The Impact of Inhalation vs Total Intravenous Anesthesia on the Immune Status and Mortality in Patients Undergoing Breast Cancer Surgery: a Prospective Double-Blind Randomized Clinical Trial.

Summary

Even decade ago it was believed that the choice method of anesthesia did not affect the course of the oncological process, but recent evidence has begun to emerge that inhalation anesthesia vs TIVA is associated with a higher number of adverse outcomes. Apparently, it makes sense to conduct mRCT in order to assess the effect of IA on immune system in patients operated on for breast cancer comprehensively. The results of that kind of RCT may finally give us an answer whether the choice of anesthesia affects the immune status of patients undergoing surgery for breast cancer. The evaluation of complications and long-term survival will allow to recommend to use or not to use IA for this type of surgery. Objective: The Impact of Inhalation vs Total Intravenous Anesthesia on the Immune Status and Mortality in Patients Undergoing Breast Cancer Surgery
