Key clinical point: Presence of dactylitis independently confirmed more severe disease burden with higher swollen joint counts (SJC), C-reactive protein (CRP) levels, ultrasound-detected synovitis, and bone erosion in disease-modifying antirheumatic drug (DMARD)-naive patients with early psoriatic arthritis (PsA).

Major finding: Dactylitic vs. nondactylitic PsA was associated with a higher SJC (P < .001) and CRP level (P = .006) and a higher prevalence of ultrasound synovitis (P < .001) and bone erosions (P < .001). After excluding dactylitic digits, SJC was greater (P = .002) and ultrasound-detected synovitis (P < .001) and erosions (P = .008) were more prevalent in dactylitic vs. nondactylitic PsA.

Study details: This study included 177 DMARD-naive patients with early PsA who were stratified by the presence or absence of dactylitis at baseline.

Men and White people receive better treatment for gastroesophageal cancer than women, Blacks, and Latinos despite years of studies highlighting disparities in care, researchers say.

The problem is complex because it stems from both biological and socioeconomic factors, but some signs of improvement are beginning to show, said Nathaniel R. Evans III, MD, a professor of surgery at Thomas Jefferson University in Philadelphia.

“Repeatedly, we see that, although we know how patients should be treated, there are oftentimes subsets of patients who don’t receive that same level of care,” said Dr. Evans in a general session talk at the American Society of Clinical Oncology Gastrointestinal Cancers Symposium.

Black patients with esophageal cancer are 38% more likely to die from the condition than White patients, he said, citing a 2013 study (Ann Surg Oncol. 2013 doi: 10.1245/s10434-012-2807-3). For Latino patients, mortality is 20% higher than for White patients.

The difference can mostly be explained by the rate of esophagectomy, which is 52% lower for Black patients and 29% lower for Latino patients, compared with White patients, the study found.

Besides race and gender, insurance status also influences who gets surgery, Dr. Evans said, citing data from the National Cancer Database. Black patients are less likely to get surgery and more likely to die at all stages and histologies, he said. They wait longer for treatment and are more likely to receive no treatment at all.

Women also suffer from disparities, said Anna Dorothea Wagner, MD, head of the gastrointestinal cancer clinic at Lausanne University Hospital in Lausanne (Switzerland), who spoke at the symposium with Dr Evans.

Seventy-five percent of men with esophageal and gastric adenocarcinoma get curative treatments, compared with only 60% of women, Dr. Wagner said, citing a 2020 study on which she is an author. Women are more likely to get palliative care. As a result, only 30% of women survive the condition for 5 years or more compared to 34% of men, she said. “At the moment we don’t know whether this is due to either patient preferences or cognitive or bias of physicians.”

Disparities in treatment outcomes because of biological differences

For women, some disparities also arise out of clear biological differences, Dr. Wagner said. Sex hormone signaling affects cancer susceptibility, and sex-biased gene expression signatures have been detected in multiple cancer types.

Women with poorly differentiated and signet-cell pathology are less likely to survive their cancer than men with the same histology, she said.

Many studies have shown that chemotherapy is more toxic to women than men without being more efficacious, she added. This suggests that the optimal doses might be different for women and men.

Responding to a question from the audience, Dr. Wagner said more research is needed on transgender patients to understand how these factors affect them.

Dr. Evans attributed the racial and ethnic disparities to some combination of differential histology, stage at diagnosis, access to care, socioeconomics, and inherent bias.

“The problem is not new,” Dr. Evans said. He described studies that found disparities in the 1970s. “But the good news is that things do seem to be getting better.”

Between 2000 and 2011, the number of esophagectomies being performed at high-volume hospitals increased, he said. The overall mortality after esophagectomy has consequently decreased over this time, and the gap in this rate between White and Black people has closed, he said. “Specialization and centralization clearly improve outcomes for certain surgical procedures.”

To address the problem everyone should acknowledge the disparities, particularly in the access to surgery. “I think one of the best tools we have to try to address the disparity is education, both for patients and providers,” Dr. Evans said.

Care teams must become more diverse and culturally competent to combat longstanding distrust and improve communication, he said.

In December, ASCO announced an “action plan” to address equity, diversity and inclusion in cancer care. The organization promised to improve clinical trial eligibility, and train researchers about inherent bias in order to make the trials more representative of the cancer population.

It vowed to increase participation of underrepresented groups in its professional development programs and leadership roles, and educate its members about equity. And, it resolved to provide resources to providers so they could advocate for better quality of care, especially in rural and disadvantaged settings.

Dr. Wagner disclosed relationships with Alligator Bioscience, BMS, Dragonfly Therapeutics, Lilly, Merck KGaA, MSD Oncology, Servier/Pfizer, and Abbvie. Dr. Evans disclosed relationships with Bristol Myers Squibb Foundation and Intuitive Surgical.

Women also suffer from disparities, said Anna Dorothea Wagner, MD, head of the gastrointestinal cancer clinic at Lausanne University Hospital in Lausanne (Switzerland), who spoke at the symposium with Dr Evans.

Seventy-five percent of men with esophageal and gastric adenocarcinoma get curative treatments, compared with only 60% of women, Dr. Wagner said, citing a 2020 study on which she is an author. Women are more likely to get palliative care. As a result, only 30% of women survive the condition for 5 years or more compared to 34% of men, she said. “At the moment we don’t know whether this is due to either patient preferences or cognitive or bias of physicians.”

Disparities in treatment outcomes because of biological differences

For women, some disparities also arise out of clear biological differences, Dr. Wagner said. Sex hormone signaling affects cancer susceptibility, and sex-biased gene expression signatures have been detected in multiple cancer types.

Women with poorly differentiated and signet-cell pathology are less likely to survive their cancer than men with the same histology, she said.

Many studies have shown that chemotherapy is more toxic to women than men without being more efficacious, she added. This suggests that the optimal doses might be different for women and men.

Responding to a question from the audience, Dr. Wagner said more research is needed on transgender patients to understand how these factors affect them.

Dr. Evans attributed the racial and ethnic disparities to some combination of differential histology, stage at diagnosis, access to care, socioeconomics, and inherent bias.

“The problem is not new,” Dr. Evans said. He described studies that found disparities in the 1970s. “But the good news is that things do seem to be getting better.”

Between 2000 and 2011, the number of esophagectomies being performed at high-volume hospitals increased, he said. The overall mortality after esophagectomy has consequently decreased over this time, and the gap in this rate between White and Black people has closed, he said. “Specialization and centralization clearly improve outcomes for certain surgical procedures.”

To address the problem everyone should acknowledge the disparities, particularly in the access to surgery. “I think one of the best tools we have to try to address the disparity is education, both for patients and providers,” Dr. Evans said.

Care teams must become more diverse and culturally competent to combat longstanding distrust and improve communication, he said.

In December, ASCO announced an “action plan” to address equity, diversity and inclusion in cancer care. The organization promised to improve clinical trial eligibility, and train researchers about inherent bias in order to make the trials more representative of the cancer population.

It vowed to increase participation of underrepresented groups in its professional development programs and leadership roles, and educate its members about equity. And, it resolved to provide resources to providers so they could advocate for better quality of care, especially in rural and disadvantaged settings.

Dr. Wagner disclosed relationships with Alligator Bioscience, BMS, Dragonfly Therapeutics, Lilly, Merck KGaA, MSD Oncology, Servier/Pfizer, and Abbvie. Dr. Evans disclosed relationships with Bristol Myers Squibb Foundation and Intuitive Surgical.

Men and White people receive better treatment for gastroesophageal cancer than women, Blacks, and Latinos despite years of studies highlighting disparities in care, researchers say.

The problem is complex because it stems from both biological and socioeconomic factors, but some signs of improvement are beginning to show, said Nathaniel R. Evans III, MD, a professor of surgery at Thomas Jefferson University in Philadelphia.

“Repeatedly, we see that, although we know how patients should be treated, there are oftentimes subsets of patients who don’t receive that same level of care,” said Dr. Evans in a general session talk at the American Society of Clinical Oncology Gastrointestinal Cancers Symposium.

Black patients with esophageal cancer are 38% more likely to die from the condition than White patients, he said, citing a 2013 study (Ann Surg Oncol. 2013 doi: 10.1245/s10434-012-2807-3). For Latino patients, mortality is 20% higher than for White patients.

The difference can mostly be explained by the rate of esophagectomy, which is 52% lower for Black patients and 29% lower for Latino patients, compared with White patients, the study found.

Besides race and gender, insurance status also influences who gets surgery, Dr. Evans said, citing data from the National Cancer Database. Black patients are less likely to get surgery and more likely to die at all stages and histologies, he said. They wait longer for treatment and are more likely to receive no treatment at all.

A new French study raises the possibility that immunotherapy can help some people with stomach cancer avoid surgery.

GERCOR NEONIPIGA was a phase 2 study with no comparator group and only 32 patients, but even so, after a 6-cycle course of nivolumab and ipilimumab, there was no sign of tumor in 17 of the 29 patients (59%) who had surgery specimens evaluable by pathology.

Indeed, two patients refused surgery after their preop endoscopic biopsies came back clear with no tumor cells. Surgery was called off in a third patient who developed metastases beforehand.

After a median of 12 months follow-up, there’s was no recurrence or progression in 30 patients (94%). The remaining two included the metastatic patient and one who died 3 days after surgery from cardiovascular complications.

If the findings pan out with additional research, the approach could be a boon for people who respond. “Avoiding surgery is a dream for these patients,” said lead investigator Thierry Andre, MD, a medical oncology professor at Sorbonne University, Paris, when he presented the findings at the American Society of Clinical Oncology Gastrointestinal Cancers Symposium.

The trial “raises the question whether surgery can be delayed or avoided in some patients with localized” disease. Given the findings, “it seems possible not for all but probably for half, maybe more.” As in the two subjects who opted out of surgery, preop endoscopic biopsies could be used to identify complete responders with active surveillance afterwards, he said.

The study included 16 patients with gastric cancer and 16 with esophagogastric adenocarcinoma. They were mismatch repair deficient, which Dr. Andre said predicts response to immunotherapy.

At baseline, 22 had stage T3 disease and four had stage T2 disease, and stage was not evaluable by echo-endoscopy in 6. Nodal status was unknown, but the patients had no metastases at baseline.

They underwent six nivolumab 240-mg infusions and two ipilimumab 1–mg/kg infusions over 12 weeks, followed by R0 resections a median of 5 weeks after the last nivolumab injection.

Surgical specimens from 17 patients (59%) showed a complete pathological response to neoadjuvant immunotherapy (Becker tumor regression grade (TRG) 1a, ypT0N0). TRG was 1b – less than 10% residual tumor in tumor bed in four patients. TRG was 2 in two patients with 10%-50% of residual tumor remaining, and six had a TRG of 3 with more than half of the tumor remaining after immunotherapy.

Based on tumor response, 25 patients had nine additional nivolumab infusions after surgery with 480 mg infused monthly.

Dr. Andre explained that people want to avoid surgery because of the substantial morbidity that was shown in the study, plus 54% of patients had complications, including anastomotic leaks, pancreatitis, pneumonia, and other problems.

There were no new safety signals with neoadjuvant therapy; 25% of patients had grade 3 or 4 events.

The study was conducted in 10 centers in France. About three-quarters of the subjects were men and the median age was 65 years.

Bristol Meyers Squibb supplied the nivolumab and ipilimumab and partially funded the work. Many of the investigators had ties to the company, including Dr. Andre, who is a consultant for BMS and reported payments from the company.

Allopurinol treatment is not associated with increased mortality in patients with gout and chronic kidney disease even at 5 years after starting treatment, a study has found.

Around one in five patients with gout also have chronic kidney disease, and previous research suggests that hyperuricemia is itself a contributor to renal disease, which is why there has been interest in the use of serum urate–lowering medication in patients with both conditions.

Since the publication of two earlier randomized controlled trials suggested a twofold increase in mortality among patients with renal disease who were treated with allopurinol in an attempt to slow progression, there has been wariness about the drug in patients with compromised renal function.

In a study published in Annals of Internal Medicine, Jie Wei, PhD, of Xiangya Hospital at Central South University in Changsha, China, and coauthors report the results of their retrospective, population-based study of 5,277 adults aged 40 and older with gout and moderate to severe chronic kidney disease who were initiated on allopurinol and 5,277 matched individuals not on allopurinol.

At 5 years after the patients started allopurinol, the study found that mortality was a statistically significant 15% lower (hazard ratio, 0.85; 95% confidence interval, 0.77-0.93) among those on allopurinol, compared with those not taking the drug. The rate was 4.9 deaths per 100 person-years among those on allopurinol, compared with 5.8 among those not taking it.

The researchers also created two simulated randomized clinical trials from the data for initiators of allopurinol, replicating each initiator twice. The first trial assigned patient replicates either to achieving a target serum urate level of less than 0.36 mmol/L within a year or not achieving it. The second assigned patient replicates to either an allopurinol dose-escalation group or no dose escalation.

For the target serum urate level study, 1,484 achieved the target, and this was associated with a 13% lower hazard ratio for mortality that just missed statistical significance (HR, 0.87; 95% confidence interval, 0.75-1.01).

In the dose-escalation study, there were 773 participants who increased their dose of allopurinol in the first year after initiation – from a median of 100 mg/day to a median final dose of 300 mg/day – and 2,923 who didn’t. Those who escalated their dose had a nonsignificant 12% lower risk of mortality (HR, 0.88; 95% CI, 0.73-1.07), compared with those who didn’t.

The authors suggest that this could be the result of confounding, as patients who achieved target serum urate levels may have been of better health generally than those who didn’t, which could also have contributed to lower mortality.

Coauthor of the study Yuqing Zhang, DSc, of Massachusetts General Hospital and Harvard Medical School, Boston, said there had previously been a theory that allopurinol could protect against progression of renal disease. However, the two randomized, controlled trials in patients with chronic kidney disease but not gout published in 2020 suggested that allopurinol was instead associated with a doubling of mortality in this group.

“This study really shows convincing evidence that among gout patients with renal disease, allopurinol does not increase mortality,” Dr. Zhang told this news organization. He suggested the reason that the earlier studies had found higher mortality among patients on allopurinol was because those patients did not have gout. Given that gout can increase mortality, treating it effectively with allopurinol may therefore reduce mortality even in patients with concurrent chronic kidney disease.

Commenting on the study, Angelo Gaffo, MD, from the Birmingham VA Medical Center and the division of rheumatology at the University of Alabama at Birmingham, said that, while there had been data suggesting increased mortality, the findings from this “very well-done” study were reassuring and even suggested a possible decrease in mortality associated with allopurinol.

“I wouldn’t scream it out loud because it needs confirmation, but it’s something also that we have a sense that could be true,” he said.

Dr. Gaffo noted that patients treated with allopurinol tended to be those with fewer comorbidities. “Patients who have a lot of comorbidities probably are less likely to have their dose of allopurinol started or increased because of some concerns that practitioners may have about putting them on another medicine or increasing the dose of that medicine,” he said.

He also stressed that the findings still need replication in other large database studies, given that a prospective, randomized clinical trial addressing such a question would be difficult to conduct.

The study was supported by the Project Program of National Clinical Research Center for Geriatric Disorders, the National Natural Science Foundation of China, and the U.S. National Institutes of Health. Two authors reported consulting fees from the pharmaceutical sector unrelated to the study. No other conflicts of interest were declared.
