Recurrence Detection

Current surveillance detected most colon cancer recurrences but left about 17.5% undetected over five years. Current surveillance detected most rectal cancer recurrences but left about 14.5% undetected over five years. Distant recurrence made up most predicted recurrences in both colon and rectal cancer. Rectal cancer had more predicted recurrences per 10,000 patients than colon cancer. Current NCCN-guideline surveillance detects most colorectal cancer recurrences but misses a meaningful minority.
