BackgroundPrevious researches have shown that anesthetic techniques may influence the patients' outcomes after cancer surgery. Here, we studied the relationship between the type of anesthetic techniques and patients' outcomes following elective robot-assisted radical prostatectomy.MethodsThis was a retrospective cohort study of patients who received elective, robot-assisted radical prostatectomy between January 2008 and December 2018. Patients were grouped according to the anesthesia they received, namely desflurane or propofol. A Kaplan-Meier analysis was conducted, and survival curves were presented from the date of surgery to death. Univariable and multivariable Cox regression models were used to compare hazard ratios for death after propensity matching. Subgroup analyses were performed for tumor-node-metastasis stage and disease progression. The primary outcome was overall survival, and the secondary outcome was postoperative biochemical recurrence.ResultsA total of 365 patients (24 deaths, 7.0%) under desflurane anesthesia, and 266 patients (2 deaths, 1.0%) under propofol anesthesia were included. The all-cause mortality rate was significantly lower in the propofol anesthesia than in the desflurane anesthesia during follow-up (P = 0.001). Two hundred sixty-four patients remained in each group after propensity matching. The propofol anesthesia was associated with improved overall survival (hazard ratio, 0.11; 95% confidence interval, 0.03-0.48; P = 0.003) in the matched analysis. Subgroup analyses showed that patients under propofol anesthesia had less postoperative biochemical recurrence than those under desflurane (hazard ratio, 0.20; 95% confidence interval, 0.05-0.91; P = 0.038) in the matched analysis.ConclusionsPropofol anesthesia was associated with improved overall survival in robot-assisted radical prostatectomy compared with desflurane anesthesia. In addition, patients under propofol anesthesia had less postoperative biochemical recurrence.
