Figure 1: Surveillance Strategy for Off-protocol WW patients.

Figure 1:

Shown is a surveillance strategy utilized in patients followed after cCR off-protocol. The surveillance includes endoscopy, digital rectal exam and MRI-rectum for the follow-up of patients after they achieve a cCR. In addition, regular CEA checks and axial CT imaging is completed. Suggested intervals are shown. An alternative regimen used by some includes 3 monthly intervals in year 1, extending to 4 monthly intervals in year 2 after cCR is declared for endoscopy, digital exam and MRI-rectum and then extending the intervals to every 6 months for years 3–5.
