Discrepancy Between Radiologic and Pathologic Measurements in Pancreatic Neuroendocrine Tumors: A Retrospective Study on 199 Patients

#1165

Introduction: Preoperative radiologic size of pancreatic neuroendocrine tumors (PNET) is a crucial parameter in selection of appropriate treatment especially for incidentally discovered lesions (<20 mm). The current guideline bases the therapeutic recommendations on the pathologic size.

Aim(s): Evaluate the discrepancy between radiologic size (RS) and pathologic size (PS) of PNET

Materials and methods: Patients resected for PNET between January 2004 and November 2014 at our Institution were retrieved from a electronic database and analyzed retrospectively. We excluded functioning and cystic PNET and R2 resections. RS is defined as the mean of the largest diameters measured on CT, EUS and MRI, and PS as the largest diameter of the tumor on the histological report of the surgical specimen
