Perioperative Immunosuppression and Risk of Cancer Progression: The Impact of Opioids on Pain Management

Abstract: Opioids comprise an important group of drugs used in cancer pain pharmacotherapy. In recent years, more and more studies have emerged indicating the potentially immunosuppressive effects of opioid analgesics and their serious consequences, including the risk of cancer progression. The identification of these risks has prompted a search for other effective, and most importantly, safer methods of perioperative analgesic management. Regional analgesia techniques, which allow for a significant reduction in opioid … Show more

“…The main mechanisms responsible for this effect are the stimulation of angiogenesis and immunosuppression, mainly mediated by agonism at MOR [66]. Studies have suggested that morphine has the greatest immunosuppressive potential, and fentanyl has intermediate potential, whereas buprenorphine and tramadol have shown the lowest or no immunosuppressive effect [67]. Experimental studies have shown that KOR agonists are efficacious in the treatment of CIBP in mice, without changing tumor size or proliferation in cancer cell lines.…”

“…The acute and chronic administration of exogenous opioids appear to affect the body's cell mediated and humoral immune response. Exogenous opioids have a significant effect on several components of the immune system including lymphocyte proliferation., phagocytic activity, natural killer cell activity, cytokine expression and antibody production [8,9].…”

“…[ 4 , 13 ] The use of RA has been reported to reduce the dose of opioids and thus minimize the risk of immune suppressive effect of opioids. [ 14 ] However, in the present study and even within RA patients, opioids were extensively administered to control pain in the perioperative period. However, the immunosuppressive effects of opioids have been reported in many previous and recent studies.…”
