Hereditary Non-polyposis Colorectal Cancer (HNPCC)
Suggested Pre-Referral Evaluation and Management Guidelines
Referral is indicated if:
- patient has biopsy proven colon cancer
- patient has an endoscopically unresectable polyp
- patient is unable to undergo surveillance
Prophylactic removal of the colon in patients with HNPCC is not typically recommended. Surveillance, via colonoscopy, with removal of precancerous polyps every one to two years beginning between ages 20 and 25 years or ten years before the earliest age of diagnosis in the family, whichever is earlier, is recommended.
If colonoscopy and biopsy were performed outside of the UMHS system, reports should be faxed and pathology slides should be mailed for confirmatory review by our pathologists at or before the time of the clinic visit. Receiving these prior to the clinic visit is preferable
Suggested Additional Test/Management Prior to Specialty Visit
- Tattooing of the site if a lesion has been removed by colonoscopy
- If malignancy is detected, CT scan with IV and po contrast of the chest, abdomen, and pelvis within 6 weeks of the clinic visit
- Labs to include comprehensive metabolic panel, CBCP, PT, PTT, and CEA
Reports of any testing performed outside of the UMHS system and radiologic images on CD should be available for review at or before the time of the clinic visit. Receiving these prior to the clinic visit is preferable.
1-2 weeks if malignancy present or suspected. 4-8 weeks if no malignancy.
