Metformin is a well-tolerated drug widely prescribed for treatment of Type 2 diabetes mellitus. Preliminary studies have generated the hypothesis that metformin may have positive effects on both prevention and survival of colon cancer subjects. Clinical trials are ongoing to explore this possibility in breast cancer (NCT01101438). This investigation is the first study of Metformin in colorectal cancer (CRC) patients, and is designed to understand the mechanism of its anti-cancer actions, if any, and its interactions with biomarkers in colorectal cancer patients.\n\nBased upon epidemiological studies, it is hypothesized that there are independent actions of Metformin on the outcome of subjects with CRC.
