Screening guidelines tool Disclaimer: This material is intended as a general summary of screening and management recommendations; it is not intended to be comprehensive. Colorectal cancer (CRC) screening guidelines are updated at regular intervals and may change over time. Providers should view the most up-to-date version of the relevant NCCN Colorectal Screening guidelines at nccn.org/professionals/physician_gls/f_guidelines.asp, and the American College of Gastroenterology Guidelines for Colorectal Cancer Screening. Screening recommendations for individual patients vary according to their level of risk, with patients at higher risk requiring more intensive and more frequent interventions to reduce morbidity and mortality. Risk is not static and may change over time based on changes in both personal and family medical history. Therefore, it is important to update patient information regularly and to store this information in a format that is easy to interpret and modify. Screening guidelines for individuals at average (population) risk Summary of CRC screening recommendations guide Average risk Age 50; Age 45 for African American men No history of adenoma or hamartoma No history of inflammatory bowel disease Negative family history Most patients fall into this category; they have little or no family history and no personal risk factors. These patients can be advised that specific lifestyle changes may modify the risk for colon and other cancers. Colonoscopy every 10 years; or Flexible sigmoidoscopy every 5 years; or Double contrast barium enema every 5 years; or Computed tomographic colonography every 5 years; or Fecal immunochemical test (FIT) Colonoscopy is the most effective and most invasive. All other screening tests may result in referral for colonoscopy if the test is abnormal or if a polyp is found that needs removal.

Screening guidelines for individuals at increased risk This category includes those who have one first- or two second-degree relatives* with colon cancer, and those with personal risk factors such as inflammatory bowel disease or a history of polyps. These patients are at higher-than-average risk but do not meet the criteria for a hereditary colon cancer syndrome. Regular updates of family history are important because the diagnosis of polyps, CRC or a Lynch-related cancer in one or more relatives may change a patient s risk category. Patients can be counseled that lifestyle changes may help modify their risk. Summary of patient history and CRC screening recommendations Increased risk NOTE: Evaluate for possible hereditary cancer syndrome 1 2 small tubular adenoma(s); <1cm Colonoscopy every 5 10 years after initial polypectomy 3 10 adenomas or 1 adenoma > 1cm, villous features or high-grade dysplasia Colonoscopy 3 years after initial polypectomy, if normal or if 1 2 small tubular adenomas, then every 5 years Personal history of CRC, after curative surgery Colonoscopy in one year or earlier in absence of complete preoperative colonoscopy; repeat every 1 3 years depending on results; periodic limited endoscopic evaluation of rectal anastomosis to identify local recurrence; new primary cancer should prompt update of family history and consideration of possible hereditary cancer syndrome >10 adenomas on a single exam Individual management including colonoscopy <3 years after initial polypectomy; evaluate for FAP/AFAP CRC or adenomatous polyps in any FDR* <60, or two or more in FDRs at any age, or multiple cases of Lynch/HNPCC** related cancers Colonoscopy every 3 5 years starting at age 40 or 10 years before youngest case in immediate family CRC or adenomatous polyps in any FDR* 60 or two SDRs* with CRC Colonoscopy every 5 years beginning at age 50 Inflammatory bowel disease (Chronic ulcerative colitis, Crohn s colitis) Colonoscopy with biopsies for dysplasia every 1 2 years starting 8 10 years after onset of symptoms Additional sampling of strictures and masses Endoscopic polypectomy with appropriate biopsies of surrounding mucosa for assessment of dysplasia If dysplasia or intraepithelial neoplasia, prophylactic protocolectomy with ileoanal pouch preferred *A first-degree relative (FDR) is a parent, sibling or child. A second-degree relative (SDR) is a grandparent, grandchild, uncle, aunt, nephew, niece, half-sibling. **HNPCC related cancers [CRC, endometrial, ovarian, duodenal/small bowel, gastric, ureteral/renal pelvis, hepatobillary/pancreas, brain (particularly glioblastoma), sebaceous adenoma/or sebaceous carcinoma]. Note that the American College of Gastroenterology considers CRC or adenomatous polyps in any FDR 60 as average risk, with colonoscopy every 10 years beginning at age 50.

Screening guidelines for individuals at high risk This category includes patients who have been diagnosed with a hereditary colon cancer syndrome such as Lynch/HNPCC or FAP/AFAP, or have a highly suggestive family or personal history. Because of the high risk for colon and other cancers, these individuals require more intensive and frequent screening. Prophylactic surgery for risk reduction and participation in clinical trials are often options for these patients. They benefit from a referral to a cancer genetics specialist to discuss the implications of their diagnosis in more detail.
