Rating Scheme for the Strength of the Recommendations
The Clinical Practice Guidelines (the "Guidelines") have been developed by the Guidelines and Protocols Advisory Committee on behalf of the Medical Services Commission. The Guidelines are intended to give an understanding of a clinical problem, and outline one or more preferred approaches to the investigation and management of the problem. The Guidelines are not intended as a substitute for the advice or professional judgment of a health care professional, nor are they intended to be the only approach to the management of clinical problem.
Hand-searches of Published Literature (Primary Sources)
Searches of Electronic Databases
Systematic Literature Review
Evidence was obtained through a systematic review of peer-reviewed literature (up to May 2012) using the databases MEDLINE, PubMed, EBSCO, Ovid, and the Cochrane Collaboration's Database for Systematic Reviews. The searches also included: Canadian Agency for Drugs and Technologies in Health (CADTH), Cumulative Index to Nursing and Allied Health Literature (CINAHL), Therapeutics Initiative, Cochrane reviews, BMJ Clinical Evidence, e-Therapeutics (Compendium of Pharmaceuticals and Specialties), Agency for Healthcare Research and Quality (AHRQ), and US Food and Drug Administration (FDA). Clinical practice guidelines from other jurisdictions for colorectal cancer follow-up and surveillance were also reviewed (up to January 2013).
Search terms included: colon tumor/ colon cancer/ colon adenocarcinoma/ colon carcinoma/ colorectal carcinoma/ colorectal tumor/ sigmoid carcinoma/ rectum cancer/ rectum tumor/ rectum carcinoma/ rectum adenoma/ colorectal cancer/ randomization/ randomized controlled trial/ double blind procedure/ single blind procedure/ metastasis/ cancer recurrence/ tumor recurrence/ recurrent disease/ (recur$ or metastas:).ti,ab. / longitudinal study/ (follow-up or follow up).ti,ab. / follow up/ prospective study/ treatment outcome/ cancer survival/ quality of life/ prognosis/ mortality/ morbidity/ exp survival/
Exclusion criteria were study limitations, inconsistency of results, indirectness of evidence, reporting bias, duplicate evidence and incomparable populations.
The evidence review process used in the development of these guidelines is conducted with reference to the Oxford Centre for Evidence-Based Medicine (CEBM) levels of evidence (March 2009) (www.cebm.net).
The working group reviewed available systematic reviews and based recommendations upon them. In cases where systematic reviews are not available, recommendations are based on primary evidence searches including individual randomized controlled trials.
The working group reviewed the evidence available at the time of writing (January 2011–May 2012) and, through consensus, distilled this evidence into a usable document for family physicians. The primary evidence used is listed in the reference section of the guideline.
A formal cost analysis was not performed and published cost analyses were not reviewed.

To provide follow-up recommendations for patients after curative resection of colorectal cancer (CRC) or polypectomy
Patients who have undergone curative resection of colorectal cancer (CRC) or polypectomy
Note: These recommendations do not apply to patients with familial adenomatous polyposis (FAP), hereditary non-polyposis colon cancer (HNPCC) or inflammatory bowel disease. Recommendations for these patients and for the detection of colorectal neoplasms in asymptomatic patients are found in the National Guideline Clearinghouse (NGC) summary of the Medical Services Commission, British Columbia guideline Colorectal screening for cancer prevention in asymptomatic patients.
- Post-polypectomy surveillance
- Fecal occult blood test (FOBT) for hyperplastic polyps
- Follow-up colonoscopy for adenomas, with surveillance intervals based on risk and other clinical factors
- Post-cancer resection follow-up
- Follow-up visits with family physician (history, physical examination, routine laboratory investigations) (not currently recommended)
- Carcinoembryonic antigen (CEA) testing
- Liver imaging by ultrasound or computed tomography (CT) scan
- Chest x-ray
- Colonoscopy with complete cancer and polyp clearing
- FOBT (not recommended in this population)
- Continued surveillance every 5 years
Note: Aspirin and other nonsteroidal anti-inflammatory drugs (NSAIDs) and FOBT are not recommended for post-cancer resection follow-up.
- Risk of colorectal cancer (CRC) development and mortality
- CRC recurrence rate
- Sensitivity and specificity of diagnostic studies
- Effectiveness of surveillance testing
The majority of colorectal cancers (CRCs) arise from adenomas, the 'adenoma–carcinoma sequence'. Two major types of polyps are found in the colon and rectum: adenomas and hyperplastic polyps. Hyperplastic polyps are considered to have no malignant potential.
Table: Post-Colorectal Polypectomy Surveillance Recommendations (Brooks et al., 2008)
|Risk Group||Surveillance Recommendations|
|Patients with hyperplastic polyps||Follow-up as average risk.* See the National Guideline Clearinghouse summary of the Medical Services Commission, British Columbia guideline Colorectal screening for cancer prevention in asymptomatic patients.|
|Patients with 1 or 2 small (<1 cm) tubular adenomas with only low-grade dysplasia||Follow-up colonoscopy in 5 to 10 years. Timing within this interval should be based on other clinical factors (e.g., previous colonoscopy findings, family history, patient preferences, judgment of the physician).|
|Patients with 1 or more sessile serrated polyps <1 cm with no dysplasia||Follow-up colonoscopy in 5 years.|
|Patients with 3 to 10 tubular adenomas or any advanced adenomas (tubular adenomas ≥1 cm, villous adenomas, adenoma with high-grade dysplasia (HGD), sessile serrated polyps ≥1 cm, sessile serrated polyps with dysplasia, or traditional serrated adenoma)||Follow-up colonoscopy in 3 years provided that adenomas are completely removed. If the follow-up colonoscopy is normal or shows only 1 or 2 small (<1 cm) tubular adenomas with low-grade dysplasia, the interval for the subsequent examination should be 5 years.|
|Patients with sessile adenomas where complete removal is uncertain||Follow-up colonoscopy within 6 months to verify complete removal. Once complete removal has been established, subsequent surveillance should be as for advanced adenomas.|
|Patients suspected of having a hereditary colorectal cancer syndrome||When the family history indicates hereditary non-polyposis colon cancer (HNPCC) and familial adenomatous polyposis (FAP), colonoscopy every 1 to 2 years.**|
*Fecal occult blood test (FOBT) is an appropriate follow-up modality for this group. FOBT should not be used until 10 years after the last colonoscopy for the hyperplastic polyp patient. All other risk groups above should not be followed with FOBT.
**Individuals with HNPCC or FAP should be referred to the Hereditary Cancer Program at the BC Cancer Agency for assessment, counseling and if appropriate, genetic testing.
The goal of follow-up after resection is to identify recurrent disease or metastases and to detect subsequent adenomas. These recommendations are generally expert consensus-based. Patients with significant co-morbidities, very advanced age or limited 5 year life expectancy are not routinely offered surveillance.
Follow-up Visits with Family Physician
Focused history and physical examination are recommended every 3 to 6 months for 2 years, and then every 6 months for a total of 5 years (Desch et al, 2005; National Comprehensive Cancer Network [NCCN], 2012). It is recommended that each follow-up visit include:
- History to elicit gastrointestinal and constitutional symptoms, including nutritional status.
- Physical examination with particular attention to the abdomen, liver and rectal evaluation (or perineal inspection and palpation in those patients who have had an abdominal perineal resection).
- Routine laboratory investigations, such as liver chemistry, in the absence of symptoms are not useful.
Controversies in Care
Aspirin (and other nonsteroidal anti-inflammatory drugs [NSAIDS]) has been shown to reduce the incidence of subsequent colorectal adenomas and cancer, but because of potential adverse effects it is currently not recommended (Din et al., 2010).
A carcinoembryonic antigen (CEA) test is recommended at diagnosis of CRC and repeated to monitor rising levels of CEA (at least doubling) which can indicate hepatic or pulmonary metastases. Eligible patients for surveillance with CEA are those with stage II or III tumors (i.e., tumour through the bowel wall or metastatic to locoregional lymph nodes). These patients are offered CEA every 3 months for the first 3 years and every 6 months during years 4 and 5. No CEA is required beyond 5 years.
Imaging and X-Rays
Liver imaging, by ultrasound or computed tomography (CT) scan (CT preferable) (Kinkel et al., 2002; Miles & Burkill, 2007), is recommended every 6 months for the first 3 years, then once per year for 2 more years (Figueredo et al., 2003). For those with advanced stage cancers or undergoing chemotherapy, follow the recommendations of the oncologist (Desch et al., 2005; Pfister, Benson, & Somerfield, 2004). Routine CT scanning is not recommended beyond 5 years.
There is little evidence to show a survival benefit for routine chest x-ray for post CRC resection patients (Gan, Wilson, & Hollington, 2007). A chest CT scan is recommended for every 12 months for the first 3 years in cases of advanced cancer or rectal cancer (Desch et al., 2005; NCCN, 2012).
Patients with CRC should undergo a complete cancer and polyp clearing colonoscopy prior to or within 12 months of surgical resection of the colorectal tumour. A colonoscopy should follow at one year after resection or clearing colonoscopy (Brooks et al., 2008; NCCN, 2012). If the one year colonoscopy is normal, the next colonoscopy should be performed in 3 years; if those results are normal, the next colonoscopy should be performed in 5 years (Brooks et al., 2008; NCCN, 2012) to look for another primary colorectal malignancy or adenomatous polyps. After the one year colonoscopy, the intervals between subsequent colonoscopies may be shortened if there is evidence of hereditary non-polyposis colon cancer (HNPCC) or if adenoma findings warrant earlier colonoscopy.
Performance of fecal occult blood test (FOBT) is unnecessary in patients undergoing colonoscopic surveillance (Winawer et al., 2006).
Surveillance after 5 Years
Continued surveillance is recommended with a colonoscopy conducted every 5 years. There is no place for FOBT in this population.
