Every dated change on the records linked to Familial adenomatous polyposis-associated colorectal cancer, newest first: approvals and regulatory steps on its medicines, trials that reported, guideline versions, milestones, and when this page itself was checked. Dates come from the records; none is inferred. Orientation, not medical advice.
Staged and treated as colorectal adenocarcinoma of the same stage, with the extent of resection decided by the field of polyps rather than by the single tumour; the parent record carries the systemic therapy rows.
Colonoscopy from about age 10 to 12 at one to two-yearly intervals; prophylactic colectomy before cancer develops, with the type and timing decided case by case; lifelong endoscopic surveillance of the retained rectum or ileal pouch afterwards; upper gastrointestinal endoscopy with ampullary visualisation at intervals set by duodenal and gastric findings.
