Pancreatic Neuroendocrine Tumor by AJCC v8 Stage

**Semantic type:** Neoplastic Process

**Definition:** A term that refers to the staging of a pancreatic neuroendocrine tumor, following the American Joint Committee on Cancer (AJCC) v8 staging guidelines. This staging system applies to well-differentiated neuroendocrine tumors arising in the pancreas. Carcinomas of the pancreas, including high-grade (grade 3), poorly differentiated neuroendocrine carcinomas are not staged using this staging system. (from AJCC 8th Ed.)
