Core Tip
Core tip: There has recently been a growing literature on the use of metformin as a potential preventive and therapeutic agent for various chronic liver diseases and hepatic malignancies. We therefore decided to review the efficacy of metformin across the spectrum of liver disease and malignancies. Based on our systematic review, there is insufficient evidence to recommend use of metformin in the adjunctive treatment of non-alcoholic fatty liver disease and hepatitis C. However, there is good evidence for a chemopreventive role against hepatocellular carcinoma among patients with diabetes and chronic liver disease, and metformin should be continued in patients even with cirrhosis to provide this benefit.
