    Breast Cancer Patients Get Early Warning of Faltering Drugs With Blood Test

    A clinical trial found that women could switch drugs without waiting for scans showing cancer progression, which improved their quality of life.Breast cancer patients whose tumors have spread to other parts of their bodies live from scan to scan. Is their treatment working? Or will they learn their cancer is growing again?But a new study sponsored by the drug company AstraZeneca showed that there is an alternative: Instead of waiting for a scan to show that a cancer is growing, it’s possible to find early signs that the cancer is resisting the drugs that were controlling it.To do that, researchers used a blood test to find mutations in cancer cells that let the tumors defy standard treatments. Early detection allowed patients to be switched to a different drug that overcomes the mutated cancer. The result was to keep the cancers in check longer, and allow patients to have more than an extra year without deteriorating quality of life.The study was reported Sunday at the annual meeting of the American Society of Clinical Oncology and published in The New England Journal of Medicine.Breast cancer specialists who were not associated with the study applauded the results, saying blood tests could transform the way they monitor patients.“This is a paradigm change,” said Dr. Mary Disis, professor of medicine and oncology at the University of Washington and the Fred Hutchinson Cancer Center.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

    Exercise Extends Life for People With Cancer, Study Shows

    The trial, in people treated for colon cancer, showed clear evidence that an exercise program lowered the risk of disease recurrence and death.A first-of-its kind study adds powerful new evidence to research showing that exercise improves cancer survival.The study, a randomized controlled trial of nearly 900 patients at 55 cancer centers in six countries, showed that people who participated in a structured exercise program lived longer without their cancer coming back and without the occurrence of new cancers. Participants in the exercise program had a 37 percent lower risk of dying and a 28 percent lower risk of recurrent or new cancer than those in the control group.Earlier research had suggested such a benefit, but the data were from observational studies that did not prove a causal link, experts said.“We now have definitive evidence that exercise is not just an intervention for quality of life and fitness. This is an intervention that improves survival and should be standard of care,” said Dr. Christopher Booth, the senior author of the paper and a professor of oncology at Queen’s University in Canada.The study, which was published Sunday in the New England Journal of Medicine, looked at patients with Stage III or high-risk Stage II colon cancer who received standard surgery and chemotherapy treatment. Researchers randomly assigned these patients to a control group, which received educational materials promoting physical activity and healthy nutrition, or to a treatment group, which also received support from a “physical activity consultant” — a hybrid of personal trainer and life coach — over three years to increase their aerobic exercise and sustain it. Patients could choose a number of activities, such as biking, jogging, swimming or kayaking, but most opted for a brisk walk of 45 minutes four times a week, Dr. Booth said.Eighty percent of patients in the exercise group remained disease-free after five years, compared to 74 percent of patients in the control group. After eight years, the exercise program had prevented one death for every 14 people who participated in the exercise arm of the study.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

    Surgeons Perform First Human Bladder Transplant

    Surgeons in Southern California have performed the first human bladder transplant, introducing a new, potentially life-changing procedure for people with debilitating bladder conditions.The operation was performed earlier this month by a pair of surgeons from the University of California, Los Angeles, and the University of Southern California on a 41-year-old man who had lost much of his bladder capacity from treatments for a rare form of bladder cancer.“I was a ticking time bomb,” the patient, Oscar Larrainzar, said on Thursday during a follow-up appointment with his doctors. “But now I have hope.”The doctors plan to perform bladder transplants in four more patients as part of a clinical trial to get a sense of outcomes like bladder capacity and graft complications before pursuing a larger trial to expand its use.Dr. Inderbir Gill, who performed the surgery along with Dr. Nima Nassiri, called it “the realization of a dream” for treating thousands of patients with crippling pelvic pain, inflammation and recurrent infections.“There is no question: A potential door has been opened for these people that did not exist earlier,” said Dr. Gill, the chairman of the urology department at U.S.C.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

    Why Patients Are Being Forced to Switch to a 2nd-Choice Obesity Drug

    CVS Caremark decided to stop offering Zepbound in favor of Wegovy for weight loss. It’s the latest example of limits imposed by insurance that disrupt treatments for patients.Tens of thousands of Americans will soon be forced by their health insurance to switch from one popular obesity drug to another that produces less weight loss.It is the latest example of the consequences of secret deals between drugmakers and middlemen, known as pharmacy benefit managers, that are hired by employers to oversee prescription coverage for Americans. Employers pay lower drug prices but their workers are blocked from getting competing treatments, a type of insurance denial that has grown much more common in the past decade.One of the largest benefit managers, CVS Health’s Caremark, made the decision to exclude Zepbound in spite of research that found that it resulted in more weight loss than Wegovy, which will continue to be covered.Those research findings, first announced in December, were confirmed in an article published on Sunday in The New England Journal of Medicine. The study involved a large clinical trial comparing the drugs that was funded by Eli Lilly, the maker of Zepbound. Earlier research not financed by Eli Lilly reached similar conclusions.Ellen Davis, 63, of Huntington, Mass., is one of the patients affected by Caremark’s decision. “It feels like the rug is getting pulled out from under my feet,” she said.After taking Zepbound for a year, she has lost 85 pounds and her health has improved, she said. She retired after working for 34 years at Verizon, which hired Caremark for her drug coverage.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

    What Ivermectin Can (and Can’t) Do

    Social media posts have promoted the anti-parasitic drug for cancer and Covid. That has doctors alarmed.At least once a week, someone asks Dr. Skyler Johnson if ivermectin can treat their cancer.Patients have asked about the anti-parasitic drug for years, especially during the pandemic. But in recent months, Dr. Johnson, a radiation oncologist at the University of Utah Huntsman Cancer Institute, has fielded more and more questions about the medication.Exaggerated and inaccurate comments about ivermectin have intensified online lately. Google searches for “ivermectin” hit their highest point in January since a Covid wave in 2022. That month, the actor Mel Gibson appeared on the hit podcast “The Joe Rogan Experience” and said that three friends with Stage 4 cancer recovered after taking ivermectin, among other drugs. Researchers said the podcast, which received 10 million views on YouTube alone, fed into a flood of inaccurate claims and misinformation about the drug’s purported health benefits.At the same time, politicians in several states are promoting legislation that would make it easier for people to obtain ivermectin. The governor of Arkansas signed a bill last week that would enable people to buy it without a prescription. Lawmakers in Georgia, Texas, West Virginia, Alabama, Louisiana and Kentucky have filed, or said they plan to file, similar legislation. A wealth of research has shown the drug does not treat Covid. And there is not evidence to support people taking ivermectin to treat cancer.“I understand that people, a lot of times, want to take health into their own hands — they want to figure things out on their own,” said Krissy Lunz Trujillo, an assistant professor of political science at the University of South Carolina who researches health misinformation. “But that might have really serious consequences.”Dr. Johnson worries that people will forgo traditional cancer treatments for a drug that hasn’t been proven to work. He tells patients that there is no rigorous research showing the anti-parasitic drug cures cancer in humans. Still, he has seen some people with early, treatable tumors turn to the drug, and return months later with cancers that have spread to their lymph nodes, bones and brain.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

    Heart-Valve Patients Should Have Earlier Surgery, Study Suggests

    The results of a new clinical trial have overturned the “wait and see” approach that cardiologists have long favored for symptom-free patients.For decades, people with failing heart valves who nevertheless felt all right would walk out of the cardiologist’s office with the same “wait and see” treatment plan: Come back in six or 12 months. No reason to go under the knife just yet.A new clinical trial has overturned that thinking, suggesting that those patients would be much better off having their valves replaced right away with a minimally invasive procedure.The trial, whose results were published this week in The New England Journal of Medicine, could change the way doctors treat severe aortic stenosis, a narrowing of the valve that controls blood flow from the heart. The disease, which has a prognosis worse than that of most cancers, afflicts more than 3 percent of people ages 65 and older. It is expected to become more common as people live longer.Replacing people’s heart valves, even if they were not yet experiencing any ill effects, appeared to roughly halve their risk of being unexpectedly hospitalized for heart problems over at least two years, the trial found.Patients who were put on the more conservative treatment plan overwhelmingly ended up needing surgery anyway: Roughly 70 percent of them developed symptoms and needed to have their valves replaced within two years, suggesting that the disease worsens more quickly than previously understood.“You may be able to at least prevent that progression and perhaps improve patient outcomes by treating earlier,” said Dr. Gregg Stone, a professor of medicine at the Icahn School of Medicine at Mount Sinai, describing the implications of the trial. The findings, he said, “will have a major effect on practice.”We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

    Francisco Lopera, the ‘Country Doctor’ Who Upended Our Understanding of Dementia

    Francisco Lopera defied rebels, cartels and vampire bats to become a pioneering researcher of Alzheimer’s disease.In 1978, Dr. Francisco Lopera did what recent medical school graduates in Colombia and much of Latin America have long done: He set out for an obligatory year of work in a remote part of the country, where an inexperienced médico rural might be the only physician for miles. Dr. Lopera, who was born in the Andean region of Antioquia and knew mostly mountains and farm life before medical school, carried out his service in the Darién Gap, on the Caribbean coast near Panama.There Dr. Lopera, a groundbreaking Colombian Alzheimer’s researcher who died this week at age 73, treated stabbings, snakebites, complicated births, burns and fevers in a hospital that had electricity for only half the day. On one occasion, he was kidnapped by Marxist guerrillas. Another time, he had to flee gunshots.When I met Dr. Lopera in 2017, to start research on a book about the families with Alzheimer’s that became his life’s work, he told me a story about two young brothers who had died one after the other in his hospital, of unknown causes. Lopera traveled to the family home in a remote jungle clearing, where he discovered that the boys’ surviving siblings had bites on their fingers from vampire bats. He sent the bodies to a pathology lab hours away by boat, and the pathologists confirmed rabies. When the government brought in a rabies expert to investigate, Dr. Lopera joined him.He left that experience — long nights in the rainforest, searching for hidden roosts, engrossed in the natural history of rabies and bats — wanting to become a rabies epidemiologist. But that was not to be. His interests were eclectic and quick to change, and a few years later he became a neurology resident in Medellín.In 1984, Dr. Lopera examined a farmer in his 40s who appeared to have dementia. Dr. Lopera took again the unusual step of traveling to the family home, in a mountain hamlet like the one where he had been born. Not just the farmer had symptoms of dementia, he saw — a brother also appeared to be affected. Dr. Lopera had discovered what would turn out to be the world’s largest family with early-onset Alzheimer’s disease. The family shared a genetic mutation, later nicknamed the paisa mutation, that was unique to their region of Colombia. Dr. Lopera spent the next four decades studying the family’s 6,000 members.Dr. Francisco Lopera, second from right, in Yarumal, Colombia, in 2010, with Oderis Villegas, center, who was showing signs of Alzheimer’s disease at age 50.

    Three MDMA Studies Are Retracted by Scientific Journal

    The journal Psychopharmacology has retracted three papers about MDMA-assisted therapy based on what the publication said was unethical conduct at one of the study sites where the research took place.Several of the papers’ authors are affiliated with Lykos Therapeutics, the drug company whose application for MDMA-assisted therapy to treat post-traumatic stress disorder was rejected last week by the Food and Drug Administration. The company said the research in the retracted papers was not part of its application to the F.D.A. In declining to approve Lykos’s application, the agency cited concerns about missing data and problems with the way the company’s study was designed, according to a statement released by Lykos on Friday.The F.D.A. has asked Lykos to conduct an additional clinical trial of its MDMA-assisted therapy, which would have been the first psychedelic medicine to win approval by federal regulators. Lykos has said it would appeal the decision.The journal retraction was first reported by Stat, the health and medical news website.On Sunday, Lykos said that it disagreed with Psychopharmacology’s decision and that it would file an official complaint with the Committee on Publication Ethics, a nonprofit that sets guidelines for academic publications.“The articles remain scientifically sound and present important contributions to the study of potential treatments for PTSD,” the company said in the statement.The incident cited by Psychopharmacology has been well documented. In 2015, an unlicensed Canadian therapist who took part in the trial engaged in a sexual relationship with a participant after the conclusion of the trial’s dosing sessionsIn civil court documents, the patient, Meaghan Buisson, said she was sexually assaulted by the therapist, Richard Yensen, who at the time was working alongside his wife, a licensed therapist. Mr. Yensen has said the relationship was consensual and initiated by Ms. Buisson. Six months after the final session, she moved from Vancouver to Cortes Island, in British Columbia, where the couple lived, according to court documents. The relationship between patient and practitioner continued for more than a year, the documents said. Professional associations in both Canada and the United States prohibit sexual relationships between psychologists and patients for at least two years after their final session. The incident helped highlight some of the challenges associated with psychedelic medicine, which can render patients especially vulnerable during dosing sessions. For that reason, most clinical trials involving psychedelic compounds require the presence of two mental health professionals. (Lykos’s trials with MDMA require only one of the practitioners to be licensed.)The Multidisciplinary Association for Psychedelic Studies, or MAPS, is the nonprofit that carried out the research and later created Lykos to market its proprietary MDMA-assisted therapy. The association publicly acknowledged the incident in 2019, adding that it had been reported to the F.D.A. and to Canadian health authorities.The company acknowledged on Sunday that it had failed to notify Psychopharmacology about the violations, but it said that the oversight should have been addressed through a correction, not a retraction.
