Question:
Reportability/Histology--Colon: Is tubular adenoma with high grade dysplasia and focal invasion from a pathology report of a colon biopsy reportable?; if so, what is the histology code?
Discussion:
Answer:
Tubular adenoma with high grade dysplasia and focal invasion is reportable. Assign the histology code and behavior as 8210/3 (Adenocarcinoma in tubular adenoma).
NAACCR Guidelines for ICD-O-3 Implementation discuss the term high grade dysplasia (without invasion). High grade dysplasia and related terms are under review and study for consideration as a reportable neoplasm. Registries should check with their state reporting legislation to see if included in the reporting requirements.
