Question:

MP/H Rules/Histology--Colon: Per MP/H rule H3 for colon, code 8144/3 [Adenocarcinoma, intestinal type] should not be used with C180-C189 [colon]. However, page 58 of the ICD-O-3 SEER Site/Histology Validation list of February 9, 2001 lists code 8144/3 as a valid histology for large intestine. See Discussion.

Discussion:

None of the errata have this site/histo combination. It is causing problems with researchers because pathologists still use the term: Adenocarcinoma, intestinal type for tumors of the large bowel. Please clarify or print errata.

Answer:

For cases diagnosed 2007 or later:

This issue has been presented to the Edits work group. The preliminary response is that 8144/3 will be removed from the valid site/histology list for large intestine, small intestine, and rectum.

The edits based on the site/type list are used by many organizations. Any change to the site/type list is taken to the Edits work group.
