(Press-News.org) Mature nodal T-cell lymphoma is a type of rare and aggressive blood cancer. Limited data make it difficult to identify high-risk patients or tailor treatment strategies, so most patients receive similar care despite differences in disease characteristics and outcomes. A new study led by investigators from PETAL Consortium at the Mass General Brigham Cancer Institute found that among patients who achieved a complete remission after initial chemotherapy treatment, survival was worse for those whose disease relapsed within 12 months of initial treatment, suggesting that alternative strategies are needed to benefit these patients. The results are published in Blood.
“The study suggests that patients whose cancer returns within 12 months could benefit from starting non-chemotherapy treatments earlier in their care,” said senior author Salvia Jain, MD, founder and principal investigator of PETAL Consortium and a hematologist and medical oncologist at the Mass General Brigham Cancer Institute. “Understanding what’s happening at the molecular level in this high-risk group of patients is key to improving their outcomes and moving T-cell lymphoma treatment toward more personalized care.”
The study used data from sites around the world to study patients with this rare form of cancer. The team found that relapse within 12 months consistently and significantly predicted worse survival outcomes, regardless of the type of initial treatment the patients received or their individual risk levels as determined by medical assessments. However, for patients who relapsed within that period, survival was improved when they received targeted therapies rather than chemotherapy as their next line of treatment.
“This was a global effort involving more than 100 investigators and data from patients with nodal T-cell lymphoma across three major research groups–PETAL Consortium (global with U.S. predominance), GELL (Latin America), and LYSARC (Europe),” said lead author Mark Sorial, PharmD, BCOP, a researcher at the Mass General Brigham Cancer Institute and Dana-Farber Cancer Institute. “This collaborative approach allowed us to gather a wealth of data to better understand the complexities of nodal T-cell lymphoma. Our findings shed light on the differences we see in patient outcomes and pave the way for more personalized treatment strategies.”

The American College of Lifestyle Medicine (ACLM) applauds two new Centers for Medicare and Medicaid Services (CMS) models that could significantly reshape the landscape for lifestyle medicine practice and reimbursement.
The first model, The Make America Healthy Again: Enhancing Lifestyle and Evaluating Value-based Approaches Through Evidence (MAHA ELEVATE) for Original Medicare, was announced Thursday, December 11, 2025. The model will provide approximately $100 million to fund three-year cooperative agreements for up to 30 proposals that promote ...
Adolescent and young adult nicotine vaping has become an urgent public health concern, as 2024 marked the first year that nicotine vaping was the most initiated drug. Though vaping is the most common way young people use nicotine, few treatments exist to help those trying to quit. What’s more, a 2022 Drug Alcohol Dependence study reported around half of young people who vape nicotine also use cannabis, though the impact of this dual substance use on treatment outcomes remains unclear. A new clinical trial by investigators from Mass General Brigham found varenicline—a ...
About The Study: In this cross-sectional study, adoption of state-level policies associated with higher Supplemental Nutrition Assistance Program (SNAP) participation was also associated with lower county-level food insecurity rates. Policies that lower barriers to SNAP participation may help address rising food insecurity rates observed in 2022 and 2023.

Researchers at Yale University School of Medicine have identified a way to suppress the daily fluctuations in the activity of key immune cells known as neutrophils. The study, to be published December 12 in the Journal of Experimental Medicine (JEM), suggests that inhibiting these fluctuations could prevent neutrophils from causing excessive tissue damage during daylight hours, a phenomenon that may underlie the fact that heart attacks in the early morning are more damaging than heart attacks suffered at night.
Neutrophils provide the first line of defense against ...
KINGSTON, R.I. – Dec. 5, 2025 – Global human rights are in decline according to the findings of a recent study from researchers at the University of Rhode Island’s Center for Nonviolence and Peace Studies. As governments around the world are increasingly using surveillance or legal pressure to discourage journalists and citizens from criticizing top officials, data shows that the number of state-committed atrocities reached an all-time high in 2022—the most recent data available.
In the United States, ...
Heart attacks that occur at night are less severe than those that strike during the day. A new study from the Centro Nacional de Investigaciones Cardiovasculares (CNIC) explains why. Published in the Journal of Experimental Medicine, the study led by Dr. Andrés Hidalgo’s group at the CNIC shows that neutrophils—a type of white blood cell—have an internal clock that regulates their aggressiveness throughout the day and determines the extent of damage they cause to the heart after a heart attack.
The researchers also developed a pharmacological strategy in experimental models to block the molecular clock in neutrophils, keeping them in a “nighttime” ...
SAN ANTONIO – Using menopausal hormone therapy (MHT) was not associated with an increased risk of breast cancer in women with inherited mutations in the BRCA1 or BRCA2 genes, according to the results of a matched prospective analysis presented at the San Antonio Breast Cancer Symposium (SABCS), held December 9-12, 2025.
Women who inherit a pathogenic mutation in the BRCA1 and BRCA2 genes are advised to follow the recommended guidance to have their ovaries and fallopian tubes removed (a procedure known as bilateral salpingo-oophorectomy) ...
SAN ANTONIO – A mobile health (mHealth) intervention for adolescent and young adult breast cancer survivors that offered tailored support by monitoring electronic patient-reported outcomes (ePROs) significantly improved quality of life and symptoms related to vaginal and arm problems, according to results from a randomized clinical trial presented at the San Antonio Breast Cancer Symposium (SABCS), held December 9-12, 2025.
Incidence of breast cancer in women between the ages of 15 and 39 has risen on average 0.6% each year between 1975 and 2022. “Young adults with breast cancer are more likely to suffer both emotionally and medically ...
