Overview of evidence (non-systematic literature review)

No systematic reviews were undertaken for this topic. Practice points were based on selected evidence and consensus. See Guidelines development process.

Health professionals performing follow-up

It has not been established whether outcomes differ by provider of follow-up care. For example it has not been established whether intensive (hospital-based) follow up is associated with a survival advantage over care provided by a general practitioner or clinical nurse consultant in colorectal cancer. Further studies are needed to determine whether community-based follow up can be adequately performed without decreasing patient survival, and to define the optimal balance between follow-up care provided by the general practitioner or clinical nurse consultant and the specialist.

Practice pointA recommendation on a subject that is outside the scope of the search strategy for the systematic review, based on expert opinion and formulated by a consensus process.Question mark transparent.png

Follow-up can be delivered as a combination of visits to the surgeon or associated gasteroenterologist, with ongoing care by the GPA medical professional who treats acute and chronic illnesses and provides preventive care and health education to a wide range of patients. and clinical nurse consultant.

Suggested follow-up schedule

After the routine review post discharge, patients should be reviewed at 3- to 6-monthly intervals for the first year (3 monthly in those patients who had poor prognostic factors such a positive margin, T4 disease and/or lymph node involvement, patients with stage III disease who decline chemotherapy), 6-monthly for the next two years and then yearly for a total of 5 years. There is no consensus on these intervals, as evidenced by the variability in follow-up protocols in the published literature, but there are organisations that would support a similar follow-up schedule.[1][2][3] This is a guide for the clinician and further trials will be necessary to establish optimal protocols. Less intensive follow-up may be considered for patients with early cancers (T1-2, N0) after discussion with the patient.

Clinical assessment includes history and physical examination. Regular carcinoembryonic antigen (CEACarcinoembryonic antigen. A protein that may be found in the blood of a person with colorectal cancer.) measurement (at each consultation) and annual computed tomography (CT) should be considered in follow-up protocols as they may provide useful in early detection of recurrence and the potential for surgery with curative intent. Positron emission tomographyA scan in which a person is injected with a small amount of radioactive glucose solution to find cancerous areas. (PET/CT) can be an effective alternative to standard CT after detection of a significant rise in CEACarcinoembryonic antigen. A protein that may be found in the blood of a person with colorectal cancer..[4][5][6]

ColonoscopyAn examination of the large bowel using a camera on a flexible tube, which is passed through the anus. should be performed 12 months after surgery to exclude missed lesions. If the patient did not have complete colonoscopy prior to surgery, then this should be performed at the latest 6 months after surgery. If the post-operative colonoscopy is normal then future surveillance should be according to the Clinical Practice Guidelines for Surveillance Colonoscopy.

Future studies should focus on the cost-effectiveness and efficiency of investigations employed.[7]Back to top
