medical news: New Class of Cancer Drugs Could Work in Colon Cancers with Genetic Mutation (PARP inhibitors/MRE11 gene/Lynch Synrome))

15% of colorectal cancers have mutation that responds to PARP inhibitors

Newswise — ANN ARBOR, Mich. — A class of drugs that shows promise in breast and ovarian cancers with BRCA gene mutations could potentially benefit colorectal cancer patients with a different genetic mutation, a new study from the University of Michigan Comprehensive Cancer Center finds.

Working in cell lines from colorectal cancer patients, researchers found that a new class of drugs called PARP inhibitors worked against tumors with mutations in the MRE11 gene.
