Abstract

Intraductal papillary mucinous neoplasms (IPMNs) have malignant potential and can progress from low- to high-grade dysplasia to invasive adenocarcinoma. The management of patients with IPMNs is dependent on their risk of malignant progression, with surgical resection recommended for patients with branch-duct IPMN (BD-IPMN) who develop high-risk features. There is increasing evidence that liver transplant (LT) patients are at increased risk of extrahepatic malignancy. However, there are few data regarding the risk of progression of BD-IPMNs in LT recipients. The aim of this study was to determine whether LT recipients with BD-IPMNs are at higher risk of developing high-risk features than patients with BD-IPMNs who did not receive a transplant. Consecutive patients who underwent an LT with BD-IPMNs were included. Patients with BD-IPMNs with no history of immunosuppression were used as controls. Progression of the BD-IPMNs was defined as development of a high-risk feature (jaundice, dilated main pancreatic duct, mural nodule, cytology suspicious or diagnostic for malignancy, cyst diameter ≥3 cm). Twenty-three LT patients with BD-IPMN were compared with 274 control patients. The median length of follow-up was 53.7 and 24.0 months in LT and control groups, respectively. Four (17.4%) LT patients and 45 (16.4%) controls developed high-risk features (P = 0.99). In multivariate analysis, progression of BD-IPMNs was associated with age at diagnosis but not with LT. There was no statistically significant difference in the risk of developing high-risk features between the LT and the control groups.
