Germline DNA Sequencing Reveals Novel Mutations Predictive of Overall Survival in a Cohort of Patients with Pancreatic Cancer

PURPOSE: -related tumors may correlate with response to chemotherapy and overall survival (OS) in pancreatic cancer. The frequency of germline mutations has been reported in patients predominantly under the age of 60 or with strong family history. We examine the incidence of deleterious germline mutations and compare the chemotherapy responses and OS in an unselected group of patients with metastatic pancreatic cancer. EXPERIMENTAL DESIGN: = 127 TCGA cohort). Chemotherapy response and OS were determined by review of medical records. RESULTS: = NS) in those mutants initially treated with gemcitabine/nab-paclitaxel. A family history of multiple breast, ovarian, and pancreatic cancers was associated with DDR gene mutations and better survival. CONCLUSIONS: We have identified novel germline mutations that are prognostic for survival in patients with pancreatic cancer. We observe improved survival in patients with DDR gene mutations and worsened survival in patients with deleterious mutations in non-DDR genes.
