When Childhood Cancer Survivors Face Sexual Challenges
Childhood cancers represent a diverse group of neoplasms, and thanks to advances in treatment, survival rates have improved significantly. Today, more than 80%-85% of children diagnosed with cancer in developed countries survive into adulthood.
This increase in survival has brought new challenges, however. Compared with the general population, childhood cancer survivors (CCS) are at a notably higher risk for early mortality, developing secondary cancers, and experiencing various long-term clinical and psychosocial issues stemming from their disease or its treatment.
Long-term follow-up care for CCS is a complex and evolving field. Despite ongoing efforts to establish global and national guidelines, current evidence indicates that the care and management of these patients remain suboptimal.
The disruptions caused by cancer and its treatment can interfere with normal physiological and psychological development, leading to issues with sexual function. This aspect of health is critical as it influences not just physical well-being but also psychosocial, developmental, and emotional health.
Characteristics and Mechanisms
Sexual functioning encompasses the physiological and psychological aspects of sexual behavior, including desire, arousal, orgasm, sexual pleasure, and overall satisfaction.
As CCS reach adolescence or adulthood, they often face sexual and reproductive issues, particularly as they enter romantic relationships.
Sexual functioning is a complex process that relies on the interaction of various factors, including physiological health, psychosexual development, romantic relationships, body image, and desire.
Despite its importance, the impact of childhood cancer on sexual function is often overlooked, even though cancer and its treatments can have lifelong effects.
Sexual Function in CCS
A recent review aimed to summarize the existing research on sexual function among CCS, highlighting assessment tools, key stages of psychosexual development, common sexual problems, and the prevalence of sexual dysfunction.
The review study included 22 studies published between 2000 and 2022, comprising two qualitative, six cohort, and 14 cross-sectional studies.
Most CCS reached all key stages of psychosexual development at an average age of 29.8 years. Although some milestones were achieved later than is typical, many survivors felt they reached these stages at the appropriate time. Sexual initiation was less common among those who had undergone intensive neurotoxic treatments, such as those diagnosed with brain tumors or leukemia in childhood.
In a cross-sectional study of CCS aged 17-39 years, about one third had never engaged in sexual intercourse, 41.4% reported never experiencing sexual attraction, 44.8% were dissatisfied with their sex lives, and many rarely felt sexually attractive to others. Another study found that common issues among CCS included a lack of interest in sex (30%), difficulty enjoying sex (24%), and difficulty becoming aroused (23%). However, comparing and analyzing these problems was challenging due to the lack of standardized assessment criteria.
The prevalence of sexual dysfunction among CCS ranged from 12.3% to 46.5%. For males, the prevalence ranged from 12.3% to 54.0%, while for females, it ranged from 19.9% to 57.0%.
Factors Influencing Sexual Function
The review identified the following four categories of factors influencing sexual function in CCS: Demographic, treatment-related, psychological, and physiological.
Demographic factors: Gender, age, education level, relationship status, income level, and race all play roles in sexual function.
Female survivors reported more severe sexual dysfunction and poorer sexual health than did male survivors. Age at cancer diagnosis, age at evaluation, and the time since diagnosis were closely linked to sexual experiences. Patients diagnosed with cancer during childhood tended to report better sexual function than those diagnosed during adolescence.
Treatment-related factors: The type of cancer and intensity of treatment, along with surgical history, were significant factors. Surgeries involving the spinal cord or sympathetic nerves, as well as a history of prostate or pelvic surgery, were strongly associated with erectile dysfunction in men. In women, pelvic surgeries and treatments to the pelvic area were commonly linked to sexual dysfunction.
The association between treatment intensity and sexual function was noted across several studies, although the results were not always consistent. For example, testicular radiation above 10 Gy was positively correlated with sexual dysfunction. Women who underwent more intensive treatments were more likely to report issues in multiple areas of sexual function, while men in this group were less likely to have children.
Among female CCS, certain types of cancer, such as germ cell tumors, renal tumors, and leukemia, present a higher risk for sexual dysfunction. Women who had CNS tumors in childhood frequently reported problems like difficulty in sexual arousal, low sexual satisfaction, infrequent sexual activity, and fewer sexual partners, compared with survivors of other cancers. Survivors of acute lymphoblastic leukemia and those who underwent hematopoietic stem cell transplantation (HSCT) also showed varying degrees of impaired sexual function, compared with the general population. The HSCT group showed significant testicular damage, including reduced testicular volumes, low testosterone levels, and low sperm counts.
Psychological factors: These factors, such as emotional distress, play a significant role in sexual dysfunction among CCS. Symptoms like anxiety, nervousness during sexual activity, and depression are commonly reported by those with sexual dysfunction. The connection between body image and sexual function is complex. Many CCS with sexual dysfunction express concern about how others, particularly their partners, perceived their altered body image due to cancer and its treatment.
Physiological factors: In male CCS, low serum testosterone levels and low lean muscle mass are linked to an increased risk for sexual dysfunction. Treatments involving alkylating agents or testicular radiation, and surgery or radiotherapy targeting the genitourinary organs or the hypothalamic-pituitary region, can lead to various physiological and endocrine disorders, contributing to sexual dysfunction. Despite these risks, there is a lack of research evaluating sexual function through the lens of the hypothalamic-pituitary-gonadal axis and neuroendocrine pathways.

Low HPV Vaccination in the United States Is a Public Health ‘Failure’
This transcript has been edited for clarity.
I would like to briefly discuss what I consider to be a very discouraging report and one that I believe we as an oncology society and, quite frankly, as a medical community need to deal with.
The manuscript I’m referring to is from the United States Department of Health and Human Services, titled, “Human Papillomavirus Vaccination Coverage in Children Ages 9-17 Years: United States, 2022.” This particular analysis looked at the coverage of both men and women — young boys and young girls, I would say — receiving at least one dose of the recommended human papillomavirus (HPV) vaccination.
Since 2006, girls have been recommended to receive HPV vaccination; for boys, it’s been since 2011. Certainly, the time period that we’re considering falls within the recommendations based on overwhelmingly positive data. Now, today, still, the recommendation is for more than one vaccine. Obviously, there may be evidence in the future that a single vaccination may be acceptable or appropriate. But today, it’s more than one.
In this particular analysis, they were looking at just a single vaccination. The vaccines have targeted young individuals, both male and female children aged 11-12 years, but it’s certainly acceptable to look starting at age 9.
What is the bottom line? At least one dose of the HPV vaccination was given to 38.6% of children aged 9-17 years in 2022. We are talking about a cancer-preventive vaccine, which on the basis of population-based data in the United States, but also in other countries, is incredibly effective in preventing HPV-associated cancers. This not only includes cervical cancer, but also a large percentage of head and neck cancers.
For this vaccine, which is incredibly safe and incredibly effective, in this country, only 38.6% have received even a single dose. It is noted that the individuals with private insurance had a higher rate, at 41.5%, than individuals with no insurance, at only 20.7%.
In my opinion, this is clearly a failure of our public health establishment at all levels. My own focus has been in gynecologic cancers. I’ve seen young women with advanced cervical cancer, and this is a disease we can prevent. Yet, this is where we are.
For those of you who are interested in cancer prevention or public health, I think this is a very sobering statistic. It’s my plea and my hope that we can, as a society, somehow do something about it.
I thank you for listening. I would encourage you to think about this question if you’re in this area.

BRCA Mutations in Men: Important but Often Overlooked
BRCA1 and BRCA2 pathogenic variants carry well-known associations with breast and ovarian cancers in women, which has led to robust clinical guidelines for early genetic testing and risk-reduction strategies.
Male carriers of BRCA1/2 pathogenic variants also face an increased risk for cancer, particularly of the prostate, pancreas, and breast.
However, men often fly under the radar.
“Most people (including their clinicians) are unaware of their carrier status,” Heather Cheng, MD, PhD, with University of Washington, Seattle, and colleagues explained in a comprehensive review on the subject, published in JAMA Oncology. Most are also unaware of “the associated cancer risks, and management recommendations” for BRCA carriers.
The testing gap in males may exist, in part, because of a “general lack of awareness” that BRCA gene mutations can be passed down to children from both the mother and father, Elisa Port, MD, chief of breast surgery for the Mount Sinai Health System in New York City, told this news organization.
A daughter can inherit a mutated BRCA gene that puts her at risk for breast or ovarian cancer from her mother’s or father’s family and, similarly, a son can inherit a mutated BRCA gene from either side of the family that puts him at an increased risk for developing prostate and other cancers, explained Dr. Port, director of the Center of Excellence for Breast Cancer at The Tisch Cancer Institute at Mount Sinai.
Considering family history and genetics on both sides of the family is important when assessing cancer risk in men and women, Dr. Port said.
BRCA Mutations in Men: What’s the Risk?
Although fewer than 1% of all breast cancers occur in men, when men do carry a BRCA mutation, their risk for breast cancer can increase considerably. The lifetime risk for breast cancer can be as high as 9% in male BRCA2 carriers and up to 1.2% in BRCA1 carriers.
BRCA1/2 mutations also put men at increased risk for pancreatic and prostate cancers.
For pancreatic cancer, male BRCA1 carriers have a nearly twofold increased risk compared with the general population, with a lifetime risk of 3%. BRCA2 carriers have a three- to nearly eightfold increased risk, with a lifetime risk up to 7%.
Male BRCA1 carriers face a nearly fourfold increased risk of developing prostate cancer and an absolute lifetime risk of 15%-45%. Male BRCA2 carriers have a five- to ninefold increased risk for prostate cancer, with an absolute lifetime risk between 27% and 60%.
When to Test, When to Screen?
Despite the increased risk for several cancers associated with BRCA mutations, many men are not offered genetic testing.
BRCA1/2 genetic testing in men is “ultra-important but underutilized and is an evolving unmet need that the field needs to address,” Kai Tsao, MD MS, medical director of the Medical Oncology Prostate Cancer Program at Mount Sinai in New York City, told this news organization.
For men considering genetic testing, in Dr. Tsao’s experience, barriers may include fear that insurance may not cover the test and that a positive test may increase insurance premiums, as well as concerns about what the test result may mean for them and their family.
Even for confirmed BRCA carriers, cancer screening guidelines for men vary.
For breast screening in men, there’s limited data to inform guidelines. The National Cancer Center Network currently recommends breast awareness and teaching self-examination starting at age 35 and recommends men with BRCA variants consider yearly mammograms starting at age 50, or 10 years before the earliest male breast cancer diagnosis in the family.
Data show that screening mammography in men at high-risk for breast cancer yields similar cancer detection rates in men and women, “suggesting mammography screening may be valuable in male BRCA carriers,” the review authors noted. And, in a recent study of men with BRCA1/2 pathogenic variants, most (71%) recommended for screening mammography completed their screening.
The European Society for Medical Oncology (ESMO) has similar screening recommendations but focuses only on men with BRCA2 mutations and suggests breast ultrasonography as well as mammography as a screening option.
The larger “issue is the general population doesn’t think of breast cancer when they think of men, which may delay seeking medical attention,” said Melissa Fana, MD, of NYU Grossman Long Island School of Medicine and NYU Langone Health, who wasn’t involved in the review.
For pancreatic cancer, guidelines suggest BRCA1/2 carriers be screened for pancreatic cancer starting at age 50, or 10 years before the earliest known pancreatic cancer in the family, although the guidelines vary on the role family history should play.
And for prostate cancer, current guidelines recommend male BRCA carriers begin prostate-specific antigen screening between age 40 and 45 years, although recommendations on screening intervals and start age vary. ESMO recommendations are similar but only apply to BRCA2 carriers.
A male patient with a BRCA1/2 variant is typically referred for genetic counseling as well, Dr. Tsao explained. But “the challenge is that we don’t have a very good healthcare infrastructure right now” to follow through with that, he added. “Oftentimes a patient will wait many months or even more than a year for a genetic counseling appointment.”
To help improve these issues, Mount Sinai recently launched a comprehensive BRCA program for men and women that offers genetic testing and counseling for patients and family members.
Overall, identifying more male BRCA1/2 carriers will “maximize opportunities for cancer early detection, targeted risk management, and cancer treatment for males, along with facilitating opportunities for risk reduction and prevention in their family members, thereby decreasing the burden of hereditary cancer,” Dr. Cheng and colleagues concluded.
Support for the review was provided in part by BRCA Research and Cure Alliance and the Men & BRCA Program at the Basser Center for BRCA. Cheng reported grants from Promontory Pharmaceutics, Medivation, Sanofi, Janssen, royalties from UpToDate, nonfinancial support from Color Health, personal fees from AstraZeneca, BRCA Research and Cure Alliance (CureBRCA) outside the submitted work. Dr. Port, Dr. Tsao, and Dr. Fana had no conflicts of interest.

And, in a recent study of men with BRCA1/2 pathogenic variants, most (71%) recommended for screening mammography completed their screening.
The European Society for Medical Oncology (ESMO) has similar screening recommendations but focuses only on men with BRCA2 mutations and suggests breast ultrasonography as well as mammography as a screening option.
The larger “issue is the general population doesn’t think of breast cancer when they think of men, which may delay seeking medical attention,” said Melissa Fana, MD, of NYU Grossman Long Island School of Medicine and NYU Langone Health, who wasn’t involved in the review.
For pancreatic cancer, guidelines suggest BRCA1/2 carriers be screened for pancreatic cancer starting at age 50, or 10 years before the earliest known pancreatic cancer in the family, although the guidelines vary on the role family history should play.
And for prostate cancer, current guidelines recommend male BRCA carriers begin prostate-specific antigen screening between age 40 and 45 years, although recommendations on screening intervals and start age vary. ESMO recommendations are similar but only apply to BRCA2 carriers.
A male patient with a BRCA1/2 variant is typically referred for genetic counseling as well, Dr. Tsao explained. But “the challenge is that we don’t have a very good healthcare infrastructure right now” to follow through with that, he added. “Oftentimes a patient will wait many months or even more than a year for a genetic counseling appointment.”
To help improve these issues, Mount Sinai recently launched a comprehensive BRCA program for men and women that offers genetic testing and counseling for patients and family members.
Overall, identifying more male BRCA1/2 carriers will “maximize opportunities for cancer early detection, targeted risk management, and cancer treatment for males, along with facilitating opportunities for risk reduction and prevention in their family members, thereby decreasing the burden of hereditary cancer,” Dr. Cheng and colleagues concluded.
Support for the review was provided in part by BRCA Research and Cure Alliance and the Men & BRCA Program at the Basser Center for BRCA. Cheng reported grants from Promontory Pharmaceutics, Medivation, Sanofi, Janssen, royalties from UpToDate, nonfinancial support from Color Health, personal fees from AstraZeneca, BRCA Research and Cure Alliance (CureBRCA) outside the submitted work. Dr. Port, Dr. Tsao, and Dr. Fana had no conflicts of interest.

BRCA1 and BRCA2 pathogenic variants carry well-known associations with breast and ovarian cancers in women, which has led to robust clinical guidelines for early genetic testing and risk-reduction strategies.
Male carriers of BRCA1/2 pathogenic variants also face an increased risk for cancer, particularly of the prostate, pancreas, and breast.
However, men often fly under the radar.
“Most people (including their clinicians) are unaware of their carrier status,” Heather Cheng, MD, PhD, with University of Washington, Seattle, and colleagues explained in a comprehensive review on the subject, published in JAMA Oncology. Most are also unaware of “the associated cancer risks, and management recommendations” for BRCA carriers.
The testing gap in males may exist, in part, because of a “general lack of awareness” that BRCA gene mutations can be passed down to children from both the mother and father, Elisa Port, MD, chief of breast surgery for the Mount Sinai Health System in New York City, told this news organization.
A daughter can inherit a mutated BRCA gene that puts her at risk for breast or ovarian cancer from her mother’s or father’s family and, similarly, a son can inherit a mutated BRCA gene from either side of the family that puts him at an increased risk for developing prostate and other cancers, explained Dr. Port, director of the Center of Excellence for Breast Cancer at The Tisch Cancer Institute at Mount Sinai.
Considering family history and genetics on both sides of the family is important when assessing cancer risk in men and women, Dr. Port said.
BRCA Mutations in Men: What’s the Risk?
Although fewer than 1% of all breast cancers occur in men, when men do carry a BRCA mutation, their risk for breast cancer can increase considerably. The lifetime risk for breast cancer can be as high as 9% in male BRCA2 carriers and up to 1.2% in BRCA1 carriers.
BRCA1/2 mutations also put men at increased risk for pancreatic and prostate cancers.
For pancreatic cancer, male BRCA1 carriers have a nearly twofold increased risk compared with the general population, with a lifetime risk of 3%. BRCA2 carriers have a three- to nearly eightfold increased risk, with a lifetime risk up to 7%.
Male BRCA1 carriers face a nearly fourfold increased risk of developing prostate cancer and an absolute lifetime risk of 15%-45%. Male BRCA2 carriers have a five- to ninefold increased risk for prostate cancer, with an absolute lifetime risk between 27% and 60%.
When to Test, When to Screen?
Despite the increased risk for several cancers associated with BRCA mutations, many men are not offered genetic testing.
BRCA1/2 genetic testing in men is “ultra-important but underutilized and is an evolving unmet need that the field needs to address,” Kai Tsao, MD MS, medical director of the Medical Oncology Prostate Cancer Program at Mount Sinai in New York City, told this news organization.
For men considering genetic testing, in Dr. Tsao’s experience, barriers may include fear that insurance may not cover the test and that a positive test may increase insurance premiums, as well as concerns about what the test result may mean for them and their family.
Even for confirmed BRCA carriers, cancer screening guidelines for men vary.
For breast screening in men, there’s limited data to inform guidelines. The National Cancer Center Network currently recommends breast awareness and teaching self-examination starting at age 35 and recommends men with BRCA variants consider yearly mammograms starting at age 50, or 10 years before the earliest male breast cancer diagnosis in the family.
Data show that screening mammography in men at high-risk for breast cancer yields similar cancer detection rates in men and women, “suggesting mammography screening may be valuable in male BRCA carriers,” the review authors noted.

Immunotherapy May Be Overused in Dying Patients With Cancer
Chemotherapy has fallen out of favor for treating cancer toward the end of life. The toxicity is too high, and the benefit, if any, is often too low.
Immunotherapy, however, has been taking its place.
This means “there are patients who are getting immunotherapy who shouldn’t,” said Yale University, New Haven, Connecticut, surgical oncologist Sajid Khan, MD, senior investigator on a recent study that highlighted the growing use of these agents in patients’ last month of life.
What’s driving this trend, and how can oncologists avoid overtreatment with immunotherapy at the end of life?
The N-of-1 Patient
With immunotherapy at the end of life, “each of us has had our N-of-1” where a patient bounces back with a remarkable and durable response, said Don Dizon, MD, a gynecologic oncologist at Brown University, Providence, Rhode Island.
He recalled a patient with sarcoma who did not respond to chemotherapy. But after Dr. Dizon started her on immunotherapy, everything turned around. She has now been in remission for 8 years and counting.
The possibility of an unexpected or remarkable responder is seductive. And the improved safety of immunotherapy over chemotherapy adds to the allure.
Meanwhile, patients are often desperate. It’s rare for someone to be ready to stop treatment, Dr. Dizon said. Everybody “hopes that they’re going to be the exceptional responder.”
At the end of the day, the question often becomes: “Why not try immunotherapy? What’s there to lose?”
This thinking may be prompting broader use of immunotherapy in late-stage disease, even in instances with no Food and Drug Administration indication and virtually no supportive data, such as for metastatic ovarian cancer, Dr. Dizon said.
Back to Earth
The problem with the hopeful approach is that end-of-life turnarounds with immunotherapy are rare, and there’s no way at the moment to predict who will have one, said Laura Petrillo, MD, a palliative care physician at Massachusetts General Hospital, Boston.
Even though immunotherapy generally comes with fewer adverse events than chemotherapy, catastrophic side effects are still possible.
Dr. Petrillo recalled a 95-year-old woman with metastatic cancer who was largely asymptomatic.
She had a qualifying mutation for a checkpoint inhibitor, so her oncologist started her on one. The patient never bounced back from the severe colitis the agent caused, and she died of complications in the hospital.
Although such reactions with immunotherapy are uncommon, less serious problems caused by the agents can still have a major impact on a person’s quality of life. Low-grade diarrhea, for instance, may not sound too bad, but in a patient’s daily life, it can translate to six or more episodes a day.
Even with no side effects, prescribing immunotherapy can mean that patients with limited time left spend a good portion of it at an infusion clinic instead of at home. These patients are also less likely to be referred to hospice and more likely to be admitted to and die in the hospital.
And with treatments that can cost $20,000 per dose, financial toxicity becomes a big concern.
In short, some of the reasons why chemotherapy is not recommended at the end of life also apply to immunotherapy, Dr. Petrillo said.
Prescribing Decisions
Recent research highlights the growing use of immunotherapy at the end of life.
Dr. Khan’s retrospective study found, for instance, that the percentage of patients starting immunotherapy in the last 30 days of life increased by about fourfold to fivefold over the study period for the three cancers analyzed — stage IV melanoma, lung, and kidney cancers.
Among the population that died within 30 days, the percentage receiving immunotherapy increased over the study periods — 0.8%-4.3% for melanoma, 0.9%-3.2% for NSCLC, and 0.5%-2.6% for kidney cell carcinoma — prompting the conclusion that immunotherapy prescriptions in the last month of life are on the rise.
Prescribing immunotherapy in patients who ultimately died within 1 month occurred more frequently at low-volume, nonacademic centers than at academic or high-volume centers, and outcomes varied by practice setting.
Patients had better survival outcomes overall when receiving immunotherapy at academic or high-volume centers — a finding Dr. Khan said is worth investigating further. Possible explanations include better management of severe immune-related side effects at larger centers and more caution when prescribing immunotherapy to “borderline” candidates, such as those with several comorbidities.
Importantly, given the retrospective design, Dr. Khan and colleagues already knew which patients prescribed immunotherapy died within 30 days of initiating treatment.
More specifically, 5192 of 71,204 patients who received immunotherapy (7.3%) died within a month of initiating therapy, while 66,012 (92.7%) lived beyond that point.
The study, however, did not assess how the remaining 92.7% who lived beyond 30 days fared on immunotherapy and the differences between those who lived less than 30 days and those who survived longer.
Knowing the outcome of patients at the outset of the analysis still leaves open the question of when immunotherapy can extend life and when it can’t for the patient in front of you.
To avoid overtreating at the end of life, it’s important to have “the same standard that you have for giving chemotherapy. You have to treat it with the same respect,” said Moshe Chasky, MD, a community medical oncologist with Alliance Cancer Specialists in Philadelphia, Pennsylvania. “You can’t just be throwing” immunotherapy around “at the end of life.”
While there are no clear predictors of risk and benefit, there are some factors to help guide decisions.
As with chemotherapy, Dr. Petrillo said performance status is key. Dr. Petrillo and colleagues found that median overall survival with immune checkpoint inhibitors for advanced non–small cell lung cancer was 14.3 months in patients with an Eastern Cooperative Oncology Group performance score of 0-1 but only 4.5 months with scores of ≥ 2.
Dr. Khan also found that immunotherapy survival is, unsurprisingly, worse in patients with high metastatic burdens and more comorbidities.
“You should still consider immunotherapy for metastatic melanoma, non–small cell lung cancer, and renal cell carcinoma,” Dr. Khan said. The message here is to “think twice before using” it, especially in comorbid patients with widespread metastases.
“Just because something can be done doesn’t always mean it should be done,” he said.
At Yale, when Dr. Khan works, immunotherapy decisions are considered by a multidisciplinary tumor board. At Mass General, immunotherapy has generally moved to the frontline setting, and the hospital no longer prescribes checkpoint inhibitors to hospitalized patients because the cost is too high relative to the potential benefit, Dr. Petrillo explained.
Still, with all the uncertainties about risk and benefit, counseling patients is a challenge. Dr. Dizon called it “the epitome of shared decision-making.”
Dr. Petrillo noted that it’s critical not to counsel patients based solely on the anecdotal patients who do surprisingly well.
“It’s hard to mention that and not have that be what somebody anchors on,” she said. But that speaks to “how desperate people can feel, how hopeful they can be.”
Dr. Khan, Dr. Petrillo, and Dr. Chasky all reported no relevant conflicts of interest.

Can Addressing Depression Reduce Chemo Toxicity in Older Adults?
TOPLINE:
METHODOLOGY:
- Researchers conducted a secondary analysis of a randomized controlled trial to evaluate whether greater reductions in grade 3 chemotherapy-related toxicities occurred with geriatric assessment-driven interventions vs standard care.
- A total of 605 patients aged 65 years and older with any stage of solid malignancy were included, with 402 randomized to the intervention arm and 203 to the standard-of-care arm.
- Mental health was assessed using the Mental Health Inventory 13, and chemotherapy toxicity was graded by the National Cancer Institute Common Terminology Criteria for Adverse Events, version 4.0.
- Patients in the intervention arm received recommendations from a multidisciplinary team based on their baseline GA, while those in the standard-of-care arm received only the baseline assessment results.
- The study was conducted at City of Hope National Medical Center in Duarte, California, and patients were followed throughout treatment or for up to 6 months from starting chemotherapy.
TAKEAWAY:
- According to the authors, patients with depression had increased chemotherapy toxicity in the standard-of-care arm (70.7% vs 54.3%; P = .02) but not in the GA-driven intervention arm (54.3% vs 48.5%; P = .27).
- The association between depression and chemotherapy toxicity was also seen after adjustment for the Cancer and Aging Research Group toxicity score (odds ratio, [OR], 1.98; 95% CI, 1.07-3.65) and for demographic, disease, and treatment factors (OR, 2.00; 95% CI, 1.03-3.85).
- No significant association was found between anxiety and chemotherapy toxicity in either the standard-of-care arm (univariate OR, 1.07; 95% CI, 0.61-1.88) or the GA-driven intervention arm (univariate OR, 1.15; 95% CI, 0.78-1.71).
- The authors stated that depression was associated with increased odds of hematologic-only toxicities (OR, 2.50; 95% CI, 1.13-5.56) in the standard-of-care arm.
- An analysis of a small subgroup found associations between elevated anxiety symptoms and increased risk for hematologic and nonhematologic chemotherapy toxicities.
IN PRACTICE:
“The current study showed that elevated depression symptoms are associated with increased risk of severe chemotherapy toxicities in older adults with cancer. This risk was mitigated in those in the GA intervention arm, which suggests that addressing elevated depression symptoms may lower the risk of toxicities,” the authors wrote. “Overall, elevated anxiety symptoms were not associated with risk for severe chemotherapy toxicity.”

LIMITATIONS:
The thresholds for depression and anxiety used in the Mental Health Inventory 13 were based on an English-speaking population, which may not be fully applicable to Chinese- and Spanish-speaking patients included in the study. Depression and anxiety were not evaluated by a mental health professional or with a structured interview to assess formal diagnostic criteria. Psychiatric medication used at the time of baseline GA was not included in the analysis. The study is a secondary analysis of a randomized controlled trial, and it is not known which components of the interventions affected mental health.

- The association between depression and chemotherapy toxicity was also seen after adjustment for the Cancer and Aging Research Group toxicity score (odds ratio, [OR], 1.98; 95% CI, 1.07-3.65) and for demographic, disease, and treatment factors (OR, 2.00; 95% CI, 1.03-3.85).
- No significant association was found between anxiety and chemotherapy toxicity in either the standard-of-care arm (univariate OR, 1.07; 95% CI, 0.61-1.88) or the GA-driven intervention arm (univariate OR, 1.15; 95% CI, 0.78-1.71).
- The authors stated that depression was associated with increased odds of hematologic-only toxicities (OR, 2.50; 95% CI, 1.13-5.56) in the standard-of-care arm.
- An analysis of a small subgroup found associations between elevated anxiety symptoms and increased risk for hematologic and nonhematologic chemotherapy toxicities.
IN PRACTICE:
“The current study showed that elevated depression symptoms are associated with increased risk of severe chemotherapy toxicities in older adults with cancer. This risk was mitigated in those in the GA intervention arm, which suggests that addressing elevated depression symptoms may lower the risk of toxicities,” the authors wrote. “Overall, elevated anxiety symptoms were not associated with risk for severe chemotherapy toxicity.”

TOPLINE:
METHODOLOGY:
- Researchers conducted a secondary analysis of a randomized controlled trial to evaluate whether greater reductions in grade 3 chemotherapy-related toxicities occurred with geriatric assessment-driven interventions vs standard care.
- A total of 605 patients aged 65 years and older with any stage of solid malignancy were included, with 402 randomized to the intervention arm and 203 to the standard-of-care arm.
- Mental health was assessed using the Mental Health Inventory 13, and chemotherapy toxicity was graded by the National Cancer Institute Common Terminology Criteria for Adverse Events, version 4.0.
- Patients in the intervention arm received recommendations from a multidisciplinary team based on their baseline GA, while those in the standard-of-care arm received only the baseline assessment results.
- The study was conducted at City of Hope National Medical Center in Duarte, California, and patients were followed throughout treatment or for up to 6 months from starting chemotherapy.
TAKEAWAY:
- According to the authors, patients with depression had increased chemotherapy toxicity in the standard-of-care arm (70.7% vs 54.3%; P = .02) but not in the GA-driven intervention arm (54.3% vs 48.5%; P = .27).

FDA Approves First Engineered Cell Therapy for a Solid Tumor
Afami-cel — the first engineered cell therapy for a solid tumor — is indicated specifically for adults with unresectable or metastatic synovial sarcoma who have received prior chemotherapy, are positive for several human leukocyte antigens (HLAs), and whose tumors express melanoma-associated antigen A4, as determined by FDA-authorized companion diagnostic devices.
The single-dose treatment targets solid tumors expressing melanoma-associated antigen A4, a protein highly expressed in synovial sarcoma.
Synovial sarcoma is a rare form of cancer, which affects about 1000 people in the US each year. Malignant cells develop and form a tumor in soft tissues, often in the extremities.
“Adults with metastatic synovial sarcoma, a life-threatening form of cancer, often face limited treatment options in addition to the risk of cancer spread or recurrence,” Nicole Verdun, MD, director of the Office of Therapeutic Products in the FDA’s Center for Biologics Evaluation and Research, said in the agency press release announcing the approval. “Today’s approval represents a significant milestone in the development of an innovative, safe and effective therapy for patients with this rare but potentially fatal disease.”
T-cell receptor therapy, like chimeric antigen receptor (CAR) T-cell (CAR-T) therapy, involves altering patient T cells to fight cancer. While CAR-T therapy inserts an artificial receptor to target a specific surface protein on cancer cells, the T-cell receptor therapy modifies existing receptors to recognize an array of antigens on the surface of cancer cells — a promising strategy for targeting solid tumors.
The accelerated approval of afami-cel was based on the phase 2 SPEARHEAD-1 trial in 44 patients with synovial sarcoma who received a single infusion of the therapy. The trial had enrolled 52 patients, but 8 did not receive afami-cel, including 3 who died and 1 who withdrew.
According to the FDA announcement, the overall response rate was 43.2%, with a median time to response of 4.9 weeks. The median duration of response was 6 months (95% CI, 4.6 months to not reached). Among patients who responded, 39% had a duration of response of 12 months or longer.
“These results suggest that a one-time treatment with afami-cel has the potential to extend life while allowing responders to go off chemotherapy,” said lead investigator Sandra D’Angelo, MD, a sarcoma specialist at Memorial Sloan Kettering Cancer Center in New York City, in a company press release.
The prescribing information includes a boxed warning for serious or fatal cytokine release syndrome.
The most common nonlaboratory adverse reactions, occurring in at least 20% of patients, included cytokine release syndrome, nausea, vomiting, fatigue, infections, pyrexia, constipation, dyspnea, tachycardia, hypotension, diarrhea, and edema. The most common grade 3 or 4 laboratory abnormalities, occurring in at least 20% of patients, included decreased lymphocyte count, neutrophil count, white cell blood count, red blood cell, and platelet count.
The recommended dose is between 2.68x109 to 10x109 MAGE-A4 T-cell receptor–positive T-cells. The FDA notice specifies not using a leukodepleting filter or prophylactic systemic corticosteroids.
The list price for the one-time therapy is $727,000, according to Fierce Pharma.

FDA Expands Dostarlimab-gxly Approval for Endometrial Cancer
Prior FDA approval of the combination was granted for adults with primary advanced or recurrent endometrial cancer that was mismatch repair deficient (dMMR) or microsatellite instability–high (MSI-H).
The expanded approval, granted following a priority review, was based on efficacy and safety demonstrated in the randomized, controlled, multicenter RUBY trial, which included 494 patients who were randomized to receive the dostarlimab-gxly regimen or placebo plus carboplatin and paclitaxel, followed by placebo.
Researchers observed a significant improvement in median overall survival with treatment vs placebo in the overall population — 44.6 vs 28.2 months, respectively (hazard ratio [HR], 0.69). Median progression-free survival was also significantly better in the treatment vs placebo group — 11.8 vs 7.9 months, respectively (HR, 0.64).
“Today’s expanded approval will offer even more patients the opportunity for improved outcomes,” Matthew Powell, MD, of Washington University School of Medicine, and principal investigator on the RUBY trial, said in a press release. “This is the only immuno-oncology treatment regimen that has shown a statistically significant overall survival benefit for the full patient population, which is a meaningful step forward in treating this challenging cancer.”
Adverse reactions occurring in at least 20% of patients receiving dostarlimab-gxly include anemia, increased creatinine levels, peripheral neuropathy, decreased white blood cell counts, fatigue, nausea, alopecia, low platelet counts, increased glucose levels, lymphopenia, neutropenia, liver function test abnormalities, arthralgia, rash, constipation, diarrhea, decreased albumin levels, abdominal pain, dyspnea, decreased appetite, increased amylase levels, urinary tract infection, and vomiting. Immune-mediated adverse reactions with dostarlimab-gxly were similar to those previously reported.
The recommended dostarlimab-gxly dose, according to the full prescribing information, is 500 mg every 3 weeks for six cycles administered before carboplatin and paclitaxel if given on the same day, followed by 1000 mg monotherapy every 6 weeks until disease progression or unacceptable toxicity, or up to 3 years.

The Last 30 Days: How Oncologists’ Choices Affect End-of-Life Cancer Care
TOPLINE:
Patients treated by oncologists in the top quartile for end-of-life prescribing behavior were almost four and a half times more likely to receive end-of-life therapy than those treated by these specialists in the bottom quartile.
METHODOLOGY:
- Researchers analyzed data from the Surveillance, Epidemiology, and End Results (SEER)-Medicare database, focusing on patients who died of cancer between 2012 and 2017.
- A total of 17,609 patients with breast, lung, colorectal, or prostate cancer were included, treated by 960 oncologists across 388 practices.
- Patients were required to have had at least one systemic cancer therapy claim in the last 180 days of life, with the treating oncologist identified on the basis of the therapy claim closest to the time of death.
- The study used multilevel models to estimate oncologists’ rates of providing cancer therapy in the last 30 days of life, adjusting for patient characteristics and practice variation.
- Functional status was assessed on the basis of paid claims for durable medical equipment in the last 60 months of life, with scores categorized as 0, 1, ≥ 2, or unknown.
TAKEAWAY:
- Oncologists in the 95th percentile for high end-of-life prescribing behavior had a 45% adjusted rate of treating patients in the last 30 days of life, compared with 17% among those in the 5th percentile.
- Patients treated by high end-of-life prescribing oncologists had over four times higher odds of receiving systemic therapy in the last 30 days of life (odds ratio [OR], 4.42; 95% CI, 4.00-4.89).
- Higher end-of-life prescribing oncologists also had a higher proportion of patients hospitalized in the last 30 days of life than low prescribers (58% vs 51.9%).
- No significant association was found between oncologist prescribing behavior and patient race or ethnicity, except for Black patients who had lower odds of receiving treatment (OR, 0.77; P < .001).
IN PRACTICE:
“Given calls to rein in overutilization of end-of-life six to eight cancer therapies, our findings highlight an underappreciated area for further research: How treatment discontinuation before death is shaped by oncologists’ unique treatment propensities. Elucidating the reasons for this remarkable variability in oncologist treatment behavior could inform efforts to reduce end-of-life cancer treatment overutilization,” wrote the authors of the study.
SOURCE:
The study was led by Login S. George, PhD, Institute for Health, Health Care Policy and Aging Research, Rutgers University in New Brunswick, New Jersey. It was published online in Cancer.
LIMITATIONS:
The study’s reliance on SEER-Medicare data may limit the generalizability of the findings to patients with Medicare Advantage, private insurance, or Medicaid, as well as younger patients. The lack of data on patient preferences and other health characteristics could confound the results. The study focused on systemic therapies and may not be generalizable to other treatments such as clinical trial drugs, oral therapies, surgery, or radiation. The data from 2012 to 2017 may not reflect more recent trends in cancer treatment.
DISCLOSURES:
The study was supported by grants from the National Cancer Institute and the Rutgers Cancer Institute of New Jersey. George disclosed receiving grants from these organizations. Additional disclosures are noted in the original article.

Ancient Viruses in Our DNA Hold Clues to Cancer Treatment
according to a fascinating new study in Science Advances. Targeting these viral remnants still lingering in our DNA could lead to more effective cancer treatment with fewer side effects, the researchers said.
The study “gives a better understanding of how gene regulation can be impacted by these ancient retroviral sequences,” said Dixie Mager, PhD, scientist emeritus at the Terry Fox Laboratory at the British Columbia Cancer Research Institute, Vancouver, British Columbia, Canada. (Mager was not involved in the study.)
Long thought to be “junk” DNA with no biologic function, “endogenous retroviruses,” which have mutated over time and lost their ability to create the virus, are now known to regulate genes — allowing some genes to turn on and off. Research in recent years suggests they may play a role in diseases like cancer.
But scientists weren’t exactly sure what that role was, said senior study author Edward Chuong, PhD, a genome biologist at the University of Colorado Boulder.
Most studies have looked at whether endogenous retroviruses code for proteins that influence cancer. But these ancient viral strands usually don’t code for proteins at all.
Dr. Chuong took a different approach. Inspired by scientists who’ve studied how viral remnants regulate positive processes (immunity, brain development, or placenta development), he and his team explored whether some might regulate genes that, once activated, help cancer thrive.
Borrowing from epigenomic analysis data (data on molecules that alter gene expression) for 21 cancers mapped by the Cancer Genome Atlas, the researchers identified 19 virus-derived DNA sequences that bind to regulatory proteins more in cancer cells than in healthy cells. All of these could potentially act as gene regulators that promote cancer.
The researchers homed in on one sequence, called LTR10, because it showed especially high activity in several cancers, including lung and colorectal cancer. This DNA segment comes from a virus that entered our ancestors’ genome 30 million years ago, and it’s activated in a third of colorectal cancers.
Using the gene editing technology clustered regularly interspaced short palindromic repeats (CRISPR), Dr. Chuong’s team silenced LTR10 in colorectal cancer cells, altering the gene sequence so it couldn’t bind to regulatory proteins. Doing so dampened the activity of nearby cancer-promoting genes.
“They still behaved like cancer cells,” Dr. Chuong said. But “it made the cancer cells more susceptible to radiation. That would imply that the presence of that viral ‘switch’ actually helped those cancer cells survive radiation therapy.”
Previously, two studies had found that viral regulators play a role in promoting two types of cancer: Leukemia and prostate cancer. The new study shows these two cases weren’t flukes. All 21 cancers they looked at had at least one of those 19 viral elements, presumably working as cancer enhancers.
The study also identified what activates LTR10 to make it promote cancer. The culprit is a regulator protein called mitogen-activated protein (MAP) kinase, which is overactivated in about 40% of all human cancers.
Some cancer drugs — MAP kinase inhibitors — already target MAP kinase, and they’re often the first ones prescribed when a patient is diagnosed with cancer, Dr. Chuong said. As with many cancer treatments, doctors don’t know why they work, just that they do.
“By understanding the mechanisms in the cell, we might be able to make them work better or further optimize their treatment,” he said.
“MAP kinase inhibitors are really like a sledgehammer to the cell,” Dr. Chuong said — meaning they affect many cellular processes, not just those related to cancer.
“If we’re able to say that these viral switches are what’s important, then that could potentially help us develop a more targeted therapy that uses something like CRISPR to silence these viral elements,” he said. Or it could help providers choose a MAP kinase inhibitor from among the dozens available best suited to treat an individual patient and avoid side effects.
Still, whether the findings translate to real cancer patients remains to be seen. “It’s very, very hard to go the final step of showing in a patient that these actually make a difference in the cancer,” Dr. Mager said.
More lab research, human trials, and at least a few years will be needed before this discovery could help treat cancer. “Directly targeting these elements as a therapy would be at least 5 years out,” Dr. Chuong said, “partly because that application would rely on CRISPR epigenome editing technology that is still being developed for clinical use.”

according to a fascinating new study in Science Advances. Targeting these viral remnants still lingering in our DNA could lead to more effective cancer treatment with fewer side effects, the researchers said.
The study “gives a better understanding of how gene regulation can be impacted by these ancient retroviral sequences,” said Dixie Mager, PhD, scientist emeritus at the Terry Fox Laboratory at the British Columbia Cancer Research Institute, Vancouver, British Columbia, Canada. (Mager was not involved in the study.)
Long thought to be “junk” DNA with no biologic function, “endogenous retroviruses,” which have mutated over time and lost their ability to create the virus, are now known to regulate genes — allowing some genes to turn on and off.

Transvaginal Ultrasound Often Misses Endometrial Cancer in Black Women
TOPLINE:
The transvaginal ultrasonography triage strategy is unreliable for diagnosing endometrial cancer in high-risk Black women, with a significant risk for false-negative results at different endometrial thickness thresholds.
METHODOLOGY:
- Poor performance of transvaginal ultrasonography-measured endometrial thickness as a diagnostic triage strategy for endometrial cancer may contribute to racial disparity in stage at diagnosis between Black and White women.
- Researchers assessed the false-negative probability using transvaginal ultrasonography-measured endometrial thickness thresholds as triage for endometrial cancer in 1494 Black women (median age, 46 years) who underwent hysterectomy.
- The researchers focused on endometrial thickness measurements recorded within 24 months before hysterectomy, as well as demographic and clinical data.
- The endometrial thickness thresholds were defined as < 3 mm, < 4 mm, and < 5 mm, with the rest grouped as ≥ 5 mm, consistent with guidelines.
- A total of 210 women had endometrial cancer. The most common presenting symptoms were fibroids (78%), vaginal bleeding (71%), and pelvic pain (57%).
TAKEAWAY:
- Twenty-four cases of endometrial cancer were below the 5-mm endometrial thickness threshold that would trigger biopsy, resulting overall in 11.4% of endometrial cancer cases potentially missed.
- The false-negative probability was 9.5% (20 cases) at the < 4-mm threshold and 3.8% (8 cases) at the < 3-mm threshold.
- Classic risk factors for endometrial cancer (postmenopausal bleeding, age ≥ 50 years, and BMI > 40) did not result in improved performance of the endometrial thickness triage strategy.
- False-negative probability was also similar among those with fibroids (12%) but higher in the setting of partial endometrial thickness visibility (26%) and pelvic pain (15%).
IN PRACTICE:
This study reveals a “concerning error rate for a triage strategy that would terminate further workup and provide false reassurance to both patients and physicians.” The results contribute to “an increasing body of work questioning the wisdom of the (transvaginal ultrasonography) triage strategy. It may be the case that the (transvaginal ultrasonography) triage for endometrial biopsy is no longer a preferred strategy in the setting of increasing endometrial cancer rates for all. For Black patients with concerning symptoms, tissue biopsy is recommended to avoid misdiagnosis of endometrial cancer,” the researchers concluded.
SOURCE:
The study, with first author Kemi M. Doll, MD, Fred Hutchinson Cancer Center, University of Washington, Seattle, was published online in JAMA Oncology.
LIMITATIONS:
The study did not include cases where transvaginal ultrasonography reports omitted endometrial thickness measurements or reported nonvisible endometrial thickness, possibly underestimating the failure rate of the transvaginal ultrasonography triage strategy.
The sample did not include endometrial cancer cases that were not treated with hysterectomy, which may occur in young women with grade 1 endometrial cancer, those medically incapable of undergoing surgery, and those with disease so advanced that surgery is no longer an option.
DISCLOSURES:
Funding was provided by Kuni Discovery Grants for Cancer Research: Advancing Innovation and by a grant from the National Institutes of Health. Dr. Doll reported receiving investigator-initiated research grants from the Patient Centered Outcomes Research Institute, American Association of Cancer Research, and Merck.
