Question:
Reportability--Colon: Is a polypectomy that is suspicious for invasive adenocarcinoma followed by a partial colectomy with no residual neoplasm reportable? See Discussion.
Discussion:
08/28/2009 Cecum biopsy showed an adenomatous polyp with focal areas suspicious for invasive adenocarcinoma.
SINQ 20071060 states a suspicious biopsy that is disproven by a subsequent surgical procedure is not reportable. That does not seem to apply in this case because the patient had a suspicious finding on a surgical procedure (polypectomy), followed by a second surgical procedure that was negative. Is it possible that the polypectomy removed the entire tumor and the suspicious diagnosis should be reported?
Answer:
This case is reportable.
It is possible that the polypectomy removed the entire tumor. Invasive carcinoma in a polyp does not mean that is has invaded the stalk of the polyp. If the stalk is not invaded, all of the cancer may have been removed by a polypectomy.
