Introduction
Surveillance of side-branch intraductal papillary mucinous neoplasms (SB-IPMNs) is crucial for managing pancreatic cysts. This study assesses the long-term outcomes of a structured surveillance strategy.
Key Findings
CR-Progression Rate: Among 1,337 patients, 15.3% experienced clinically relevant progression (CR-progression) over a median follow-up of 6.6 years.
Invasive Cancer Development: Only 1.7% developed invasive cancer, indicating that initial size should not be the sole criterion for surgery.
Survival Rates: Patients with CR-progression who underwent resection showed improved survival rates. However, overall survival was not significantly improved for all patients undergoing resection.
Conclusion
Long-term non-operative surveillance for SB-IPMNs is effective, with a low rate of progression to invasive cancer. Surgery should be reserved for those demonstrating CR-progression. This approach helps avoid unnecessary surgeries and focus on patients at higher risk.
