Can the recommendations be summarized into a chart for reference?
Here are the recommendations from the Society of Gastrointestinal and Endoscopic Surgeons and the American Society of Gastrointestinal Endoscopy.
SUMMARY OF RECOMMENDATIONS FOR SCREENING AND SURVEILLANCE COLONOSCOPY IN INDIVIDUALS AT INCREASED RISK FOR COLORECTAL CANCER
I. Patients with significant personal history
|
PERSONAL HISTORY |
SURVEILLANCE RECOMMENDATION |
|
Prior colorectal cancer |
Colonoscopy at 3 years after curative resection and clearance of the remainder of the colon at or around the time of resection, then at 3-5 year intervals to detect metachronous neoplasia. |
|
Prior colonic adenomas |
After adequate clearance, surveillance colonoscopy at 3-5 year intervals. |
|
Ulcerative pancolitis (colitis affecting the entire colon) of 8 years duration
Left sided colitis >15 years duration |
Surveillance colonoscopy every 1-3 years with systematic biopsies to detect dysplasia. |
II. Patients with significant family history
|
FAMILY HISTORY |
SCREENING RECOMMENDATION |
|
Familial adenomatous polyposis
FAP with positive genetic test in proband (type of genetic test)
FAP with negative genetic test in proband |
Offer genetic testing with genetic counseling: if positive, annual sigmoidoscopy beginning at age 10-12 years with colonectomy (sp?) when polyps develop. If no polyps annual sigmoidoscopy to age 40 then every 3-5 years thereafter.
Sigmoidoscopy in all potentially affected relatives performed as above. |
|
HNPCC
Hereditary non-polyposis colon cancer |
Colonoscopy every 2 years beginning at age 25, or 5 years younger than the earliest age of diagnosis of colorectal cancer, whichever is earlier. Annual screening after age 40. |
|
First-degree relatives with sporadic colorectal cancer or adenomas before the age of 60 or multiple first degree relatives with colorectal cancer or adenomas. |
Colonoscopy every 3-5 years beginning at age 10 years earlier than the youngest affected relative. |
