Abstract
Prostate cancer has become a major health problem in men. Its incidence is increasing as the average age of the affected population tends to be higher. Of all the possible treatments, surgery is the gold standard in its treatment. Surgery produces a deregulation in the immune system that can favour the development of distant metastases. Different anesthetic techniques have raised the hypothesis that different anesthetic drugs influence tumor recurrence and prognosis. Some mechanisms are beginning to be understood by which halogenated agents in cancer patients and the use of opioids may negatively affect patients. In this document, we group together all the available evidence on how the different anesthetic drugs affect tumor recurrence in prostate cancer.
