Abstract

Background. Incidentally discovered nonfunctioning pancreatic endocrine tumors (NF-pNETs) increasingly are being detected, and their management is debated. Moreover, the prognostic importance of incidental diagnosis for locally advanced or metastatic NF-pNETs is unknown. The aim of this study is to analyze the outcomes of incidentally discovered/symptomatic NF-pNETs stratified by tumor stage. A preliminary experience with nonoperative treatment of incidental NF-pNETs is reported. Methods. Consecutive patients with symptomatic/incidental NF-PETs observed between 1990 and 2009 were analyzed, with different tumor stages considered. Nonoperative management of incidental NF-pNETs was evaluated. Results. Among 355 patients with NF-pNETs, the diagnosis was incidental in 124 (35%). Incidental NF-pNETs were associated more commonly with lower tumor stages compared with symptomatic tumors (P
