PIK3CA mutation predicts resistance to breast cancer therapy

Cancer Discov. 2014 Feb;4(2):OF3. doi: 10.1158/2159-8290.CD-NB2013-180. Epub 2013 Dec 19.

Abstract

Women with HER2-postive, hormone receptor-positive breast cancer and one or more mutations in PIK3CA were less likely to benefit from neoadjuvant chemotherapy and HER2-targeted therapies than those without a mutation, according to study results presented on December 12 at the 2013 San Antonio Breast Cancer Symposium in Texas.
