Members of the United States military who served in Vietnam between 1961 and 1971 risked exposure to the weaponized chemical defoliant known as Agent Orange. Among the components of Agent Orange, benzene and tetrachlorodibenzo-p-dioxin (TCDD) are known carcinogens linked to several cancers. They include multiple myeloma, Hodgkin and non-Hodgkin lymphoma, as well as bladder, prostate, and lung cancer. 

In this ReCAP, Dr Timothy O'Brien, section chief of hematology at the Louis Stokes Cleveland VA Medical Center, examines the evidence that suggests a link between service-related Agent Orange exposure and acute myeloid leukemia (AML). He discusses preclinical models that show a relationship between benzene and TCDD exposure and the development of AML. 

Dr O'Brien also explains the factors that have limited researchers' ability to positively connect Agent Orange and AML. For example, there is a dwindling cohort of affected patients to study because dioxins can lie latent in fat cells for more than a decade, delaying the development of AML. During that time, many veterans will have died from unrelated causes. 

More research is needed for veterans to receive service-connected benefits for AML diagnoses. However, as Dr O'Brien notes, the PACT Act provides coverage for veterans who developed AML after exposure to benzene-contaminated water at Camp Lejeune.

All women, regardless of their risk profile, should consider prophylactic removal of the fallopian tubes at the same time as other pelvic surgery once they are finished having children, the Ovarian Cancer Research Alliance has advised.

The recommendation, announced Feb. 1, replaces the decades-old focus on symptom awareness and early detection and follows “sobering and deeply disappointing” results from a large U.K. study published 2 years ago, the organization said.

That was the UK Collaborative Trial of Ovarian Cancer Screening published in The Lancet in 2021, which followed more than 200,000 women for a median 16 years. It showed that screening average-risk women with a CA-125 blood test and ultrasound does not reduce deaths from the disease, as reported at the time by this news organization.

“We all hoped that the trial would show that early detection was effective in changing mortality rates. When the results came out, it was very hard to accept,” Audra Moran, OCRA president and CEO, said in an interview.

“We have an obligation to let people know that symptom awareness and early detection will not save lives” but considering opportunistic salpingectomy “absolutely will,” said Ms. Moran. Hence the renewed call for women to consider having their fallopian tubes removed.  

What sounds new about this call is that the group is directing fallopian tube removal to all women “who are undergoing pelvic surgeries for benign conditions,” irrespective of what perceived risk they have of developing ovarian cancer (for example, based on family history).

But this advice has been in place for years for women who are known to be at higher risk for the disease.

For instance, women at high risk for ovarian cancer based on Hereditary Breast and Ovarian Cancer Syndrome (HBOC) have long been recommended to undergo surgery to remove ovaries and fallopian tubes (risk-reducing bilateral salpingo-oophorectomy or RRBSO) once there is no longer a desire for pregnancy.

Approached for comment about the new messaging, Stephanie V. Blank, MD, president of the Society of Gynecologic Oncology, says that the new recommendation – that all women who are finished childbearing consider opportunistic salpingectomy at the time of other pelvic surgery for benign conditions – is “not aggressive.”

“It’s reasonable and makes sense,” Dr. Blank said in an interview.

And she pointed out that it’s actually not “new”; it is, however, getting “new attention” based on the disappointing U.K. screening study, said Dr. Blank, director of gynecologic oncology for the Mount Sinai Health System in New York and professor of gynecologic oncology at Icahn School of Medicine at Mount Sinai.

She noted that the procedure of opportunistic salpingectomy has been endorsed by SGO since 2013 and by the American College of Obstetricians and Gynecologists since 2015.

There is increasing evidence that most high-grade serous ovarian cancers arise from cells in the fallopian tubes, William Dahut, MD, chief scientific officer for the American Cancer Society, told this news organization.

“Indirect evidence suggests a fairly strong degree of risk reduction associated with opportunistic salpingectomy for the most prevalent type of ovarian cancer (serous), and some risk reduction of epithelial ovarian cancer. At this time, these discussions seem warranted,” Dr. Dahut said.

At this point, however, the fact that leading organizations advise “consideration” means that the evidence base has “not been judged to be sufficiently strong (in terms of what we can say about benefits and harms) to advise a direct recommendation for opportunistic salpingectomy,” Dr. Dahut added.

There is no current recommendation to have fallopian tubes removed as a stand-alone procedure, he pointed out. However, he commented that “the occasion of scheduled gynecologic surgery presents an opportunity to possibly reduce the risk of ovarian cancer without known adverse effects in women who have completed childbearing. Having the discussion seems to be justified by the current evidence,” Dr. Dahut said.

Deanna Gerber, MD, a gynecologic oncologist at NYU Langone Perlmutter Cancer Center-Long Island, agrees. “In women who are scheduled to have a gynecologic or pelvic procedure, clinicians should discuss the possibility of removing the fallopian tubes at that time. A salpingectomy is a relatively low-risk procedure and adds little time to the surgery,” Dr. Gerber said in an interview.

“Women should understand that there is still ongoing research on this topic, but this low-risk procedure may reduce their risk of developing an ovarian or fallopian tube cancer,” Dr. Gerber said.

OCRA also encourages all women (or anyone born with ovaries) to know their risk for ovarian cancer. To that end, the organization has launched a pilot program offering free, at-home genetic testing kits to people with a personal or family history of breast, ovarian, uterine, or colorectal cancer.

Ms. Moran, Dr. Blank, Dr. Dahut, and Dr. Gerber report no relevant financial relationships.

San Diego – Despite advances in dermoscopy and other techniques for diagnosing cutaneous melanoma, histology remains the gold standard.

“I don’t think that’s going to change in the short term,” Travis W. Blalock, MD, director of dermatologic surgery, Mohs micrographic surgery, and cutaneous oncology at Emory University, Atlanta, said at the annual Cutaneous Malignancy Update. “But I do think we can supplement that with other modalities that will improve the clinical examination and help dermatopathologists as they assess and evaluate these lesions,” he said, adding: “The reality is, histopathology, while it may be the gold standard, is not necessarily a consistently reproducible evaluation. That raises the question: What can we do better?”

According to Dr. Blalock, the future may include more routine use of noninvasive genetic molecular assays to assist with the diagnostics challenges linked to the visual image and pattern recognition approach of detecting cutaneous melanoma. For example, a two-gene classification method based on LINC00518 and preferentially expressed antigen in melanoma (PRAME) gene expression was evaluated and validated in 555 pigmented lesions obtained noninvasively via adhesive patch biopsy.

“Today, you can pick up a kit from your local pharmacy that can tell you a bit about broad genetic susceptibilities,” he said at the meeting, which was hosted by Scripps MD Anderson Cancer Center. He predicted that using adhesive patch biopsies to assess suspicious melanocytic lesions “is likely the wave of the future.” This may increase patient understanding “as to the types of risks they have, the different lesions they have, and minimize invasive disease, but it also will pose different challenges for us when it comes to deploying patient-centered health care. For example, in a patient with multiple different lesions, how are you going to keep track of them all?”

Dermoscopy

In Dr. Blalock’s clinical opinion, dermoscopy improves the sensitivity of human visual detection of melanoma and may allow detection before a lesion displays classical features described with the “ABCDE rule.” However, the learning curve for dermoscopy is steep, he added, and whether the technique should be considered a first-line tool or as a supplement to other methods of examining cutaneous lesions remains a matter of debate.

“Dermoscopy is our version of the stethoscope,” he said. “We need to figure out when we’re going to use it. Should we be using it all of the time or only some of the time? Based on the clinical setting, maybe it’s a personal choice, but this can be a helpful skill and art in your practice if you’re willing to take the time to learn.”

In 2007, the International Dermoscopy Society (IDS) established a proposal for the standardization and recommended criteria necessary to effectively convey dermoscopic findings to consulting physicians and colleagues. The document includes 10 points categorized as either recommended or optional for a standardized dermoscopy report.

“The first step is to assess the lesion to determine whether or not it’s melanocytic in the first place,” said Dr. Blalock. “There are many different features – the mile-high [global features] evaluation of the lesions – then more specific local features that may clue you in to specific diagnoses,” he noted. “Once we get past that first step of determining that a lesion is melanocytic, it’s not enough to stop there, because we don’t want to biopsy every single lesion that’s melanocytic,” so there is a need to determine which ones require intervention, which is where dermoscopy “gets trickier and a little more challenging.”

According to the IDS, a standard dermoscopy report should include the patient’s age, relevant history pertaining to the lesion, pertinent personal and family history (recommended); clinical description of the lesion (recommended); the two-step method of dermoscopy differentiating melanocytic from nonmelanocytic tumors (recommended); and the use of standardized terms to describe structures as defined by the Dermoscopy Consensus Report published in 2003.

For new terms, the document states, “it would be helpful” for the physician to provide a working definition (recommended); the dermoscopic algorithm used should be mentioned (optional); information on the imaging equipment and magnification (recommended); clinical and dermoscopic images of the tumor (recommended); a diagnosis or differential diagnosis (recommended); decision concerning management (recommended), and specific comments for the pathologist when excision and histopathologic examination are recommended (optional).

The 2007 IDS document also includes a proposed seven-point checklist to differentiate between benign and melanocytic lesions on dermoscopy. Three major criteria are worth two points each: The presence of an atypical pigment network, gray-blue areas (commonly known as the veil), and an atypical vascular pattern. Four minor criteria are worth one point each: Irregular streaks, irregular dots/globules, irregular pigmentation, and regression structures. A minimum total score of 3 is required to establish a diagnosis of melanoma.

Another diagnostic technique, digital mole mapping, involves the use of photography to detect new or changing lesions. Dr. Blalock described this approach as rife with limitations, including variations in quality, challenges of storing and maintaining records, cost, time required to evaluate them, and determining which patients are appropriate candidates.

Other techniques being evaluated include computer algorithms to help dermatologists determine the diagnosis of melanoma from dermoscopic images, electrical impedance spectroscopy for noninvasive evaluation of atypical pigmented lesions, and ultrasound for staging of cutaneous malignant tumors.

Ultimately, “I think we’ll have multiple tools in our belt,” Dr. Blalock said, adding, “How do we pull them out at the right time to improve the lives of our patients? Are we going to use ultrasound? Dermoscopy? Integrate them with some of the genetic findings?”

Dr. Blalock disclosed that he has served as a principal investigator for Castle Biosciences.

Other techniques being evaluated include computer algorithms to help dermatologists determine the diagnosis of melanoma from dermoscopic images, electrical impedance spectroscopy for noninvasive evaluation of atypical pigmented lesions, and ultrasound for staging of cutaneous malignant tumors.

Ultimately, “I think we’ll have multiple tools in our belt,” Dr. Blalock said, adding, “How do we pull them out at the right time to improve the lives of our patients? Are we going to use ultrasound? Dermoscopy? Integrate them with some of the genetic findings?”

Dr. Blalock disclosed that he has served as a principal investigator for Castle Biosciences.

A 27-gene immuno-oncology assay appears to provide useful information about whether patients with advanced non–small cell lung cancer (NSCLC) could benefit from immune checkpoint inhibitor (ICI) therapy despite their poor status, researchers reported.

Positive findings on the test, known as DetermaIO, were “associated with efficacy of response to ICI therapy in advanced NSCLC patients,” Matthew G. Varga, PhD, manager of scientific affairs at Oncocyte, said in an interview. “These data suggest that DetermaIO warrants further study in poor performance status patients as it has the potential to identify likely responders to ICI therapy.”

Oncocyte, which is developing the test, presented the findings in a poster at the annual meeting of the Society for Immunotherapy of Cancer.

According to Dr. Varga, “DetermaIO is an RT-qPCR test that can be applied to FFPE [formalin-fixed, paraffin-embedded] tissue specimens to quantify the relative gene expression of 27 genes and subsequently applies our proprietary algorithm to generate an IO score based on the gene expression profile. The DetermaIO score is a binary IO+ or IO– score, representing likely responder or nonresponder, respectively.”

The test was originally developed for triple negative breast cancer, Dr. Varga said, and it’s been validated in non–small cell lung cancer, metastatic urothelial carcinoma, and metastatic colorectal carcinoma.

For the study, the researchers retrospectively tracked associations between DetermaIO score and either progression-free survival (PFS) or overall survival (OS) in 147 patients in Canada with NSCLC who were treated with ICI monotherapy. All had programmed death-ligand 1 (PD-L1) ≥ 50%.

Overall, outcomes were poor: The median survival was 12.7 months, and median PFS was 7.0 months. These outcomes were even worse in those who underwent therapy as a second- line treatment: The median survival was 9.7 months, and median PFS was 4.4 months.

“DetermaIO was significantly associated with PFS at hazard ratio [HR] = 0.55, 95% [confidence interval] CI, 0.32-0.94, P = .028. In our analyses, a hazard ratio less than 1 suggests lower risk – i.e, that DetermaIO+ patients have lower risk of an event – death or progression – compared to a DetermaIO– patient,” Dr. Varga said. “The association for overall survival was not statistically significant, but it was suggestive of clinically meaningful benefit.”

He added that “we could identify likely responders from nonresponders, suggesting that the DetermaIO score adds both independent and incremental data to the existing gold standard biomarker. The objective response rate for all first-line patients – n = 78 – was 44.9%. Twenty-two DetermaIO– tumors had a 23% response rate (5 partial responses) whereas of the 56 DetermaIO+ patients, the response rate was 54% (2 complete response and 28 partial responses).”

A score on the test, he said, was not associated with OS or PFS in patients who received second-line or later treatment.

The study was not designed to evaluate the predictive power of the test. “For a biomarker to be defined as predictive requires a formal test of interaction between a treatment group (ICI monotherapy, for example) vs. a control group (chemo-only or other regimen),” Dr. Varga explained. “In our analysis, there was no group of patients who did not receive ICI monotherapy. Thus a test for interaction and a predictive claim cannot be made.”

The test is available for at no cost via an early access program, Dr. Varga said, and Oncocyte is getting ready to seek Medicare coverage. The ultimate cost of the test, he said, is unknown.

Long-course radiation therapy for rectal cancer is more likely to spare organs than short-course therapy, including when chemotherapy is provided first as part of a total neoadjuvant therapy (TNT) strategy, shows new research presented at the ASCO Gastrointestinal Cancers Symposium 2023.

“When we looked at the 2-year organ preservation rates, they were numerically higher in the long-course group versus the short-course group,” said study author J. Joshua Smith, MD, PhD,FACS, a colorectal surgeon with Memorial Sloan Kettering Cancer Center, New York. “Our study will be the first, to our knowledge, that examines a significant proportion of patients treated with the induction total neoadjuvant therapy approach – chemo first.”

An ideal outcome in rectal cancer is no need for surgery, Dr. Smith said. “If you can avoid surgery altogether and preserve the organ [the rectum], that’s a big win for the patient as they are usually able to avoid having a permanent or temporary ostomy.”

Long-course and short-course radiation have similar outcomes in terms of patients going on to need surgery, but it’s not clear which is superior in terms of organ sparing, toxicity, and side effects, said Paul Romesser, MD, a radiation oncologist with Memorial Sloan Kettering Cancer Center, New York, who served as first author of the study.

During the early months of the COVID-19 pandemic, the cancer center embraced short-course radiation in rectal cancer, Dr. Romesser said. “Once we emerged from the cloud of COVID, we said: ‘Well, what do we do now? Where do we go? Do we go back to what we did before? Or, do we go stick with the same? And what does that mean for organ preservation?’ ”

The researchers retrospectively identified 563 consecutive patients treated with TNT from 2018 to 2021. They focused on 332 who didn’t have metastatic disease, synchronous/metachronous malignancies, or nonadenocarcinoma histology (long course = 256, short course = 76). The groups had similar high-risk features, and about 82% were clinical stage III).

Patients most commonly received induction chemotherapy followed by consolidative radiation (78% long course, 70% short course).

The 2-year survival rates were similar, but organ preservation was higher in the long-course group versus the short-course group (40%; 95% confidence interval, 35%-47% vs. 29%; 95% CI, 20%-42%). And the 2-year local regrowth rate was also better in the long-course group versus the short-course group (20%; 95% CI, 12%-27% vs. 36%; 95% CI, 16%-52%).

Why might long-course therapy be better? “It’s probably just coming down to the biologically equivalent dose,” which is likely lower in short-course radiation, Dr. Romesser said.

Going forward, Dr. Romesser said he’ll tell patients about the findings of this study and a previous report published in 2022 that determined that “organ preservation is achievable in half of the patients with rectal cancer treated with total neoadjuvant therapy, without an apparent detriment in survival, compared with historical controls treated with chemoradiotherapy, TME [total mesorectal excision], and postoperative chemotherapy.” Dr. Smith is a coauthor of that study.

“Generally, I’ll steer patients toward long course, assuming all else is equal, and it’s not an undue burden on them financially and socially to come in for 5-6 weeks of chemoradiation,” Dr. Romesser said. He added that, “generally, the insurance companies recognize [short-course and long-course radiation] as both acceptable and standard treatment options for patients. We haven’t found that insurances will approve one, but not the other.”

The study was funded by the National Institutes of Health. Dr. Romesser disclosed consulting/advisory roles (EMD Serono, Faeth, Natera), research funding (XRad), and travel/accommodations/expenses (Elekta). Dr. Smith disclosed consulting/advisory roles (Foundation Medicine, Guardant Health). The other study authors reported no conflicts of interest.

A pair of new studies suggest limitations of adjuvant chemotherapy among older adults with stage 3 colorectal cancer. A phase 2, multi-institutional feasibility study found a completion rate of 67.3%, while a prospective study found that completion was associated with improved disease-free survival.

Both studies were presented in January at the ASCO Gastrointestinal Cancers Symposium 2023.

In HiSCO-04, Japanese researchers found that of 64 older patients with stage 3A colorectal cancer who underwent adjuvant chemotherapy, 53% completed the treatment with an improvement in disease-free survival. Patients who completed adjuvant chemotherapy had better disease-free survival (P = .03), while the survival was lower among those who did not receive adjuvant chemotherapy, and lowest among those who discontinued adjuvant chemotherapy.

“The results showed that adjuvant chemotherapy is not always recommended for elderly patients, and that patients who are able to complete treatment may have a better prognosis for survival. However, the results do not indicate which patients are unable to complete chemotherapy, and it will be necessary to identify patients who are intolerant of chemotherapy,” said the study’s lead author Manabu Shimomura, MD, PhD, an assistant professor of gastroenterological and transplant surgery at the Hiroshima University Graduate School of Biomedical and Health Sciences in Japan.

The study, which was conducted between 2013 and 2021, enrolled 214 patients (99 men, 115 women, 80-101 years old) who were in stage 3 cancer (27 cases 3A, 158 cases 3B, and 29 cases 3C). A total of 41 patients were ineligible for chemotherapy. Of the remaining patients, 65 received adjuvant chemotherapy and 108 did not receive adjuvant chemotherapy.

The 3-year disease-free survival was 63.6%, the 3-year overall survival was 76.9%, and the 3-year relapse-free survival was 63.1%. Thirty-six patients died because of colorectal cancer, and 30 patients died of other causes. There was recurrence in 58 cases and secondary cancers were observed in 17 cases during the 42.5 months–long follow-up period.

There were few reports of serious adverse events, but some cases of treatment discontinuation were because of adverse events.

In a second study presented by Dr. Shimomura’s group, called HiSCO-03, 65 patients (33 female) underwent curative resection and received five courses of uracil-tegafur and leucovorin (UFT/LV).

The completion rate of 67.3% had a 95% lower bound of 54.9%, which were lower than the predefined thresholds of 75% completion and a lower bound of 60%. “Based on the results of a previous (ACTS-CC phase III) study, we set the expected value of UFT/LV therapy in patients over 80 years of age at 75% and the threshold at 60%. Since the target age group of previous study was 75 years or younger, we concluded from the results of the current study that UFT/LV therapy is less well tolerated in patients 80 years of age and older than in patients 75 years of age and younger,” Dr. Shimomura said.

The treatment completion rate trended higher in males than females (77.6% versus 57.2%; P = .06) and performance status of 0 versus 1 or 2 (74.3% versus 58.9%; P = .10). The most common adverse events were anorexia (33.8%), diarrhea (30.8%), and anemia (24.6%). The median relative dose intensity was 84% for UFT and 100% for LV.

The challenges of treating older patients

If and how older patients with colorectal cancer should be treated is not clear cut. While 20% of patients in the United States who have colorectal cancer are over 80 years old, each case should be evaluated individually, experts say.

Writing in a 2015 review of colorectal cancer treatment in older adults, Monica Millan, MD, PhD, of Joan XXIII University Hospital, Tarragona, Spain, and colleagues, wrote that physiological heterogeneity and coexisting medical conditions make treating older patients with colorectal cancer challenging.

“Age in itself should not be an exclusion criterion for radical treatment, but there will be many elderly patients that will not tolerate or respond well to standard therapies. These patients need to be properly assessed before proposing treatment, and a tailored, individualized approach should be offered in a multidisciplinary setting,” wrote Dr. Millan, who is a colorectal surgeon.

The authors suggest that older patients who are fit could be treated similarly to younger patients, but there remain uncertainties about how to proceed in frail older adults with comorbidities.

“Most elderly patients with cancer will have priorities besides simply prolonging their lives. Surveys have found that their top concerns include avoiding suffering, strengthening relationships with family and friends, being mentally aware, not being a burden on others, and achieving a sense that their life is complete. The treatment plan should be comprehensive: cancer-specific treatment, symptom-specific treatment, supportive treatment modalities, and end-of-life care,” they wrote.

The U.S. Preventive Services Task Force recommends colorectal cancer screening for men and women who are between 45 and 75 years old; however, screening for patients between 76 and 85 years old should be done on a case-by-case basis based on a patient’s overall health, screening history, and the patient’s preferences.

Colorectal cancer incidence rates have been declining since the mid-1980s because of an increase in screening among adults 50 years and older, according to the American Cancer Society. Likewise, mortality rates have dropped from 29.2% in 1970 to 12.6% in 2020 – mostly because of screening.

Dr. Shimomura has no relevant financial disclosures.

The most common adverse events were anorexia (33.8%), diarrhea (30.8%), and anemia (24.6%). The median relative dose intensity was 84% for UFT and 100% for LV.

The challenges of treating older patients

If and how older patients with colorectal cancer should be treated is not clear cut. While 20% of patients in the United States who have colorectal cancer are over 80 years old, each case should be evaluated individually, experts say.

Writing in a 2015 review of colorectal cancer treatment in older adults, Monica Millan, MD, PhD, of Joan XXIII University Hospital, Tarragona, Spain, and colleagues, wrote that physiological heterogeneity and coexisting medical conditions make treating older patients with colorectal cancer challenging.

“Age in itself should not be an exclusion criterion for radical treatment, but there will be many elderly patients that will not tolerate or respond well to standard therapies. These patients need to be properly assessed before proposing treatment, and a tailored, individualized approach should be offered in a multidisciplinary setting,” wrote Dr. Millan, who is a colorectal surgeon.

The authors suggest that older patients who are fit could be treated similarly to younger patients, but there remain uncertainties about how to proceed in frail older adults with comorbidities.

“Most elderly patients with cancer will have priorities besides simply prolonging their lives. Surveys have found that their top concerns include avoiding suffering, strengthening relationships with family and friends, being mentally aware, not being a burden on others, and achieving a sense that their life is complete. The treatment plan should be comprehensive: cancer-specific treatment, symptom-specific treatment, supportive treatment modalities, and end-of-life care,” they wrote.

The U.S. Preventive Services Task Force recommends colorectal cancer screening for men and women who are between 45 and 75 years old; however, screening for patients between 76 and 85 years old should be done on a case-by-case basis based on a patient’s overall health, screening history, and the patient’s preferences.

Colorectal cancer incidence rates have been declining since the mid-1980s because of an increase in screening among adults 50 years and older, according to the American Cancer Society. Likewise, mortality rates have dropped from 29.2% in 1970 to 12.6% in 2020 – mostly because of screening.

A pair of new studies suggest limitations of adjuvant chemotherapy among older adults with stage 3 colorectal cancer. A phase 2, multi-institutional feasibility study found a completion rate of 67.3%, while a prospective study found that completion was associated with improved disease-free survival.

Both studies were presented in January at the ASCO Gastrointestinal Cancers Symposium 2023.

In HiSCO-04, Japanese researchers found that of 64 older patients with stage 3A colorectal cancer who underwent adjuvant chemotherapy, 53% completed the treatment with an improvement in disease-free survival. Patients who completed adjuvant chemotherapy had better disease-free survival (P = .03), while the survival was lower among those who did not receive adjuvant chemotherapy, and lowest among those who discontinued adjuvant chemotherapy.

“The results showed that adjuvant chemotherapy is not always recommended for elderly patients, and that patients who are able to complete treatment may have a better prognosis for survival. However, the results do not indicate which patients are unable to complete chemotherapy, and it will be necessary to identify patients who are intolerant of chemotherapy,” said the study’s lead author Manabu Shimomura, MD, PhD, an assistant professor of gastroenterological and transplant surgery at the Hiroshima University Graduate School of Biomedical and Health Sciences in Japan.

The study, which was conducted between 2013 and 2021, enrolled 214 patients (99 men, 115 women, 80-101 years old) who were in stage 3 cancer (27 cases 3A, 158 cases 3B, and 29 cases 3C). A total of 41 patients were ineligible for chemotherapy. Of the remaining patients, 65 received adjuvant chemotherapy and 108 did not receive adjuvant chemotherapy.

The 3-year disease-free survival was 63.6%, the 3-year overall survival was 76.9%, and the 3-year relapse-free survival was 63.1%. Thirty-six patients died because of colorectal cancer, and 30 patients died of other causes. There was recurrence in 58 cases and secondary cancers were observed in 17 cases during the 42.5 months–long follow-up period.

There were few reports of serious adverse events, but some cases of treatment discontinuation were because of adverse events.

In a second study presented by Dr. Shimomura’s group, called HiSCO-03, 65 patients (33 female) underwent curative resection and received five courses of uracil-tegafur and leucovorin (UFT/LV).

The completion rate of 67.3% had a 95% lower bound of 54.9%, which were lower than the predefined thresholds of 75% completion and a lower bound of 60%. “Based on the results of a previous (ACTS-CC phase III) study, we set the expected value of UFT/LV therapy in patients over 80 years of age at 75% and the threshold at 60%. Since the target age group of previous study was 75 years or younger, we concluded from the results of the current study that UFT/LV therapy is less well tolerated in patients 80 years of age and older than in patients 75 years of age and younger,” Dr. Shimomura said.

The treatment completion rate trended higher in males than females (77.6% versus 57.2%; P = .06) and performance status of 0 versus 1 or 2 (74.3% versus 58.9%; P = .10). The most common adverse events were anorexia (33.8%), diarrhea (30.8%), and anemia (24.6%). The median relative dose intensity was 84% for UFT and 100% for LV.

The Food and Drug Administration approved a new indication for sacituzumab govitecan (Trodelvy, Gilead Sciences) on Feb. 3 for patients with unresectable, locally advanced or metastatic hormone receptor (HR)–positive, HER2-negative breast cancer after endocrine-based therapy and at least two additional systemic therapies for metastatic disease.

Label expansion for the Trop-2–directed antibody-drug conjugate was based on the TROPICS-02 trial, which randomized 543 adults 1:1 to either sacituzumab govitecan 10 mg/kg IV on days 1 and 8 of a 21-day cycle or single agent chemotherapy, most often eribulin but also vinorelbine, gemcitabine, or capecitabine.

Median progression free survival was 5.5 months with sacituzumab govitecan versus 4 months with single agent chemotherapy (hazard ratio, 0.66; P = .0003). Median overall survival was 14.4 months in the sacituzumab govitecan group versus 11.2 months with chemotherapy (HR, 0.79), according to an FDA press release announcing the approval.

In a Gilead press release, Hope Rugo, MD, a breast cancer specialist at the University of California, San Francisco, and principal investigator for TROPICS-02, said the approval “is significant for the breast cancer community. We have had limited options to offer patients after endocrine-based therapy and chemotherapy, and to see a clinically meaningful survival benefit of more than 3 months with a quality-of-life benefit for these women is exceptional.”

The most common adverse events associated with sacituzumab govitecan in the trial, occurring in a quarter or more of participants, were decreased leukocyte count, decreased neutrophil count, decreased hemoglobin, decreased lymphocyte count, diarrhea, fatigue, nausea, alopecia, glucose elevation, constipation, and decreased albumin.

Labeling for the agent carries a boxedwarning of severe or life-threatening neutropenia and severe diarrhea.

The recommended dose is the trial dose: 10 mg/kg IV on days 1 and 8 of 21-day cycles until disease progression or unacceptable toxicity.

Sacituzumab govitecan was previously approved for unresectable, locally advanced or metastatic triple-negative breast cancer after two or more prior systemic therapies and locally advanced or metastatic urothelial cancer after platinum-based chemotherapy and either a PD-1 or PD-L1 inhibitor.

Both race and place of residence affect how soon a woman in North Carolina receives treatment for breast cancer, suggesting the need to target high-risk geographic regions and patient groups to ensure timely care, new research suggests.

Among nearly 33,000 women from North Carolina with stage I-III breast cancer, Black patients were nearly twice as likely has non-Black patients to experience treatment delays of more than 60 days, researchers found.

“Our findings suggest that treatment delays are alarmingly common in patients at high risk for breast cancer death, including young Black women and patients with stage III disease,” the authors note in their article, which was published online in Cancer.

Research shows that breast cancer treatment delays of 30-60 days can lower survival, and Black patients face a “disproportionate risk of treatment delays across the breast cancer care delivery spectrum,” the authors explain.

However, studies exploring whether or how racial disparities in treatment delays relate to geography are more limited.

In the current analysis, researchers amassed a retrospective cohort of all patients with stage I-III breast cancer between 2004 and 2015 in the North Carolina Central Cancer Registry and explored the risk of treatment delay by race and geographic subregion.

The cohort included 32,626 women, 6,190 (19.0%) of whom were Black. Counties were divided into the nine Area Health Education Center regions for North Carolina.

Compared with non‐Black patients, Black patients were more likely to have stage III disease (15.2% vs. 9.3%), hormone receptor–negative tumors (29.3% vs. 15.6%), Medicaid insurance (46.7% vs. 14.9%), and to live within 5 miles of their treatment site (30.6% vs. 25.2%).

Overall, Black patients were almost two times more likely to experience a treatment delay of more than 60 days (15% vs. 8%).

On average, about one in seven Black women experienced a lengthy delay, but the risk varied depending on geographic location. Patients living in certain regions of the state were more likely to experience delays; those in the highest-risk region were about twice as likely to experience a delay as those in the lowest-risk region (relative risk, 2.1 among Black patients; and RR, 1.9 among non-Black patients).

The magnitude of the racial gap in treatment delay varied by region – from 0% to 9.4%. But overall, of patients who experienced treatment delays, a significantly greater proportion were Black patients in every region except region 2, where only 2.7% (93 of 3,362) of patients were Black.

Notably, two regions with the greatest disparities in treatment delay, as well as the highest absolute risk of treatment delay for Black patients, surround large cities.

“These delays weren’t explained by the patients’ distance from cancer treatment facilities, their specific stage of cancer or type of treatment, or what insurance they had,” lead author Katherine Reeder-Hayes, MD, with the University of North Carolina Lineberger Comprehensive Cancer Center, Chapel Hill, said in a news release.

Instead, Dr. Reeder-Hayes said, the findings suggest that the structure of local health care systems, rather than patient characteristics, may better explain why some patients experience treatment delays.

In other words, “if cancer care teams in certain areas say, ‘Oh, it’s particularly hard to treat breast cancer in our area because people are poor or have really advanced stages of cancer when they come in,’ our research does not bear out that explanation,” Dr. Reeder-Hayes said in email to this news organization.

This study “highlights the persistent disparities in treatment delays Black women encounter, which often lead to worse outcomes,” said Kathie-Ann Joseph, MD, MPH, who was not involved in the research.

“Interestingly, the authors could not attribute these delays in treatment to patient-level factors,” said Dr. Joseph, a breast cancer surgeon at NYU Langone Perlmutter Cancer Center, New York. But the authors “did find substantial geographic variation, which suggests the need to address structural barriers contributing to treatment delays in Black women.”

Sara P. Cate, MD, who was not involved with the research, also noted that the study highlights a known issue – “that racial minorities have longer delays in cancer treatment.” And notably, she said, the findings reveal that this disparity persists in areas where access to care is better and more robust.

“The nuances of the delays to care are multifactorial,” said Dr. Cate, a breast cancer surgeon and director of the Breast Surgery Quality Program at Mount Sinai in New York. “We need to do better with this population, and it is a multilevel solution of financial assistance, social work, and patient navigation.”

The study was supported in part by grants from the Susan G. Komen Foundation and the NC State Employees’ Credit Union. Dr. Reeder-Hayes, Dr. Cate, and Dr. Joseph have disclosed no relevant financial relationships.

While it’s well known that COVID-19 vaccines are less effective in patients with chronic lymphocytic leukemia (CLL) who take immunity-lowering drugs, a new study offers fresh insight into what’s happening inside the body. In these patients, the vaccines often don’t boost B cells, which produce antibodies, but they do strengthen T cells, potentially providing crucial protection against severe illness and death.

These findings don’t reveal whether the T-cell boost actually provides extra protection against COVID-19. Still, the study suggests that patients with CLL should be vaccinated no matter which medications they’re taking, coauthor and hematologist/oncologist Clemens-Martin Wendtner, MD, of the Munich (Germany) Clinic, said in an interview.

“Do not defer or pause treatment,” said Dr. Wendtner, whose study was published in Blood Advances.

Patients with CLL appear to have among the weakest responses to the COVID-19 vaccine among people with various types of blood cancer. A meta-analysis published in 2022 found that seropositivity rates following vaccination were just 51% in patients with CLL, compared with 80%-90% in those with acute leukemia and 76%-80% of those with myeloma.

“Usually, the response rate to vaccination among the nonimmunocompromised would be 95%,” Dr. Wendtner said.

Research has also suggested that patients treated with B-cell pathway inhibitors and anti-CD20 antibodies are especially likely to have poorer responses to COVID-19 vaccines, no surprise considering that their job is to dampen the immune system. But there’s an unanswered question, according to Dr. Wendtner: Does “just measuring B-cell response tell us everything about the immune response?”

The new prospective, single-institution study aims to answer that question in patients who each received two types of vaccines. Researchers compared peripheral blood mononuclear cell transcriptional response with antibody and T-cell response rates in 15 patients with CLL/small lymphocytic lymphoma following vaccination with both the Pfizer-BioNTech and AstraZeneca vaccines.

The average antibody response was limited. “Overall, 7/15 of patients failed to mount a humoral response even after three-dose vaccination,” the researchers reported. All of the patients were “heavily pretreated” with CLL medications such as venetoclax, an anti-CD20 monoclonal antibody.

By contrast, the T-cell response was much stronger: 80% of patients (12/15) had a robust response, a number that grew to 90% (14/15) after a booster. This response is “almost ideal” considering that the response in a nonimmunocompromised person would be about 99%, Dr. Wendtner said.

The study also revealed that vaccine responses were weaker in patients who took a combination of a Bruton tyrosine kinase inhibitor and venetoclax within a year.

Four patients developed COVID-19 infections with the Omicron variant about 6 months after vaccination. All had mild symptoms. A lone patient had a history of COVID-19 infection prior to vaccination.

The researchers noted that the study had several limitations, including its small size, its reliance on a single institution, and the differences in treatments and vaccination protocols among the patient population.

Broadly speaking, the study showed that “a vaccine is not in vain” in patients with CLL, “although the doctor might not detect an antibody response,” Dr. Wendtner said. He added that mixing vaccine types should provide more protection. Start with a viral vector vaccine followed by an mRNA vaccine or vice versa, he suggested.

In an interview, infectious disease physician Joshua A. Hill, MD, from Fred Hutchinson Cancer Center, Seattle, who wasn’t involved with the study, said it makes “important and interesting observations to reinforce other studies with similar findings.”

Specifically, Dr. Hill said, “despite the absence of a robust antibody response some of these patients who are on active treatment, patients can still generate robust cellular immune responses in the form of T-cell immunity. Our understanding is that having T cell immunity will provide important additional protection for developing severe disease, although is less easily tested.”

As for the best vaccination strategies, Dr. Hill said “patients should get vaccinated as soon as they are eligible, according to standard guidelines. If patients have not yet started therapy, they should get their indicated vaccines before starting treatment whenever possible.”

While it’s well known that COVID-19 vaccines are less effective in patients with chronic lymphocytic leukemia (CLL) who take immunity-lowering drugs, a new study offers fresh insight into what’s happening inside the body. In these patients, the vaccines often don’t boost B cells, which produce antibodies, but they do strengthen T cells, potentially providing crucial protection against severe illness and death.

These findings don’t reveal whether the T-cell boost actually provides extra protection against COVID-19. Still, the study suggests that patients with CLL should be vaccinated no matter which medications they’re taking, coauthor and hematologist/oncologist Clemens-Martin Wendtner, MD, of the Munich (Germany) Clinic, said in an interview.

“Do not defer or pause treatment,” said Dr. Wendtner, whose study was published in Blood Advances.

Patients with CLL appear to have among the weakest responses to the COVID-19 vaccine among people with various types of blood cancer. A meta-analysis published in 2022 found that seropositivity rates following vaccination were just 51% in patients with CLL, compared with 80%-90% in those with acute leukemia and 76%-80% of those with myeloma.

“Usually, the response rate to vaccination among the nonimmunocompromised would be 95%,” Dr. Wendtner said.

Research has also suggested that patients treated with B-cell pathway inhibitors and anti-CD20 antibodies are especially likely to have poorer responses to COVID-19 vaccines, no surprise considering that their job is to dampen the immune system. But there’s an unanswered question, according to Dr. Wendtner: Does “just measuring B-cell response tell us everything about the immune response?”

The new prospective, single-institution study aims to answer that question in patients who each received two types of vaccines. Researchers compared peripheral blood mononuclear cell transcriptional response with antibody and T-cell response rates in 15 patients with CLL/small lymphocytic lymphoma following vaccination with both the Pfizer-BioNTech and AstraZeneca vaccines.

The average antibody response was limited. “Overall, 7/15 of patients failed to mount a humoral response even after three-dose vaccination,” the researchers reported. All of the patients were “heavily pretreated” with CLL medications such as venetoclax, an anti-CD20 monoclonal antibody.

By contrast, the T-cell response was much stronger: 80% of patients (12/15) had a robust response, a number that grew to 90% (14/15) after a booster. This response is “almost ideal” considering that the response in a nonimmunocompromised person would be about 99%, Dr. Wendtner said.

The study also revealed that vaccine responses were weaker in patients who took a combination of a Bruton tyrosine kinase inhibitor and venetoclax within a year.

Four patients developed COVID-19 infections with the Omicron variant about 6 months after vaccination. All had mild symptoms. A lone patient had a history of COVID-19 infection prior to vaccination.

The researchers noted that the study had several limitations, including its small size, its reliance on a single institution, and the differences in treatments and vaccination protocols among the patient population.

Broadly speaking, the study showed that “a vaccine is not in vain” in patients with CLL, “although the doctor might not detect an antibody response,” Dr. Wendtner said. He added that mixing vaccine types should provide more protection. Start with a viral vector vaccine followed by an mRNA vaccine or vice versa, he suggested.

In an interview, infectious disease physician Joshua A. Hill, MD, from Fred Hutchinson Cancer Center, Seattle, who wasn’t involved with the study, said it makes “important and interesting observations to reinforce other studies with similar findings.”

Specifically, Dr. Hill said, “despite the absence of a robust antibody response some of these patients who are on active treatment, patients can still generate robust cellular immune responses in the form of T-cell immunity. Our understanding is that having T cell immunity will provide important additional protection for developing severe disease, although is less easily tested.”

Opioids are widely regarded as a linchpin in the treatment of moderate to severe cancer-related pain and end-of-life symptoms; however, there are persistent racial and ethnic inequities in opioid access among older cancer patients, with Black patients being disproportionately affected, a new study suggests.

Black patients were more likely to undergo urine drug screening (UDS) despite being less likely to receive any opioids for pain management and receiving lower daily doses of opioids in comparison with White patients, the study found.

The inequities were particularly stark for Black men. “We found that Black men were far less likely to be prescribed reasonable doses than White men were,” said the study’s senior author, Alexi Wright, MD, MPH, a gynecologic oncologist and a researcher in the division of population sciences at Dana-Farber Cancer Institute, Boston. “And Black men were less likely to receive long-acting opioids, which are essential for many patients dying of cancer. Our findings are startling because everyone should agree that cancer patients should have equal access to pain relief at the end of life.”

The study was published on in the Journal of Clinical Oncology.

The researchers gathered data on 318,549 Medicare beneficiaries older than 65 years with poor-prognosis cancers who died between 2007 and 2019. During this time frame, for all groups, access to opioids declined and urine drug testing expanded, owing to the overall opioid epidemic in the United States. Overall, the proportion of patients near end of life (EOL) who received any opioid or long-acting opioids decreased from 42.2% to 32.7% and from 17.9% to 9.4%, respectively.

The investigators used National Drug Codes to identify all Medicare Part D claims for outpatient opioid prescriptions, excluding addiction treatments, cough suppressants, and parenteral opioids. They focused on prescriptions that were filled at least 30 days before death or hospice enrollment.

Among the study participants, the majority (85.5%) of patients were White, 29,555 patients (9.3%) were Black, and 16,636 patients (5.2%) were Hispanic.

Black and Hispanic patients were statistically less likely than White patients to receive opioid prescriptions near EOL (Black, –4.3 percentage points; Hispanic, –3.6 percentage points). They were also less likely to receive long-acting opioid prescriptions (Black, –3.1 percentage points; Hispanic, –2.2 percentage points).

“It’s not just that patients of color are less likely to get opioids, but when they do get them, they get lower doses, and they also are less likely to get long-acting opioids, which a lot of people view as sort of more potential for addiction, which isn’t necessarily true but kind of viewed with heightened concern or suspicion,” the study’s lead author, Andrea Enzinger, MD, a gastrointestinal oncologist and a researcher in Dana-Farber’s division of population sciences, said in an interview.

Dr. Enzinger added that she believes systemic racism and preconceived biases toward minorities and drug addiction may be contributing to these trends.

When Black patients did receive at least one opioid prescription, they received daily doses that were 10.5 morphine milligram equivalents (MMEs) lower than doses given to White patients. Compared with the total opioid dose filled per White decedent near EOL, the total dose filled per Black decedent was 210 MMEs lower.

“We all need to be worried about the potential for misuse or addiction, but this is the one setting that is very low on my priority list when somebody is dying. I mean, we’re looking at the last month of life, so nobody has the potential to become addicted,” Dr. Enzinger commented.

The team also evaluated rates or urine drug screening (UDS), but as these rates were relatively low, they expanded the time frame to 180 days before death or hospice. They found that disparities in UDS disproportionately affected Black men.

From 2007 to 2019, the proportion of patients who underwent UDS increased from 0.6% to 6.7% in the 180 days before death or hospice; however, Black decedents were tested more often than White or Hispanic decedents.

Black decedents were 0.5 percentage points more likely than White decedents to undergo UDS near EOL.

“The disparities in urine drug screening are modest but important, because they hint at underlying systematic racism in recommending patients for screening,” Dr. Wright said. “Screening needs to either be applied uniformly or not at all for patients in this situation.”

The researchers acknowledged that their findings likely do not represent the full spectrum of prescribing disparities and believe that the work should be expanded among younger populations. Nevertheless, the investigators believe the work highlights the persistent racial and ethnic disparities in opioid access.

The study was supported by a grant from the Agency for Healthcare Research and Policy.
