Popis: | BACKGROUND & AIMS: Many patients with pancreatic adenocarcinoma (PDAC) carry germline mutations associated with increased risk of cancer. It is not clear whether patients with intraductal papillary mucinous neoplasms (IPMNs), which are precursors to some pancreatic cancers, also carry these mutations. We assessed the prevalence of germline mutations associated with cancer risk in patients with histologically confirmed IPMN. METHODS: We obtained non-tumor tissue from 315 patients with surgically resected IPMNs, from 1997 through 2017, and sequenced 94 genes with variants associated with cancer risk. Mutations associated with increased risk of cancer were identified and compared to individuals from the Exome Aggregation Consortium. RESULTS: We identified 23 patients with a germline mutation associated with cancer risk (7.3%; 95% CI, 4.9%–10.8%). Nine patients had a germline mutation associated with pancreatic cancer susceptibility (2.9% 95% CI, 1.4%–5.4%). More patients with IPMNs carried germline mutations in ATM (P |
