AbstractCancer is a leading cause of morbidity and mortality worldwide. In light of demographic changes among other factors, it is anticipated this trend will continue. Surgical resection is the primary method of treating solid tumours. Unfortunately, even with the use of adjunct therapies, metastatic disease is a leading cause of death in people with cancer. Recent evidence suggests choice of anesthetic technique may influence cancer outcome. This review considers the latest evidence regarding local and regional anesthesia in the context of cancer biology. There is a focus on the indirect and direct mechanisms involved. An integrated approach is used such that diverse areas of research are explored; ranging from epigenetics to cell death pathways. With a better understanding of how regional anesthesia and/or local anesthetics interact with cancer cells, these techniques can be trialed and evaluated to ascertain potential clinical benefits in cancer patients. Thus far, there is insufficient evidence to warrant a change in clinical practice.© 2014 UICC.
