Postpartum hemorrhage is the leading cause of maternal mortality worldwide, accounting for 25% of deaths from obstetric causes. Although balloon tamponade has been widely used to manage uncontrolled postpartum bleeding, a recent evaluation of an intrauterine vacuum-induced hemorrhage control device demonstrated impressive safety and effectiveness, researchers reported at the meeting sponsored by the Society for Maternal-Fetal Medicine.

“It’s exciting to see new technology and new potential treatment modalities. We just don’t have that many tools in our toolkit right now,” said Dena Goffman, MD, professor of women’s health and obstetrics and gynecology and vice chair of quality and patient safety at Columbia University’s Irving Medical Center, in New York, who presented the findings.

Dr. Goffman led an earlier multicenter prospective single-arm treatment study of the Jada System, a vacuum device marketed by Organon. The U.S. Food and Drug Administration approved use of the Jada System in October 2020.

Dr. Goffman said she and her colleagues felt “a next logical step would be to see what happens with real-world use.” In the new study, researchers at 16 U.S. medical centers reviewed medical charts of 800 women who underwent treatment with the Jada System between October 2020 and April 2022.

Treatment was successful in 92.5% of the vaginal births (n = 530) and 83.7% of the cesarean births (n = 270), similar to the results of the initial treatment trial that led to FDA approval, according to the researchers. For both types of delivery, bleeding was controlled in less than 5 minutes for most patients. Three serious adverse events were identified that could have been related to use of the device (two in vaginal births, one in cesarean birth), they reported.

Although the study was not designed to directly compare the Jada System with balloon tamponade, in a recent meta-analysis, it was estimated that tamponade controls postpartum hemorrhage in roughly 87% of cases, with complication rates in as many as 6.5% among women who undergo the procedure.

Dr. Goffman pointed out additional benefits. The vacuum device typically must stay in place for less time (3.1 hours for vaginal birth and 4.6 hours for cesarean birth) than balloon tamponade, allowing women to recover more quickly. In the initial trial, which Dr. Goffman helped conduct, 98% of clinicians reported that the device was easy to use, which increases its attractiveness in lower-income countries. Dr. Goffman felt that the device “has potential for huge impact” in those countries, given the high rates of maternal morbidity and mortality in these areas.

Amber Samuel, MD, medical director of OBSETRIX Maternal Fetal Medicine Specialists of Houston, said the device recently became available in the hospitals in which she works, and she has used the Jada System several times. Like Dr. Goffman, she was excited to have a new tool for treating a life-threatening condition.

Although the device has been on the market for more than 2 years, Dr. Samuel felt clinicians who were reluctant to adopt a new technology would be reassured by the findings.

“We should make sure that it’s effective, and we should know what the safety profile is,” said Dr. Samuel, adding that “the more data we have, the more we’re able to counsel patients and work this into our protocols for what is a really common obstetric problem.”

Both Dr. Goffman and Dr. Samuel agreed that more data, ideally from randomized clinical trials, are needed to convince professional groups such as the American College of Obstetricians and Gynecologists to state a clear preference for use of vacuum-induced hemorrhage control devices over balloon tamponade.

“We should be supporting further investigation,” Dr. Goffman said, “but for people who have this tool available to them now, I think they can feel confident in using it.”

The study was funded by Alydia Health, the manufacturer of the Jada System. Alydia Health was acquired by Organon in 2021. Study sites received research-related financial support, but none of the authors received direct payments from Alydia Health/Organon. Dr. Goffman serves on the scientific advisory board of Alydia Health/Organon. Dr. Samuel has disclosed no relevant financial relationships.

A new randomized, open-label French trial offers more evidence that the discontinuation of oxytocin treatment after the earliest stages of labor may be safe. Stopping oxytocin didn’t appear to affect neonatal outcomes, compared with continual use of the medication. However, the first stage of labor lasted slightly longer – not surprisingly – in those in the intervention group, and many of those who stopped oxytocin treatment resumed it later.

“Our trial did not show any impact of oxytocin discontinuation in the active [labor] stage on neonatal morbidity cesarean delivery, postpartum hemorrhage, birth experience, and postpartum depression,” said Aude Girault, MD, PhD, of Paris Cité University, in a presentation in San Francisco at the meeting sponsored by the Society for Maternal-Fetal Medicine.

The goal of the STOPOXY study is to build upon previous research that found oxytocin discontinuation didn’t boost the risk of cesarean delivery rates, uterine hyperstimulation, and abnormal fetal heart rate, Dr. Girault said. “These studies were underpowered to show any effects on neonatal morbidity,” so she and colleagues decided to dig deeper into the issue by launching the new trial.

From 2020 to 2022, researchers assigned 2,367 women who received oxytocin before 4 centimeters dilation to either continue with the drug (n = 1,192) or discontinue it before reaching 6 centimeters dilation (n = 1,175). Overall, the women were pregnant for the first time (around 55%) with a median age around 32 years and body mass index around 24.1 kg/m². All had live, singleton, full-term babies.

More than a third – 37% – of those who discontinued oxytocin resumed treatment with the medication, while 5% of those in the control group stopped taking it.

The neonatal morbidity rate – defined via a composite variable based on umbilical arterial pH, umbilical arterial lactates, Apgar score, and/or neonatal ICU admission – was 10.0% in the intervention group and 10.1% in the control group (P = .94), the researchers reported. Cesarean delivery rates were similar (18.8% vs. 16.5%, respectively; P = .22). Apart from the duration of the active first stage, which was significantly higher in the intervention group (100 min [ interquartile range, 50-208 min] vs. 90 min [IQR, 45-150 min]; P = .001), there were no significant differences between the groups.

Dr. Girault said this increase in labor duration was “moderate and clinically debatable.”

In an interview, oncologist-gynecologist George Saade, MD, of the University of Texas Medical Branch, Galveston, noted that “oxytocin is frequently used for either induction or augmentation of labor ... with the goal of improving maternal and neonatal outcomes.”

Oxytocin itself is not expensive, Dr. Saade said. “However, when it is given, the patient requires more monitoring, which may increase cost.”

There’s debate over the proper use of oxytocin, which is available in a synthetic version as Pitocin, and researchers have been trying to understand whether it can safely be discontinued early in labor.

Potential side effects of oxytocin include heart disorders such as arrhythmia, asphyxia, neonatal seizure, and jaundice, low Apgar score, and fetal death. A boxed warning says: “Because the available data are inadequate to evaluate the benefits-to-risks considerations, oxytocin is not indicated for elective induction of labor.”

However, “overall oxytocin is commonly used and very safe as long as careful protocols are followed,” David N. Hackney, MD, MS, of University Hospitals Cleveland, said in an interview. “The medication itself does not have many negative side effects. With very high doses there can be a concern for water intoxication, though this is clinically very uncommon. Some prior studies have raised concerns about the use of oxytocin and subsequent long-term neurodevelopmental outcomes, though these associations are likely confounders and the mainstream opinion is that these are not truly biologically causative associations.”

A 2021 study in The BMJ randomly assigned 1,200 women to continue or discontinue oxytocin. There was a slight increase in cesarean sections in the discontinuation group but significantly lower risks of uterine hyperstimulation and abnormal fetal heart rate.

Dr. Hackney, who didn’t take part in the new study, said the trial is “well conducted and well executed.” However, it needs peer review before any of its findings should change practice.

He added that differences in delivery protocols between the United States and France should be considered. As he noted, Dr. Girault mentioned in a Q&A after her presentation that delayed second-stage labor is more common in France than in the United States.

The study was funded by the French National Ministry of Health. Disclosures for the authors were not provided. Dr. Saade and Dr. Hackney have no disclosures.

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.

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.

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.”

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.

Oncocyte funded this study. Dr. Varga and several other study authors are Oncocyte employees, and another author is a paid consultant to the company.

A survey of physicians treating breast cancer patients finds that many use diagnostic mammograms for surveillance rather than screening mammograms, despite lack of evidence for a clinical difference.

Existing guidelines offer little help, according to Pavani Chalasani, MD, MPH, who presented the study at the San Antonio Breast Cancer Symposium. “They just say [do an] annual mammogram, but they don’t say, ‘Do we need to do screening? Do we need to do breast MRIs?’”

Her personal experience also reflected a general confusion. “I asked my colleagues and got different answers from seven colleagues,” said Dr. Chalasani, who is an oncologist at the University of Arizona Cancer Center, Tucson.

She noted that diagnostic mammograms are generally similar to screening mammograms, but the radiologist is viewing the images in real time and can take additional views as needed while the patient is still present. “That is the biggest difference,” said Dr. Chalasani. No studies have been conducted to determine which method produces better results.

To get a snapshot of current practice, she and her colleagues developed a survey, which the American Society of Clinical Oncology sent to 1,000 randomly selected members between Oct. 19 and Nov. 22, 2021. 244 individuals responded; 93.5% were physicians, and half identified as female. A total of 174 respondents were medical oncologists, 31 were radiation oncologists, and 20 were surgical oncologists. The imbalance among respondents is a limitation of the study. That “may or may not be reflective of our real-time practices (among surgeons), but we do think that since a lot of times patients are seen by medical oncologists, there could be overlap,” said Dr. Chalasani.

About 50% of respondents said that they use breast MRI in the diagnosis of 25% or fewer patients. Approximately 64% of respondents said they used diagnostic mammograms versus about 31% who used imaging mammograms at first imaging. About 53% said they ordered mammograms within the first 6 months after treatment.

38% of those who ordered diagnostic mammograms for surveillance used it for 3-5 years, while 29% continued it for 5 years or more. One-quarter employed additional imaging during follow-up, most commonly breast ultrasound. About 65% said they had no stop date for screening mammograms, as long as the patient remained healthy. The choice of screening or diagnostic mammography was about 50:50, though about 55% said they use screening mammography for patients 80 years of age or older.

Dr. Chalasani pointed out that both screening and diagnostic mammograms provide similar imaging quality. Screening mammograms are completely covered by insurance, while diagnostic mammograms typically require a copay. “We’re doing this [diagnostic mammography] with no guidelines, but there is this out of pocket cost, without knowing if it’s the right thing to do,” she said.

National Comprehensive Cancer Network guidelines indicate that diagnostic mammograms can be conducted for 5 years after a ductal carcinoma in situ diagnosis, but it doesn’t provide guidance for invasive cancers. Some past studies suggested that doing diagnostic mammograms for 3 years may increase diagnosis, but it isn’t clear if any such advantage would actually result in a clinical difference, according to Dr. Chalasani. “With the treatments we have, we still might cure [the cancer]. So what endpoints are we looking for? Are we changing care to add on toxicity to the patient, and stress to the patient and also for the health care system?”

She hopes that physicians will look at the results and understand that diagnostic mammograms, while they intuitively feel superior, are not supported by guidelines, and patients must incur an extra cost.

Her team also plans to conduct cost-effectiveness analysis of diagnostic mammograms.

Dr. Chalasani has no relevant financial disclosures.

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.

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.

AURORA, COLO. – Inflammatory bowel disease doesn’t respect international borders, and clinicians who help in diet planning for patients with IBD should take into account cultural differences regarding food and eating, a nutrition specialist recommends.

“Many patients are in an environment that they’re not used to, an environment where most people speak English and their customs and their language may differ from the individual providing care to them. They’re often told, in addition, to eat foods that they may not even have heard of. It can really be a scary situation for many of these patients,” said Neha D. Shah, MPH, RD, CNSC, a dietitian at University of California San Francisco Health.

“Put yourself in their shoes. [Consider] what would make you feel more comfortable in that environment, and then apply that perspective to the care of your patient,” she advised colleagues at the annual Crohn’s & Colitis Congress^®, a partnership of the Crohn’s & Colitis Foundation and the American Gastroenterological Association.

Ms. Shah explained that by incorporating understanding of cultural differences and food culture into the care of persons with IBD, clinicians can help patients from different ethnic backgrounds accept diets that both contain familiar foods and also help to ameliorate their gastrointestinal symptoms.
 

Food culture and acculturation

As of 2016, the estimated prevalence of IBD among pediatric patients in the United States was 77 per 100,000, and the prevalence in adults was estimated at 478.4 per 100,000. In a 2021 study of the effects of race and ethnicity on the diagnosis and management of IBD, the authors estimated that the prevalence of IBD in the United States was about 3.1 million persons, or 1.3% of the population, with an increase in prevalence in non-White persons and ethnicities, she noted.

Some of the increasing prevalence among minority populations may be attributable to diet acculturation, when members of a particular group partially or completely adopt the eating patterns and/or food choices of the host country.
 

Culturally appropriate foods

The term “food culture” refers to “the sociocultural aspect of eating, and include[s] the beliefs, values, and attitudes a community may accept around food,” she said.

Ms. Shah provided examples of culturally appropriate foods that may be tolerated by patients with IBD, such as beans, tortillas, chicken with rice, guacamole, mangos, and tomatoes in persons from South America, or lentils, breads, rice, oats, spinach, and tea among patients from the Indian subcontinent.

By understanding and respecting cultural differences, learning how to best communicate with persons of other cultures, and by being aware of one’s own biases, clinicians can better help patients create diet plans that fit within their expectations and lifestyles, she said.

For example, patients can be encouraged to incorporate more culturally familiar plant-based foods such as legumes to manage active disease and maintain remissions.

Patients with active disease should have at least one-half cup of one form of culturally appropriate fiber at each meal. The dietitian should consider recommending blending fiber into other foods or serving it cooked, mashed, or minced, depending upon the patient’s level of tolerance.

During the transition phase, patients can reintroduce an additional half cup of fiber at one meal, then at two meals, and finally at three daily meals. Patients can see whether they can tolerate more raw or whole high-fiber foods at this stage.

During remissions, patients should be advised to add two to three foods containing culturally appropriate fiber at each meal, she said.
 

‘Eye-opening’ realization

“I think it’s really eye-opening for us to think about how we have to have culturally sensitive discussions with our patients,” commented Sandra Kim, MD, from the University of Pittsburgh Medical Center, who moderated the session.

Dr. Kim asked Ms. Shah what advice she’d give to pediatric gastroenterologists about engaging patients and their families.

The clinician should ask both patients and parents about what the child eats and what the challenges of eating under certain circumstances are, and have culturally appropriate resources on hand.

Ms. Shah did not report a funding source for her work. She disclosed compensation as editor of the Journal of Practical Gastroeneterology and as GI on Demand–consultant for a joint virtual platform from the American College of Gastroenterology and Gastro Girl. She also serves as treasurer and director of operations for the South Asian IBD Alliance.

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 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.

Antibiotic use doesn’t appear to disrupt the effectiveness of the immune checkpoint inhibitor durvalumab in advanced biliary tract cancer, according to a new analysis of the landmark TOPAZ-1 clinical trial.

The findings, released at the ASCO Gastrointestinal Cancers Symposium 2023, suggest that “people with advanced biliary tract cancer can safely be treated with antibiotics while still benefiting from treatment with durvalumab plus chemotherapy,” said lead author Aiwu Ruth He, MD, PhD, a gastrointestinal oncologist with MedStar Georgetown University Hospital, Washington.

Antibiotic use during immune checkpoint inhibitor therapy has been associated with poorer outcomes. A review of 12 studies published in Frontiers in Oncology found that antibiotic use was associated with worse progression-free and overall survival.

“Patients with biliary tract cancer have the increased risk of biliary tract infection as the result of biliary tract obstruction, and they often receive antibiotics,” Dr. He said.

A 2020 report in eCancer suggested that antibiotics may disrupt gut bacteria and, as a result, interfere with the immune system’s responsiveness. “It has been a consensus that the use of broad-spectrum antibiotics should be avoided during the use of immunotherapy whenever possible,” the report authors wrote. “In addition, antibiotics should be prescribed only when properly indicated.”

However, cutting down on antibiotic use may be especially difficult in cancer patients since they frequently suffer from infections. “An antibiotic-resistant bacterial infection may cause serious issues for a cancer patient, who likely already has a suppressed immune system,” according to a 2017 information sheet posted by the Cancer Treatment Centers of America. “Chemotherapy may cause neutropenia, a reduction of white blood cells that help fight infections and viruses. Radiation therapy may damage the skin and cause irritation and wounds. Immunotherapy or targeted therapy drugs may trigger side effects that may lead to infections. Incisions from surgery or to insert ports or catheters may be vulnerable to infections.”

The new study

For the new subgroup analysis, researchers analyzed data from the phase 3 TOPAZ-1 clinical trial, which was a double-blinded analysis of durvalumab plus gemcitabine and cisplatin in advanced biliary tract cancer. The previously reported main findings from the study were positive with a median overall survival of 12.8 months in the durvalumab arm versus 11.5 months in the placebo arm (hazard ratio, 0.80; P = .021). These findings contributed to the Food and Drug Administration’s decision in 2022 to approve the treatment for use in locally advanced or metastatic biliary tract cancer.

Of 341 patients who received durvalumab treatment, 167 also took antibiotics. The median overall survival in the antibiotic and nonantibiotic groups were similar at 12.6 months (95% confidence interval, 9.7-14.8 months) and 13 months (95% CI, 10.8-14.7 months), respectively. Median progression-free survival was 7.3 months (95% CI, 6.5-7.7 months) and 7.2 months (95% CI, 5.9-7.4 months), respectively.

“The results support that advanced patients’ risk of death, and the risk that their cancer would grow, spread, or get worse, was not meaningfully different between patients who used antibiotics and those who did not use antibiotics at the same time as they were receiving durvalumab-based treatment,” Dr. He said. “The result is not surprising to me since it is not clear to me how and why antibiotics may affect the effectiveness of immunotherapy.”

Moving forward, she said, “additional studies are needed to further investigator the relationship between antibiotics use and effectiveness of immunotherapy. We need to understand why use of antibiotics during treatment with immunotherapy is correlated with poor outcomes in some circumstances but not in other circumstances.”

Montrouge, France – Four in five women will be infected by one or more human papillomavirus (HPV) strains during their lifetimes. For most of these women, the HPV will be cleared from the body, but 5% of them will develop precancerous lesions in the cervix. The role of vaginal flora in persistent HPV has been brought into focus by research studies carried out over the past few years.

At a press conference ahead of the 46th meeting of the French Colposcopy and Cervical and Vaginal Diseases Society, Julia Maruani, MD, a medical gynecologist in Marseille, France, took the opportunity to discuss the importance of vaginal flora and the need to treat cases of bacterial vaginosis.
 

Striking a balance

Essential for reducing the risk of sexually transmitted infections, a healthy vaginal flora is made up of millions of microorganisms, mainly lactobacilli, as well as other bacteria (Gardnerella vaginalis, Atopobium vaginae, Prevotella, streptococcus, gonococcus), HPV, and fungi.

Lactobacilli produce lactic acid, which reduces the vagina’s pH, as well as hydrogen peroxide, which is toxic to the other bacteria.

Different factors, such as alcohol, a diet rich in polyunsaturated fatty acids and sugar, and especially smoking, can lead to an imbalance of the bacteria in the vaginal flora and thus result in vaginosis. What occurs is an abnormal multiplication of different types of anaerobic bacteria that are normally present in much lower numbers. There is a relative reduction in lactobacilli, which results in an increased vaginal pH, a greater risk of contracting an STI, and reduced clearance of the HPV infection. “Women who smoke probably experience persistent HPV infections due to an imbalance in vaginal flora,” said Dr. Maruani.
 

Vaginosis and HPV

When there are fewer lactobacilli than there should be, these bacteria can no longer protect the vaginal mucosa, which is disrupted by other bacteria. “HPV then has access to the basal cells,” said Dr. Maruani, acknowledging that the relationship between bacterial vaginosis and persistent HPV infections has been the subject of numerous research studies over the past decade or so. “For years, I would see this same link in my patients. Those with persistent vaginosis were also the ones with persistent HPV. And I’m not the only one to notice this. Studies have also been carried out investigating this exact correlation,” she added.

These studies have shown that HPV infections persist in cases of vaginosis, resulting in the appearance of epithelial lesions. Additionally, the lesions are more severe when dysbiosis is more severe.

What about probiotics? Can they treat dysbiosis and an HPV infection at the same time? “Probiotics work very well for vaginosis, provided they are used for a long time. We know that they lessen HPV infections and low-grade lesions,” said Dr. Maruani, although no randomized studies support this conclusion. “It’s not a one size fits all. We aren’t about to treat patients with precancerous lesions with probiotics.” There are currently no data concerning the efficacy of probiotics on high-grade lesions. These days, Dr. Maruani has been thinking about a new issue: the benefit of diagnosing cases of asymptomatic vaginosis – because treating them would reduce the risk of persistent HPV infection.
