Clinical Importance of Regimens in Hepatic Arterial Infusion Chemotherapy for Advanced Hepatocellular Carcinoma with Macrovascular Invasion.

ABSTRACT: Macroscopic vascular invasion (MVI) is a poor prognostic factor in hepatocellular carcinoma (HCC). Hepatic arterial infusion chemotherapy (HAIC) is a promising treatment in MVI-HCC. However, it is not clear which regimens are suitable for HAIC. In this study, we aimed to compare the therapeutic effects between New FP (a fine-powder cisplatin suspended with lipiodol plus 5-fluorouracil) and low dose FP (LFP/cisplatin plus 5-fluorouracil) in the treatment of MVI-HCC patients with Child-Pugh class A. New FP is a regimen that consists of a fine-powder cisplatin suspended with lipiodol and 5-fluorouracil. Fifty-one patients were treated with LFP, and 99 patients were New FP. We compared the therapeutic effects of LFP and New FP and assessed factors that associated with the therapeutic effects. The median survival and progression-free survival times of LFP and New FP were 16.1/24.7 and 5.4/8.8 months, respectively (p < 0.05, p < 0.05). The complete response (29%) and objective response rate (76%) of New FP were significantly higher than those of LFP (p < 0.001, p < 0.01). Factors associated with better therapeutic response were better ALBI-grade and New FP treatment choice. New FP is a more powerful regimen than LFP in HAIC for MVI-HCC. New FP represents a recommended HAIC regimen for the treatment of patients with MVI-HCC.

Project description:BackgroundThe presence of vascular invasion is associated with poor survival in advanced hepatocellular carcinoma (HCC). We compared the effectiveness of hepatic arterial infusion chemotherapy (HAIC) and immune checkpoint inhibitors (ICIs), alone or in combination, in patients with advanced HCC.MethodsWe retrospectively reviewed medical records of adult patients with unresectable HCC and macrovascular invasion (MVI) who were treated with HAIC or ICIs alone or in combination at a single centre in Taiwan. Overall tumour response, vascular thrombi response, overall survival (OS) and progression-free survival (PFS) in 130 patients were analysed.ResultsThe treatment group showed no significant effect on the overall tumour response [objective response rate (ORR), 22.86% for HAIC, 26.09% for ICI, 50.00% for HAIC+ICI; P=0.111], but showed a significant effect on vessel response (objective response rate of tumour thrombi (ORRT), 38.57% for HAIC, 45.65% for ICI, 78.57% for HAIC+ICI; P=0.023). Post-hoc comparisons followed by Bonferroni correction revealed that vessel ORRT was significantly different between the HAIC+ICI and HAIC groups (P=0.014). A significant effect of treatment group on portal vein tumour thrombus (PVTT) was also detected (ORRT, 40.00% for HAIC, 50.00% for ICI, 90.00% for HAIC; P=0.013), with significant difference between the HAIC+ICI and HAIC groups (P=0.005). Patients treated with HAIC, ICI, and HAIC+ICI respectively had 12-month OS rates of 44.9%, 31.4%, and 67.5% (P=0.127) and 12-month PFS rates of 21.2%, 24.6%, and 33.2% (P=0.091). In multivariate analysis of PFS, HAIC+ICI was associated with reduced risk of progression or death compared with HAIC alone (adjusted hazard ratio: 0.46; 95% confidence interval: 0.23-0.94; P=0.032).ConclusionsHAIC combined with ICIs had a superior response of PVTT compared to HAIC alone, and was associated with reduced risk of progression or death. Future studies are needed to address the survival benefit of the combination therapy in advanced HCC with MVI.

Project description:Purpose: Immunotherapy combined with chemotherapy have synergistic effects in multiple malignancies. We aimed to compare the efficacy and safety of toripalimab plus hepatic arterial infusion chemotherapy (HAIC) of oxaliplatin, fluorouracil, and leucovorin versus lenvatinib in advanced hepatocellular carcinoma (HCC). Materials and Methods: We conducted this retrospective study at 3 hospitals in China and eligible patients were 18 years or older and had a primary diagnosis of unresectable HCC with macroscopic vascular invasion and/or extrahepatic spread. These patients were treated with toripalimab plus HAIC or lenvatinib monotherapy. The primary endpoint was progression-free survival (PFS) and the secondary endpoints were overall survival (OS), disease control rate per response evaluation criteria in solid tumors (RECIST) 1.1, and objective response rate (ORR) per RECIST 1.1. The results were compared by Student's test or the chi-square test, and the survival curves were calculated by the Kaplan-Meier method, and propensity-score matching (PSM) was used to reduce bias. Results: A total of 118 patients were recruited for this study: 53 in the TorHAIC group and 65 in the lenvatinib group. We found that the TorHAIC group showed a longer PFS (9.3 [95% CI, 7.81-10.8] vs 4.8 months [95% CI, 3.31-6.29]; hazard ratio [HR] = 0.57, 95% CI, 0.38-0.85; p = .006), a longer OS (17.13 [95% CI, 13.99-20.27] vs 10.1 months [95% CI, 8.14-12.06]; HR = 0.5, 95% CI, 0.31 - 0.81; p = .005), a higher disease control rate (86.8% vs 69.2%, p = .002) and a higher ORR (47.2% vs 9.2%, p < .001) by RECIST criteria than the lenvatinib group. Both toripalimab plus HAIC and lenvatinib had acceptable safety profiles. No treatment-related deaths occurred in this study. In the propensity score-matched cohorts (47 pairs), the outcomes in the TorHAIC group were also better than those in the lenvatinib group (p < .05). Conclusion: Toripalimab plus HAIC was tolerable and effective in advanced HCC and the result needs to be confirmed in the phase III trial.

Project description:BackgroundLenvatinib is the first-line treatment for advanced hepatocellular carcinoma, but prognosis is still unsatisfactory. Recently, hepatic arterial infusion chemotherapy (HAIC), and immune checkpoint inhibitors showed promising results for advanced hepatocellular carcinoma. Considering different anti-malignancy mechanisms, combining these three treatments may improve outcomes. This study aimed to compare the efficacy and safety of lenvatinib, toripalimab, plus HAIC versus lenvatinib for advanced hepatocellular carcinoma.MethodsThis was a retrospective study including patients treated with lenvatinib [8 mg (⩽60 kg) or 12 mg (>60 kg) once daily] or lenvatinib, toripalimab plus HAIC [LeToHAIC group, lenvatinib 0-1 week prior to initial HAIC, 240 mg toripalimab 0-1 day prior to every HAIC cycle, and HAIC with FOLFOX regimen (oxaliplatin 85 mg/m2, leucovorin 400 mg/m2, 5-fluorouracil bolus 400 mg/m2 on day 1, and 5-fluorouracil infusion 2400 mg/m2 for 46 h, every 3 weeks)]. Progression-free survival, overall survival, objective response rate, and treatment-related adverse events were compared.ResultsFrom February 2019 to August 2019, 157 patients were included in this study: 71 in the LeToHAIC group and 86 in the lenvatinib group. The LeToHAIC group showed longer progression-free survival (11.1 versus 5.1 months, p < 0.001), longer overall survival (not reached versus 11 months, p < 0.001), and a higher objective response rate (RECIST: 59.2% versus 9.3%, p < 0.001; modified RECIST: 67.6% versus 16.3%, p < 0.001) than the lenvatinib group. In addition, 14.1% and 21.1% of patients in the LeToHAIC group achieved complete response of all lesions and complete response of the intrahepatic target lesions per modified RECIST criteria, respectively. Grade 3/4 treatment-related adverse events that were more frequent in the LeToHAIC group than in the lenvatinib group included neutropenia (8.5% versus 1.2%), thrombocytopenia (5.6% versus 0), and nausea (5.6% versus 0).ConclusionsLenvatinib, toripalimab, plus HAIC had acceptable toxic effects and might improve survival compared with lenvatinib alone in advanced hepatocellular carcinoma.
