Biological mechanism enabling breast cancer to spread to the brain uncovered

Researchers from the Gray Faculty of Medical and Health Sciences in Tel Aviv, in partnership with researchers in 14 laboratories in Israel, USA, Italy, Germany, Poland, and Austria, have uncovered "a mechanism that allows breast cancer to send metastases to the brain - a highly lethal occurrence for which there is currently no effective treatment."   Following injection of cancer cells with or without functional gene P53, results indicated that "cells with disrupted P53 activity thrived much more." These findings are crucial towards developing new drugs and personalized monitoring for early detection and treatment of brain metastases.

Neoadjuvant immunotherapy and understanding anticancer immunity

 Study results currently being presented at the ESMO Immuno-Oncology Congress (held in London, England, December 10-12, 2025) showcase the rise of neoadjuvant immunotherapy studies "from small investigator-led window-of-opportunity...to standard of care paradigms across various tumour types."  Using triple-negative breast cancer and early-stage non-small cell lung cancer as examples, treating patients before surgery provides "access to living tumour ecosystems responding - or not- to immunotherapy."

Rethinking the limits of tissue-agnostic cancer therapy

A recent editorial published in the ESMO Daily Reporter raises questions about the impact of precision medicine in personalized cancer care, considering that "patients are still largely treated according to the primary organ where their cancer originates."  Tumour-agnostic agents, drugs approved if cancer cells cause gene or protein changes, no matter where in the body the cancer originated, calls for physicians and patients to engage in precision medicine, "a first step toward a common understanding...in which tissue-agnostic development should be preferred to conventional trials."

Increased risk of haematologic malignancies among children and adolescents exposed to radiation from medical imaging

 Findings from Risk of Pediatric and Adolescent Cancer Associated with Medical Imaging (RIC) a cohort study of 3 700 000 children from Canada and the U.S. found a "significant dose-response relation between cumulative radiation dose to bone marrow and haematologic malignancies risk." The RIC study further found that susceptibility of children to radiation-induced cancer is high due to longer life expectancy compared to adults.  In addition, a European EPI-CT study indicates a "50% higher risk among children undergoing two or three CT scans than among those undergoing one scan."

No survival benefit from adding adjuvant chemotherapy to endocrine therapy in older women with a genomic grade index high-risk ER-positive, HER2-negative breast cancer

Findings from ASTER 70s, a phase III randomized superiority study conducted on women 70 years or older "with a genomic grade index (GGI) high-risk oestrogen receptor (ER)-positive, HER2-negative breast cancer" identified no statistically significant effect of adding adjuvant chemotherapy to the prescribed treatment plan.  While the authors od this study admit that more evidence of genomic profiling is needed to determine "whether chemotherapy is necessary for older patents with ER-positive tumours", ASTER 70s has provided little evidence on the benefit of adjuvant chemotherapy for older breast cancer patients.
