Key clinical point : A prognostic signature including 8 DNA repair-related genes (MDC1, RPA3, MED17, DDB2, SFPQ, XRCC4, CYP19A1, and PARP3) predicted overall survival in breast cancer patients
Major finding : The areas under the curve were for 3-year survival and 5-year survival were 0.717 and 0.772, respectively, in the GSE9893 data set, and 0.691 and 0.718, respectively, in the GSE42568 data set.
Study details : The data come from 1,096 women with breast cancer; gene expression profiles and clinical data were collected from a Chinese health database between October 9, 2019, and February 3, 2020.
Disclosures: The study received no outside funding. The researchers had no financial conflicts to disclose.
