Newly released figures showing a rise in the number of men with advanced prostate cancer have laid bare long-simmering resentment among patient advocates who feel the nation’s leading cancer group has largely ignored their concerns for years.

The American Cancer Society on Jan. 13 revealed what it called “alarming” news about prostate cancer: After 2 decades of decline, the number of men diagnosed with the disease in the United States rose by 15% from 2014 to 2019.

“Most concerning,” according to the group’s CEO Karen Knudsen, PhD, MBA, is that the increase is being driven by diagnoses of advanced disease.

“Since 2011, the diagnosis of advanced-stage (regional- or distant-stage) prostate cancer has increased by 4%-5% annually and the proportion of men diagnosed with distant-stage disease has doubled,” said Dr. Knudsen at a press conference concerning the figures. “These findings underscore the importance of understanding and reducing this trend.”

The increase, which works out to be an additional 99,000 cases of prostate cancer, did not take the ACS by surprise; the group has been predicting a jump in diagnoses of the disease, which is the most common cancer in men after skin cancer, and the second most common cause of cancer death for that group.

The ACS announced a new action plan, “Improving Mortality from Prostate Cancer Together” – or IMPACT – to address the rise, especially in Black men, and to curb the increasing rate of advanced, difficult-to-treat cases.

“We must address these shifts in prostate cancer, especially in the Black community, since the incidence of prostate cancer in Black men is 70% higher than in White men and prostate cancer mortality rates in Black men are approximately two to four times higher than those in every other racial and ethnic group,” William Dahut, MD, PhD, chief scientific officer for the ACS, said at the press conference.

A study published in JAMA Network Open challenged that claim, finding that, after controlling for socioeconomic factors, race does not appear to be a significant predictor of mortality for prostate cancer.

Dr. Dahut said in an interview that IMPACT “is still [in the] early days for this initiative and more details will be coming out soon.”

Charles Ryan, MD, CEO of the Prostate Cancer Foundation, the world’s largest prostate cancer research charity, called IMPACT “extremely important work. Highlighting the disparities can only serve to benefit all men with prostate cancer, especially Black men.”
 

Bold action ... or passivity?

Overall cancer mortality has dropped 33% since 1991, averting an estimated 3.8 million deaths, according to ACS. But the story for prostate cancer is different.

The society and advocates had warned as recently as 2 years ago that prostate cancer was poised to rise again, especially advanced cases that may be too late to treat.

Leaders in the prostate cancer advocacy community praised the ACS plan for IMPACT, but some expressed frustration over what they said was ACS’ passivity in the face of long-anticipated increases in cases of the disease.

“I think prostate cancer was not high on their agenda,” said Rick Davis, founder of AnCan, which offers several support groups for patients with prostate cancer.  “It’s good to see ACS get back into the prostate cancer game.”

Mr. Davis and patient advocate Darryl Mitteldorf, LCSW, founder of Malecare, another prostate support organization, said ACS dropped patient services for prostate cancer patients a decade ago and has not been a vocal supporter of screening for levels of prostate-specific antigen (PSA) to detect prostate cancer early.

“Early detection is supposed to be their goal,” Mr. Davis said.

In 2012, the U.S. Preventive Services Task Force recommended against PSA screening, giving it a D-rating. The move prompted attacks on the task force from most advocates and many urologists.

Following this criticism, the task force recommended shared decision-making between patient and doctor, while giving PSA screening a C-rating. Now, the ACS recommends men in general at age 50 discuss prostate cancer screening with their doctor and that Black men do the same at age 45.

Mr. Mitteldorf said ACS “owes prostate cancer patients an explanation and analysis of its response to the USPTF’s downgrade of PSA testing and how that response might be related to death and instance rates.”

Mr. Mitteldorf added that male patients lost key support from ACS when the group dismantled its Man to Man group for prostate cancer patients and its Brother to Brother group for Blacks in particular.

Dr. Dahut said Man to Man “sunsetted” and was turned over to any local organization that chose to offer it. He said longtime staff didn’t have “a lot of information about [the demise of] Brother to Brother.”

For Mr. Davis, those smaller cuts add up to a much larger insult.

“Today, in 2023, ACS continues to poke a finger in the eyes of prostate cancer patients,” he said. “Since 2010, they have not given us any respect. ACS dumped its support.”

He pointed to the group’s funding priorities, noting that outlays for prostate cancer have consistently lagged behind those for breast cancer.

The ACS spent $25.3 million on breast cancer research and $6.7 million for prostate cancer in 2018, and in 2023 will designate $126.5 for breast cancer research and $43.9 million for prostate cancer.

ACS has earmarked $62 million this year for lung cancer programs and $61 million for colorectal cancer.

“Parity between breast cancer and prostate cancer would be a good start in sizing the IMPACT program,” Mr. Davis said. “After all, breast cancer and prostate cancer are hardly different in numbers today.”

Dr. Dahut denied any gender bias in research funding. He said the group makes funding decisions “based on finding the most impactful science regardless of tumor type. Our mission includes funding every cancer, every day; thus, we generally do not go into our funding cycle with any set-asides for a particular cancer.”

Mr. Davis also said the ACS data suggest the growing number of prostate cancer cases is even worse than the group has said. Although the society cites a 3% annual increase in prostate cancer diagnoses from 2014 to 2019, since 2019 the annual increase is a much more dramatic 16%. Meanwhile, the number of new cases of the disease is projected to rise from 175,000 per year in 2019 to 288,000 this year.

Dr. Dahut said the society used the 2014-2019 time frame for technical reasons, separating confirmed cases in the earlier period from estimated cases in recent years.

“We discourage comparing projected cases over time because these cases are model-based and subject to fluctuations,” Dr. Dahut said.

Changes regarding smoking, drinking, body weight, and physical activity may alter the risk for colorectal cancer (CRC), the results of a study on a large European cohort suggest.

“This is a clear message that practicing clinicians and gastroenterologists could give to their patients and to CRC screening participants to improve CRC prevention,” write Edoardo Botteri, PhD, Cancer Registry of Norway, Oslo, and colleagues in an article published in the American Journal of Gastroenterology.

Previous studies have shown a correlation between cancer in general and unhealthy lifestyle factors. They have also shown an association between weight gain and an increased risk for CRC and a reduced risk with smoking cessation. But Dr. Botteri and colleagues could not find any published research on the association of other lifestyle factors and the risk for CRC specifically, they write.

To help fill this gap, they followed 295,865 people who participated in the European Prospective Investigation into Cancer (EPIC) for a median of 7.8 years. The participants were mostly aged from 35 to 70 years and lived in Denmark, France, Germany, Greece, Italy, the Netherlands, Norway, Spain, Sweden, and the United Kingdom.

The researchers calculated a healthy lifestyle index (HLI) score on the basis of smoking status, alcohol consumption, body mass index, and physical activity. The median time between baseline and the follow-up questionnaire was 5.7 years.

They awarded points as indicated in the following table.

Colorectal cancer is the third leading cause of cancer-related death in both men and women.¹ Colonoscopy is the current gold standard for screening due to the ability to remove precancerous lesions but remains highly dependent on the quality of bowel preparation.² Poor bowel preparation has been associated with impaired adenoma detection as well as increased health care utilization due to the need for a repeat colonoscopy.³

Multiple patient factors are associated with increased risk of poor bowel preparation, including age > 60 years, male sex, diabetes mellitus, and presence of a mental health diagnosis, factors that are prevalent among the veteran population.^3-5 Text messages have been shown to improve the quality of bowel preparation by increasing patients' understanding and adherence with the preparation process. Improved adherence with bowel preparation directions is associated with a cleaner colon prior to colonoscopy, leading to a thorough examination. Studies using text messaging instructions prior to colonoscopies have also shown measurable improvement in adenoma detection rate, patient preparation-associated discomfort, and completion of colonoscopy.^6-10

In 2016, the Veterans Health Administration (VHA) introduced Annie, one of the first automated text messaging services, named after Army Lieutenant Annie Fox, the first woman to receive the Purple Heart for combat. The Annie platform allows for notifications, instructions, and simple data collection. The development of this platform allows VHA practitioners to engage and educate veterans in a similar way to other health care systems using text messaging protocols. Annie text messages have been piloted for the use of hepatitis C treatment, demonstrating promise of improved medication adherence and patient satisfaction.¹¹ We aimed to develop and pilot the Annie bowel preparation protocol to improve the quality of colonoscopy bowel preparation for outpatients at the Minneapolis Veterans Affairs Medical Center (MVAMC) in Minnesota. A secondary goal included measuring patient satisfaction with the text messaging instructions for outpatient colonoscopy preparation.

Methods

We conducted a single center, prospective, endoscopist-blinded, study with two 3-month long Plan-Do-Study-Act (PDSA) cycles to improve the text messaging bowel preparation protocol at MVAMC between January 2019 and April 2020. The MVAMC Institutional Review Board determined the quality improvement project was exempt. Veterans who had outpatient colonoscopies scheduled were included. Veterans undergoing inpatient colonoscopies or outpatients who could not be reached to obtain informed consent, lacked text message capability, declined participation, or required extended colonoscopy preparation were excluded. Per MVAMC procedures, extended colonoscopy preparation was provided to patients receiving general or monitored anesthesia care, with a history of poor bowel preparation, or with risk factors for poor preparation as determined by the ordering health care professional (HCP). Standard bowel preparation involves ingestion of 4 L of polyethylene glycol 3350 with electrolytes; extended bowel preparation requires ingestion of an additional 2 L to total 6 L and uses a different set of instructions. Additionally, the patient population requiring extended bowel preparation also includes patients with spinal cord injuries, who often are admitted for assistance with extended preparation. Patients who consented to receiving text messages were placed in the Annie intervention group, and all others were placed in the control group.

The control group received standardized patient education, including a mailed copy of bowel preparation instructions and a phone call from a gastroenterology service nurse about 1 to 2 weeks before the procedure. Current MVAMC standard of care involves a phone call from a nurse to confirm that patients have received the polyethylene glycol preparation solution, the mailed instructions, have an escort and transportation, and to answer any questions. Both the usual care and intervention group received the phone call. During this call, the Annie text messaging bowel preparation protocol was introduced; if the veteran chose to participate, consent and enrollment were completed.

On the day of the colonoscopy, veterans in the intervention group were surveyed in the waiting room about their experience receiving the text messages and soliciting feedback for improvement or surveyed via telephone call within 3 days of their procedure. Patient satisfaction was quantified with a scale from 1 (low) to 10 (high), including questions about how helpful the texts were in relation to total number, timing, and content of messages as well as whether veterans would like to receive the text messages again for future procedures.

We reviewed individual charts and collected Boston Bowel Preparation Scale (BBPS) scores to determine adequate preparation. BBPS assigns a score of 0 to 3 for the right, transverse, and left colon applied upon withdrawal after flushing and suctioning have been completed.¹² Adequate preparation is considered a total score of ≥ 6 with no segment scoring < 2. This method of preparation assessment is preferred due to its ability to account for difference in preparation quality among colonic segments, well-defined scoring characteristics, and several studies validating its use showing inter- and intraobserver reliability.¹² Follow-up studies have shown validity of the BBPS when compared with relevant outcomes such as polyp detection rate and recommended timing for repeat procedure.¹³ Variables associated with poor bowel preparation (ie, gender, prior abdominal surgery, impaired mobility, high body mass index, diabetes mellitus, stroke, dementia, any neurologic diagnosis, cirrhosis, smoking, polypharmacy [> 8 active medications], and narcotic or tricyclic antidepressant medication use) were also collected through chart review.^3-5 We note that immobility was defined by International Classification of Diseases (ICD)-9 and ICD-10 codes and prescriptions for assistive devices (ie, canes, wheelchairs, 4-wheeled walkers).

Veterans assent to be enrolled in Annie. After enrollment, veterans must text back a specific word response to an initial text message to receive the protocolized messages from the Annie program. A contact phone number to the gastrointestinal nurse line was provided for questions during business hours. The start date for the text message protocol is 6 days prior to the procedure date. If a patient rescheduled their colonoscopy, the Annie database was updated manually.

Statistical Analysis

We used both Pearson χ² test and 2-sample t test analyses to compare demographic information and patient satisfaction scores between the control and intervention groups. We compared continuous BBPS scores between Annie intervention vs control group using parametric and nonparametric independent t tests using the Mann-Whitney U test. We repeated this analysis controlling for both mental health diagnoses and age using linear regression. We were unable to survey 61 of the 187 veterans who received Annie text messages. 

RESULTS

During PDSA cycles 1 and 2, 640 veterans were scheduled for outpatient colonoscopy: 453 veterans were in the control group; 187 veterans were in the intervention group, of which 126 were surveyed. A significant percentage of veterans declined participation because they felt like they did not need reinforced education; others were not eligible for Annie due to requirement for extended bowel preparation, cancelled colonoscopy, inability to physically read text messages, or lack of cell phone.

The mean (SD) age was 65 (8) years; 184 (28.8%) had a diabetes mellitus diagnosis, and the mean (SD) body mass index was 31.6 (6.4). The Annie group was slightly more likely to have mental health diagnoses and lower age compared with the control group (Table 1).

Patient Feedback

We collected feedback from veterans after each PDSA cycle to identify areas for improvement by both in-person and telephone surveys. Based on feedback from PDSA cycle 1, we decreased the total number of text messages to create a more succinct set of instructions. The most frequently requested change involved timing the text messages to align with the exact morning a specific instruction should take place.

Patient satisfaction with the Annie text messaging service was high.

DISCUSSION

To our knowledge, this is the first report of using Annie at a VAMC for colonoscopy bowel preparation improvement. We found a statistically significant improvement in the average BBPS in those receiving Annie text messages compared with the routine care control group. We also found high levels of patient satisfaction with most patients requesting to receive them again for future procedures.

The clinical significance of a BBPS of 7.8 vs 8.2 is unclear, although any score > 6 is considered to be adequate. However, subjectively speaking, the higher the BBPS the cleaner the colon, and theoretically the easier it is to see small or flat polyps. Future steps could include calculating adenoma detection rates for those enrolled in the Annie program vs the control group.

We have received inquiries regarding potential program implementation at other facilities. Success and sustainability of the program will require long-term commitment and ideally protected time for staff. It is helpful to remember that for each person who chooses to enroll in the intervention, the program currently requires that a brief consent note is placed in the patient’s chart. Thus, depending on the facilities’ resources, it is ideal for one staff member to be the designated lead to help oversee, troubleshoot, and train additional personnel. Surveys can be intermittently used to obtain feedback for improvement but are not required for sustainability. Automated text messaging is a promising addition to medicine for clinical education and communication. Future studies should examine the clinical significance (ie, adenoma detection rates) of text messaging bowel preparation protocols.

Limitations

Our study has several limitations. First, this was a single center study, thus generalizability is limited. MVAMC represents a predominantly White, male, and rural population. Second, data are likely an underestimation of the true impact of intervention, because results do not account for patients who were turned away on day of procedure (typically still reporting brown stools at time of check-in for procedure) due to poor preparation or aborted procedures secondary to poor preparation. Only about one-third of the 640 veterans opted to receive Annie text messages.

Studies have shown veterans are willing to use technology for health care; however, access to technology and lack of training remain barriers to use.¹⁴ This has been most robustly studied at the VA in veterans experiencing mental illness and homelessness. Targeted strategies to improve veteran adoption of technology within their health care include supplying veterans with cell phones and paid data plans and providing training on specific technology-based resources.^15-17 Future improvement for the Annie platform should include improved integration with CPRS. Integration will facilitate automatic import of key information such as mobile phone number or colonoscopy procedure date. Unfortunately, this is not currently an automated process, and the manual workload of staff limits sustainability. Since our study ended, the Annie database now allows an “event date” to be programmed in to center the text message series around. This will be entered at the time of Annie enrollment and eliminate manual activation of the protocol. The issue of updating information for rescheduled procedures remains.

Conclusions

There is increasing evidence that automated text messaging is a promising addition to medicine for clinical education and communication. It continues to gain traction as a readily available and acceptable option, and many patients are willing to incorporate the technology platform into their care plan. We found high patient satisfaction with our protocol, and Annie patients had cleaner bowel preparations compared with control patients. Our study supports the use of text message reminders as an effective intervention for improving patient adherence with bowel preparation instructions. We suspect that creation of a text messaging protocol designed for patients requiring outpatient extended bowel preparation will yield great benefit. As technology continues to improve, future implementation of Annie text messaging will become increasingly seamless within the field of gastroenterology and beyond.

Colorectal cancer is the third leading cause of cancer-related death in both men and women.¹ Colonoscopy is the current gold standard for screening due to the ability to remove precancerous lesions but remains highly dependent on the quality of bowel preparation.² Poor bowel preparation has been associated with impaired adenoma detection as well as increased health care utilization due to the need for a repeat colonoscopy.³

Multiple patient factors are associated with increased risk of poor bowel preparation, including age > 60 years, male sex, diabetes mellitus, and presence of a mental health diagnosis, factors that are prevalent among the veteran population.^3-5 Text messages have been shown to improve the quality of bowel preparation by increasing patients' understanding and adherence with the preparation process. Improved adherence with bowel preparation directions is associated with a cleaner colon prior to colonoscopy, leading to a thorough examination. Studies using text messaging instructions prior to colonoscopies have also shown measurable improvement in adenoma detection rate, patient preparation-associated discomfort, and completion of colonoscopy.^6-10

In 2016, the Veterans Health Administration (VHA) introduced Annie, one of the first automated text messaging services, named after Army Lieutenant Annie Fox, the first woman to receive the Purple Heart for combat. The Annie platform allows for notifications, instructions, and simple data collection. The development of this platform allows VHA practitioners to engage and educate veterans in a similar way to other health care systems using text messaging protocols. Annie text messages have been piloted for the use of hepatitis C treatment, demonstrating promise of improved medication adherence and patient satisfaction.¹¹ We aimed to develop and pilot the Annie bowel preparation protocol to improve the quality of colonoscopy bowel preparation for outpatients at the Minneapolis Veterans Affairs Medical Center (MVAMC) in Minnesota. A secondary goal included measuring patient satisfaction with the text messaging instructions for outpatient colonoscopy preparation.

Methods

We conducted a single center, prospective, endoscopist-blinded, study with two 3-month long Plan-Do-Study-Act (PDSA) cycles to improve the text messaging bowel preparation protocol at MVAMC between January 2019 and April 2020. The MVAMC Institutional Review Board determined the quality improvement project was exempt. Veterans who had outpatient colonoscopies scheduled were included. Veterans undergoing inpatient colonoscopies or outpatients who could not be reached to obtain informed consent, lacked text message capability, declined participation, or required extended colonoscopy preparation were excluded. Per MVAMC procedures, extended colonoscopy preparation was provided to patients receiving general or monitored anesthesia care, with a history of poor bowel preparation, or with risk factors for poor preparation as determined by the ordering health care professional (HCP). Standard bowel preparation involves ingestion of 4 L of polyethylene glycol 3350 with electrolytes; extended bowel preparation requires ingestion of an additional 2 L to total 6 L and uses a different set of instructions. Additionally, the patient population requiring extended bowel preparation also includes patients with spinal cord injuries, who often are admitted for assistance with extended preparation. Patients who consented to receiving text messages were placed in the Annie intervention group, and all others were placed in the control group.

The control group received standardized patient education, including a mailed copy of bowel preparation instructions and a phone call from a gastroenterology service nurse about 1 to 2 weeks before the procedure. Current MVAMC standard of care involves a phone call from a nurse to confirm that patients have received the polyethylene glycol preparation solution, the mailed instructions, have an escort and transportation, and to answer any questions. Both the usual care and intervention group received the phone call. During this call, the Annie text messaging bowel preparation protocol was introduced; if the veteran chose to participate, consent and enrollment were completed.

On the day of the colonoscopy, veterans in the intervention group were surveyed in the waiting room about their experience receiving the text messages and soliciting feedback for improvement or surveyed via telephone call within 3 days of their procedure. Patient satisfaction was quantified with a scale from 1 (low) to 10 (high), including questions about how helpful the texts were in relation to total number, timing, and content of messages as well as whether veterans would like to receive the text messages again for future procedures.

We reviewed individual charts and collected Boston Bowel Preparation Scale (BBPS) scores to determine adequate preparation. BBPS assigns a score of 0 to 3 for the right, transverse, and left colon applied upon withdrawal after flushing and suctioning have been completed.¹² Adequate preparation is considered a total score of ≥ 6 with no segment scoring < 2. This method of preparation assessment is preferred due to its ability to account for difference in preparation quality among colonic segments, well-defined scoring characteristics, and several studies validating its use showing inter- and intraobserver reliability.¹² Follow-up studies have shown validity of the BBPS when compared with relevant outcomes such as polyp detection rate and recommended timing for repeat procedure.¹³ Variables associated with poor bowel preparation (ie, gender, prior abdominal surgery, impaired mobility, high body mass index, diabetes mellitus, stroke, dementia, any neurologic diagnosis, cirrhosis, smoking, polypharmacy [> 8 active medications], and narcotic or tricyclic antidepressant medication use) were also collected through chart review.^3-5 We note that immobility was defined by International Classification of Diseases (ICD)-9 and ICD-10 codes and prescriptions for assistive devices (ie, canes, wheelchairs, 4-wheeled walkers).

Veterans assent to be enrolled in Annie. After enrollment, veterans must text back a specific word response to an initial text message to receive the protocolized messages from the Annie program. A contact phone number to the gastrointestinal nurse line was provided for questions during business hours. The start date for the text message protocol is 6 days prior to the procedure date. If a patient rescheduled their colonoscopy, the Annie database was updated manually.

Statistical Analysis

We used both Pearson χ² test and 2-sample t test analyses to compare demographic information and patient satisfaction scores between the control and intervention groups. We compared continuous BBPS scores between Annie intervention vs control group using parametric and nonparametric independent t tests using the Mann-Whitney U test. We repeated this analysis controlling for both mental health diagnoses and age using linear regression. We were unable to survey 61 of the 187 veterans who received Annie text messages. 

RESULTS

During PDSA cycles 1 and 2, 640 veterans were scheduled for outpatient colonoscopy: 453 veterans were in the control group; 187 veterans were in the intervention group, of which 126 were surveyed. A significant percentage of veterans declined participation because they felt like they did not need reinforced education; others were not eligible for Annie due to requirement for extended bowel preparation, cancelled colonoscopy, inability to physically read text messages, or lack of cell phone.

The mean (SD) age was 65 (8) years; 184 (28.8%) had a diabetes mellitus diagnosis, and the mean (SD) body mass index was 31.6 (6.4). The Annie group was slightly more likely to have mental health diagnoses and lower age compared with the control group (Table 1).

Patient Feedback

We collected feedback from veterans after each PDSA cycle to identify areas for improvement by both in-person and telephone surveys. Based on feedback from PDSA cycle 1, we decreased the total number of text messages to create a more succinct set of instructions. The most frequently requested change involved timing the text messages to align with the exact morning a specific instruction should take place.

Patient satisfaction with the Annie text messaging service was high.

DISCUSSION

To our knowledge, this is the first report of using Annie at a VAMC for colonoscopy bowel preparation improvement. We found a statistically significant improvement in the average BBPS in those receiving Annie text messages compared with the routine care control group. We also found high levels of patient satisfaction with most patients requesting to receive them again for future procedures.

The clinical significance of a BBPS of 7.8 vs 8.2 is unclear, although any score > 6 is considered to be adequate. However, subjectively speaking, the higher the BBPS the cleaner the colon, and theoretically the easier it is to see small or flat polyps. Future steps could include calculating adenoma detection rates for those enrolled in the Annie program vs the control group.

We have received inquiries regarding potential program implementation at other facilities. Success and sustainability of the program will require long-term commitment and ideally protected time for staff. It is helpful to remember that for each person who chooses to enroll in the intervention, the program currently requires that a brief consent note is placed in the patient’s chart. Thus, depending on the facilities’ resources, it is ideal for one staff member to be the designated lead to help oversee, troubleshoot, and train additional personnel. Surveys can be intermittently used to obtain feedback for improvement but are not required for sustainability. Automated text messaging is a promising addition to medicine for clinical education and communication. Future studies should examine the clinical significance (ie, adenoma detection rates) of text messaging bowel preparation protocols.

Limitations

Our study has several limitations. First, this was a single center study, thus generalizability is limited. MVAMC represents a predominantly White, male, and rural population. Second, data are likely an underestimation of the true impact of intervention, because results do not account for patients who were turned away on day of procedure (typically still reporting brown stools at time of check-in for procedure) due to poor preparation or aborted procedures secondary to poor preparation. Only about one-third of the 640 veterans opted to receive Annie text messages.

Studies have shown veterans are willing to use technology for health care; however, access to technology and lack of training remain barriers to use.¹⁴ This has been most robustly studied at the VA in veterans experiencing mental illness and homelessness. Targeted strategies to improve veteran adoption of technology within their health care include supplying veterans with cell phones and paid data plans and providing training on specific technology-based resources.^15-17 Future improvement for the Annie platform should include improved integration with CPRS. Integration will facilitate automatic import of key information such as mobile phone number or colonoscopy procedure date. Unfortunately, this is not currently an automated process, and the manual workload of staff limits sustainability. Since our study ended, the Annie database now allows an “event date” to be programmed in to center the text message series around. This will be entered at the time of Annie enrollment and eliminate manual activation of the protocol. The issue of updating information for rescheduled procedures remains.

Conclusions

There is increasing evidence that automated text messaging is a promising addition to medicine for clinical education and communication. It continues to gain traction as a readily available and acceptable option, and many patients are willing to incorporate the technology platform into their care plan. We found high patient satisfaction with our protocol, and Annie patients had cleaner bowel preparations compared with control patients. Our study supports the use of text message reminders as an effective intervention for improving patient adherence with bowel preparation instructions. We suspect that creation of a text messaging protocol designed for patients requiring outpatient extended bowel preparation will yield great benefit. As technology continues to improve, future implementation of Annie text messaging will become increasingly seamless within the field of gastroenterology and beyond.

Radiation therapy can cause long-term dysphagia that seriously affects quality of life for survivors of head and neck (H&N) cancer.^1-3 Numerous studies have linked pharyngeal constrictor dose to long-term dysphagia, but conclusions about the dose distribution that can be safely tolerated have been inconsistent. For example, a group from the Netherlands found that the mean dose to the superior pharyngeal constrictor muscle and the supraglottic larynx were each predictive of dysphagia.⁴ A subsequent Vanderbilt study refuted these findings, reporting that these structures were not predictive but that dose to the inferior pharyngeal constrictor muscle was.⁵ Other studies have connected late dysphagia with dose to the middle pharyngeal constrictor muscle, total larynx, oral cavity, contralateral submandibular gland, contralateral parotid gland, or a combination of these structures.^6-14 NRG Oncology trials commonly evaluate dose to the “uninvolved pharynx,” which is the total pharyngeal constrictor muscle volume minus the planning target volume for the lowest dose target volume. NRG H&N trials 3, 4, 5, 6, 8, and 9 all use uninvolved pharynx mean dose  ≤ 45 Gy as a constraint to judge radiation plan quality.

Differences in methodology or patient population may explain the inconsistency of prior studies on dosimetric predictors of dysphagia, but it is possible that these studies did not evaluate the optimal metric for dysphagia. This study evaluates a novel organ at risk, the contralateral pharyngeal constrictor muscle, to determine whether dose to this structure is predictive of late swallowing function. The study also compares a constraint based on this structure to the NRG uninvolved pharynx constraint mentioned earlier.

Methods

This study is a retrospective review of patients treated at the Richard L. Roudebush Veterans Affairs (VA) Medical Center in Indianapolis, Indiana. Patients were identified by searching the VA Cancer Registry for patients treated for H&N squamous cell carcinoma between September 1, 2016, and August 30, 2019. Eligible sites included cancers of the nasopharynx, oropharynx, hypopharynx, larynx and oral cavity, as well as H&N cancer of an unknown primary site. Only patients treated with primary radiation with concurrent systemic therapy were included. Patients were excluded if they had prior surgery or radiation to the H&N.

The pharyngeal constrictor muscles were contoured per the techniques described by Bhide and colleagues.¹¹ The contralateral constrictor was defined as the half of the constrictor volume contralateral to the primary site. For midline tumors, the side of the neck with a lower volume of lymph node metastases was judged to be the contralateral side.

Results

The VA Cancer Registry identified 113 patients treated for H&N cancer during the study period. Of these, 55 patients met the inclusion criteria. No patients were lost to follow-up. The median follow-up was 29 months. The median age was 67 years (range, 41-83) (Table 1).

All patients were treated with intensity-modulated radiotherapy (IMRT). Patients treated with a sequential boost had an initial dose of 54 Gy and/or 50 Gy, followed by a boost to a total of 70 Gy at 2 Gy per fraction. Patients treated with a simultaneous integrated boost (SIB) technique received 69.96 Gy in 33 fractions, with elective volumes treated to 54.45 Gy in 33 fractions. Both patients with nasopharyngeal cancer were treated with SIB plans and had an intermediate dose volume of 59.4 Gy.

Systemic therapy was weekly cisplatin in 41 patients (75%) and cetuximab in 14 (25%). Twenty percent of patients receiving cisplatin switched to an alternative agent during treatment, most commonly carboplatin.

Forty-nine patients (89%) had a G-tube placed before starting radiation. G-tubes were in place for an interval of 0 to 47 months (mean, 8.6); 12 (22%) had a G-tube > 12 months. After completion of radiation, 18 patients (33%) had an abnormal MBS. These were done 1 to 50 months (mean, 14.8) after completion of radiation. Abnormal MBS occurred ≥ 12 months after radiation in 9 patients, 5 of whom had their G-tube in place for less than a year.

Forty-six patients (84%) survived more than 1 year and could be evaluated for late swallowing function. One-year dysphagia was seen in 17 (37%) of these patients. Recurrence was seen in 20 patients (36%), with locoregional recurrence in 12 (60%) of these cases. Recurrence occurred at a range of 0 to 15 months (mean, 5.6). Neither recurrence (P = .69) nor locoregional recurrence (P = .11) was associated with increased 1-year dysphagia.

In patients who could be evaluated for long-term swallowing function, contralateral constrictor V60 ranged from 0% to 100% (median, 51%). V60 was < 40% in 18 patients (39%). With V60 < 40%, there was a 6% rate of 1-year dysphagia compared with 57% for V60 ≥ 40% (P < .001).

Patients with contralateral constrictor V60 < 40 and V60 ≥ 40 both had a mean age of 65 years. χ² analysis did not show a difference in T stage or systemic treatment but did show that patients with V60 < 40% were more likely to have N1 disease (P = .01), and less likely to have N2 disease (P = .01) compared with patients with V60 ≥ 40%. The difference in 1-year dysphagia between N0 to N1 patients (27%) and N2 to N3 patients (46%) was not statistically significant (P = .19).

In patients who could be evaluated for long-term swallowing function, the uninvolved pharynx volume median of the total constrictor volume was 32% (range, < 1%-62%). The uninvolved pharynx mean dose ranged from 28 to 68 Gy (median, 45). When the uninvolved pharynx mean dose was < 45 Gy, 1-year dysphagia was 22% compared with 52% with a dose ≥ 45 Gy (P = .03).

Discussion

This is the first study to link contralateral constrictor dose to long-term dysphagia in patients treated with radiation for H&N cancer. Editing the boost volume off air cavities was associated with lower contralateral constrictor V60 and with less long-term dysphagia. This may indicate that optimizing plans to meet a contralateral constrictor constraint can reduce rates of long-term dysphagia.

The most useful clinical predictors are those that identify a patient at low risk for toxicity. These constraints are useful because they reassure physicians that treatments will have a favorable risk/benefit ratio while identifying plans that may need modification before starting treatment.

The contralateral constrictor outperformed the uninvolved pharynx in identifying patients at low risk for long-term dysphagia. This difference could not be overcome by decreasing the threshold of the pharynx constraint, as 17% of patients with dysphagia had a mean dose of < 40 Gy to the uninvolved pharynx, which was not statistically significant.

An advantage of contralateral constrictor is that it is independent of planning target volume (PTV) size. The uninvolved pharynx structure depends on the PTV contour, so it may obscure a connection between PTV size and dysphagia.

In the context of a clinical trial, only measuring dose to the uninvolved pharynx may allow more plans to meet constraints, but even in NRG trials, physicians have some control over target volumes. For example, NRG HN009, a national trial for patients with H&N cancer, recommends editing the CTV_7000 (clinical target volume treated to 70 Gy) off air cavities but does not define how much the volume should be cropped or specify protocol violations if the volume is not cropped.¹⁵ Furthermore, constraints used in clinical trials are often adopted for use outside the trial, where physicians have extensive control over target volumes.

The broad range of uninvolved pharynx volume relative to total constrictor volume confounds predictions using this variable. For example, according to the NRG constraint, a patient with an uninvolved pharynx mean dose of 44 Gy will have a low risk of dysphagia even if this structure is only 1% of the total constrictor. The contralateral constrictor is always about 50% of the total constrictor volume, which means that predictions using this structure will not be confounded by the same variation in volume size.

Figure 2 shows a representative patient who met the NRG uninvolved pharynx constraint but developed long-term dysphagia.

Limitations

This study is limited by its single institution, retrospective design, small sample size, and by all patients being male. The high correlation between air cavity editing and the use of SIB makes it impossible to assess the impact of each technique individually. Patients with contralateral constrictor V60 < 40% were less likely to have N2 disease, but N2 to N3 disease did not predict higher 1-year dysphagia, so the difference in N-category cannot fully explain the difference in 1-year dysphagia. It is possible that unreported factors, such as CTV, may contribute significantly to swallowing function. Nevertheless, within the study population, contralateral constrictor dose was able to identify a group with a low rate of long-term dysphagia.

Conclusions

Contralateral constrictor dose is a promising predictor of late dysphagia for patients with H&N cancer treated with radiation with concurrent systemic therapy. Contralateral constrictor V60 < 40% was able to identify a group of patients with a low rate of 1-year dysphagia in this single-center retrospective study. The correlation between air cavity editing and contralateral constrictor V60 suggests that contralateral constrictor dose may depend partly on technique. Further studies are needed to see if the contralateral constrictor dose can be used to predict long-term dysphagia prospectively and in other patient populations.

Radiation therapy can cause long-term dysphagia that seriously affects quality of life for survivors of head and neck (H&N) cancer.^1-3 Numerous studies have linked pharyngeal constrictor dose to long-term dysphagia, but conclusions about the dose distribution that can be safely tolerated have been inconsistent.

NRG H&N trials 3, 4, 5, 6, 8, and 9 all use uninvolved pharynx mean dose  ≤ 45 Gy as a constraint to judge radiation plan quality.

Systemic therapy was weekly cisplatin in 41 patients (75%) and cetuximab in 14 (25%). Twenty percent of patients receiving cisplatin switched to an alternative agent during treatment, most commonly carboplatin.

Forty-nine patients (89%) had a G-tube placed before starting radiation. G-tubes were in place for an interval of 0 to 47 months (mean, 8.6); 12 (22%) had a G-tube > 12 months. After completion of radiation, 18 patients (33%) had an abnormal MBS. These were done 1 to 50 months (mean, 14.8) after completion of radiation. Abnormal MBS occurred ≥ 12 months after radiation in 9 patients, 5 of whom had their G-tube in place for less than a year.

Forty-six patients (84%) survived more than 1 year and could be evaluated for late swallowing function. One-year dysphagia was seen in 17 (37%) of these patients. Recurrence was seen in 20 patients (36%), with locoregional recurrence in 12 (60%) of these cases. Recurrence occurred at a range of 0 to 15 months (mean, 5.6). Neither recurrence (P = .69) nor locoregional recurrence (P = .11) was associated with increased 1-year dysphagia.

In patients who could be evaluated for long-term swallowing function, contralateral constrictor V60 ranged from 0% to 100% (median, 51%). V60 was < 40% in 18 patients (39%). With V60 < 40%, there was a 6% rate of 1-year dysphagia compared with 57% for V60 ≥ 40% (P < .001).

Patients with contralateral constrictor V60 < 40 and V60 ≥ 40 both had a mean age of 65 years. χ² analysis did not show a difference in T stage or systemic treatment but did show that patients with V60 < 40% were more likely to have N1 disease (P = .01), and less likely to have N2 disease (P = .01) compared with patients with V60 ≥ 40%. The difference in 1-year dysphagia between N0 to N1 patients (27%) and N2 to N3 patients (46%) was not statistically significant (P = .19).

In patients who could be evaluated for long-term swallowing function, the uninvolved pharynx volume median of the total constrictor volume was 32% (range, < 1%-62%). The uninvolved pharynx mean dose ranged from 28 to 68 Gy (median, 45). When the uninvolved pharynx mean dose was < 45 Gy, 1-year dysphagia was 22% compared with 52% with a dose ≥ 45 Gy (P = .03).

Discussion

This is the first study to link contralateral constrictor dose to long-term dysphagia in patients treated with radiation for H&N cancer. Editing the boost volume off air cavities was associated with lower contralateral constrictor V60 and with less long-term dysphagia. This may indicate that optimizing plans to meet a contralateral constrictor constraint can reduce rates of long-term dysphagia.

The most useful clinical predictors are those that identify a patient at low risk for toxicity. These constraints are useful because they reassure physicians that treatments will have a favorable risk/benefit ratio while identifying plans that may need modification before starting treatment.

The contralateral constrictor outperformed the uninvolved pharynx in identifying patients at low risk for long-term dysphagia. This difference could not be overcome by decreasing the threshold of the pharynx constraint, as 17% of patients with dysphagia had a mean dose of < 40 Gy to the uninvolved pharynx, which was not statistically significant.

An advantage of contralateral constrictor is that it is independent of planning target volume (PTV) size. The uninvolved pharynx structure depends on the PTV contour, so it may obscure a connection between PTV size and dysphagia.

In the context of a clinical trial, only measuring dose to the uninvolved pharynx may allow more plans to meet constraints, but even in NRG trials, physicians have some control over target volumes. For example, NRG HN009, a national trial for patients with H&N cancer, recommends editing the CTV_7000 (clinical target volume treated to 70 Gy) off air cavities but does not define how much the volume should be cropped or specify protocol violations if the volume is not cropped.¹⁵ Furthermore, constraints used in clinical trials are often adopted for use outside the trial, where physicians have extensive control over target volumes.

The broad range of uninvolved pharynx volume relative to total constrictor volume confounds predictions using this variable. For example, according to the NRG constraint, a patient with an uninvolved pharynx mean dose of 44 Gy will have a low risk of dysphagia even if this structure is only 1% of the total constrictor. The contralateral constrictor is always about 50% of the total constrictor volume, which means that predictions using this structure will not be confounded by the same variation in volume size.

Figure 2 shows a representative patient who met the NRG uninvolved pharynx constraint but developed long-term dysphagia.

Limitations

This study is limited by its single institution, retrospective design, small sample size, and by all patients being male. The high correlation between air cavity editing and the use of SIB makes it impossible to assess the impact of each technique individually. Patients with contralateral constrictor V60 < 40% were less likely to have N2 disease, but N2 to N3 disease did not predict higher 1-year dysphagia, so the difference in N-category cannot fully explain the difference in 1-year dysphagia. It is possible that unreported factors, such as CTV, may contribute significantly to swallowing function. Nevertheless, within the study population, contralateral constrictor dose was able to identify a group with a low rate of long-term dysphagia.

Conclusions

Contralateral constrictor dose is a promising predictor of late dysphagia for patients with H&N cancer treated with radiation with concurrent systemic therapy. Contralateral constrictor V60 < 40% was able to identify a group of patients with a low rate of 1-year dysphagia in this single-center retrospective study. The correlation between air cavity editing and contralateral constrictor V60 suggests that contralateral constrictor dose may depend partly on technique. Further studies are needed to see if the contralateral constrictor dose can be used to predict long-term dysphagia prospectively and in other patient populations.

Radiation therapy can cause long-term dysphagia that seriously affects quality of life for survivors of head and neck (H&N) cancer.^1-3 Numerous studies have linked pharyngeal constrictor dose to long-term dysphagia, but conclusions about the dose distribution that can be safely tolerated have been inconsistent. For example, a group from the Netherlands found that the mean dose to the superior pharyngeal constrictor muscle and the supraglottic larynx were each predictive of dysphagia.⁴ A subsequent Vanderbilt study refuted these findings, reporting that these structures were not predictive but that dose to the inferior pharyngeal constrictor muscle was.⁵ Other studies have connected late dysphagia with dose to the middle pharyngeal constrictor muscle, total larynx, oral cavity, contralateral submandibular gland, contralateral parotid gland, or a combination of these structures.^6-14 NRG Oncology trials commonly evaluate dose to the “uninvolved pharynx,” which is the total pharyngeal constrictor muscle volume minus the planning target volume for the lowest dose target volume. NRG H&N trials 3, 4, 5, 6, 8, and 9 all use uninvolved pharynx mean dose  ≤ 45 Gy as a constraint to judge radiation plan quality.

Differences in methodology or patient population may explain the inconsistency of prior studies on dosimetric predictors of dysphagia, but it is possible that these studies did not evaluate the optimal metric for dysphagia. This study evaluates a novel organ at risk, the contralateral pharyngeal constrictor muscle, to determine whether dose to this structure is predictive of late swallowing function. The study also compares a constraint based on this structure to the NRG uninvolved pharynx constraint mentioned earlier.

Methods

This study is a retrospective review of patients treated at the Richard L. Roudebush Veterans Affairs (VA) Medical Center in Indianapolis, Indiana. Patients were identified by searching the VA Cancer Registry for patients treated for H&N squamous cell carcinoma between September 1, 2016, and August 30, 2019. Eligible sites included cancers of the nasopharynx, oropharynx, hypopharynx, larynx and oral cavity, as well as H&N cancer of an unknown primary site. Only patients treated with primary radiation with concurrent systemic therapy were included. Patients were excluded if they had prior surgery or radiation to the H&N.

The pharyngeal constrictor muscles were contoured per the techniques described by Bhide and colleagues.¹¹ The contralateral constrictor was defined as the half of the constrictor volume contralateral to the primary site. For midline tumors, the side of the neck with a lower volume of lymph node metastases was judged to be the contralateral side.

Results

The VA Cancer Registry identified 113 patients treated for H&N cancer during the study period. Of these, 55 patients met the inclusion criteria. No patients were lost to follow-up. The median follow-up was 29 months. The median age was 67 years (range, 41-83) (Table 1).

All patients were treated with intensity-modulated radiotherapy (IMRT). Patients treated with a sequential boost had an initial dose of 54 Gy and/or 50 Gy, followed by a boost to a total of 70 Gy at 2 Gy per fraction. Patients treated with a simultaneous integrated boost (SIB) technique received 69.96 Gy in 33 fractions, with elective volumes treated to 54.45 Gy in 33 fractions. Both patients with nasopharyngeal cancer were treated with SIB plans and had an intermediate dose volume of 59.4 Gy.

Systemic therapy was weekly cisplatin in 41 patients (75%) and cetuximab in 14 (25%). Twenty percent of patients receiving cisplatin switched to an alternative agent during treatment, most commonly carboplatin.

Forty-nine patients (89%) had a G-tube placed before starting radiation. G-tubes were in place for an interval of 0 to 47 months (mean, 8.6); 12 (22%) had a G-tube > 12 months. After completion of radiation, 18 patients (33%) had an abnormal MBS. These were done 1 to 50 months (mean, 14.8) after completion of radiation. Abnormal MBS occurred ≥ 12 months after radiation in 9 patients, 5 of whom had their G-tube in place for less than a year.

Forty-six patients (84%) survived more than 1 year and could be evaluated for late swallowing function. One-year dysphagia was seen in 17 (37%) of these patients. Recurrence was seen in 20 patients (36%), with locoregional recurrence in 12 (60%) of these cases. Recurrence occurred at a range of 0 to 15 months (mean, 5.6). Neither recurrence (P = .69) nor locoregional recurrence (P = .11) was associated with increased 1-year dysphagia.

In patients who could be evaluated for long-term swallowing function, contralateral constrictor V60 ranged from 0% to 100% (median, 51%). V60 was < 40% in 18 patients (39%). With V60 < 40%, there was a 6% rate of 1-year dysphagia compared with 57% for V60 ≥ 40% (P < .001).

Patients with contralateral constrictor V60 < 40 and V60 ≥ 40 both had a mean age of 65 years. χ² analysis did not show a difference in T stage or systemic treatment but did show that patients with V60 < 40% were more likely to have N1 disease (P = .01), and less likely to have N2 disease (P = .01) compared with patients with V60 ≥ 40%. The difference in 1-year dysphagia between N0 to N1 patients (27%) and N2 to N3 patients (46%) was not statistically significant (P = .19).

In patients who could be evaluated for long-term swallowing function, the uninvolved pharynx volume median of the total constrictor volume was 32% (range, < 1%-62%). The uninvolved pharynx mean dose ranged from 28 to 68 Gy (median, 45). When the uninvolved pharynx mean dose was < 45 Gy, 1-year dysphagia was 22% compared with 52% with a dose ≥ 45 Gy (P = .03).

Discussion

This is the first study to link contralateral constrictor dose to long-term dysphagia in patients treated with radiation for H&N cancer. Editing the boost volume off air cavities was associated with lower contralateral constrictor V60 and with less long-term dysphagia.

DENVER – As best practices for screening and surveillance of high-risk cutaneous squamous cell carcinoma (CSCC) continue to evolve, mounting evidence supports the use of radiologic imaging.

In a study published in 2020, Emily Ruiz, MD, MPH, and colleagues identified 87 CSCC tumors in 83 patients who underwent baseline or surveillance imaging primary at the Brigham and Women’s Hospital Mohs Surgery Clinic and the Dana-Farber Cancer Institute High-Risk Skin Cancer Clinic, both in Boston, from Jan. 1, 2017, to June 1, 2019. Of the 87 primary CSCCs, 48 (58%) underwent surveillance imaging. The researchers found that imaging detected additional disease in 26 patients, or 30% of cases, “whether that be nodal metastasis, local invasion beyond what was clinically accepted, or in-transit disease,” Dr. Ruiz, academic director of the Mohs and Dermatologic Surgery Center at Brigham and Women’s, said during the annual meeting of the American Society for Dermatologic Surgery. “But if you look at the 16 nodal metastases in this cohort, all were picked up on imaging and not on clinical exam.”

Since publication of these results, Dr. Ruiz routinely considers baseline radiologic imaging in T2b and T3 tumors; borderline T2a tumors (which she said they are now calling “T2a high,” for those who have one risk factor plus another intermediate risk factor),” and T2a tumors in patients who are profoundly immunosuppressed.

“My preference is to always do [the imaging] before treatment unless I’m up-staging them during surgery,” said Dr. Ruiz, who also directs the High-Risk Skin Cancer Clinic at Dana Farber. “We have picked up nodal metastases before surgery, which enables us to create a good therapeutic plan for our patients before we start operating. Then we image them every 6 months or so for about 2 years. Sometimes we will extend that out to 3 years.”

Some clinicians use sentinel lymph node biopsy (SLNB) as a diagnostic test, but there are mixed results about its prognostic significance. A retrospective observational study of 720 patients with CSCC found that SLNB provided no benefit regarding further metastasis or tumor-specific survival, compared with those who received routine observation and follow-up, “but head and neck surgeons in the U.S. are putting together some prospective data from multiple centers,” Dr. Ruiz said. “I think in the coming years, you will have more multicenter data to inform us as to whether to do SLNB or not.”

Surgery may be the mainstay of treatment for resectable SCC, but the emerging role of neoadjuvant therapeutics is changing the way oncologists treat these tumors. For example, in a phase 2 trial recently published in the New England Journal of Medicine, 79 patients with stage II-IV CSCC received up to four doses of immunotherapy with the programmed death receptor–1 (PD-1) blocker cemiplimab administered every 3 weeks. The primary endpoint was a pathologic complete response, defined as the absence of viable tumor cells in the surgical specimen at a central laboratory. The researchers observed that 68% of patients had an objective response.

“These were patients with localized tumors that were either very aggressive or had nodal metastases,” said Dr, Ruiz, who was the site primary investigator at Dana Farber and a coauthor of the NEJM study. “This has altered the way we approach treating our larger tumors that could be resectable but have a lot of disease either locally or in the nodal basin. We think that we can shrink down the tumor and make it easier to resect, but also there is the possibility or improving outcomes.”

At Brigham and Women’s and the Dana Farber, she and her colleagues consider immunotherapy for multiple recurrent tumors that have been previously irradiated; cases of large tumor burden locally or in the nodal basin; tumors that have a complex surgical plan; cases where there is a low likelihood of achieving clear surgical margins; and cases of in-transit disease.

“We use two to four doses of immunotherapy prior to surgery and assess the tumor response after two doses both clinically and radiologically,” she said. “If the tumor continues to grow, we would do surgery sooner.”

The side-effect profile of immunotherapy is another consideration. “Some patients are not appropriate for a neoadjuvant immunotherapy approach, such as transplant patients,” she said.

According to the latest National Comprehensive Cancer Network guidelines, surgery with or without adjuvant radiation is the current standard of care for treating CSCC. These guidelines were developed without much data to support the use of radiation, but a 20-year retrospective cohort study at Brigham and Women’s Hospital and the Cleveland Clinic Foundation found that adjuvant radiation following margin resection in high T-stage CSCC cut the risk of local and locoregional recurrence in half.

“This is something that radiation oncologists have told us for years, but there was no data to support it, so it was nice to see that borne out in clinical data,” said Dr. Ruiz, the study’s lead author. The 10% risk of local recurrence observed in the study “may not be high enough for some of our older patients, so we wanted to see if we could identify a group of high tumors that had higher risk of local recurrence,” she said. They found that patients who had a greater than 20% risk of poor outcome were those with recurrent tumors, those with tumors 6 cm or greater in size, and those with all four BWH risk factors (tumor diameter ≥ 2 cm, poorly differentiated histology, perineural invasion ≥ 0.1 mm, or tumor invasion beyond fat excluding bone invasion).

“Those risks were also cut in half if you added radiation,” she said. “So, the way I now approach counseling patients is, I try to estimate their baseline risk as best I can based on the tumor itself. I tell them that if they want to do adjuvant radiation it would cut the risk in half. Some patients are too frail and want to pass on it, while others are very interested.”

Of patients who did not receive radiation but had a disease recurrence, just under half of tumors were salvageable, about 25% died of their disease, and 23% had persistent disease. “I think this does support using radiation earlier on for the appropriate patient,” Dr. Ruiz said. “I consider the baseline risks [and] balance that with the patient’s comorbidities.”

Limited data exists on adjuvant immunotherapy for CSCC, but two ongoing randomized prospective clinical trials underway are studying the PD-1 inhibitors cemiplimab and pembrolizumab versus placebo. “We don’t have data yet, but prior to randomization, patients undergo surgery with macroscopic gross resection of all disease,” Dr. Ruiz said. “All tumors receive ART [adjuvant radiation therapy] prior to randomization”

Dr. Ruiz disclosed that she is a consultant for Sanofi, Regeneron, Genentech, and Jaunce Therapeutics. She is also a member of the advisory board for Checkpoint Therapeutics and is an investigator for Merck, Sanofi, and Regeneron.

“This is something that radiation oncologists have told us for years, but there was no data to support it, so it was nice to see that borne out in clinical data,” said Dr. Ruiz, the study’s lead author. The 10% risk of local recurrence observed in the study “may not be high enough for some of our older patients, so we wanted to see if we could identify a group of high tumors that had higher risk of local recurrence,” she said. They found that patients who had a greater than 20% risk of poor outcome were those with recurrent tumors, those with tumors 6 cm or greater in size, and those with all four BWH risk factors (tumor diameter ≥ 2 cm, poorly differentiated histology, perineural invasion ≥ 0.1 mm, or tumor invasion beyond fat excluding bone invasion).

“Those risks were also cut in half if you added radiation,” she said. “So, the way I now approach counseling patients is, I try to estimate their baseline risk as best I can based on the tumor itself. I tell them that if they want to do adjuvant radiation it would cut the risk in half. Some patients are too frail and want to pass on it, while others are very interested.”

Of patients who did not receive radiation but had a disease recurrence, just under half of tumors were salvageable, about 25% died of their disease, and 23% had persistent disease. “I think this does support using radiation earlier on for the appropriate patient,” Dr. Ruiz said. “I consider the baseline risks [and] balance that with the patient’s comorbidities.”

Limited data exists on adjuvant immunotherapy for CSCC, but two ongoing randomized prospective clinical trials underway are studying the PD-1 inhibitors cemiplimab and pembrolizumab versus placebo. “We don’t have data yet, but prior to randomization, patients undergo surgery with macroscopic gross resection of all disease,” Dr. Ruiz said. “All tumors receive ART [adjuvant radiation therapy] prior to randomization”

Dr. Ruiz disclosed that she is a consultant for Sanofi, Regeneron, Genentech, and Jaunce Therapeutics. She is also a member of the advisory board for Checkpoint Therapeutics and is an investigator for Merck, Sanofi, and Regeneron.

SAN DIEGO—As patients with cancer live longer, pain is going to become an even bigger challenge for clinicians, a palliative care specialist told cancer specialists in a presentation at the annual meeting of the Association of VA Hematology/Oncology (AVAHO) in September, and decisions about treatment are becoming more complicated amid the opioid epidemic.

Fortunately, guidelines and clinical experience offer helpful insight into the best practices, said hematologist/oncologist Andrea Ruskin, MD, medical director of palliative care at Veterans Administration (VA) Connecticut Healthcare System (VACHS).

As Ruskin pointed out, two-thirds of newly diagnosed cancer patients are living for at least 5 years, “but with this progress comes challenges.” More than one-third (37%) of cancer survivors report cancer pain, 21% have noncancer pain, and 45% have both. About 5% to 8% of VA cancer survivors use opioids for the long term, she said, although there have been few studies in this population.

Among patients with head and neck cancer, specifically, chronic pain affects 45%, and severe pain affects 11%. Subclinical PTSD, depression, anxiety, and low quality of life are common in this population. “We may cure them, but they have a lot of issues going forward.”

One key strategy is to perform a comprehensive pain assessment at the first visit, and then address pain at every subsequent visit. She recommended a physician resource from the American Society of Clinical Oncology, and a template may be useful to provide helpful questions, Ruskin said.

At VACHS certain questions are routine. “Is pain interfering with your function? Sometimes people say it’s always a 10, but it’s not affecting function at all. Ask if the medicine is working. And how are they taking it? Sometimes they say, ‘I’m taking that for sleep,’ and we say ‘No, Mr. Smith, that is not a sleep medication.’”

Be aware that some patients may use nonmedical opioids, she said. And set expectations early on. “Safe opioid use starts with the very first prescription,” she said. “If I have somebody with myeloma or head and neck cancer, I make it very clear that my goal is that we want you off the opioids after the radiation or once the disease is in remission. I really make an effort at the very beginning to make sure that we're all on the same page.”

As you continue to see a patient, consider ordering urine tests, she said, not as a punitive measure but to make sure you’re offering the safest and most effective treatment. “We don’t do it to say ‘no, no, no.’ We do it for safety and to make sure they’re not getting meds elsewhere.”

What are the best practices when pain doesn’t go away? Should they stay on opioids? According to Ruskin, few evidence-based guidelines address the “more nuanced care” that patients need when their pain lasts for months or years.

But there are useful resources. Ruskin highlighted the National Comprehensive Cancer Network’s survivorship guidelines, and she summarized a few of the available painkiller options. “Opioids are great, and adjuvants are so-so. They work in some people, but we definitely have room for improvement.”

What if patients have persistent opioid use after cancer recovery? “I try to taper if I can, and I try to explain why I’m tapering. It could take months or years to taper patients,” she said. And consider transitioning the patient to buprenorphine, a drug that treats both pain and opioid use disorder, if appropriate. “You don’t need a waiver if you use it for pain. It’s definitely something we’re using more of.”

One important step is to bring in colleagues to help. Psychologists, chiropractors, physical therapists, physiatrists, and pain pharmacists can all be helpful, she said. “Learn about your VA resources and who can partner with you to help these complicated patients. They’re all at your fingertips.”

SAN DIEGO–The Louis Stokes Cleveland VA Medical Center in Ohio dramatically reduced wait times for bone marrow biopsies and treatment by ditching the radiology department and opening a weekly clinic devoted to the procedures, a cancer care team reported at the annual meeting of the Association of VA Hematology/Oncology (AVAHO) September 16 to 18, 2022.

The average time from biopsy order to procedure fell by more than two-thirds from 23.1 days to 7.0 days, and the time from order to diagnosis dipped from 27.8 days to 11.6 days. The time from treatment fell from 54.8 days to 20.2 days.

The new strategy aims to avoid sending patients to the radiology department and treat them in a clinic within the cancer center instead. “It’s great to be able to keep as many hematology/oncology–related things such as infusion, scheduling, and procedures within our department. It provides continuity for the veteran, and it’s helpful for them from that aspect,” said nurse practitioner Kyle Stimpert, MSN, RN, ACNP, of VA Northeast Ohio Healthcare System.

As the cancer team reported in an abstract presented at the AVAHO meeting, “bone marrow biopsies often need to be performed expeditiously to alleviate patient concerns and quickly determine a diagnosis and treatment plan. However, with increasing subspecialization, there are fewer hematology/oncology providers available to perform this procedure.”

The Cleveland VA tried to address this problem by sending patients to interventional radiology, but it still took weeks for bone marrow biopsies to be performed: From August 4, 2020, to August 12, 2021, when 140 biopsies were performed, the average time from order to procedure was 23.1 days. The time from order to diagnosis was 27.8 days, and from order to treatment was 54.8 days.

The bone marrow biopsies provide insight into diseases such as hematologic malignancies and myelodysplastic syndromes, Stimpert said. The procedures may lead to diagnoses or reveal how treatment is progressing.

In 2021, new leadership sought to shrink the wait times. “We put together a small team and started brainstorming,” said oncology clinical nurse specialist Alecia Smalheer, MSN, APRN, OCN, in an interview. With the help of staff who’d come from other facilities, she said, “we were able to see what was being done in surrounding community hospitals and come up with a model and a checklist.”

The team modified a space to create a new weekly, half-day bone marrow biopsy clinic. They also worked on procedures, documentation, education of patients, and training of staff, Smalheer said.

After implementation in the summer of 2021, the biopsy clinic performed 89 procedures through August 31, 2022. The average time from order to procedure was 7.0 days. The time to diagnosis was 11.6 days, and the time to treatment was 20.2 days. The differences between the pre-implementation and postimplementation periods were statistically significant. (P < .001 for each).

The biopsy clinic now sees about 3 to 4 patients a week. “Just yesterday, I had a vet whose cancer was going down. I was able to just do this bone marrow right there, and it was amazing. He didn’t have to go home [and come back],” Stimpert said. “A lot of patients travel a far distance or on oxygen, or it’s hard for them to get around. Coming to the facility for repeat appointments can just take a lot out of them. So it’s really nice to be able to get it all done in one visit.”

There are multiple benefits to shortening wait times, Smalheer said. “They can start treatment much sooner… but it also alleviates some of the emotional distress of waiting. They still have some waiting to do, but it’s definitely not as long.”

And, Stimpert added, patients are familiar with the infusion center and will see faces they know.

As for cost, the biopsy clinic may save money due to several factors related to how and where the biopsy procedures are performed, Stimpert said.

No disclosures are reported.

SAN DIEGO—From coast to coast, 10 US Department of Veterans Affairs (VA) medical centers are holding meetings designed to help clinicians and colleagues talk openly about touchy workplace topics, such as compassion, burnout, and medical errors. New data suggests that “Schwartz Rounds” have tremendous power to change how medical professionals cope, communicate, and commiserate.

At the VA Connecticut Healthcare System (VACHS), nearly all (98%) respondents who took part in Schwartz Round sessions rated them as either good or excellent, 89% reported feeling less isolated in their work with patients, 98% had new insights into the perspectives and experiences of colleagues, and 93% felt more open to communicating with colleagues, reported oncologist Edward Perry, MD, of VA Connecticut and Yale University School of Medicine, in a presentation here at the annual meeting of the Association of VA Hematology/Oncology (AVAHO) held September 16 to 18, 2022.

Schwartz Rounds have been around for 25 years and are named after the late Ken Schwartz, a 40-year-old Boston health care attorney who wrote movingly in 1995 about the “exquisite compassion” he experienced while being treated for advanced lung cancer—and the risk that the rapidly evolving health care system would lose its sense of empathy. 

The Boston-based nonprofit Schwartz Center for Compassionate Healthcare facilitates Schwartz Rounds, which are now held at about 600 health care organizations around the world. That number includes the 10 VA medical centers, mostly in the Northeast (Massachusetts, New York, Connecticut, and New Hampshire) but also in California, Illinois, and Minnesota.

Site teams work with the Schwartz Center to plan the rounds and gather data about their effectiveness. “Unlike traditional clinical or ethics rounds, this is not a didactic or problem-solving session. The focus is not on what happened, but how those who were involved felt. In other words, the human dimension of medicine,” Dr. Perry said. “There are no right or wrong answers. Everything that is said during short rounds is confidential. We do encourage people to continue discussion of the general themes afterward but not to share any specifics of what was discussed.”

At VACHS, Schwartz rounds began shortly before the COVID-19 pandemic, Perry said, and they’ve been held virtually since the first meeting. “Schwartz Rounds are open to all employees, trainees, and students at the institution. Anyone with a VA badge is welcome to attend,” he said. “We're averaging about 150 attendees per session.”

Speakers have addressed social/emotional topics, including delivering bad news to patients, maintaining compassion during adversity, and providing compassionate care to patients with substance use disorders.

The VACHS survey of Schwartz Rounds participants had a 50% response rate, with about 400 people responding to each question. Nearly all (98%) said they planned to attend the rounds again, and 55% agreed that a specific discussion “suggests that changes may be needed in departmental or institutional policies or practices.”

The administration has agreed to continue the Schwartz Rounds in light of the positive results, Perry said. As he noted, the Schwartz Center charges dues and initiation fees. The Marjorie Stanzler Financial Aid Fund underwrites the initiation fees for qualifying organizations, including VA facilities.

As for lessons, he said the topics of Schwartz Rounds “should be emotionally resonant. They should involve multiple disciplines and perspectives. They should illuminate an issue or experience that is not often discussed. And should inspire participants to share their own experiences and highlight instances of compassionate care—or barriers to providing compassionate care.”

Speakers have addressed social/emotional topics, including delivering bad news to patients, maintaining compassion during adversity, and providing compassionate care to patients with substance use disorders.

The VACHS survey of Schwartz Rounds participants had a 50% response rate, with about 400 people responding to each question. Nearly all (98%) said they planned to attend the rounds again, and 55% agreed that a specific discussion “suggests that changes may be needed in departmental or institutional policies or practices.”

The administration has agreed to continue the Schwartz Rounds in light of the positive results, Perry said. As he noted, the Schwartz Center charges dues and initiation fees. The Marjorie Stanzler Financial Aid Fund underwrites the initiation fees for qualifying organizations, including VA facilities.

As for lessons, he said the topics of Schwartz Rounds “should be emotionally resonant. They should involve multiple disciplines and perspectives. They should illuminate an issue or experience that is not often discussed. And should inspire participants to share their own experiences and highlight instances of compassionate care—or barriers to providing compassionate care.”

Using artificial intelligence, researchers have developed an algorithm that can help improve the prediction of colorectal cancer (CRC) recurrence.

The QuantCRC algorithm can identify patients with CRC who might be able to skip chemotherapy, given a low probability of recurrence, and identify those patients at high risk for recurrence who may benefit from more intensive treatment or follow-up, the researchers say.

“For patients with colon cancer, the algorithm gives oncologists another tool to help guide therapy and follow-up,” Rish Pai, MD, PhD, a pathologist at Mayo Clinic, Phoenix, who developed the tool, said in a news release.

The study was published online in the journal Gastroenterology.

The tool is a deep-learning segmentation algorithm developed using 6,468 digitized CRC images. It quantifies 15 features from a CRC image and uses them to improve prediction of recurrence.

“QuantCRC can identify different regions within the tumor and extract quantitative data from these regions,” Dr. Pai explained.

“The algorithm converts an image into a set of numbers that is unique to that tumor. The large number of tumors that we analyzed allowed us to learn which features were most predictive of tumor behavior. We can now apply what we have learned to new colon cancers to predict how the tumor will behave,” Dr. Pai said.

The researchers developed a prognostic model incorporating stage, mismatch repair, and QuantCRC that resulted in a concordance (c)-index of 0.714 in the internal test and 0.744 in the external cohort. Removing QuantCRC from the model reduced the c-index to 0.679 in the external cohort.

Using QuantCRC, they identified prognostic risk groups for recurrence, which provided a hazard ratio of 2.24 for low- versus high-risk stage III CRC and 2.36 for low- versus high-risk stage II CRC, in the external cohort after adjusting for established risk factors.

The predicted median 36-month recurrence rate for high-risk stage III CRC was 32.7% versus 13.4% for low-risk stage III CRC and 15.8% for high-risk stage II CRC versus 5.4% for low-risk stage II CRC, the researchers report.

QuantCRC provides a “powerful adjunct” to routine pathologic reporting of CRC, and a prognostic model using QuantCRC can improve prediction of recurrence-free survival, they write.

Looking ahead, Dr. Pai plans to use QuantCRC to better understand mechanisms of tumor recurrence and see if it can predict the response to certain treatments, like immunotherapy, he said.

Funding for this study was provided in part by the Colon Cancer Family Registry, which is supported in part by funding from the National Cancer Institute and National Institutes of Health. Dr. Pai reports consulting income from Alimentiv, Eli Lilly, AbbVie, Allergan, Genentech, and PathAI outside of the submitted work.
