Pancreatic endocrine tumors

Gastroenterol Clin North Am. 2007 Jun;36(2):431-9, x-xi. doi: 10.1016/j.gtc.2007.03.002.

Abstract

Incidental, nonfunctional pancreatic endocrine tumors (PET) are observed with increasing frequency. Most are insulinomas. Endoscopic ultrasound with fine-needle aspiration plays a significant role in the localization and tissue diagnosis of PET. Establishing PET behavior as aggressive or indolent remains challenging especially preoperatively. Newer techniques including DNA and micro-RNA analysis may play a role in this arena. Small benign PET may be enucleated or removed laparoscopically. Surgery is the mainstay of treating advanced disease including those with metastases and Zollinger-Ellison syndrome. The management of multiple endocrine neoplasia type 1 continues to be a challenge, including treating symptoms, targeted resections, and close observation. Diagnosis, management, and prognostication of PET are under evolution and a number of changes in these fronts are anticipated.
