#3425 Diagnostic role and prognostic value of tumor markers in high-grade GEP-NENs

Introduction: High-grade gastroenteropancreatic neuroendocrine neoplasms (GEP-NENs) can be divided into well differentiated neuroendocrine tumors G3 (NETs G3) and poorly differentiated neuroendocrine carcinomas (NECs). Diagnostic and prognosis value of tumor markers in this entity still remains unknown.

#1434 CA19-9 As a Prognostic Biomarker in Pancreatic Neuroendocrine Tumors

Introduction: Carbohydrate antigen19-9 (CA19-9) is generally not considered as a biomarker in pancreatic neuroendocrine tumors (pNETs) since most pNETs present with normal range of CA19-9.

#369 Carcinoid Tumor of Common Bile Duct (CBD) Misdiagnosed as Cholangiocarcinoma

Introduction: Carcinoid tumors of the bile duct are extremely rare. Unlike cholangiocarcinoma, they grow more slowly and generally occur in younger patients and in females. They have better prognosis and greater disease free survival.

#117 Synchronous appendiceal neuroendocrine carcinoma and mucinous cystadenocarcinoma: a case report

Introduction: Appendiceal tumors with histological features of both carcinoids and adenocarcinomas are very rare. Carcinomas of the appendix are usually mucinous adenocarcinomas with a tendency to produce peritoneal pseudomyxoma and without metastatic spread until late in the disease course. Carcinoid tumors of the appendix are a common incidental finding.
