Purpose: Anesthetic agents affect the biological behavior of tumor cells and long-term oncologic outcomes. We investigated the association of anesthetics and 5-year survival of colon cancer patients.
Methods: The data from patients underwent colon cancer surgery from July 01st, 2009 to July 31st, 2014 were analyzed. Patients were grouped according propofol or sevoflurane used during surgery. Five-year survivals were analyzed with Kaplan-Meier method, and Cox regression models were used to identify risk factors of death.
Results: Of 1,289 colon cancer patients, 913 patients with propofol anesthesia and 376 with sevoflurane anesthesia were eligible for analysis. After propensity score matching, 375 patients remained in each group, and 5-year overall survival was 79.7% (95% Confidence Interval [CI], 0.76-0.84) in the propofol group, and 78.1% (95% CI, 0.74-0.82) in the sevoflurane group, and 5-year
recurrence-free survival was 73.4% (95% CI, 0.69-0.78) and 70.4% (95% CI, 0.66-0.75), respectively. Type of anesthetic did not affect 5-year overall survival and recurrence-free survival with the logrank test (P=0.513, 0.293, respectively). Related risk factors were age, anesthesia duration, open surgery, CEA and CA199 values, vascular or nerve infiltration, TNM, and adjuvant therapy.
Conclusion: There were no benefits in 5-year survival in propofol anesthesia vs. sevoflurane anesthesia after colon cancer surgery.
