Summary

There has been ongoing debate about the relationship between cancer recurrence and anesthetic management. Therefore, the investigators will test the hypothesis that the recurrence free survival (RFS) after curative resection of NSCLC is higher in patient who received total intravenous anesthesia (TIVA) than volatile anesthetics in this multi-center randomized trials.

Detailed description

Surgery is the primary treatment for non-small cell lung cancer (NSCLC), but microscopic residual disease may be unavoidable. Preclinical studies have shown that volatile anesthetics might suppress host immunity and promote a pro-malignant environment which supports cancer cell proliferation, migration, and angiogenesis, whereas propofol may preserve cell-mediated immunity and inhibits tumor angiogenesis. However, clinical evidence that propofol-based total intravenous anesthesia (TIVA) can reduce tumor recurrence after curative resection remains inconsistent due to retrospective observational nature of previous studies. Therefore, the investigators will test the hypothesis that the recurrence free survival (RFS) after curative resection of NSCLC is higher in patient who received TIVA than volatile anesthetics in this multi-center randomized trials. This double-blind, randomized trial will enroll patients at 22 international sites, subject to study registration, institutional review board approval, and patient written informed consent. Eligible patients are adult patients undergoing lung resection surgery with curative intent for NSCLC. At each study site, enrolled subjects will be randomly allocated into the TIVA and GAS group with a 1:1 ratio. A centralized, password-protected, and encrypted web-based electronic case report form will be used for randomization and data upload. This pragmatic trial does not standardize any aspect of patient care. However, potential confounders will be balanced between the study arms. The primary outcome will be recurrence free survival (RFS). Secondary outcomes will be overall survival and complications within postoperative 7 days. Enrollment of 5384 patients will provide 80% power to detect a 3% treatment effect (hazard ratio of 0.83) at alpha 0.05 for RFS at 3 years. Confirmation of the study hypothesis would demonstrate that a relatively minor and low cost alteration in anesthetic management has the potential to reduce cancer recurrence risk in NSCLC, an ultimately fatal complication. Rejection of the hypothesis would end the ongoing debate about the relationship between cancer recurrence and anesthetic management.
