Overview
Secondary prevention of colorectal cancer, as opposed to primary prevention, indicates that a person has already had the disease and there are steps being taken to prevent cancer recurrence, usually as metachronous tumors. This involves annual surveillance with colonoscopy after surgical removal and possibly an adjunct after the initial operation. The timing for secondary prevention is critical to prevent recurrent advanced disease.
Colorectal Cancer Secondary Prevention
Familial Colorectal Cancer Syndromes
- Surgical resection followed by yearly colonoscopy for most polyposis syndromes[1]
- The criteria for surveillance and categorizing them as polyposis patients include the following:
- Chemoprevention has been used as an adjunct to colonoscopy in some FAP patients, such as the following:
- Cyclooxygenase (COX) inhibitors[1]
- Aspirin and other nonsteroidal antiinflammatory drugs (NSAIDs)[2]
Sporadic Colorectal Cancer Syndromes
- An individual may develop sporadic colorectal cancer for the following reasons[1]:
- The patient has an unrecognized familial syndrome
- The residual tumor may be present after resection
- The patient has strong risk factors
- The patient has genetic risk factors that do not fit into a familial syndrome
- After the diagnosis, a colonoscopy should be performed to rule out synchronous tumors and polyps along with a primary tumor resection[1]
The table below displays the guidelines for colonoscopy surveillance after the primary tumor resection[3].
| Colonoscopy Findings | Recommeded Surveillance Interval (years) |
| No polyps | 10 |
| Small (< 10 mm) hyperplastic polyps in rectum or sigmoid | 10 |
| 1-2 small (< 10 mm) tubular adenomas | 5-10 |
| 3-10 tubular adenomas | 3 |
| >10 adenomas | < 3 |
| One or more tubular adenomas ≥ 10 mm | 3 |
| One or more villous adenomas | 3 |
| Adenoma with high grade dysplasia (HGD) | 3 |
| Sessile serrated polyp(s) < 10 mm with no dysplasia | 5 |
| Sessile serrated polyp(s) ≥ 10 mm | 3 |
| Sessile serrated polyp with dysplasia | 3 |
| Traditional serrated adenoma | 3 |
| Serrated polyposis syndrome (one of the following criteria according to WHO: (1) at least 5 serrated polyps proximal to sigmoid, with 2 or more ≥ 10 mm (2) any serrated polyps proximal to sigmoid with family history of serrated polyposis syndrome (3) > 20 serrated polyps of any size throughout the colon) | 1 |
