Study Summary

The purpose of this study is to find out whether METFORMIN decreases protein markers in colorectal tissue. This is a phase IIA study of the pharmacodynamics, safety and tolerability of Metformin in decreasing colorectal mucosa in patients with a history of colorectal adenomas in the past 3 years and a BMI \>= 30, with decimals rounded to the nearest whole integer. Metformin as a potential chemopreventive agent for inhibition of the relevant molecular pathways involved in human colorectal carcinogenesis.

Primary Outcome

Tissue S6Ser235 immunostaining was analyzed by the study pathologist using Histo Score (HScore) analysis at baseline and post- metformin (Week 12). The Hscore is determined by estimation of the percentage of cells positively stained with mild, moderate, or strong staining intensity. The final score is determined by weighted estimate, as follows: Hscore = (# cell stained with High intensity/total # cells)x3 + (# cells stained with median intensity/total # cells)x2 + (# cells stained with low inte

Interventions
