Description
Jenna Cross and colleagues measure what the guideline-recommended one-year surveillance colonoscopy actually finds after curative colorectal cancer surgery. Their 2026 retrospective study reviews 454 patients resected in Winnipeg between January 2007 and June 2020 whose first check fell within the accepted window. Findings were classed as cancer, advanced adenoma, simple adenoma, or normal.
The harvest was thin. Two patients, 0.44 percent of the group, harbored a new or missed cancer, and three more had advanced adenomas in the reported counts. Simple adenomas appeared in about one in five patients, while nearly eighty percent of examinations were entirely normal. Neither cancer case had been flagged by tumor marker blood tests or imaging beforehand. Missing records of the original examination quality limited judgment about whether lesions were new or overlooked. The authors present the low yield as real-world descriptive evidence.
