Comparison of drug-eluting bead with conventional transcatheter arterial chemoembolization for hepatocellular carcinoma with portal vein tumor thrombus: a randomized clinical trial.

Drug-eluting bead transarterial chemoembolization (DEB-TACE) has shown efficacy for treating hepatocellular carcinoma (HCC) with portal vein tumor thrombus (PVTT). However, whether DEB-TACE is superior to conventional TACE (cTACE) remains unclear. This randomized controlled trial aimed to compare the efficacy and safety of DEB-TACE versus cTACE in treating HCC with PVTT. The study was conducted at a tertiary care center in Southeast China. HCC patients with PVTT were randomized at a 1:1 ratio into the DEB-TACE or cTACE groups. The primary endpoint was progression-free survival (PFS), and the secondary endpoints were overall survival (OS) and the incidence of adverse events (AEs). An independent review committee assessed the radiologic response according to the modified Response Evaluation Criteria in Solid Tumors (mRECIST). AEs were assessed by the Common Terminology Criteria for Adverse Events (CTCAE) version 4.0. Systemic therapies were not restricted. Between September 2018 and July 2020, 163 patients were randomized to undergo DEB-TACE ( n =82) or cTACE ( n =81). Nine patients were excluded, and 154 patients were included in the final analysis; the median age was 55 years (range, 24-78 years), and 140 (90.9%) were male. The median PFS in the DEB-TACE group was 6.0 months (95% CI, 5.0-10.0) versus 4.0 months (95% CI, 3.0-5.0) in the cTACE group (hazard ratio, 0.63; 95% CI, 0.42-0.95; P =0.027). The DEB-TACE group showed a higher response rate [51 (66.2%) vs. 36 (46.8%); P =0.0015] and a longer median OS [12.0 months (95% CI, 9.0-16.0) vs. 8.0 months (95% CI, 7.0-11.0), P =0.039] than the cTACE group. Multivariate analysis showed that the treatment group, ALBI score, distant metastasis and additional TKIs were the four independent prognostic factors correlated with PFS. In addition, the treatment group, PVTT group and combination with surgery were independently associated with OS. AEs were similar in the two groups, and postembolization syndrome was the most frequent AE. DEB-TACE is superior to cTACE in treating HCC patients with PVTT, demonstrating improved PFS and OS with an acceptable safety profile, and may thus emerge as a promising treatment strategy for HCC patients with PVTT.

Hepatic artery infusion chemotherapy combined with camrelizumab plus rivoceranib for hepatocellular carcinoma with portal vein tumor thrombosis: a multicenter propensity score-matching analysis.

Portal vein tumor thrombosis (PVTT) signifies late-stage hepatocellular carcinoma (HCC) with high-risk progression and poor prognosis. As a standard treatment, sorafenib monotherapy has limited the efficacy in managing HCC with PVTT. Currently, both hepatic arterial infusion chemotherapy (HAIC) and the combination of camrelizumab and rivoceranib have shown favorable survival benefits for advanced HCC, surpassing the standard sorafenib treatment. In this study, we investigate the safety and efficacy of HAIC combined with camrelizumab and rivoceranib in treating HCC patients with PVTT. From January 2020 to December 2021, HCC patients with PVTT, who received either a triple regime of HAIC combined with camrelizumab and rivoceranib or a dual regime of camrelizumab and rivoceranib as their first-line treatment, were reviewed for eligibility at four hospital centers in China. To balance any intergroup differences, propensity score matching (PSM) was applied. The aim of this study is to compare the efficacy of the dual and triple combination treatment regimens based on survival prognosis and tumor response and evaluate the safety based on the occurrence of adverse reactions. In this study, a total of 411 patients who received either the triple treatment regime (HAIC combined with camrelizumab plus rivoceranib, referred to as the HAICCR group, n = 292) or the dual treatment regime (camrelizumab combined with rivoceranib, referred to as the CR group, n = 119) between January 2020 and December 2021 were included. The results showed that the HAICCR group exhibited significantly better overall survival (mOS: 19.60 months vs. 11.50 months, p < 0.0001) and progression-free survival (mPFS: 10.0 months vs. 5.6 months, p < 0.0001) compared to the CR group in the overall cohort. Moreover, the HAICCR group also had a significantly higher ORR (objective response rate, 55.5% vs. 42.0%, p = 0.013) and DCR (disease control rate, 89.0% vs. 79.0%) compared to the CR group. After PSM, a final matched cohort of 83 pairs was obtained, and the survival benefits were consistent in this cohort as well (mOS: 18.70 months vs. 11.0 months, p < 0.0001; mPFS: 10.0 months vs. 5.6 months, p < 0.0001). However, there was no significant difference in the ORR between the triple and dual combination regimes. Univariate and multivariate analysis showed that CTP (Child-Turcotte-Pugh) stage, ALBI (albumin-bilirubin index) grade, tumor number, and treatment regime were significant risk factors affecting overall survival, while AFP (α-fetoprotein) level, tumor number, metastasis, and treatment regime were significant risk factors affecting progression-free survival. As for safety, hypertension and hand-foot syndrome were the two most common adverse reactions in both groups, with no significant difference in the occurrence of adverse reactions between the two groups (p < 0.05). In the context of advanced HCC patients with PVTT, the combination regime of HAIC and camrelizumab plus rivoceranib demonstrates more excellent capacity for prolonging survival and offers a well-tolerated safety compared to the CR dual therapy approach. This triple regime represents a therapeutic modality of broad prospects and vast potential for HCC patients with PVTT.

Lenvatinib plus drug-eluting bead transarterial chemoembolization with/without hepatic arterial infusion chemotherapy for hepatocellular carcinoma larger than 7 cm with major portal vein tumor thrombosis: a multicenter retrospective cohort study.

The management of hepatocellular carcinoma (HCC) with high tumor burden and major portal vein tumor thrombosis (PVTT) remains a great challenge. We aimed to investigate the efficacy and safety of lenvatinib plus drug-eluting bead transarterial chemoembolization (DEB-TACE) and hepatic arterial infusion chemotherapy (HAIC) with oxaliplatin, fluorouracil and leucovorin (Len+DEB-TACE+HAIC) versus lenvatinib plus DEB-TACE (Len+DEB-TACE) for HCC > 7.0 cm accompanied with major PVTT. This multicenter retrospective cohort study evaluated consecutive patients with HCC (> 7.0 cm) and major PVTT who received Len+DEB-TACE+HAIC (Len+DEB-TACE+HAIC group) or Len+DEB-TACE (Len+DEB-TACE group) between July 2019 and June 2021 from eight institutions in China. Objective response rate (ORR), time to progression (TTP), overall survival (OS), and treatment-related adverse events (TRAEs) were compared between the two groups by propensity score-matching (PSM). A total of 205 patients were included. After PSM, 85-paired patients remained in the study cohorts. Patients in the Len+DEB-TACE+HAIC group had higher ORR (61.2% vs. 34.1%, P < 0.001), longer TTP (median, 9.8 vs. 5.9 months, P < 0.001), and prolonged OS (median, 16.7 vs. 12.5 months, P < 0.001) than those in the Len+DEB-TACE group. The ORR and TTP of both intrahepatic tumor (ORR: 64.7% vs. 36.5%, P < 0.001; median TTP: 10.7 vs. 7.0 months, P < 0.001) and PVTT (ORR: 74.1% vs. 47.1%, P < 0.001; median TTP: 17.4 vs. 7.6 months, P < 0.001) were better in the Len+DEB-TACE+HAIC group than the Len+DEB-TACE group. The frequency of grade 3-4 TRAEs in the Len+DEB-TACE+HAIC group were comparable to those in the Len+DEB-TACE group (38.8% vs. 34.1%, P = 0.524). The addition of HAIC to Len+DEB-TACE significantly improved ORR, TTP, and OS over Len+DEB-TACE with an acceptable safety profile for large HCC with major PVTT.

Lipiodol combined with drug-eluting beads versus drug-eluting beads alone for transarterial chemoembolization of hepatocellular carcinoma: a multicenter study.

This study aimed to propose a novel approach of lipiodol combined with drug-eluting beads transarterial chemoembolization (Lipiodol-DEB TACE) and to compare the safety and efficacy with DEB-TACE alone for patients with unresectable hepatocellular carcinoma (HCC). From the database of four centers, the records of patients with HCC who received DEB-TACE or Lipiodol-DEB TACE as initial treatment were retrospectively evaluated. The tumor response was measured based on the Modified Response Evaluation Criteria in Solid Tumors. Overall survival (OS), progression-free survival (PFS) and adverse events (AEs) were compared between two groups. A total of 244 patients were included with 160 patients receiving DEB-TACE and 84 patients receiving Lipiodol-DEB TACE. Lipiodol-DEB TACE group had higher objective response rate (86.9 % vs. 76.3 %), higher disease control rate (97.6 % vs. 88.8 %), longer median OS (42.6 vs. 25.8 months) and longer median PFS (34.0 vs. 17.0 months) than DEB-TACE group (P < 0.05). There was no significant difference observed in the incidence of AEs between two groups. Cox analysis identified total bilirubin level, maximum tumor diameter, TACE method and portal vein invasion as independent prognostic factors. Lipiodol-DEB TACE was a safe option and associated with improved tumor response and survival outcome compared to DEB-TACE alone for selected patients with HCC.
