Advances and controversies of statins application in prevention and treatment of hepatocellular carcinoma

Abstract

Statins, as lipid-regulating drugs, have been widely used in the treatment for hyperlipidemia and the primary and secondary prevention of cardio-cerebrovascular diseases. Hepatocellular carcinoma (HCC) is a serious burden of liver disease in China with poor prognosis, thus effective adjuvant drug used for HCC treatment has attracted much attention. Statins can suppress tumor growth, decrease the risk of tumorigenesis and postoperative recurrence of HCC, extend the survival time and improve the therapeutic effect of other treatment, therefore might increase the benefit obtained by the HCC patients. Statins also can impact the expression of MAPK/ERK signaling pathway, promote the apoptosis of malignant cells and ameliorate the HCC risk of hepatitis B virus infected patients. Statins not only prevents the HCC, but also has part therapeutic effect on the different stage of HCC. Although it can't replace the operation, radiofrequency ablation, molecular targeted treatment and immunotherapy currently, statins may be a potential adjuvant drug to provide clinical benefit for HCC patients. The advancement of statins application in the prevention and treatment of HCC has attracted more attention recently, however, discussion and controversy also existed about whether it can eventually become an adjuvant therapy for HCC. The purpose of this paper is to summarize and comment on the new development and disputes of statins application in the prevention and treatment of HCC in recent years, to provide help for the future clinical practice.
