Germline susceptibility variants impact clinical outcome and therapeutic strategies for stage III colorectal cancer.

ABSTRACT: Although somatic mutations are the main cause of cancer, underlying germline alterations may affect cancer outcome. There is little information on comprehensive analysis of germline genome sequencing for cancer healthcare strategy. Here we studied the implication of germline cancer-associated variants on cancer counselling and therapeutic strategies by germline whole genome and tumor targeted sequencing. Fifty-five gynecological and 104 colorectal cancer (CRC) patients were enrolled. We identified 22 germline pathogenic variants in 16 cancer-associated genes. Most of them are involved in DNA repair signaling, including MLH1, BRCA1/2, MUTYH, ATM, PMS2, MSH6, BAP1, and FANCA. About 6% of cancer patients presented the secondary findings of germline variants with non-oncogenic impact, mainly o
