The outcome of intravenous and inhalation anesthesia after pancreatic cancer resection: a retrospective study

Background: Different types of anesthesia may affect cancer patient’s outcomes, we compared the overall survival (OS) and disease-free survival (DFS) of patients with pancreatic cancer under total intravenous and inhalation anesthesia. Methods: : The authors collected the electronic medical records of patients who had accepted at a pancreatectomy from January 1, 2010 to December 31, 2016. Patients respectively received total intravenous anesthesia (TIVA) or inhalational anesthesia (INHA). Stabilized inverse probability of treatment weighting (SIPTW)was used to minimize differences. Kaplan-Meier survival was established to analyze the influence of sort of anesthesia on disease-free and overall survival. We compare the effects of each sort of anesthesia on cancer recurrence or metastasis and all-cause mortality. Results: : A total of 463 patients who had undergone pancreatic cancer resection were collected in this study, of which 442 patients were available (TIVA group, n=323, INHA group, n=119). After SIPTW there were no significant differences between the two groups in disease-free survival (hazard ratio, 1.00, 95%CI, 0.79 to 1.27, P =0.995) or overall survival (hazard ratio, 1.10, 95%CI, 0.86 to 1.41, P =0.433). Conclusions: : In conclusion, the present study showed no significant difference in overall survival and disease-free survival between total intravenous anesthesia and volatile anesthesia.
