Are they the same as neuroendocrine carcinoma? See discussion. Discussion Example: Pancreatic mass that PROB represents a neuroendocrine tumor. Staged as cT2N0M0. Answer The World Health Organization (WHO) designates pancreatic neuroendocrine tumors (NET) as malignant. Therefore, they are reportable. For pancreas primaries, code NET, G1 (well differentiated) as 8240/3; NET G2 (moderately differentiated) as 8249/3; and nonfunctional NET, GI or G2 as 8150/3.
Neuroendocrine carcinoma (NEC) is coded 8246/3, or 8013/3 for large cell NEC, or 8041/3 for small cell NEC.
