Europe, and Japan: capmatinib (Tabrecta) and tepotinib (Tepmetko).

“Globally, all the results show a numerically better performance when we use a selective TKI in first-line treatment over the second-line treatment, in particular for overall response rate,” he said.

Dr. Passaro noted that savolitinib differs from the other two MET TKIs in that PFS with savolitinib is similar for treatment-naive and previously treated patients.

He added, however, that “today it’s very difficult” to determine which is the “perfect” agent for a specific disease presentation, particularly since MET exon 14 skipping mutations can also be found in patients with squamous cell carcinomas and those with a history of smoking.

To get a better sense of which drug to use in a specific situation, it would be helpful to analyze trial results in the context of tumor histology, smoking history, programmed death protein 1-ligand 1 status, and co-mutations, he said.

The study was sponsored by Hutchmed. Dr. Zhang reported having no conflicts of interest. Dr. Passaro reported a consulting, advisory, or speakers bureau role for multiple companies, not including Hutchmed.

Sodium-glucose cotransporter-2 (SGLT2) inhibitors and glucagon-like peptide 1 receptor agonists (GLP-1 RAs) are often not prescribed or accessible to people who could benefit from them, a trio of new studies suggested.

First approved for the treatment of type 2 diabetes, the indications for SGLT2 inhibitors and GLP-1 RA medications have now been extended to people with obesity, heart failure, and chronic kidney disease.

The papers were presented at the American Heart Association (AHA) Epidemiology and Prevention | Lifestyle and Cardiometabolic Scientific Sessions 2024.

The new data show there is “work to be done in terms of access and equity to these treatments,” Robert H. Eckel, MD, who was not involved in the research, said in a conference statement.

“There is no question that the cost of these medications is high, yet when issues go beyond coverage and include sociodemographic and racial differences that influence treatment, these major issues need to be evaluated and addressed,” said Dr. Eckel, professor emeritus of medicine, Division of Endocrinology, Metabolism, and Diabetes, University of Colorado Anschutz Medical Campus, Denver, and a past president of the AHA.
 

Low Prescription Rates

In one study, researchers analyzed health records for 18,164 adults with obesity (mean age, 51 years; 64% women; mean body mass index [BMI], 36 kg/m2) who had health insurance covering semaglutide and liraglutide (GLP-1 RAs) and tirzepatide (GLP-1/glucose-dependent insulinotropic polypeptide RA). The cohort was 54% White, 35% Black, and 5% Asian.

Only about 3% of eligible adults were prescribed one of these medications, reported Meron Haile, BS, a second-year medical student at Johns Hopkins University School of Medicine in Baltimore, and colleagues.

The likelihood of prescription was lower among Black patients (odds ratio [OR], 0.76) and men (OR, 0.54) and higher in people with higher BMI (OR, 1.06 per 1-unit higher BMI).

Living in a neighborhood with a higher area deprivation index or lower income was not independently associated with the likelihood of prescription.

Individuals with diabetes or hypertension were more likely to be prescribed one of these medications (OR, 3.52 and 1.36, respectively).

“While prescription rates for new obesity therapies are low among the overall population, we saw pronounced lower accessibility among Black adults, who exhibit a higher burden of severe obesity, hypertension, and type 2 diabetes,” Haile said in a conference statement.

“There is a crucial need for understanding prescription practices for obesity medications and to facilitate similar access among people in all races and ethnic groups,” Haile added.

Similar findings emerged in a separate study, in which researchers analyzed the health records of 687,165 adults with type 2 diabetes treated at six large health systems from 2014 to 2022.

The rate of annual pharmacy dispensing of SGLT2 inhibitors and GLP-1 RA medications rose during the study period, but there were clear racial and ethnic differences in prescribing.

In fully adjusted models, SGLT2 inhibitors dispensing was lower for American Indian/Alaska Native (AI/AN; OR, 0.80), Black (OR, 0.89), and Hispanic (OR, 0.87) individuals than for White patients.

Likewise, GLP-1 RA dispensing was also lower for AI/AN (OR, 0.78), Asian (OR, 0.50), Black (OR, 0.86), Hawaiian/Pacific Islander (OR, 0.52), and Hispanic (OR, 0.69) patients than for White patients.

“It’s possible that not all patients have equal access to information about these medications or that not all patients are equally comfortable asking their doctors about them,” lead author Luis A. Rodriguez, PhD, research scientist at Kaiser Permanente’s Northern California Division of Research, Oakland, told this news organization.

“We also don’t know if the cost of the new medications contributed to what we found or if some patients prefer to keep taking a pill rather than switch to some of the GLP-1 receptor agonists that are self-injectable medications. We need to learn more about why this is happening,” Dr. Rodriguez said.
 

‘Concerning’ Data Raise Key Questions

The third study explored how often prescribing recommendations for SGLT2 inhibitors are followed.

“Our study revealed a significant gap between the recommendations for prescribing SGLT2 inhibitors and the actual prescription rates among patients who could benefit from them,” Jung-Im Shin, MD, PhD, with the Welch Center for Prevention, Epidemiology, and Clinical Research, Johns Hopkins University, Baltimore, told this news organization.

“This could have important implications for patient care and outcomes, as SGLT2 inhibitors have been shown to be effective for heart and kidney protection in people with high-risk type 2 diabetes, chronic kidney disease, or heart failure,” Dr. Shin said.

Dr. Shin and colleagues analyzed the health records for more than 700,000 adults with type 2 diabetes and 2.5 million people without type 2 diabetes, who received care in 28 US health systems from 2022 to 2023.

Among people with type 2 diabetes recommended for first-line SGLT2 inhibitors treatment, only 12% received a prescription for a SGLT2 inhibitor, and there was no significant difference in prescription between people who met the criteria for first-line SGLT2 inhibitors treatment vs people who did not meet the criteria.

Among people without type 2 diabetes, SGLT2 inhibitor prescription was substantially lower, with only about 3% of people with conditions that are guideline-recommended for SGLT2 inhibitors receiving a prescription.

SGLT2 inhibitor prescription rates varied across health systems; however, less than 30% of people who met guideline criteria received a SGLT2 inhibitors prescription across all health systems in the study.

“Barriers to SGLT2 inhibitor prescription include limited insurance coverage, prohibitive out-of-pocket costs, formulary restrictions, and lack of physicians’ awareness or familiarity regarding benefits and appropriate indications for SGLT2 inhibitors,” Dr. Shin said.

“Efforts to improve access and affordability of SGLT2 inhibitors along with strategies to educate both patients and providers on the updated guidelines for SGLT2 inhibitors use may increase adoption,” Dr. Shin added.

In a conference recording, Dr. Eckel said he found it “particularly concerning” that among patients with insurance to help pay for these medications, “there were still discrepancies” between prescriptions to Asian and Black vs White patients, “who are being prescribed these important medications.”

“Why these medications are not being offered more regularly by healthcare providers” needs to be addressed, Dr. Eckel said. “I think part of it is ignorance and inadequate education as to their new indications for treatment of diseases that go beyond type 2 diabetes,” he noted.

None of the studies had commercial funding. The authors had no relevant disclosures.

Symptoms of sleep apnea, including snorting, gasping, or paused breathing during sleep, are associated with a significantly greater risk for problems with cognitive and memory problems, results from a large study showed.

Data from a representative sample of US adults show that those who reported sleep apnea symptoms were about 50% more likely to also report cognitive issues versus their counterparts without such symptoms.

“For clinicians, these findings suggest a potential benefit of considering sleep apnea as a possible contributing or exacerbating factor in individuals experiencing memory or cognitive problems. This could prompt further evaluation for sleep apnea, particularly in at-risk individuals,” said study investigator Dominique Low, MD, MPH, Department of Neurology, Boston Medical Center.

The findings were released ahead of the study’s scheduled presentation at the annual meeting of the American Academy of Neurology.

The findings are based on 4257 adults who participated in the 2017-2018 National Health and Nutrition Examination Survey and completed questionnaires covering sleep, memory, cognition, and decision-making abilities.

Those who reported snorting, gasping, or breathing pauses during sleep were categorized as experiencing sleep apnea symptoms. Those who reported memory trouble, periods of confusion, difficulty concentrating, or decision-making problems were classified as having memory or cognitive symptoms.

Overall, 1079 participants reported symptoms of sleep apnea. Compared with people without sleep apnea, those with symptoms were more likely to have cognitive problems (33% vs 20%) and have greater odds of having memory or cognitive symptoms, even after adjusting for age, gender, race, and education (adjusted odds ratio, 2.02; P < .001).

“While the study did not establish a cause-and-effect relationship, the findings suggest the importance of raising awareness about the potential link between sleep and cognitive function. Early identification and treatment may improve overall health and potentially lead to a better quality of life,” Dr. Low said.

Limitations of the study include self-reported data on sleep apnea symptoms and cognitive issues sourced from one survey.
 

Consistent Data

Reached for comment, Matthew Pase, PhD, with the Turner Institute for Brain and Mental Health, Monash University, Melbourne, Australia, said the results are similar to earlier work that found a link between obstructive sleep apnea and cognition.

For example, in a recent study, the presence of mild to severe OSA, identified using overnight polysomnography in five community-based cohorts with more than 5900 adults, was associated with poorer cognitive test performance, Dr. Pase said.

“These and other results underscore the importance of healthy sleep for optimal brain health. Future research is needed to test if treating OSA and other sleep disorders can reduce the risk of cognitive impairment,” Dr. Pase said.

Yet, in its latest statement on the topic, the US Preventive Services Task Force concluded there remains insufficient evidence to weigh the balance of benefits and harms of screening for OSA among asymptomatic adults and those with unrecognized symptoms.

The study had no specific funding. Dr. Low and Dr. Pase had no relevant disclosures.

Symptoms of sleep apnea, including snorting, gasping, or paused breathing during sleep, are associated with a significantly greater risk for problems with cognitive and memory problems, results from a large study showed.

Data from a representative sample of US adults show that those who reported sleep apnea symptoms were about 50% more likely to also report cognitive issues versus their counterparts without such symptoms.

“For clinicians, these findings suggest a potential benefit of considering sleep apnea as a possible contributing or exacerbating factor in individuals experiencing memory or cognitive problems. This could prompt further evaluation for sleep apnea, particularly in at-risk individuals,” said study investigator Dominique Low, MD, MPH, Department of Neurology, Boston Medical Center.

The findings were released ahead of the study’s scheduled presentation at the annual meeting of the American Academy of Neurology.

Minimally invasive cytoreductive surgery for epithelial ovarian cancer appears to be safe and does not compromise survival, compared with open surgery, when patients have completely resected tumors.

This was a finding of a retrospective study presented by Judy Hayek, MD, during an oral abstract session at the Society of Gynecologic Oncology’s Annual Meeting on Women’s Cancer, in San Diego.

Among 2,412 women in the National Cancer Database with tumor-free surgical margins (R0 resections) after interval debulking surgery (IDS), the median overall survival (OS) was 46 months for those who had undergone an open procedure or minimally invasive surgery (MIS) that was converted to an open procedure. In contrast, the median OS was 51 months for patients who underwent laparoscopic or robot-assisted minimally invasive surgery, reported Dr. Hayek, a gynecologic oncology fellow at SUNY Downstate Health Sciences University in Brooklyn, New York.

“R0 resection at the time of interval debulking surgery has similar survival outcomes by minimally invasive surgery versus laparotomy, while R0 resection via laparotomy is associated with higher perioperative mortality. There is no interaction between the extent of surgery and the impact of MIS on survival,” she said during her presentation.

The session included a debate on the pros and cons of minimally invasive vs. open surgery in this population.
 

Growing Use of MIS

Over the last decade, minimally invasive surgery for interval debulking was shown to be safe and feasible. More recently, two studies using National Cancer Database cohorts showed that survival was similar and perioperative outcomes were better with a minimally invasive approach at the time of IDS for patients with early disease, Dr. Hayek said (Obstet Gynecol 2017 Jul;130(1):71-79; and Gynecol Oncol 2023 May:172:130-137).

Potential limitations of MIS include the absence of haptic feedback compared with open surgery, and the possibility that limited visualization of the surgical field could lead to missed residual disease and subsequent poor outcomes for patients who were presumed to have complete gross resections, she said.
 

Outcomes Compared

Dr. Hayek and colleagues conducted their study to evaluate survival outcomes after R0 resections by MIS or laparotomy in IDS for patients with advanced epithelial ovarian cancer.

As noted before, they looked at outcomes for 2,412 women with stage IIIC or IV cancers of all histology types who were diagnosed from 2010 through 2019. A total of 624 patients (25.9%) had minimally invasive procedures, and 1,788 (74.1%) had open surgery or MIS that had been converted to open procedures.

Of the minimally invasive procedures, 48.7% were robot-assisted, and the remainder were laparoscopic.

Over the decade of the study, the frequency of minimally invasive surgery steadily increased, from 11.9% of all procedures in 2010 to 36.5% in 2019.

Also as noted, there was no difference in median overall survival, at 46 months for open/converted procedures vs. 51 months for minimally invasive procedures.

As might be expected, the mean length of stay was shorter with the less invasive surgery: 3.3 days compared with 5.3 days with open surgery (P less than .001). In addition, 30-day and 90-day mortality rates were also lower with MIS, at 0.8% and 1.9%, respectively, compared with 1.6% and 3.5% with laparotomy (P = .006 for 30-day mortality, and .003 for 90-day).

There were also no differences in overall survival between the procedure types when the cases were stratified according to extent of surgery. Within the minimally invasive surgery groups there were no differences in median OS for patients whose surgery was performed laparoscopically or with robotic assistance.

The study was limited by a lack of data on either patient-specific tumor burden, neoadjuvant chemotherapy use, progression-free survival, cause of death, or surgical morbidity, Dr. Hayek acknowledged.
 

MIS Use Debatable: CON

Despite the good outcomes with minimally invasive techniques in this favorable-risk population, critics contend that MIS interval cytoreduction is too risky in the majority of cases.

In the debate portion of the session, Kara Long Roche, MD, an associate attending in the section of ovarian cancer surgery at Memorial Sloan Kettering Cancer Center in New York, argued that the potential for MIS missing residual disease is too great.

“We know from almost every retrospective and prospective study done that the volume of residual disease after debulking, whether primary or interval, is the most important prognostic factor for our patients that we can modify,” she said.

Rather than debating morbidity, mortality, or criteria for resection, “I would argue that the question we need to debate is can MIS interval debulking achieve a completeness of resection, i.e., volume of residual disease?” she said.

Dr. Roche contended that retrospective studies such as that reported by Dr. Hayek cannot adequately answer this question because of selection bias. Patients selected for MIS have better responses to neoadjuvant chemotherapy and more favorable tumor biology; and, therefore, overall survival may not be the optimal endpoint for retrospective studies.

In addition, neoadjuvant chemotherapy does not automatically preclude the need for extensive upper abdominal surgery since almost half of patients who receive neoadjuvant chemotherapy are found to have bulky upper abdominal disease at the time of debulking.

Dr. Roche especially cautioned against what she called the WNL or “We Never Looked” phenomenon, in which patients are found on open surgery and organ mobilization to have disease that was not evident on presurgical imaging.

She acknowledged that for some patients the risks of laparotomy are likely to outweigh the benefit of a radical resection, and stressed that for such patients forgoing surgery or optimizing perioperative care may be more important than the size of the incision.

MIS IDS should be the exception, not the rule. We need prospective data with appropriate endpoints. We need surgical quality control in both arms, and we need to continue to focus on surgical education and training so that our trainees can graduate doing these procedures via any approach,” she concluded.
 

Debate: PRO

Arguing in favor of MIS for ovarian cancer, J. Alejandro Rauh-Hain, MD, MPH, associate professor of gynecologic oncology at the University of Texas MD Anderson Cancer Center in Houston, told attendees “the only bias I have is that I actually love doing open surgery, but I’m going to try to convince you that there is a potential role for minimally invasive surgery in the future for selected patients with ovarian cancer after neoadjuvant chemotherapy.”

He noted that several studies have convincingly shown that neoadjuvant chemotherapy does not adversely affect oncologic outcomes for patients with advanced-stage ovarian cancer, and decreases perioperative morbidity in patients who receive it, including reductions in serious adverse events, risk of stoma, and 30-day postoperative mortality.

In addition, low use of neoadjuvant chemotherapy is associated with increased risks for 90-day postoperative deaths in both low- and high surgical volume centers in the US, according to unpublished National Cancer Database data.

Dr. Rauh-Hain noted that neoadjuvant chemotherapy use has steadily increased from 2010 through 2020, and added that in 2022, 32% of interval cytoreductive surgeries in the United States were performed with a minimally invasive approach.

To get a better handle on the MIS vs. open-surgery question, Dr. Rauh-Hain and colleagues at MD Anderson and 13 other centers in the United States, Canada, and Europe are currently recruiting patients for the Laparoscopic Cytoreduction After Neoadjuvant Chemotherapy (LANCE) trial. In this phase 3 noninferiority study, patients with stage IIIC-IV ovarian, primary peritoneal, or fallopian tube cancer who have complete or partial responses and CA125 normalization after three or four cycles of neoadjuvant chemotherapy will be randomized to laparotomy or MIS, followed by adjuvant platinum- and taxane-based chemotherapy.

The study by Hayek et al. was internally supported. Dr. Hayek and Dr. Roche reported having no conflicts of interest. Dr. Rauh-Hain disclosed financial relationships with Guidepoint Consulting, and the Schlesinger Group.

In the not-too-distant future, immunotherapy might be administered to cancer patients in their homes.

The possibility is being driven by the development of subcutaneous formulations of commonly used immune checkpoint inhibitors for non–small cell lung cancer (NSCLC) and other indications, including pembrolizumab, nivolumab, durvalumab, atezolizumab, and amivantamab.

Instead of waiting anywhere from 30 minutes to several hours for infusions into their veins, patients would spend just a few minutes being injected under the loose skin of their abdomens or thighs. Clinicians would save time and money, and patients would leave the clinic much sooner than normal. The ease of subcutaneous injections also opens up an opportunity for home treatment, a potential boon for people who don’t want to spend their remaining time on hospital visits.

“In the future, I hope we can deliver these medicines at home,” said Hazel O’Sullivan, MBBCh, a medical lung cancer oncologist at Cork University, Ireland, who explained the issues during a session at the 2024 European Lung Cancer Congress.

She was the discussant on two studies at the meeting that highlighted the latest developments in the field, the IMscin002 study of subcutaneous atezolizumab and the PALOMA study of subcutaneous amivantamab, both mostly in NSCLC patients.

Subcutaneous atezolizumab was approved recently in Europe after its maker, Genentech/Roche, made a convincing case that its pharmacokinetics, efficacy, and safety are comparable to the intravenous (IV) version. The U.S. Food and Drug Administration is considering approval; Genentech/Roche anticipates a decision in 2024.

IMscin002 randomized 179 stage 2-4 NSCLC patients evenly to IV or subcutaneous atezolizumab for the first three cycles, then switched them for three more cycles.

Participants were then asked what version they preferred and what they wanted to continue with.

Seventy-one percent said they liked the subcutaneous version better and 80% opted to continue with it. Their main reasons were because they spent less time in the clinic and it was more comfortable.

When asked about the potential for home administration, presenter Federico Cappuzzo, MD, PhD, a medical lung cancer oncologist in Rome, said that it could be “an important option in the future,” particularly in isolated areas far away from hospitals.

The authors of new research are currently evaluating whether home administration is possible. Nurses are administering atezolizumab to patients in their homes with telemedicine monitoring.

The other subcutaneous study presented at the meeting, the PALOMA trial with amivantamab, had only 19 subjects. Administration took no more than 10 minutes, versus potentially hours, especially for the first dose. Subcutaneous amivantamab was given once a month, versus every 2 weeks for the IV formulation, during the maintenance phase of treatment.

The take-home from PALOMA is that the risk of infusion reactions is lower with subcutaneous administration (16% versus 67%) but the risk of mostly mild skin rashes is higher (79% versus 36%).

Investigation is ongoing to confirm safety, pharmacokinetic, and efficacy equivalence with the IV formulation, including in combination with other medications.

When asked about home administration of amivantamab, PALOMA lead investigator Natasha Leighl, MD, a lung, and breast cancer medical oncologist at the University of Toronto, stated that patients probably need to be watched in the clinic for the first 4 months.

The atezolizumab study was funded by maker Genentech/Roche. The amivantamab study was funded by its maker, Janssen. The amivantamab investigator, Dr. Leighl, reported grants, honoraria, and travel payments from Janssen. Dr. Cappuzzo, the investigator on the atezolizumab study, reported speaker and adviser payments from Genentech/Roche. The discussant, Dr. O’Sullivan, wasn’t involved with either company but reported payments from Amgen and AstraZeneca and travel costs covered by Takeda.

In the not-too-distant future, immunotherapy might be administered to cancer patients in their homes.

The possibility is being driven by the development of subcutaneous formulations of commonly used immune checkpoint inhibitors for non–small cell lung cancer (NSCLC) and other indications, including pembrolizumab, nivolumab, durvalumab, atezolizumab, and amivantamab.

Instead of waiting anywhere from 30 minutes to several hours for infusions into their veins, patients would spend just a few minutes being injected under the loose skin of their abdomens or thighs. Clinicians would save time and money, and patients would leave the clinic much sooner than normal. The ease of subcutaneous injections also opens up an opportunity for home treatment, a potential boon for people who don’t want to spend their remaining time on hospital visits.

“In the future, I hope we can deliver these medicines at home,” said Hazel O’Sullivan, MBBCh, a medical lung cancer oncologist at Cork University, Ireland, who explained the issues during a session at the 2024 European Lung Cancer Congress.

She was the discussant on two studies at the meeting that highlighted the latest developments in the field, the IMscin002 study of subcutaneous atezolizumab and the PALOMA study of subcutaneous amivantamab, both mostly in NSCLC patients.

Subcutaneous atezolizumab was approved recently in Europe after its maker, Genentech/Roche, made a convincing case that its pharmacokinetics, efficacy, and safety are comparable to the intravenous (IV) version. The U.S. Food and Drug Administration is considering approval; Genentech/Roche anticipates a decision in 2024.

IMscin002 randomized 179 stage 2-4 NSCLC patients evenly to IV or subcutaneous atezolizumab for the first three cycles, then switched them for three more cycles.

Participants were then asked what version they preferred and what they wanted to continue with.

Seventy-one percent said they liked the subcutaneous version better and 80% opted to continue with it. Their main reasons were because they spent less time in the clinic and it was more comfortable.

When asked about the potential for home administration, presenter Federico Cappuzzo, MD, PhD, a medical lung cancer oncologist in Rome, said that it could be “an important option in the future,” particularly in isolated areas far away from hospitals.

The authors of new research are currently evaluating whether home administration is possible. Nurses are administering atezolizumab to patients in their homes with telemedicine monitoring.

The other subcutaneous study presented at the meeting, the PALOMA trial with amivantamab, had only 19 subjects. Administration took no more than 10 minutes, versus potentially hours, especially for the first dose. Subcutaneous amivantamab was given once a month, versus every 2 weeks for the IV formulation, during the maintenance phase of treatment.

The take-home from PALOMA is that the risk of infusion reactions is lower with subcutaneous administration (16% versus 67%) but the risk of mostly mild skin rashes is higher (79% versus 36%).
