Almost 20% of breast cancer survivors may experience excess weight gain
2024-06-02
(Press-News.org) BOSTON—Almost one out of five breast cancer survivors may experience weight gain of more than 10%, suggests a study presented Monday at ENDO 2024, the Endocrine Society’s annual meeting in Boston, Mass. A number of factors are associated with excessive weight gain, the researchers found.
Factors associated with more than 10% weight gain included a lower weight, younger age, and more advanced cancer stage at cancer diagnosis; hormone-positive breast cancer; mutations of the BRCA2 gene; undergoing more aggressive breast surgery; and the use of chemotherapy and endocrine therapy, the study found.
“Weight gain after breast cancer diagnosis and treatment is a common concern among survivors and poses a risk factor for breast cancer recurrence,” according to study lead researcher Maria Daniela Hurtado Andrade, M.D., Ph.D., of the Mayo Clinic in Jacksonville, Fla. “In addition to increasing the risk of breast cancer recurrence, weight gain increases the risk of cardiovascular disease. In breast cancer survivors, cardiovascular disease is the leading cause of death after breast cancer itself.”
The goal of the study was to identify which breast cancer survivors are at risk of weight gain during their survivorship. Using a registry of 4,744 breast cancer survivors, the researchers found that over the course of six years after breast cancer diagnosis, weight increased on average by two pounds. While this was only a modest weight gain, they found that 18% of survivors gained more than 10% of their body weight at six years.
“The variables we found to be associated with excess weight gain could be used as predictors of weight gain in this population,” Hurtado Andrade said. “Identifying these patients early in the survivorship course will allow us to institute measures to prevent excess weight gain, thereby improving breast cancer and cardiovascular disease outcomes. Our overarching goal is to promote a healthy longevity in breast cancer survivors.”
Hurtado Andrade is scheduled to speak at the Society's obesity news conference at 9 a.m. Eastern June 2. Register to view the livestream at endomediastream.com.

An immunotherapy drug given before surgery instead of chemotherapy meant that over ten times more patients with a certain genetic profile were cancer free after surgery, according to clinical trial results presented by researchers at UCL and UCLH.
The findings, presented at the American Society of Clinical Oncology (ASCO) Annual Meeting 2024, are interim results from the NEOPRISM-CRC phase II clinical trial assessing whether the immunotherapy drug pembrolizumab can improve outcomes for patients with stage two or stage three MMR deficient/MSI-High bowel cancer.

About The Study: A stepped-care model, with palliative care visits occurring only at key points in patients’ cancer trajectories and using a decrement in quality of life to trigger more intensive palliative care exposure, resulted in fewer palliative care visits without diminishing the benefits for patients’ quality of life. While stepped palliative care was associated with fewer days in hospice, it is a more scalable way to deliver early palliative care to enhance patient-reported outcomes.
Quote from corresponding author Jennifer S. Temel, M.D.:
“This study demonstrates that early palliative ...

BOSTON – A new study led by investigators from Mass General Cancer Center, a founding member of the Mass General Brigham healthcare system, reveals the effectiveness of more scalable ways of delivering palliative care to patients with advanced lung cancer. The findings were highlighted at the American Society of Clinical Oncology’s annual meeting and are published in JAMA.
The study, led by Jennifer S. Temel, MD of the Mass General Cancer Center, assessed the effectiveness of stepped palliative care, in which all patients receive palliative care for their condition, but with a minimum of required contact with a specialty-trained clinician. ...

Berlin, Germany: Differences in socioeconomic status (SES) are known to be linked to differences in the risk of developing disease. While people with lower SES are more likely to develop complex diseases such as diabetes and cardiovascular disease, those with a higher SES are at increased risk of developing certain types of cancer. Using biobank and national register data, researchers from Finland have now found that people with lower SES (educational achievement and occupation) have a greater genetic susceptibility to develop many other complex diseases such as rheumatoid arthritis, lung cancer, depression, and alcohol ...

CHICAGO – While CAR T cell therapy has revolutionized treatment for many blood cancers, including non-Hodgkin lymphoma (NHL), many patients who receive CAR T cell therapy do not experience a long-term remission. For those whose cancers return or become resistant after CAR T cell therapy, the prognosis is poor, with few options left.
A new “armored” form of CAR T cell therapy, developed by Carl June, MD, the Richard W. Vague Professor in Immunotherapy in the Perelman School of Medicine at the University ...

BOSTON—People who have had type 1 diabetes for more than 50 years without kidney complications may still be at substantial risk for heart disease, despite excellent control of blood pressure, cholesterol and blood sugar levels, according to a study presented Saturday at ENDO 2024, the Endocrine Society’s annual meeting in Boston, Mass.
Heart disease is a major cause of death in people with type 1 diabetes, especially in those who develop kidney complications from diabetes.
“As people with type 1 diabetes live longer due to improved medical care, a substantial proportion of these patients survive without kidney complications, but are still at high risk for heart ...

BOSTON—Medications for type 2 diabetes and obesity known as GLP-1 receptor agonists may lower the risk of acute pancreatitis recurrence in people with obesity and those with type 2 diabetes, according to a study presented Saturday at ENDO 2024, the Endocrine Society’s annual meeting in Boston, Mass.
Doctors have been cautious about prescribing these medications in patients with a history of pancreatitis due to the potential risk of worsening the condition – a warning that is included in prescribing information, said lead researcher Mahmoud Nassar, M.D., Ph.D., Department of Medicine ...

BOSTON—Having medical conditions linked to obesity does not impact the total weight loss achieved with the anti-obesity medication tirzepatide, according to an industry-supported study being presented Saturday at ENDO 2024, the Endocrine Society’s annual meeting in Boston, Mass.
Obesity causes or worsens over 200 diseases. It has been widely believed that when patients suffer multiple medical problems, they are not able to lose as much weight as those without medical issues. The new study, funded by tirzepatide maker Eli Lilly Inc., was designed to see if having more obesity-associated ...

“It is well established that people who have excess weight at any point in time have a greater risk of heart attacks and strokes. What was not known was whether it matters for how long someone has been exposed to excess weight,” said Alexander Turchin, M.D., M.S., Director of Quality at the Division of Endocrinology at Brigham & Women’s ...

BOSTON—One year after a prediabetes diagnosis, Asians were more likely to develop diabetes mellitus whereas Black patients were more likely to remain in prediabetes range, highlighting racial disparities in diabetes prevention, according to data presented at ENDO 2024, the Endocrine Society’s annual meeting in Boston, Mass.
“Every year a small proportion of patients with prediabetes will progress to diabetes mellitus with some proportion of patients reverting to normal glucose levels,” said Ewelina Niedzialkowska, M.D., an internal medicine resident at Corewell Health William Beaumont University Hospital, in Royal Oak, Mich. “While diet, lifestyle ...
