Colon cancer required more tests to detect one recurrence than rectal cancer because its recurrence rate was lower. Detecting one rectal cancer recurrence required 31 CEA tests, 8 CT scans, 4 colonoscopies, and 2 biopsies. Detecting one colon cancer recurrence required 148 CEA tests, 37 CT scans, 21 colonoscopies, and 6 biopsies. The study frames surveillance resource use as a balance between earlier detection, procedure burden, and surveillance harms.
