Metformin in breast cancer: preclinical and clinical evidence Curr Probl Cancer. 2013;109:2792–7.DeCensi A, Puntoni M, Gandini S, Guerrieri-Gonzaga A, Johansson HA, Cazzaniga M, et al. This study represents an important step forward in establishing one of several possible mechanisms for metformin, information that will be useful in determining candidate biomarkers to evaluate in large clinical trials of metformin, such as the ongoing NCIC CTG MA.32 trial of adjuvant metformin. Metformin has been the first-line drug for the treatment of type II diabetes mellitus for decades, being presently the most widely prescribed antihyperglycemic drug. By using this website, you agree to our eCollection 2020.Diabetol Metab Syndr. Cancer Prev Res (Phila). Metformin exhibits pleotropic effects, which may have beneficial effects on a variety of tissues independent of glucose control. It is the first line pharmacotherapy for glucose control in patients with Type 2 diabetes due to its safety, efficacy and tolerability.

Metformin is a lipophilic biguanide which inhibits hepatic gluconeogenesis and improves peripheral utilization of glucose. The data suggest that short-term administration of metformin in this setting has anti-tumor effects significantly involving the indirect, insulin-dependent pathway.

Moreover, metformin significantly reduces breast cancer risk, compared to patients who are not using metformin and is independent of diabetes status. Several trials have attempted to address this knowledge gap (Table By binding to its receptor, insulin has been shown to have mitogenic and anti-apoptotic effects in several cancers, including breast cancer, and circulating insulin is associated with increased cancer risk and prognosis [The decreases in Akt and ERK1/2 phosphorylation are in agreement with previous Metformin can also exert its anti-tumor activity through insulin-independent direct actions on cancer cells.
