Summary

1. Eligible participants were assessed prior to anesthesia. After the patient is admitted to the hospital, the subject's consent form is explained, and the consent form must be signed before the operation. 2. This is a two-arm, parallel-group randomized clinical trial.In the preoperative waiting area, the patients are randomly assigned and divided into two groups according to the allocation sequence table (corresponding to 1:1 randomization) generated by the computer. The propofol group was both induced and maintained at an effect-site concentration (Ce) of 2.0-4.0 mcg/mL by a target-controlled infusion (TCI) system. The sevoflurane group was maintained via sevoflurane vaporizer between 1% and 3% (target minimum alveolar concentration of 0.7-1.3). During the operation, the dose of anesthetic drugs (propofol/fentanyl /remifentanil and sevoflurane/cisatracurium/rocuronium) are adjusted to maintain the mean arterial pressure and heartbeat fluctuations within 20% of the baseline value and Entropy (or BIS) value at 40-60in both groups. The following patient data were recorded, the type of anesthesia, sex, age at the time of surgery, preoperative Karnofsky performance status (KPS) score and functional capacity, the postoperative complications within 30 days (according Clavien-Dindo classification), ASA physical status scores, tumor marker ,tumor size, intraoperative blood loss/transfusion, duration of surgery, duration of anesthesia, total opioid (remifentanil/fentanyl) use, postoperative radiation therapy, postoperative chemotherapy, postoperative concurrent chemoradiotherapy, the presence of disease progression, and 6-month, 1-year, 3-year and 5-year overall survival and Karnofsky performance status score were recorded.

Detailed description

During the operation, the dose of anesthetic drugs (propofol/ fentanyl /remifentanil and sevoflurane/ cisatracurium/ rocuronium) are adjusted to maintain the mean arterial pressure and heartbeat fluctuations within 20% of the baseline value and Entropy (or BIS) value at 40-60in both groups. The following patient data were recorded, the type of anesthesia, age at the time of surgery, preoperative Karnofsky performance status (KPS) score and functional capacity, the postoperative complications within 30 days (according Clavien-Dindo classification), ASA physical status scoress, tumor marker , tumor size, intraoperative blood loss/transfusion, duration of surgery, duration of anesthesia, total opioid (remifentanil/ fentanyl/ propofol) use, postoperative radiation therapy, postoperative chemotherapy, postoperative concurrent chemoradiotherapy, the presence of disease progression, and 6-month, 1-year, and 3-year overall survival and Karnofsky performance status score were recorded.
