Background and Objectives: While liver transplantation (LT) is a definitive treatment for hepatocellular carcinoma (HCC), tumor recurrence remains a major clinical concern. Although volatile anesthetics influence oncological outcomes, direct comparison between sevoflurane and desflurane remains scarce. This study aimed to investigate the impact of the recipient’s volatile anesthetic choice (sevoflurane vs. desflurane) on HCC recurrence following living donor liver transplantation (LDLT). Materials and Methods: This retrospective cohort study included adult patients who underwent LDLT for HCC. Patients were then divided into sevoflurane and desflurane groups, and propensity score matching (PSM) was used to balance baseline variables. The primary outcome was HCC recurrence, and the secondary outcomes were overall survival (OS) and postoperative C-reactive protein (CRP) levels as a marker for the postoperative systemic inflammatory response. Results: After PSM, 373 matched pairs (n = 746) were analyzed. HCC recurrence was significantly higher in the sevoflurane group compared to the desflurane group (19.6% vs. 13.1%, p = 0.023). Kaplan–Meier analysis also demonstrated that cumulative recurrence of HCC was significantly higher in recipients who received sevoflurane anesthesia than in those who received desflurane (log-rank p = 0.0018). In multivariate Cox proportional hazards regression analysis, the use of sevoflurane for anesthesia maintenance was an independent risk factor forHCC recurrence (Hazard Ratio, 1.66; 95% Confidence Interval, 1.15–2.39; p = 0.007). Regarding OS, no significant difference was observed between the two groups (log-rank p = 0.1123). Postoperative CRP levels were significantly higher in the sevoflurane group compared to the desflurane group, suggesting a more intense systemic inflammatory response associated with sevoflurane maintenance. Conclusions: For HCC patients undergoing LDLT, anesthesia maintenance with desflurane is associated with a reduced risk of tumor recurrence compared to sevoflurane, without a significant impact on overall survival.
