2 standard-of-care settings across 2 lines and 1 biomarker subgroup. Rows come from the cancer page's standard of care; the grid places each on its line and subgroup.
| Subgroup | Setting | Approach | Products and trials | Guideline | Evidence |
|---|---|---|---|---|---|
| All comers | Surveillance and prophylactic surgery in carriers | 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. | NICE NG151: colorectal cancer (published January 2020, last updated December 2021, last reviewed April 2026) | 94 |
| Subgroup | Setting | Approach | Products and trials | Guideline | Evidence |
|---|---|---|---|---|---|
| All comers | Cancer arising in polyposis | 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. | NICE NG151: colorectal cancer (published January 2020, last updated December 2021, last reviewed April 2026) | 82 |
Lines and subgroups are parsed from the setting text of each standard-of-care row and can misclassify an unusual phrasing; the row’s own setting is always shown. Guideline chips reflect the NCCN category and ESMO-MCBS grade recorded on the cancer page, checked on its stated date. Not medical advice.
