Colorectal cancer.

I'd like to summarize by letting you know that the field is very aggressively expanding in the areas of molecular biology. There isn't much new in terms of chemotherapy or surgery other than the advances I've just spoken to you about, but I think screening tests will allow us to decrease the mortality from colon cancer. We have been able to document that sigmoidoscopy can decrease the risk of colon cancer by about 45 percent in the United States; the mortality rates are continuing to decrease. I'd be happy to answer some questions that I might have stimulated. Thank you.
