Seventeen years ago, Philip Segal, a retired accountant from suburban Toronto, Canada, was diagnosed with prostate cancer in a private clinic. After rejecting brachytherapy recommended by an oncologist, he went on active surveillance to watch, but not treat, the Gleason 6 (grade group 1) tumor. As he approaches his 80th birthday later this year, Mr. Segal said he plans to maintain the status quo. “It definitely brings me some peace of mind. I’d rather do that than not follow it and kick myself if there was a serious change,” he said.

Meanwhile, 2 years ago and 200 miles away in suburban Detroit, Bruno Barrey, a robotics engineer, was diagnosed with three cores of Gleason 6 and went on active surveillance.

Six months after the original diagnosis, however, Mr. Barrey, 57, underwent a follow-up biopsy. This time, all 16 cores were positive, with a mix of low-risk Gleason 6 and more advanced Gleason 3 + 4 lesions. His tumor was so large he underwent radiation therapy in 2023, ending his brief stint on the monitoring approach.

The two cases illustrate the complicated truth of active surveillance. For some men, the strategy can prove to be short-lived, perhaps 5 years or less, or a life-long approach lasting until the man dies from another cause.

Which kind of race a man will run depends on a wide range of factors: His comfort level living with a cancer, or at least a tumor that might well evolve into an aggressive malignancy, changes in his prostate-specific antigen (PSA) level and results of a magnetic resonance imaging test, the volume of his cancer, results of genetic testing of the patient himself and his lesion, and his urologist’s philosophy about surveillance. Where a patient lives matters, too, because variations in surveillance levels exist in different geographic areas, domestically and internationally.

“Active surveillance is a strategy of monitoring until it is necessary to be treated. For some people, it is very short, and for others, essentially indefinite,” said Michael Leapman, MD, clinical lead at Yale Cancer Center in New Haven, Connecticut. “While there are differences, I think they are mainly about who is the ideal patient.”

Most studies show that roughly half of men in the United States who go on active surveillance abandon it within 5 years of diagnosis. Rashid Sayyid, MD, a clinical fellow at the University of Toronto, Canada, found in a paper presented to the American Urological Association in 2022 that the number leaving active surveillance increased to nearly two thirds at 10 years.

Peter Carroll, MD, a urologist at the University of California, San Francisco, and a pioneer in the active surveillance in the late 1990s, said the major reason men abandon the strategy is because monitoring reveals the presence of a more aggressive cancer, typically a grade group 2 (Gleason 3 + 4) lesion. But other reasons include anxiety and other emotional distress and upgrades in blood levels of PSA and increases in the rating scale for MRI for the likelihood of the presence of clinically significant prostate cancer.

Laurence Klotz, MD, of the University of Toronto, Toronto, Ontario, who coined the term active surveillance strategy in 1997 and published the first studies in the early 2000s, said it is important to consider when the data on surveillance were collected.

Since 2013, when MRI began to be adopted as a surveillance modality for men with prostate cancer, the dropout rate began declining. The reason? According to Dr. Klotz, MRIs and targeted biopsies result in greater accuracy in staging the disease, determining which patients need to be biopsied, which helps some men avoid being diagnosed to begin with.

Dr. Klotz cited as an example of the emerging change a 2020 study in the Journal of Urology, which found a 24% dropout rate for surveillance at 5 years, 36% at 10 years, and 42% at 15 years in a series of 2664 grade group 1 patients on active surveillance at Memorial Sloan Kettering Cancer Center in New York City from 2000 to 2017.

Dr. Leapman cited a 2023 study in JNCI Cancer Spectrum using the National Cancer Database that found a decline in the percentage of patients who had grade group 1 in biopsies from 45% in 2010 to 25% in 2019.

“There is more judicious use of PSA testing and biopsy in individuals who are more likely to have significant prostate cancer,” Dr. Leapman told this news organization. “And MRI could also play a role by finding more high-grade cancers that would have otherwise been hidden.”

The changing statistics of prostate cancer also may reflect decreases in screening in response to a 2012 statement from the US Preventive Services Task Force advising against PSA testing. The American Cancer Society in January 2023 said that statement could be driving more diagnoses of late-stage disease, which has been surging for the first time in two decades, especially among Black men.

Dr. Sayyid said patients must be selected carefully for active surveillance. And he said urologists should not promise their active surveillance patients that they will avoid treatment. “There are numerous factors at stake that influence the ultimate outcome,” he said.

Progression of Gleason scores is estimated at 1%-2% per year, Dr. Sayyid added. When active surveillance fails in the short to medium term — 5-10 years — the reason usually is that higher-grade cancers with Gleason 3 + 4 or above were initially missed.

Dr. Sayyid said he counsels patients aged 70 years and older differently than those in their 50s, telling younger patients they are more likely to need treatment eventually than the older patients.

Factors that can affect the longevity of active surveillance include the presence or absence of germline mutations and the overall health and life expectancy and comorbidities such as heart disease and diabetes in a given patient, he said.

Urologists hold varying philosophies here, especially involving younger patients and the presence of any level of Gleason 4 cancer.

William Catalona, MD, of Northwestern University Feinberg School of Medicine in Chicago, Illinois, who developed the concept of mass screening with PSA testing, originally opposed active surveillance. In recent years, he has modified his views but still takes a more conservative approach.

“I consider active surveillance a foolish strategy or, at best, a short-term strategy for young, otherwise healthy men, especially those having any Gleason pattern 4 disease.”

“More than half will ultimately convert to active treatment, some too late, and will require multiple treatments with multiple side effects. Some will develop metastases, and some will die of prostate cancer.”

Dr. Sayyid takes a more liberal approach. “I would counsel an eligible patient considering active surveillance that at the current time, I see no strong reason why you should be subjected to treatment and the associated side effects,” he said. “And as long as your overall disease ‘state’ [the combination of grade, volume, PSA, and imaging tests] remains relatively stable, there should be no reason for us to ‘jump ship’. In my practice, another term for active surveillance is ‘active partnership’ — working together to decide if this is a sprint or a lifelong marathon.”

TOPLINE:

Imposing a new prior authorization requirement increased the likelihood that older patients with cancer will delay or stop filling their prescription for oral anticancer drugs, a new study showed.

METHODOLOGY:

• Prior authorization requirements, especially in oncology, continue to increase, but how these policies affect patients’ access to care remains less clear.
• Researchers analyzed Medicare Part D claims from 2010 to 2020 to assess the effects of prior authorization changes on prescriptions fills for 1 of 11 oral anticancer drugs.
• The study included 2495 patients filling a prescription for these medications prior to their health plan imposing a new prior authorization policy and 22,641 patients filling prescriptions for the same drugs with no change in prior authorization policy (control).
• Beneficiaries had at least three 30-day fills in the 120 days before the new prior authorization policy was established on January 1 and continued to be enrolled in the same plan 120 days after the policy change.
• The researchers focused on how often patients discontinued their therapy within 120 days following a prior authorization policy change, as well as the time to fill a prescription after this change.

TAKEAWAY:

• Patients subjected to a new prior authorization policy on an established drug had a sevenfold higher likelihood of stopping the drug within 120 days than those who had no change in prior authorization requirements (adjusted odds ratio, 7.1).
• The adjusted probability of discontinuing an oral cancer regimen within 120 days after an index date of January 1 (when most health plan policy changes occur) was 5.8% for those with a new prior authorization policy vs 1.4% for the control group.
• A new prior authorization requirement was also associated with an average 10-day delay to refill the first prescription following the policy change (P < .001).
• The probability of a delay of more than 30 days was 22% after a policy change vs 7% after no policy change.

IN PRACTICE:

“Our results suggest concerns about delayed and foregone care related to prior authorization are warranted,” the authors said. Overall, this study found that “prior authorization wasted time and undermined the policy priorities of access to care and oral anticancer drug adherence for patients who were regular users of a particular medication.”

SOURCE:

The study by Michael Anna Kyle, PhD, RN, and Nancy Keating, MD, MPH, with Harvard Medical School, Boston, was published online in the Journal of Clinical Oncology.

LIMITATIONS:

The study did not look at patients starting new oral anticancer drugs, which may come with more complex prior authorization processes and create more significant access issues. The results are also limited to patients taking 1 of 11 oral anticancer agents in Medicare Part D.

DISCLOSURES:

Funding for the study was provided by the National Cancer Institute. The authors reported no relevant conflicts of interest.

Mark Lewis, MD, saw the pain in his patient’s body. The man’s gastrointestinal tumor had metastasized to his bones. Even breathing had become agonizing.

It was a Friday afternoon. Dr. Lewis could see his patient would struggle to make it through the weekend without some pain relief.

When this happens, “the clock is ticking,” said Dr. Lewis, director of gastrointestinal oncology at Intermountain Health in Salt Lake City, Utah. “A patient, especially one with more advanced disease, only has so much time to wait for care.”

Dr. Lewis sent in an electronic request for an opioid prescription to help ease his patient’s pain through the weekend. Once the prescription had gone through, Dr. Lewis told his patient the medication should be ready to pick up at his local pharmacy.

Dr. Lewis left work that Friday feeling a little lighter, knowing the pain medication would help his patient over the weekend.

Moments after walking into the clinic on Monday morning, Dr. Lewis received an unexpected message: “Your patient is in the hospital.”

The events of the weekend soon unfolded.

Dr. Lewis learned that when his patient went to the pharmacy to pick up his pain medication, the pharmacist told him the prescription required prior authorization.

The patient left the pharmacy empty-handed. Hours later, he was in the emergency room (ER) in extreme pain — the exact situation Dr. Lewis had been trying to avoid.

Dr. Lewis felt a sense of powerlessness in that moment.

“I had been left in the dark,” he said. The oncologist-patient relationship is predicated on trust and “that trust is eroded when I can’t give my patients the care they need,” he explained. “I can’t stand overpromising and underdelivering to them.”

Dr. Lewis had received no communication from the insurer that the prescription required prior authorization, no red flag that the request had been denied, and no notification to call the insurer.

Although physicians may need to tread carefully when prescribing opioids over the long term, “this was simply a prescription for 2-3 days of opioids for the exact patient who the drugs were developed to benefit,” Dr. Lewis said. But instead, “he ended up in ER with a pain crisis.”

Prior authorization delays like this often mean patients pay the price.

“These delays are not trivial,” Dr. Lewis said.

A recent study, presented at the ASCO Quality Care Symposium in October, found that among 3304 supportive care prescriptions requiring prior authorization, insurance companies denied 8% of requests, with final denials taking as long as 78 days. Among approved prescriptions, about 40% happened on the same day, while the remaining took anywhere from 1 to 54 days.

Denying or delaying necessary and cost-effective care, even briefly, can harm patients and lead to higher costs. A 2022 survey from the American Medical Association found that instead of reducing low-value care as insurance companies claim, prior authorization often leads to higher overall use of healthcare resources. More specifically, almost half of physicians surveyed said that prior authorization led to an ER visit or need for immediate care.

In this patient’s case, filling the opioid prescription that Friday would have cost no more than $300, possibly as little as $30. The ER visit to manage the patient’s pain crisis costs thousands.

The major issue overall, Dr. Lewis said, is the disconnect between the time spent waiting for prior authorization approvals and the necessity of these treatments. Dr. Lewis says even standard chemotherapy often requires prior authorization.

“The currency we all share is time,” Dr. Lewis said. “But it often feels like there’s very little urgency on insurance company side to approve a treatment, which places a heavy weight on patients and physicians.”

“It just shouldn’t be this hard,” he said.

“I had been left in the dark,” he said. The oncologist-patient relationship is predicated on trust and “that trust is eroded when I can’t give my patients the care they need,” he explained. “I can’t stand overpromising and underdelivering to them.”

Dr. Lewis had received no communication from the insurer that the prescription required prior authorization, no red flag that the request had been denied, and no notification to call the insurer.

Although physicians may need to tread carefully when prescribing opioids over the long term, “this was simply a prescription for 2-3 days of opioids for the exact patient who the drugs were developed to benefit,” Dr. Lewis said. But instead, “he ended up in ER with a pain crisis.”

Prior authorization delays like this often mean patients pay the price.

“These delays are not trivial,” Dr. Lewis said.

A recent study, presented at the ASCO Quality Care Symposium in October, found that among 3304 supportive care prescriptions requiring prior authorization, insurance companies denied 8% of requests, with final denials taking as long as 78 days. Among approved prescriptions, about 40% happened on the same day, while the remaining took anywhere from 1 to 54 days.

Denying or delaying necessary and cost-effective care, even briefly, can harm patients and lead to higher costs. A 2022 survey from the American Medical Association found that instead of reducing low-value care as insurance companies claim, prior authorization often leads to higher overall use of healthcare resources. More specifically, almost half of physicians surveyed said that prior authorization led to an ER visit or need for immediate care.

In this patient’s case, filling the opioid prescription that Friday would have cost no more than $300, possibly as little as $30. The ER visit to manage the patient’s pain crisis costs thousands.

The major issue overall, Dr. Lewis said, is the disconnect between the time spent waiting for prior authorization approvals and the necessity of these treatments. Dr. Lewis says even standard chemotherapy often requires prior authorization.

“The currency we all share is time,” Dr. Lewis said. “But it often feels like there’s very little urgency on insurance company side to approve a treatment, which places a heavy weight on patients and physicians.”

“It just shouldn’t be this hard,” he said.

Mark Lewis, MD, saw the pain in his patient’s body. The man’s gastrointestinal tumor had metastasized to his bones. Even breathing had become agonizing.

It was a Friday afternoon. Dr. Lewis could see his patient would struggle to make it through the weekend without some pain relief.

When this happens, “the clock is ticking,” said Dr. Lewis, director of gastrointestinal oncology at Intermountain Health in Salt Lake City, Utah. “A patient, especially one with more advanced disease, only has so much time to wait for care.”

Dr. Lewis sent in an electronic request for an opioid prescription to help ease his patient’s pain through the weekend. Once the prescription had gone through, Dr. Lewis told his patient the medication should be ready to pick up at his local pharmacy.

Dr. Lewis left work that Friday feeling a little lighter, knowing the pain medication would help his patient over the weekend.

Moments after walking into the clinic on Monday morning, Dr. Lewis received an unexpected message: “Your patient is in the hospital.”

The events of the weekend soon unfolded.

Dr. Lewis learned that when his patient went to the pharmacy to pick up his pain medication, the pharmacist told him the prescription required prior authorization.

The patient left the pharmacy empty-handed. Hours later, he was in the emergency room (ER) in extreme pain — the exact situation Dr. Lewis had been trying to avoid.

TOPLINE:

Women with estrogen receptor (ER)–positive, human epidermal growth factor receptor 2 (HER2)–negative invasive lobular carcinoma who are treated with endocrine therapy do not derive any additional survival benefit from neoadjuvant or adjuvant chemotherapy.

METHODOLOGY:

• Studies evaluating the long-term effects of chemotherapy in patients with invasive lobular carcinoma are limited and often “show inconclusive results,” the authors explained.
• Female patients diagnosed with ER-positive, HER2-negative invasive lobular carcinoma who received endocrine therapy were identified from the breast cancer database at Erasmus Medical Center, Rotterdam, the Netherlands.
• Linked information on patient and tumor characteristics, vital status, and treatment were then obtained from the Netherlands Cancer Registry.
• Patients also had to have an indication for chemotherapy based on lymph node status, tumor size, histologic tumor grade, and hormone receptor status, in line with national guidelines.
• Among 716 patients with ER-positive, HER2-negative invasive lobular carcinoma, 520 who had an indication for chemotherapy were included. Of those, 379 received chemotherapy and 141 did not.

TAKEAWAY:

• Patients who received chemotherapy were younger at diagnosis than those who did not (51 vs 61 years), had an earlier average year of diagnosis (2010 vs 2015), and had longer follow-up (7.8 years vs 5.2 years).
• Chemotherapy recipients were more likely to have T3+ disease (33% vs 14%) and positive lymph node involvement (80% vs 49%), and less likely to undergo breast-conserving surgery (31% vs 43%).
• Researchers, however, found no difference between the chemotherapy and no-chemotherapy groups in terms of recurrence-free survival (hazard ratio [HR], 1.20; 95% CI, 0.63-2.31), breast cancer–specific survival (HR, 1.24; 95% CI, 0.60-2.58), and overall survival (HR, 0.97; 95% CI, 0.56-1.66) after adjustment for confounders.

IN PRACTICE:

The authors “observed no evidence for added value of chemotherapy” for ER-positive, HER2-negative invasive lobular carcinoma who received endocrine therapy. “In view of the adverse effects of chemotherapy, our study takes an important step in answering a valuable question from the patient’s perspective,” the researchers wrote.

SOURCE:

The study, conducted by Bernadette A.M. Heemskerk-Gerritsen, PhD, from Erasmus Medical Center Cancer Institute, Rotterdam, the Netherlands, was published in Cancer on November 20, 2023.

LIMITATIONS:

The retrospective design means that there is a risk for residual confounding from factors not recorded in the database. The researchers believe that some patients did not receive chemotherapy owing to having comorbidities or patient preference, which could have influenced the results. Moreover, the duration of endocrine therapy was not recorded.

SAN ANTONIO — Axillary lymph node dissection may be unnecessary if breast cancer patients with one or two positive sentinel lymph nodes plan to have adjuvant nodal radiation, according to a major Scandinavian trial presented at the San Antonio Breast Cancer Symposium.

“It means that you don’t need to dissect the axilla if you” are going to “radiate the axilla.” “For the U.S., that’s the conclusion because there are still centers that do both, and that’s out,” lead investigator Jana de Boniface, MD, PhD, a breast cancer surgeon at the Karolinska Institutet, Stockholm, said in an interview.

The study added to a persistent theme at this year’s meeting, protecting breast cancer patients from doing too much and causing unnecessary harm. Some even wondered if 5 years of endocrine therapy is necessary.

Dr. Boniface shared her thoughts after presenting the Scandinavian trial, SENOMAC, which she led.

SENOMAC randomized 1,204 patients with one or two positive sentinel lymph nodes to axillary dissection; 1,335 with the same finding were randomized to no dissection.

Subjects had clinically T1-3, N0 primary breast cancer. About 89% in both arms went on to adjuvant radiation, including nodal radiation, and almost all also went on to systemic therapy, which included endocrine therapy in over 90%. Only about 2% of subjects had neoadjuvant therapy.

At a median follow-up of nearly 4 years, recurrence-free survival was virtually identical in both groups, with 8% of patients in the dissection arm and 7.1% in the no-dissection group having recurrences. Estimated 5-year recurrence-free survival was just shy of 90% in both groups. Skipping dissection was strongly non-inferior to having one (P < .001).

SENOMAC “clearly shows that you don’t need to dissect the axilla if you have one to two positive sentinel lymph nodes” so long as patients have adjuvant nodal radiation. Recurrence-free survival “curves practically overlap, and we cannot see any difference between the two groups,” Dr. Boniface said.

Meanwhile, the dissection group fared worse on patient reported outcomes. Overall survival outcomes, the primary endpoint of the trial, are expected within 2 years.

The goal of the trial, the largest to date to look into the issue, was to fill gaps in the literature. Similar outcomes were reported around a decade ago in patients with low sentinel lymph node burdens, but the extensive exclusion criteria raised questions about general applicability.

In contrast, SENOMAC was widely inclusive. Over a third of patients had mastectomies, over a third had sentinel lymph node extracapsular extension, almost 6% had T3 disease, almost 20% had lobular carcinoma, 40% were 65 years or older, and tumors were as large as 15.5 cm.

The findings held regardless of those and other factors on subgroup analyses, including estrogen receptor and HER2 status and the number of additional positive nodes retrieved in the dissection group.

Andrea V. Barrio, MD, the study discussant and a breast cancer surgeon at Memorial Sloan Kettering Cancer Center, New York, agreed with the message from SENOMAC.

“Based on this, ALND [axillary lymph node dissection] should not be considered standard in patients with clinical T1-3, N0 breast cancer with one to two positive sentinel nodes, with or without microscopic extracapsular extension, undergoing lumpectomy or mastectomy,” provided nodal adjuvant radiotherapy is indicated, she said.

Although adjuvant nodal radiation for patients with one to three positive sentinel nodes is standard of care in Denmark and Sweden, where most of the patients in SENOMAC were located, practices vary widely in the United States. If adjuvant radiation isn’t used, “then ALND [is still] indicated,” Dr. Barrio said, but in either case, “only one is needed.”

In keeping with the de-escalation theme at the 2023 symposium, both Dr. Boniface and Dr. Barrio noted that trials are now underway to find patients who can avoid any axillary treatment at all if they have just one or two positive sentinel lymph nodes.

Preoperative axillary ultrasound was mandatory in SENOMAC and patients with non-palpable suspicious axillary lymph nodes were enrolled.

Thirty-six were positive on fine needle aspiration and randomized into the study, but when asked, Dr. Boniface didn’t have the data immediately at hand on how they fared.

The work was funded by the Swedish Research Council, Nordic Cancer Union, and others. Dr. Boniface and Dr. Barrio didn’t have any disclosures.

Healthcare costs for patients undergoing common surgical procedures are significantly higher when the surgery is performed by a male surgeon rather than a female surgeon, data suggested.

A retrospective, population-based cohort study that included more than 1 million adults undergoing any of 25 common surgical procedures found that total healthcare costs assessed at 1 year following surgery were more than $6000 higher when the surgery was performed by a male surgeon. Costs were also higher at 30 and 90 days for patients treated by male surgeons.

“As a male surgeon, I think our results should cause me and my colleagues to pause and consider why this may be,” said lead author Christopher J. D. Wallis, MD, PhD, assistant professor of surgery at the University of Toronto.

“None of us believe that the presence of a Y chromosome in surgeons means there are worse outcomes, it’s just that generally speaking, men and women, as we have known for decades, practice medicine a little differently. Things like communication style, time they spend with their patients, and even things like guideline adherence are different, and understanding how those differences translate into patient outcomes is the goal of this whole body of work,” said Wallis.

The study was published online November 29 in JAMA Surgery.

Explanation Is Elusive

In earlier work, Dr. Wallis and his team reported that patients treated by female surgeons had a small but statistically significant decrease in 30-day mortality, were less likely to be readmitted to the hospital, and had fewer complications than those treated by male surgeons. In another study, they found worse outcomes among female patients treated by male surgeons.

In the current study, the researchers examined the association between surgeon sex and healthcare costs among patients undergoing various surgical procedures, including coronary artery bypass grafting, appendectomy, hysterectomy, anterior spinal decompression, and knee replacement. They included all adult patients who underwent these procedures at hospitals in Ontario, Canada, between January 2007 and December 2019 in their analysis.

The study sample included 1,165,711 patients. Of this group, 151,054 patients were treated by a female surgeon, and 1,014,657 were treated by a male surgeon.

After adjusting for patient-, surgeon-, anesthesiologist-, and hospital-related factors, they found that 1-year total healthcare costs were $24,882 for patients treated by male surgeons vs $18,517 for patients treated by female surgeons. Healthcare costs were also higher at 30 days (adjusted absolute difference, $3115) and at 90 days (adjusted absolute difference, $4228).

“This translates into a 9%-10% higher risk of costs with male surgeons compared with women surgeons at these time points,” said Dr. Wallis.

“This study cannot provide a specific answer as to why these differences are occurring,” Dr. Wallis said.

“We are currently undertaking more research to better understand the reasons. Our previous studies have shown that patients treated by male physicians have higher rates of death, readmission, and complications. Managing these adverse postoperative events is costly and likely contributes to these differences. Given the size of our study and similar training pathways, we do not think there are technical differences between male and female surgeons. Rather, we are hypothesizing that there may be differences in how physicians practice, make decisions, and consult with patients,” he said.

Ultimately, Dr. Wallis said he would like his research to prompt “a moment of introspection” among his surgical colleagues.

“Hopefully, these data will provide the impetus for further efforts to make surgery, and medicine in general, a field that is welcoming to women,” he said.

Potential Confounding Factors

This study expands the evidence suggesting significant practice differences between male and female surgeons, Ursula Adams, MD, a resident; Caprice C. Greenberg, MD, MPH, chair; and Jared Gallaher, MD, MPH, adjunct assistant professor, all from the Department of Surgery at the University of North Carolina in Chapel Hill, wrote in an accompanying editorial.

They cautioned, however, that “there are many potential confounding factors and possible explanatory mechanisms associated with surgeon sex that make it challenging to untangle influences on costs. Sex may be an easily captured data point, but is understanding the mechanism by which it affects cost the right next step? Surgeons control how and where they practice; they do not have control over their own demographics.”

The editorialists added that while recruiting and retaining women in surgery is important, it is not a solution to controlling costs.

“We must provide surgeons with better data to understand how practice approach and decisions affect cost and support for practice improvement. Only with these insights will we ensure patients of male surgeons receive care that is just as cost-effective as that provided by female surgeons, while also helping to bend the cost curve and improve the quality of surgical care,” they concluded.

‘Admirable’ Data Use

Commenting on the findings, Oluwadamilola “Lola” Fayanju, MD, chief of breast surgery at Penn Medicine in Philadelphia, said, “It is interesting that the study was performed in Canada with its different healthcare system.” Dr. Fayanju did not participate in the study.

“They used administrative data from a national database, and it is admirable that they were able to do that. These data allow us to make large-scale geographical assessments, although they are subject to errors and unmeasured confounders,” said Dr. Fayanju.

Women surgeons may do things that result in better outcomes, she suggested. “In this study, the women were younger and so perhaps were more up to date. They might have optimized management of their patients in the pre-op phase, including better patient selection, which led to better costs. Or in the post-op phase, they might have made themselves readily accessible. For instance, I remove all barriers about getting in touch with me, and I tell my students to make sure the patient can reach you easily,” said Dr. Fayanju.

Healthcare costs for patients undergoing common surgical procedures are significantly higher when the surgery is performed by a male surgeon rather than a female surgeon, data suggested.

A retrospective, population-based cohort study that included more than 1 million adults undergoing any of 25 common surgical procedures found that total healthcare costs assessed at 1 year following surgery were more than $6000 higher when the surgery was performed by a male surgeon. Costs were also higher at 30 and 90 days for patients treated by male surgeons.

“As a male surgeon, I think our results should cause me and my colleagues to pause and consider why this may be,” said lead author Christopher J. D. Wallis, MD, PhD, assistant professor of surgery at the University of Toronto.

“None of us believe that the presence of a Y chromosome in surgeons means there are worse outcomes, it’s just that generally speaking, men and women, as we have known for decades, practice medicine a little differently. Things like communication style, time they spend with their patients, and even things like guideline adherence are different, and understanding how those differences translate into patient outcomes is the goal of this whole body of work,” said Wallis.

The study was published online November 29 in JAMA Surgery.

Explanation Is Elusive

In earlier work, Dr. Wallis and his team reported that patients treated by female surgeons had a small but statistically significant decrease in 30-day mortality, were less likely to be readmitted to the hospital, and had fewer complications than those treated by male surgeons. In another study, they found worse outcomes among female patients treated by male surgeons.

In the current study, the researchers examined the association between surgeon sex and healthcare costs among patients undergoing various surgical procedures, including coronary artery bypass grafting, appendectomy, hysterectomy, anterior spinal decompression, and knee replacement. They included all adult patients who underwent these procedures at hospitals in Ontario, Canada, between January 2007 and December 2019 in their analysis.

The study sample included 1,165,711 patients. Of this group, 151,054 patients were treated by a female surgeon, and 1,014,657 were treated by a male surgeon.

After adjusting for patient-, surgeon-, anesthesiologist-, and hospital-related factors, they found that 1-year total healthcare costs were $24,882 for patients treated by male surgeons vs $18,517 for patients treated by female surgeons. Healthcare costs were also higher at 30 days (adjusted absolute difference, $3115) and at 90 days (adjusted absolute difference, $4228).

“This translates into a 9%-10% higher risk of costs with male surgeons compared with women surgeons at these time points,” said Dr. Wallis.

“This study cannot provide a specific answer as to why these differences are occurring,” Dr. Wallis said.

“We are currently undertaking more research to better understand the reasons. Our previous studies have shown that patients treated by male physicians have higher rates of death, readmission, and complications. Managing these adverse postoperative events is costly and likely contributes to these differences. Given the size of our study and similar training pathways, we do not think there are technical differences between male and female surgeons. Rather, we are hypothesizing that there may be differences in how physicians practice, make decisions, and consult with patients,” he said.

Ultimately, Dr. Wallis said he would like his research to prompt “a moment of introspection” among his surgical colleagues.

“Hopefully, these data will provide the impetus for further efforts to make surgery, and medicine in general, a field that is welcoming to women,” he said.

Potential Confounding Factors

This study expands the evidence suggesting significant practice differences between male and female surgeons, Ursula Adams, MD, a resident; Caprice C. Greenberg, MD, MPH, chair; and Jared Gallaher, MD, MPH, adjunct assistant professor, all from the Department of Surgery at the University of North Carolina in Chapel Hill, wrote in an accompanying editorial.

They cautioned, however, that “there are many potential confounding factors and possible explanatory mechanisms associated with surgeon sex that make it challenging to untangle influences on costs. Sex may be an easily captured data point, but is understanding the mechanism by which it affects cost the right next step? Surgeons control how and where they practice; they do not have control over their own demographics.”

The editorialists added that while recruiting and retaining women in surgery is important, it is not a solution to controlling costs.

“We must provide surgeons with better data to understand how practice approach and decisions affect cost and support for practice improvement. Only with these insights will we ensure patients of male surgeons receive care that is just as cost-effective as that provided by female surgeons, while also helping to bend the cost curve and improve the quality of surgical care,” they concluded.

‘Admirable’ Data Use

Commenting on the findings, Oluwadamilola “Lola” Fayanju, MD, chief of breast surgery at Penn Medicine in Philadelphia, said, “It is interesting that the study was performed in Canada with its different healthcare system.” Dr. Fayanju did not participate in the study.

“They used administrative data from a national database, and it is admirable that they were able to do that. These data allow us to make large-scale geographical assessments, although they are subject to errors and unmeasured confounders,” said Dr. Fayanju.

Women surgeons may do things that result in better outcomes, she suggested. “In this study, the women were younger and so perhaps were more up to date. They might have optimized management of their patients in the pre-op phase, including better patient selection, which led to better costs. Or in the post-op phase, they might have made themselves readily accessible. For instance, I remove all barriers about getting in touch with me, and I tell my students to make sure the patient can reach you easily,” said Dr. Fayanju.

The study was supported by ICES, which is funded by an annual grant from the Ontario Ministry of Health and the Ministry of Long-Term Care, and the Data Sciences Institute at the University of Toronto.

TOPLINE:

Regular moderate to vigorous physical activity predicts larger brain size in key regions, including gray and white matter and the hippocampus, new data suggest. 

METHODOLOGY: 

• The potential neuroprotective effects of regular physical activity on brain structure are unclear despite reported links between physical activity and reduced dementia risk. 
• To investigate, researchers analyzed MRI brain scans from 10,125 healthy adults (mean age, 53 years; 52% male) who self-reported their level of physical activity.
• Moderate to vigorous physical activities, defined as those increasing respiration and pulse rate for at least 10 continuous minutes, was modeled with brain volumes, adjusting for covariates.
• The threshold for defining physically active (vs nonactive) adults was intentionally set at 2.5 days per week, a level far lower than current guidelines.

TAKEAWAY:

• Three quarters of the cohort reported engaging in moderate to vigorous physical activity approximately 4 days per week. 
• Physically active adults tended to be younger, with a higher proportion of White individuals, and with lower rates of hypertension and type 2 diabetes. 
• After adjusting for multiple factors, increased days of moderate to vigorous activity correlated with larger normalized brain volume in multiple regions including total gray matter; white matter; hippocampus; and frontal, parietal, and occipital lobes. 

IN PRACTICE: 

“We found that even moderate levels of physical activity, such as taking fewer than 4,000 steps a day, can have a positive effect on brain health. This is much less than the often-suggested 10,000 steps, making it a more achievable goal for many people,” co-author David Merrill, MD, with Pacific Brain Health Center, Santa Monica, California, said in a statement. 

SOURCE: 

The study, with first author Cyrus A. Raji, MD, PhD, Washington University School of Medicine, St. Louis, was published online in the Journal of Alzheimer’s Disease.

LIMITATIONS: 

Participants self-reported physical activity in the past 2 weeks, which does not reflect a lifetime of activity levels. The correlation identified between physical activity and brain volumes may not be solely attributable to physical activity alone. 

DISCLOSURES: 

The study received funding from several health centers and foundations. Dr. Raji consults for Brainreader ApS, Neurevolution LLC, Apollo Health, Voxelwise Imaging Technology, and Pacific Neuroscience Foundation and is an editorial board member of the Journal of Alzheimer’s Disease but was not involved in the peer-review process.

TOPLINE:

Patients aged 50 years or older with clinically apparent Helicobacter pylori infection (CAHPI) have an 11% increased risk for Alzheimer’s disease (AD), results of a large and lengthy population-based study suggest.

METHODOLOGY: 

• Researchers identified all cases with a first-time diagnosis of AD and matched each AD case to up to 40 AD-free control cases on the basis of age, sex, cohort entry date, and duration of follow-up.
• The exposure of interest was CAHPI, defined based on an algorithm using clinical guidelines and recommendations on the management of H pylori (HP) infection, with researchers focusing on infected individuals presenting with symptoms or developing serious complications from the infection.
• Researchers performed several sensitivity analyses, which included repeating the primary analysis using alternate lag periods, restricting the cohort to participants with AD (not vascular, alcoholic, and unspecified dementia), and using salmonellosis, an infection not previously associated with AD, as a negative control exposure.

TAKEAWAY: 

• Compared with no exposure to CAHPI, exposure to CAHPI was associated with a moderately increased risk for AD (odds ratio [OR], 1.11; 95% CI, 1.01-1.21), with no major effect modification by demographics or socioeconomic status.
• The increased risk peaked 7.3-10.8 years after CAHPI onset (OR, 1.24; 95% CI, 1.05-1.47) before decreasing.
• Sensitivity analyses yielded findings that were overall consistent with those of the primary analysis.
• The analysis with salmonellosis as a negative control exposure showed no association with the risk for AD (OR, 1.03; 95% CI, 0.82-1.29).

IN PRACTICE:

“These results support the notion of HP infection as a potential modifiable risk factor of AD” and “pave the way for future randomized controlled trials that would assess the impact and cost-effectiveness of population-based targeted interventions such as individualized HP eradication programs, on the development of AD,” the authors write.

SOURCE:

The study was conducted by Antonios Douros, Department of Medicine, and Department of Epidemiology, Biostatistics, and Occupational Health, McGill University, Montreal, Quebec, Canada, and colleagues. It was published online in Alzheimer’s & Dementia.

LIMITATIONS:

Given the observational nature of the study, residual confounding is possible. Because the exposure definition was on the basis of CAHPI recorded by general practitioners, exposure misclassification due to symptomatic patients not seeking primary care is possible, as is outcome misclassification. The authors can’t rule out the possibility of an association between asymptomatic H pylori infection and AD risk.

DISCLOSURES:

The study received funding from the Canadian Institutes of Health Research. Douros has no relevant conflicts of interest; see paper for disclosures of other authors.

Pauline Anderson has disclosed no relevant financial relationships.

The arteries of members of an indigenous community in the Bolivian Amazon, dubbed “the world’s healthiest,” have remarkably low rates of coronary atherosclerosis, compared with those of other populations. These arteries recently were found to be exceptionally elastic and to age more gradually, according to a study presented at the annual scientific sessions of the American Heart Association.

The lead researcher, Michael Gurven, PhD, director of the Integrative Anthropological Sciences Unit at the University of California, Santa Barbara, said in an interview that the study “provides additional evidence that lifestyle modifications can improve arterial health.”

An Ancient Lifestyle

The study focused on the Tsimané or Chimane people, an indigenous community in Bolivia that sustains itself through ancestral practices like slash-and-burn agriculture (mainly involving plantains, rice, sweet cassava, and maize), river fishing, hunting neotropical mammals, and gathering seasonal fruits, honey, and nuts. They are inactive only 10% of their daily time and adhere to a low-fat, low-processed carbohydrate diet.

Over the past decade, numerous studies in this community documented a lower prevalence of arterial hypertension, atrial fibrillation, type 2 diabetes, obesity, smoking, sedentary lifestyle, and more recently, minimal cognitive dysfunction and dementia.

In 2017, Dr. Gurven led a cross-sectional study showing that Tsimané individuals over age 40 years had very low coronary artery calcium scores, which are a marker for coronary atherosclerosis. The finding strongly suggests that healthy lifestyle habits genuinely work in cardiovascular prevention. The mechanisms involved and their evolution with age needed further exploration, however.

The new research, led by Dr. Gurven’s student Tianyu Cao, delved into arterial elasticity, particularly in the carotid and femoral arteries, as a measure of potential arterial stiffening and atherosclerosis. The study included around 500 adults of both sexes.

Aging and Arterial Elasticity

The findings revealed that Tsimané arteries are less rigid than those in various urban and sedentary populations that have been studied previously. For instance, the elasticity of large and small arteries in 491 Tsimané individuals (average age: 55.3 years) was 57%-86% higher than that observed in adult men and women in the United States in the Multi-Ethnic Study of Atherosclerosis.

Similarly, the carotid-femoral pulse wave velocity, a direct indicator of arterial stiffness, was determined in 89 Tsimané individuals (average age: 53.1 years, 54% women). The average value was 6.34 m/s, which is approximately 25% lower than the average for a healthy Brazilian population aged 35-74 years.

Dr. Gurven noted that Tsimané arteries remain more elastic for a longer period than in other populations. However, by age 70 years, the arteries also start to harden. “In other words, Tsimané cannot indefinitely delay arterial aging,” he said.

“The minimal and delayed increase in arterial stiffness related to age could contribute to the very low observed levels of coronary atherosclerosis and dementia in the Tsimané,” wrote the researchers.

Pedro Forcada, MD, a cardiologist and professor at the University Austral in Buenos Aires, who was not involved in the study, emphasized the impact of epigenetics on atherosclerosis and accelerated vascular aging. He referred to the SUPERNOVA phenomenon in Europe and Japan, where exceptionally low arterial stiffness characterizes very long-lived individuals.

“This indicates that we must not only understand accelerated vascular aging but also study protective factors. Lifestyle, according to these recent studies, would play a significant role,” he stated.

Dr. Gurven and Dr. Forcada declared no relevant economic conflicts of interest.

Dr. Gurven noted that Tsimané arteries remain more elastic for a longer period than in other populations. However, by age 70 years, the arteries also start to harden. “In other words, Tsimané cannot indefinitely delay arterial aging,” he said.

“The minimal and delayed increase in arterial stiffness related to age could contribute to the very low observed levels of coronary atherosclerosis and dementia in the Tsimané,” wrote the researchers.

Pedro Forcada, MD, a cardiologist and professor at the University Austral in Buenos Aires, who was not involved in the study, emphasized the impact of epigenetics on atherosclerosis and accelerated vascular aging. He referred to the SUPERNOVA phenomenon in Europe and Japan, where exceptionally low arterial stiffness characterizes very long-lived individuals.

“This indicates that we must not only understand accelerated vascular aging but also study protective factors. Lifestyle, according to these recent studies, would play a significant role,” he stated.

Dr. Gurven and Dr. Forcada declared no relevant economic conflicts of interest.

The arteries of members of an indigenous community in the Bolivian Amazon, dubbed “the world’s healthiest,” have remarkably low rates of coronary atherosclerosis, compared with those of other populations. These arteries recently were found to be exceptionally elastic and to age more gradually, according to a study presented at the annual scientific sessions of the American Heart Association.

The lead researcher, Michael Gurven, PhD, director of the Integrative Anthropological Sciences Unit at the University of California, Santa Barbara, said in an interview that the study “provides additional evidence that lifestyle modifications can improve arterial health.”

An Ancient Lifestyle

The study focused on the Tsimané or Chimane people, an indigenous community in Bolivia that sustains itself through ancestral practices like slash-and-burn agriculture (mainly involving plantains, rice, sweet cassava, and maize), river fishing, hunting neotropical mammals, and gathering seasonal fruits, honey, and nuts. They are inactive only 10% of their daily time and adhere to a low-fat, low-processed carbohydrate diet.

Over the past decade, numerous studies in this community documented a lower prevalence of arterial hypertension, atrial fibrillation, type 2 diabetes, obesity, smoking, sedentary lifestyle, and more recently, minimal cognitive dysfunction and dementia.

In 2017, Dr. Gurven led a cross-sectional study showing that Tsimané individuals over age 40 years had very low coronary artery calcium scores, which are a marker for coronary atherosclerosis. The finding strongly suggests that healthy lifestyle habits genuinely work in cardiovascular prevention. The mechanisms involved and their evolution with age needed further exploration, however.

The new research, led by Dr. Gurven’s student Tianyu Cao, delved into arterial elasticity, particularly in the carotid and femoral arteries, as a measure of potential arterial stiffening and atherosclerosis. The study included around 500 adults of both sexes.

Aging and Arterial Elasticity

The findings revealed that Tsimané arteries are less rigid than those in various urban and sedentary populations that have been studied previously. For instance, the elasticity of large and small arteries in 491 Tsimané individuals (average age: 55.3 years) was 57%-86% higher than that observed in adult men and women in the United States in the Multi-Ethnic Study of Atherosclerosis.

Similarly, the carotid-femoral pulse wave velocity, a direct indicator of arterial stiffness, was determined in 89 Tsimané individuals (average age: 53.1 years, 54% women). The average value was 6.34 m/s, which is approximately 25% lower than the average for a healthy Brazilian population aged 35-74 years.

Dr. Gurven noted that Tsimané arteries remain more elastic for a longer period than in other populations. However, by age 70 years, the arteries also start to harden. “In other words, Tsimané cannot indefinitely delay arterial aging,” he said.

An experimental topical phosphodiesterase 4 (PDE4) inhibitor showed superior efficacy to vehicle in patients with mild to moderate atopic dermatitis (AD) and plaque psoriasis, results from a phase 2a study showed.

PDE4 inhibitors are a promising therapeutic target for inflammatory diseases because “they can increase cyclic adenosine monophosphate levels and subsequently reduce the production of proinflammatory cytokines,” lead study author Lawrence F. Eichenfield, MD, of the dermatology department at the University of California, San Diego, and colleagues wrote. The paper was published online in JAMA Dermatology.

Currently Available Treatments

For plaque psoriasis, the FDA approved the topical PDE4 inhibitor roflumilast in 2022. The oral PDE4 inhibitor apremilast has shown to be effective for plaque psoriasis and is well tolerated, and “it has been associated with gastrointestinal adverse events (AEs) such as nausea and diarrhea,” the researchers wrote.

For AD, crisaborole is the only approved topical PDE4 treatment, and it is associated with application site burning and stinging, they wrote.

An Experimental Alternative

The new study tested a topical PDE4 inhibitor known as PF-07038124, which is being developed by Pfizer. It is designed to be “a potent, oxaborole-based PDE4 inhibitor [that shows] immunomodulatory activity in T-cell–based assays, contributing to inhibition of [interleukin]-4 and IL-13; thus, it could provide therapeutic benefit in the treatment of AD and plaque psoriasis,” the authors wrote.

The phase 2a study was conducted from December 21, 2020, to August 18, 2021. Researchers at 34 sites in four countries randomized 104 patients with mild to moderate AD (70) or plaque psoriasis (34) to receive PF-07038124 as a 0.001% topical ointment or a vehicle only once daily for 6 weeks.

The primary end point was the percent change from baseline in the Eczema Area and Severity Index (EASI) total score among patients with AD and in the Psoriasis Area and Severity Index (PASI) score among patients with plaque psoriasis at week 6. Safety measures of interest included treatment-emergent adverse events.

Overall, the mean age of the 104 patients was 43 years, 52.9%, were women, 3.8% were Asian, 12.5% were Black, and 83.7% were White. Most had moderate disease.

At week 6 in patients with AD, the PF-07038124 group showed statistically significantly greater improvement in the EASI total score, compared with vehicle group (−74.9% vs −35.5% respectively; least squares mean [LSM] difference, −39.4%; 90% CI, −58.8% to−20.1%]; P < .001).

Similarly, at week 6 in patients with plaque psoriasis, the PF-07038124 group demonstrated a significantly greater improvement in the PASI total score, compared with the vehicle group (LSM, −4.8; 90% CI, −6.2 to −3.4] vs 0.1; 90% CI, −1.5 to 1.7), for a difference of −4.9; 90% CI, −7.0 to −2.8; P < .001.

In safety outcomes, treatment-emergent adverse events were reported in 16 people receiving PF-07038124 and 26 people receiving a vehicle. The treatment-related adverse events were reported only in the vehicle groups across all indications, while no patients in the PF-07038124 groups experienced pain or skin reactions at the application sites.

The researchers acknowledged certain limitations of the trial, including its small size and the 6-week treatment period. “Unlike crisaborole, topical PF-07038124 was not associated with application site burning and stinging,” they noted. “To confirm persistence of efficacy and the safety profile of PF-07038124, long-term data should be collected in larger studies.”

Pfizer supported the study. Dr. Eichenfield reported receiving personal fees from Pfizer during the conduct of the study. He also has received grant support from, is consultant to, and/or is a member of the advisory board for many other pharmaceutical companies. Several other study authors reported similar disclosures.
