Colorectal neoplasia is the second most common cancer in the United States and other Western countries with about 140,000 newly diagnosed cases per year in the United States with a mortality rate of about 40%. The identification of a specific natural or synthetic compound with the ability to reverse or suppress the process of colon carcinogenesis would have profound implication in the development of colorectal adenomas and their subsequent transformation to colon cancer. Furthermore, the establishment of a correlative relationship between biomarkers of cell proliferation, differentiation, apoptosis and adenoma recurrence would provide pivotal data required to elucidate cell signaling mechanisms in future colon cancer chemoprevention trials.
