Tumor-promoting immune cells retrained to fight most aggressive type of brain cancer


 E-Mail
BOSTON - It s a real-life plot worthy of a classic spy novel: Researchers at Massachusetts General Hospital (MGH), the Dana-Farber Cancer Institute and other Boston-area research centers are turning the tables on glioblastomas, the most devastating and aggressive form of brain cancer, by transforming a type of cell that normally protects tumors and inhibits effective drug therapy into a stone-cold glioblastoma killer.
Glioblastoma, a type of brain tumor, is rapidly fatal: Most patients die within two years of diagnosis despite aggressive therapies such as brain surgery, whole-brain radiation and chemotherapy.
Despite hopes that a class of drugs known as immune checkpoint blockers (ICBs) - drugs that have revolutionized the treatment of patients with malignant melanoma, non-small-cell lung cancer, and other solid tumors - could also benefit patients with glioblastoma, ICBs have not been effective against the disease in clinical trials to date. ....

Potential new treatment strategy for breast cancer cells that have spread to the brain


 E-Mail
BOSTON - New research reveals that when breast cancer cells spread to the brain, they must boost production of fatty acids, the building blocks of fat, in order to survive there. The work, which is published in
Nature Cancer and was led by investigators at Massachusetts General Hospital (MGH) and the Koch Institute of the Massachusetts Institute of Technology (MIT), points to a potential new treatment target for shrinking brain tumors that arise secondary to breast cancer.
Therapies that target the human epidermal growth factor receptor 2 (HER2) have transformed treatment for patients with breast cancer whose tumor cells express HER2, but brain metastases from this disease are typically fatal because they are resistant to anti-cancer therapies that are effective in other locations in the body. This is in part due to the blood-brain barrier that protects the brain against circulating toxins and pathogens, but changes in the cancer cells once they reach the bra ....
