Question:
First course treatment/Date 1st surgical procedure--Colon: Should the date of a polypectomy be recorded in the Date of First Surgical Procedure field when the entire tumor is not removed by polypectomy? See Discussion.
Discussion:
The patient underwent a polypectomy. The endoscopy report noted the "single piece polypectomy" only partially removed the polyp/mass as the remainder of the mass was more fixed to the wall. The margins were not noted on the pathology report, but were presumably positive given the endoscopy report and the subsequent low anterior resection (LAR) that proved macroscopic residual tumor. Should the date of the polypectomy be recorded in Date of First Surgical Procedure field? Or would the date of the subsequent LAR be recorded since macroscopic residual tumor was present following polypectomy?
Answer:
Record the date of the polypectomy as the date of first surgical procedure. Polypectomies are surgery for the purposes of cancer registry data collection regardless of whether or not there is residual tumor after the polypectomy.
