This study aimed to evaluate the efficacy of postoperative transarterial chemoembolization (TACE) on prognosis of intermediate-stage HCC patients with MVI after curative liver resection (LR) . Materials and methods: Patients who had intermediate-stage HCC with MVI and underwent curative LR between January 2013 and December 2019 at three institutions in China were identified for further analysis. Overall survival (OS) and recurrence-free survival (RFS) were compared between patients treated with and without postoperative TACE by propensity score-matching.  \nResults: A total of 246 intermediate-stage HCC patients with MVI were enrolled, 137 entered into the LR group and 109 entered into the LR+TACE group. The 1-year, 3-year, and 5-year RFS rates were 42 .0, 27 .2, and 17 .8% in LR+TACE group, and 31 .8, 18.2, and 8.7% in LR group. The 1-year, 3-year, and 5-year OS rates were 81.7, 47.2, and 26.1% in the LR+TACE group, and 67.3, 35.6, and 18 .5% in the LR group. Compared with LR alone, LR+TACE was associated with significantly better RFS [hazard ratio (HR), 1 .443; 95% CI: 1 .089–1.914; P = 0.009] and OS (HR, 1 .438; 95% CI: 1 .049–1.972; P = 0.023) . No difference was observed with RFS and OS in single TACE and multiple TACE in the matched cohort.  \nConclusion: Postoperative adjuvant TACE could be beneficial for intermediate-stage HCC patients with MVI.  \nKeywords: hepatocellular carcinoma, liver resection, microvascular invasion, propensity score-matching, transarterial chemoembolization  \nIntroduction  \nHepatocellular carcinoma (HCC) is one of the most common malignancies worldwide and the second leading cause of cancerrelated mortality in China due to endemic chronic hepatitis B virus (HBV) infection[1,2] . Advances in diagnostic imaging and widespread application of screening programs in high-risk populations have allowed detection of HCC at an early-stage, but some patients still present with intermediate-stage HCC[3] . According to the Barcelona Clinic Liver Cancer (BCLC)  \nalgorithm for the treatment of HCC, intermediate-stage (stage B) HCC is defined as extensive multifocal disease confined to the liver without macrovascular invasion in patients with preserved liver function and the absence of cancer-related symptoms[4] . The prognosis of patients with intermediate-stage HCC varies differently with different treatments[5] . Currently, transarterial chemoembolization (TACE) is considered a first-line treatment for patients with intermediate-stage HCC[4] .
