OncoMap Gene Sequencing Finds 50 Mutations in Ovarian Tumors : Internal Medicine News



".....The team, testing 203 samples with OncoMap, found mutations of 50 genes in total. Some mutations were in genes previously identified in ovarian cancer, including KRAS, CTNNB1, and PIK3CA. Others were not previously known to occur in this disease, but, importantly, are potential drug targets with existing agents. "It’s not like HER2 in breast cancer where that is found in about 30% of breast cancers – we found many mutations in the ovarian cancer samples and they were infrequent," Dr. Matulonis said in a telephone interview prior to the conference; she noted, however, that OncoMap identified KRAS and PIK3CA mutations as the most common, occurring in about 25% of tumors, and "that was reassuring," as it was in line with expectations..........Dr. Matulonis’ team is now using OncoMap on all new ovarian cancers, including nonserous cancers, diagnosed at Dana-Farber, and she predicted the test will become standard in clinical practice within 6 months to a year..........cont'd
