Shutting down a gene called PRMT5 stopped metastatic estrogen receptor-positive breast cancer cells from growing after they acquired resistance to a standard therapy known as CDK4/6 inhibitors, UT Southwestern Medical Center researchers showed in a new study.
Patients with leptomeningeal metastasis have historically had few treatment options. Now, researchers from The University of Texas MD Anderson Cancer Center have found a combination of targeted therapies, tucatinib and trastuzumab, plus the chemotherapy drug, capecitabine, may improve symptoms and extend survival in some breast cancer patients with LM.
