Intraductal papillary mucinous neoplasm of pancreas: clinicopathological features and long-term survival after surgical resection

Introduction: Intraductal papillary mucinous neoplasm (IPMN) of pancreas can progress from low grade dysplasia to high grade dysplasia and invasive carcinoma. Methods: in this single center retrospective series we analyze the clinicopathological features and long-term follow up of patients who underwent pancreatic resection for IPMN, from January 2009 to December 2019. Results: 31 patients were diagnosed with IPMN. Nine males and 22 females. The mean age was 67 years. Twenty-seven patients (87%) were symptomatic. Seven patients had main duct IPMN, 11 branch type IPMN and 13 mixed type IPMN. High-risk stigmata were found in 20 patients (64.5%) and worrisome features in 10 patients (32.2%). Thirteen patients (41.9%) had an associated invasive carcinoma, 4 (12.9%) high-grade dysplasia and 14 (45.2%) low-grade dysplasia. The follow-up was from 2 to 12 years. Median survival for patients with IPMN and associated invasive carcinoma was 45.8 months and disease-free survival was 40.8 months. Conclusions: IPMN had higher prevalence in females, mostly symptomatic and high incidence of associated invasive carcinoma with branch type. The 5-year survival was good even with associated invasive carcinoma. (c) 2022 AEC. Published by Elsevier Espana, S.L.U. All rights reserved.
