The value of preoperative transcatheter arterial chemoembolization (TACE) for patients with recurrent hepatocellular carcinoma (rHCC) after liver resection is uncertain. We aimed to determine its effect on postoperative complication and survival. There were 33 patients who received preoperative TACE and repeated liver resection (TACE-LR) and 119 patients who received repeated liver resection (LR) alone for rHCC. Seventy-eight patients (TACE-LR, 28; LR, 50) were identified by propensity score matching (PSM) analysis for comparison of postoperative complication, disease-free survival (DFS) and overall survival (OS). Univariable and multivariable analyses were used to identify predictors for survival. Before matching, the TACE-LR group had more intraoperative blood loss than the LR group (P < 0.05). After matching, the TACE-LR group had more intraoperative blood loss and a longer operation time (Both P < 0.05). In all and matched patients, both groups had similar postoperative complications rate (TACE-LR, 21.2%; LR, 7.6%; P = 0.052 and TACE-LR, 21.4%; LR, 12.0%; P = 0.435), DFS (P = 0.81 and P = 0.41) and OS (P = 0.87 and P = 0.79). Preoperative TACE was not a predictor for DFS and OS in multivariable analyses. Preoperative TACE for resectable rHCC prolongs operating time and increases intraoperative blood loss without improving survival; thus, it should not be recommended as a routine procedure before repeated resection for patients with rHCCs.
