Abstract

Background: There is discrepancy of results among various individual and me-ta-analytical studies about the effect of metformin on cancer risk and patients' survival. Therefore, we have conducted a comprehensive, updated meta-analysis to evaluate the preventive and therapeutic effects of metformin for cancer patients, as well as the inci-dence of adverse reactions, among metformin users.

Methods: A total of 18 studies (10 cohort studies and 8 randomized controlled trials) in-volving 1,300,820 participants from Europe, North America, and Asia were included in this meta-analysis.

Results: No significant association was found between metformin use and overall survival (Hazard ratio = 1.02; 95% CI, 0.80 - 1.30) and progressive-free survival (Hazard ratio = 1.00; 95% CI, 0.76 - 1.31). In addition, the summary risk estimates for adverse reactions of metformin were not statistically significant between intervention and control groups (Risk Ratio = 1.11; 95% CI, 0.94 - 1.31). However, metformin use was associated with a reduction in cancer risk (Hazard ratio = 0.90, 95% CI, 0.86 - 0.94).

Conclusion: Metformin does not significantly prolong the overall survival and progressive-free survival of cancer patients, but it may effectively reduce the risk of cancer occurrence.

期刊介绍： Current Cancer Drug Targets aims to cover all the latest and outstanding developments on the medicinal chemistry, pharmacology, molecular biology, genomics and biochemistry of contemporary molecular drug targets involved in cancer, e.g. disease specific proteins, receptors, enzymes and genes. Current Cancer Drug Targets publishes original research articles, letters, reviews / mini-reviews, drug clinical trial studies and guest edited thematic issues written by leaders in the field covering a range of current topics on drug targets involved in cancer. As the discovery, identification, characterization and validation of novel human drug targets for anti-cancer drug discovery continues to grow; this journal has become essential reading for all pharmaceutical scientists involved in drug discovery and development.
