Statin as Repurposed Drug in Ovarian Cancer: A Comprehensive Review

Abstract

Abstract: With a prevalence rate of 6.6 per 100,000 women, ovarian cancer is the third most lethal gynecological tumor in the world. Several factors like family history, nulliparity, late menopause, genetic mutation, and an unhealthy lifestyle contribute to increasing the risk of ovarian cancer development. Novel research studies suggest that ovarian cancer may be caused by changes in the lipid metabolic profile that trigger inflammatory responses. Moreover, ovarian cancer patients will eventually experience chemoresistance. Statin, a competitive inhibitor of HMG-CoA reductase that is a lipid-lowering drug with pleiotropic effects, seems to be the best choice to deal with this therapeutic issue. The aim of this review is to highlight the pharmacotherapeutic potential of statins, especially the repurposing of statin drugs for antitumor mechanisms. This review will also provide a brief summary of the meta-analysis, and case-control observational studies carried out to examine the impact of statins on risk reduction and survival in ovarian cancer patients. Furthermore, this review will discuss the nanotechnological approach for improving the drug's bioavailability and safe and targeted delivery with controlled release of active ingredients, making statins more effective in preventing and treating ovarian cancer.
