Inquiry Details
References:
Solid Tumor Rules. Colon; December 2020 Update
Question:
Solid Tumor Rules (2018)/Histology--Colon: Should the mixed adenoneuroendocrine carcinoma (MANEC) row in Table 1 include the still often used (yet older) terms of adenocarcinoma and carcinoid, adenocarcinoid, etc. for clarity? See Discussion.
Discussion:
The Terms and Definitions Introduction discusses how these are older terms, but pathologists may still use them. In our region, pathologists do, in fact, still use these terms. Can these terms be added to Table 1? For registrars who do not reference the Introduction every time they code histology but go directly to Table 1, coding consistency would likely improve if such terms were added in the Table.
This question was prompted from preparing SEER*Educate coding exercises. We will use the answer as a reference in the rationales.
Answer:
The next update to the Solid Tumor rules will include adding the following four terms to Colon Table 1 as synonyms for Mixed adenoneuroendocrine carcinoma 8244
- Mixed adenoneuroendocrine carcinoma
