Statins and colorectal cancer
Abstract
Statins are naturally occurring compounds that inhibit the enzyme 3-hydroxy-3-methyl-glutaryl-CoA reductase. Through their beneficial management of the body’s lipid metabolism, they are widely used medicinal drugs employed extensively in the primary and secondary prevention of cardiovascular disease. In addition, many studies to date have shown the therapeutic advantages derived from using statins in conditions such as endometriosis, osteoporosis, polycystic ovary syndrome and rheumatic disease. Due to the steady increase of cancer morbidity rates, as demonstrated by epidemiological data, the putative role of statins in treating or preventing cancer has been ever more frequently investigated; including for colorectal cancer. This paper attempts to bring together current knowledge/ evidence on statin therapy targeted at the development, disease course and treatment of colorectal cancer, both in terms of epidemiological findings and clinical observations. Because of the reported link between metabolic disorders and the development of colorectal cancer, particular focus is given to the effects of statins on signalling pathways involving insulin-like growth factors (IGFs).
