  Purpose

Colon cancer is the second leading cause of cancer death in North America. These deaths are preventable with proper screening. Fecal occult blood testing, virtual colonoscopy, and standard (optical) colonoscopy are all options for colon cancer screening, but it is not known which is the best at preventing death from colon cancer. A large study comparing these three tests is desperately needed. In this pilot study, the investigators want to find out what percentage of patients will show up for their screening test once enrolled. This will provide crucial information for the successful execution of the larger study.

Primary Outcome Measures:
  • Proportion of enrolled patients who attend for their assigned screening test [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Proportion of non-responders to mailed invitations, who respond to telephone or mail reminders. [ Designated as safety issue: No ]
  • Proportion of patients requiring polypectomy after virtual colonoscopy who receive same or next day optical colonoscopy for polypectomy [ Designated as safety issue: No ]
  • Proportion of subjects who cross over to another arm of the study [ Time Frame: 6 months ] [ Designated as safety issue: No ]
  • Proportion of patients found to have an advanced adenoma [ Time Frame: 6 months ] [ Designated as safety issue: No ]
