Here's are the NCCN, National Comprehensive Cancer Network Surveillance guidelines for Rectal Cancer:
- History and physical every 3-6 mo for 2 y, then every 6 mo for a total of 5 y
- CEA every 3-6 mo for 2 y, then every 6 mo for a total of 5 y for T2 or greater lesions
- Chest/abdominal/pelvic CT annually for up to 5 y for patients at high risk for recurrence
- Colonoscopy in 1 y except if no preoperative colonoscopy because of obstructing lesion, colonoscopy in 3-6 mo
- If advanced adenoma, repeat in 1 y
- If no advanced adenoma, repeat in 3 y, then every 5 y
- Consider proctoscopy every 6 mo x 5 y for patient status post LAR
- PET-CT scan is not routinely recommended
- See Principles of Survivorship (page 1540)
I would follow these at a minimum, special case may require more follow-up
