Don't Judge a Book by Its Cover: The Role of Statins in Liver Cancer

Simple Summary Statins are a group of remedies developed to treat lipid disorders associated with cardiovascular diseases. Thanks to their high efficiency, they are the primary line of therapy for hypercholesterolemia. However, recent experimental and clinical studies indicate the potential use of statins in treating liver cancer. In this review, we discuss these aspects, bringing the reader closer to the importance of statins as a pharmacological tool in cancer prevention and the therapeutic management of the liver and bile duct neoplasm.Abstract Statins, which are inhibitors of 3-hydroxy-3-methyl-glutaryl-coenzyme A (HMG-CoA) reductase, are an effective pharmacological tool for lowering blood cholesterol levels. This property makes statins one of the most popular drugs used primarily to prevent cardiovascular diseases, where hyperlipidemia is a significant risk factor that increases mortality. Nevertheless, studies conducted mainly in the last decade have shown that statins might prevent and treat liver cancer, one of the leading causes of cancer-related mortality worldwide. This narrative review summarizes the scientific achievements to date regarding the role of statins in liver tumors. Molecular biology tools have revealed that cell growth and proliferation can be inhibited by statins, which further inhibit angiogenesis. Clinical studies, supported by meta-analysis, confirm that statins are highly effective in preventing and treating hepatocellular carcinoma and cholangiocarcinoma. However, this effect may depend on the statin's type and dose, and more clinical trials are required to evaluate clinical effects. Moreover, their potential hepatotoxicity is a significant caveat for using statins in clinical practice. Nevertheless, this group of drugs, initially developed to prevent cardiovascular diseases, is now a key candidate in hepato-oncology patient management. The description of new drug-statin-like structures, e.g., with low toxicity to liver cells, may bring another clinically significant improvement to current cancer therapies.

Automated summary

Statins, originally developed for cardiovascular diseases, have been shown to have potential use in treating liver cancer, one of the leading causes of cancer-related deaths.
