Colonoscopic surveillance reduces mortality from colorectal cancer in ulcerative colitis.
BACKGROUND
To control the increased risk of colorectal carcinoma in patients with long-standing ulcerative colitis, surveillance colonoscopy is widely recommended.


METHODS
To assess the role of colonoscopic surveillance in affecting colorectal carcinoma-related mortality, an outcome analysis was performed.


RESULTS
Among the total of 41 patients who developed carcinoma associated with ulcerative colitis, 19 patients were under colonoscopic surveillance and 22 patients were not. Carcinoma was detected at a significantly earlier Dukes' stage in the surveillance group (P = 0.039). Four patients in the surveillance group died, compared with 11 patients in the no-surveillance group. The 5-year survival rate was 77.2% for the surveillance group and 36.3% for the no-surveillance group (P = 0.026).


CONCLUSIONS
These results suggest that colonoscopic surveillance reduces colorectal carcinoma-related mortality by allowing the detection of carcinoma at an earlier Dukes' stage.
