Anesthetics and analgesics used during the perioperative period may modulate the innate and adaptive immune system, inflammation and angiogenesis, and have a direct effect on cancer cells that could ultimately modify oncological outcomes. For instance, volatile anesthetics and opioid analgesics have shown predominantly pro-tumor effects, while propofol, non-steroid anti-inflammatory drugs have mostly anticancer effects. Researchers have been especially interested in investigating the association between the use of regional anesthesia techniques and the postoperative survival of patients with cancers. Since the results of the current retrospective studies are conflicting, several researchers are conducting prospective randomized trials. ER -
