- Resection of intraductal papillary mucinous neoplasm (IPMN) aims to prevent progression to invasive pancreatic cancer.
- A multinational study evaluated survival rates post-resection for IPMN, focusing on patients without pre-operative signs of cancer.
- Among 2275 patients, 77% underwent preventive pancreatic resection, with 61% resected without prior surveillance.
- Final pathology showed 63% with low-grade dysplasia (LGD), 27% with high-grade dysplasia (HGD), and 10% with T1-staged invasive cancer.
- Estimated 1-year overall survival (OS) rate was 97%, with 5-year OS rates varying by pathology: LGD (97%), HGD (99%), T1a-b (96%), T1c (91%).
- Independent predictors for long-term mortality included age ≥75 (HR 1.97) and T1c versus LGD (HR 8.12).
- The study highlights excellent survival post-resection but questions the benefit of immediate resection for LGD cases.
- Future studies should aim to identify patients who can be safely monitored to avoid unnecessary surgeries.
