    Abstract:
    BACKGROUND: About 55% of hepatocellular carcinoma (HCC) cases in China are advanced HCC at the initial diagnosis. We aimed to evaluate the efficacy and safety of hepatic arterial infusion chemotherapy (HAIC) for HCC with portal vein tumor thrombosis (PVTT) compared to transcatheter arterial chemoembolization (TACE) after propensity score matching (PSM). METHODS: A propensity score-matched cohort study was performed in patients with advanced HCC with PVTT who underwent either HAIC using oxaliplatin plus raltitrexed or TACE at three institutions between January 2016 and January 2021. Overall survival (OS), progression-free survival (PFS), objective response rate (ORR), and adverse events were compared between the groups. RESULTS: After PSM, 44 pairs of patients were assessed. The HAIC group had longer OS (11.2 [95% confidence interval [CI]: 9.9-12.5] vs. 9.0 [95% CI: 5.3-12.7] months; p = 0.010), better PFS (5.6 [95% CI: 3.7-7.9] vs. 2.0 [95% CI: 1.3-2.7] months; p = 0.006), and a higher ORR (Response Evaluation Criteria in Solid Tumors [version 1.1]: 56.8% vs. 18.2%; p < 0.001) than the TACE group. In multivariate analysis, HAIC was identified as an independent favorable prognostic factor for survival. CONCLUSIONS: Compared to TACE, HAIC significantly increased the ORR of HCC with portal invasion and prolonged survival without causing a significant increase in severe adverse events.
