Question:
Reportability--Pancreas: Are neuroendocrine "tumors" reportable and are they synonymous with neuroendocrine "carcinoma"? See Discussion.
Discussion:
Example: Pancreatic mass that probably represents a neuroendocrine tumor is staged as cT2N0M0.
Answer:
According to the World Health Organization (WHO) pancreatic neuroendocrine tumors (NET) are malignant. They are reportable.
For pancreas primaries, code NET, G1 (well differentiated) to 8240/3; NET G2 (moderately differentiated) to 8249/3; and nonfunctional NET, GI or G2 to 8150/3.
The histology code for neuroendocrine carcinoma (NEC) is 8246/3, large cell NEC is 8013/3 and small cell NEC is 8041/3.
