Pancreatic cystic endocrine tumors: a different morphological entity associated with a less aggressive behavior.

#32

Introduction: Cystic pancreatic endocrine tumors (CPETs) are rare lesions and their biological features have been scarcely investigated.

Aim(s): To compare clinical and pathological features of CPETs with solid PETs (SPETs) in a single institutional experience of non-functioning sporadic pancreatic endocrine tumors (NF-PETs).

Materials and methods: All patients with a pathologically confirmed diagnosis of sporadic NF-PETs who underwent curative resection at our institution between 1988 and 2008 were included. A comparison of demographic, clinical and pathological characteristics between CPETs and SPETs was made. Univariate and multivariable analyses were performed to identify preoperative predictors of existing non-functioning pancreatic endocrine carcinoma (NF-PEC).
