Outcome Measures

Primary Outcomes (1)

  • To determine colonoscopy polyp and cancer detection rate

    The hypothesis for this study was that colonoscopy surveillance of a high-risk cohort of patients with rectal bleeding would demonstrate that 10-20% of these patients have pre-malignant colorectal polyps(adenomas) or cancers.

    2 years

Secondary Outcomes (1)

  • To detect colorectal cancer early using symptoms based assessment

    2 years
