A Case Report of NET G1 of the Gallbladder Abstract #1692

Introduction: The SEER database has shown that gallbladder NET is 0.5% of all NET cases, and G1 cases are limited to 2% in the rare gallbladder NET cases.
Aim(s): Here we experienced a rare case of G1 NET in the gallbladder, and report the clinical features of our case.
Materials and methods: Case: The patient was 48 year-old man, incidentally pointed out a mass in the cystic duct. Dynamic CT scan showed a space-occupying lesion in the cystic duct. MRCP showed papillary lesion protruding into the cystic duct. Those scans showed no signs of invasive tumor, and the tumor was just localized within the cystic duct. FDG-PET showed no significant accumulation. Duct biopsy and bile cytology was negative for malignancy, but imaging analysis never excluded the malignant possibility.

#1428 Factors Affecting Recurrences of the Non-functioning Pancreatic NET After Resection
Introduction: In 2010, WHO classification has been modified. However, the usefulness of the criteria for surgeons has not been elucidated, because the criteria is defined by cell growth represented by Ki67 for overall survival and may not represent invasiveness of the tumor.

Introduction: There remains several unsolved issues to be settled about the management of pancreatic neuroendocrine tumors (PNETs) after resection. One of these problems are the follow up period after a complete resection of the tumor.

#1666 Prognosis and Incidence in Pancreatic and Gastrointestinal Neuroendocrine Neoplasms with Emphasis on “NET G3”: An Analysis of 198 Cases from Japan
Introduction: Prognostic impact of well differentiated pancreatic neuroendocrine neoplasms (PanNENs) with a Ki67 >20%, provisionally called NET G3, needs to be validated and compared to poorly differentiated neuroendocrine carcinomas (NECs). Moreover, the frequency of NET G3 among gastrointestinal NENs (GI-NENs) has so far not been studied.
