Trial Summary

What is the purpose of this trial?

RATIONALE: Screening tests, such as colonoscopy and fecal occult blood test, may help doctors find tumor cells early and plan better treatment for colorectal cancer.

Treatment Details

Interventions

• annual screening
• fecal occult blood test
• screening colonoscopy
• standard follow-up care

Trial Overview This phase III trial is comparing two types of colorectal cancer screening methods: an annual fecal occult blood test that checks for hidden blood in stool, versus a screening colonoscopy which involves examining the inner lining of the large intestine for abnormalities.

Participant Groups

Group I: Study II- Arm I Experimental Treatment 1 Intervention

Participants undergo baseline screening colonoscopy. Participants are given individualized recommendations for further surveillance based on the results of the colonoscopy.

Group II: Study I- Arm II Experimental Treatment 2 Interventions

Participants receive standard care

Group III: Study I- Arm I Experimental Treatment 1 Intervention

Participants undergo baseline screening colonoscopy

Group IV: Study II- Arm II Active Control 2 Interventions

Participants undergo a baseline fecal occult blood test (FOBT). Participants are given individualized recommendations for further surveillance based on the results of the FOBT. Participants with negative baseline FOBT undergo FOBT annually for up to 4 years in the absence of a positive FOBT.
