Pro-inflammatory M1 macrophages involved in immune responses accelerate the progression of melanoma through the extracellular vesicles they secrete, a recent study from the University of Eastern Finland shows. The findings were published in Cell Communication and Signaling.
Breast cancer continues to be the leading cause of cancer-related illness and premature death among women worldwide. In 2023, there were an estimated 2.3 million new breast cancer cases and 764,000 deaths, resulting in around 24 million years of healthy life lost due to illness and early mortality.
Over a quarter of healthy years lost to breast cancer are due to six modifiable risk factors, including high red meat intake, tobacco, high blood sugar, and high BMI—offering important opportunities for prevention.
The number of new breast cancer cases worldwide is predicted to rise by a third from 2.3 million in 2023 to over 3.5 million in 2050; and the annual global breast cancer death toll is forecast to increase by 44% from 764,000 to nearly 1.4 million.
The authors say that progress towards ensuring all women have an equal chance to survive breast cancer can only be achieved through a combination of aggressive prevention strategies, ensuring well-functioning health systems capable of early diagnosis and comprehensive treatment, and making cancer services both accessible and affordable to all.
Despite recent advancements in breast cancer treatments, new breast cancer cases in women are predicted to rise by a third globally from 2.3 million in 2023 to more than 3.5 million in 2050. Similarly, yearly deaths from the disease are projected to surge 44%, from around 764,000 to 1.4 million, with disproportionate impact in countries with limited resources, according to a major new analysis from the Global Burden of Disease Study Breast Cancer Collaborators, published in The Lancet Oncology.
A recent integrative analysis of single-cell sequencing and single-cell spatial mapping of lymph node metastasis in breast cancer reveals novel mechanisms of the metabolic-immune interaction that drive the spread of breast cancer. The findings from the study in The American Journal of Pathology, published by Elsevier, offer novel insights into the characteristics of the metastatic tumor microenvironment, providing a foundation for targeted therapeutic strategies.
New research from Memorial Sloan Kettering Cancer Center (MSK) finds the TCA cycle’s waste-management function may present an opportunity against cancer; shows how microplastics impair immune ‘housekeeping’ functions; reveals the way the protein TOX plays different roles in different immune cells; and identifies a new combination approach for treating advanced kidney cancer after immunotherapy.
The findings have implications for treatment. Knowing ahead of time which resistance mechanism a patient’s tumor is likely to implement can guide treatment decisions to prevent or reduce resistance.
