| Population | Recommendation | Grade |
| Adults aged 50 to 75 years | The USPSTF recommends screening for colorectal cancer in all adults aged 50 to 75 years. | A |
| Adults aged 45 to 49 years | The USPSTF recommends screening for colorectal cancer in adults aged 45 to 49 years. | B |
| Adults aged 76 to 85 years | The USPSTF recommends that clinicians selectively offer screening for colorectal cancer in adults aged 76 to 85 years. Evidence indicates that the net benefit of screening all persons in this age group is small. In determining whether this service is appropriate in individual cases, patients and clinicians should consider the patient's overall health, prior screening history, and preferences. | C |
| Rationale | Adults aged 45-49 y | Adults aged 50-75 y | Adults 76 y or older |
| Detection | • The USPSTF found adequate evidence that screening for colorectal cancer with several different methods can accurately detect early-stage colorectal cancer and adenomatous polyps • Several studies on screening test accuracy include persons younger than 50 y, although few report screening test accuracy specifically for that age group. Those studies that do report accuracy report similar sensitivity and specificity | The USPSTF found convincing evidence that screening for colorectal cancer with several different methods can accurately detect early-stage colorectal cancer and adenomatous polyps | The USPSTF found convincing evidence that screening for colorectal cancer with several different methods can accurately detect early-stage colorectal cancer and adenomatous polyps |
| Benefits of early detection and intervention and treatment | • The USPSTF found adequate evidence that screening for colorectal cancer with stool tests, colonoscopy, CT colonography, or flexible sigmoidoscopy in adults aged 45 to 49 y provides a moderate benefit in terms of reducing colorectal cancer mortality and increasing life-years gained • Although no studies report on the benefits of screening specifically in adults younger than 50 y, some studies reporting an association of fewer colorectal cancer deaths with screening colonoscopy and reduced colorectal cancer mortality with screening gFOBT included patients younger than 50 y • Modeling analyses suggest more life-years are gained and fewer colorectal cancer deaths occur when screening begins at age 45 vs 50 y | The USPSTF found convincing evidence that screening for colorectal cancer with stool tests, colonoscopy, CT colonography, or flexible sigmoidoscopy in adults aged 50 to 75 y provides a substantial benefit in reducing colorectal cancer mortality and increasing life-years gained | The USPSTF found adequate evidence that routine screening for colorectal cancer with stool tests, colonoscopy, CT colonography, or flexible sigmoidoscopy in adults aged 76 to 85 y provides a small to moderate benefit in reducing colorectal cancer mortality and increasing life-years gained |
| Harms of early detection and intervention and treatment | • The USPSTF found adequate evidence that the harms of screening for colorectal cancer in adults aged 45 to 49 y are small. The majority of harms result from the use of colonoscopy (such as bleeding and perforation), either as the screening test or as follow-up for positive findings detected by other screening tests • Although fewer studies include persons younger than 50 y, overall findings suggest risk for bleeding and perforation with colonoscopy and risk for extracolonic findings with CT colonography may be lower at younger ages | The USPSTF found adequate evidence that the harms of screening for colorectal cancer in adults aged 50 to 75 y are small. The majority of harms result from the use of colonoscopy (such as bleeding and perforation), either as the screening test or as follow-up for positive findings detected by other screening tests | • The USPSTF found adequate evidence that the harms of screening for colorectal cancer in adults 76 y and older are small to moderate. The majority of harms result from the use of colonoscopy (such as bleeding and perforation), either as the screening test or as follow-up for positive findings detected by other screening tests • The rate of serious adverse events from colonoscopy and the detection of extracolonic findings on CT colonography from colorectal cancer screening increase with age |
| USPSTF assessment | The USPSTF concludes with moderate certainty that there is a moderate net benefit of starting screening for colorectal cancer in adults aged 45 to 49 y | The USPSTF concludes with high certainty that there is a substantial net benefit of screening for colorectal cancer in adults aged 50 to 75 y | The USPSTF concludes with moderate certainty that there is a small net benefit of screening for colorectal cancer in adults aged 76 to 85 y who have been previously screened |
| TYPE | INTERVAL | LIMITATIONS | PATIENT BURDEN | COST AND REIMBURSEMENT |
| FIT | Annual | • High nonadherence to annual testing (especially in absence of reminder systems) • Less effective for advanced adenoma detection • Few available tests have published peer-reviewed performance data | • Is done at home • Many brands require only a single sample • No diet or medication restrictions | • Inexpensive compared with structural examinations and mt-sDNA • Follow-up colonoscopy for positive test may be subject to out-of-pocket costs |
| gFOBT | Annual | • High nonadherence to annual testing (especially in absence of reminder system) • Less effective for advanced adenoma detection • Difficulty in ascertaining test performance among the many FDA-cleared tests | • Is done at home • Requires multiple samples • Requires dietary and medication restriction • Higher false-positive rate than FIT leads to more colonoscopies | • Inexpensive compared with structural examinations and mt-sDNA • Follow-up colonoscopy for positive test may be subject to out-of-pocket costs |
| sDNA | 1-3 years | • This is a new test, with limited data on screening outcomes, and its performance needs to be monitored over time • There may be uncertainty in management of positive results followed by a negative colonoscopy | • Can be done at home • Does not require bowel preparation, anesthesia or sedation, or transportation to and from the screening examination (test is performed at home) | • More expensive than other stool-based tests • Follow-up colonoscopy for positive test may be subject to out-of-pocket costs |
| Colonoscopy | 10 years | • Risk of bowel perforation/bleeding and cardiopulmonary complications of anesthesia • Performance is dependent upon adequacy of bowel preparation, the cecal intubation rate, withdrawal time, and adenoma detection rate • Limited collection of quality data in many settings • Level of adherence to 10-y interval is unknown • Lower sensitivity for neoplasia in the proximal than the distal colon | • Requires full bowel cleansing • Requires time off work and a chaperone (if sedation is used) | • Most expensive test, but currently reimbursable for those with insurance coverage • Polypectomy and anesthesia may be subject to out-of-pocket costs |
| CT Colonography | 5 years | • Incidental extracolonic findings may require workup, with unclear benefit-burden balance • Exposure to low-dose radiation | • Requires full bowel cleansing • Colonoscopy required if test positive. If same day colonoscopy is not possible, a second bowel cleansing will be required before the follow-up colonoscopy. | • Relatively expensive and may not be covered by insurance (not covered by Medicare at this time) • Follow-up colonoscopy for positive test may be subject to out-of-pocket costs |
| Flexible Sigmoidoscopy | 5-10 years | • Does not examine the proximal colon • Concerns about lack of quality standards, limited availability, failure to achieve a complete examination | • Pain and discomfort • Requires enema prior to procedure • Abnormal findings require second endoscopic procedure (colonoscopy) | • Follow-up colonoscopy for positive test may be subject to out-of-pocket costs |
