Re: CANCER-5
sudha2015 - 01-15-11 11:04 While extent of disease is certainly a risk factor for the development of colorectal carcinoma, duration of disease is recognized to be the most important risk factor. Eaden’s meta-analysis recently demonstrated the risk for colorectal carcinoma in ulcerative colitis patients is 2% at 10 years, 8% at 20 years, and 18% at 30 years of disease duration. It is now understood both ulcerative colitis and Crohn’s colonic disease share similar levels of colorectal carcinoma risk.
