Patients with hepatocellular carcinoma extrahepatic metastases can benefit from hepatic arterial infusion chemotherapy combined with lenvatinib plus programmed Death-1 inhibitors.

ABSTRACT:

Background

Lenvatinib plus Programmed Death-1 (PD-1) inhibitors (LEN-P) have been recommended in China for patients with advanced hepatocellular carcinoma (HCC). However, they provide limited survival benefits to patients with extrahepatic metastases. We aimed to investigate whether combining hepatic arterial infusion chemotherapy (HAIC) with LEN-P could improve its efficacy.

Materials and methods

This multi-center cohort study included patients with HCC extrahepatic metastases who received HAIC combined with LEN-P (HAIC-LEN-P group, n=127) or LEN-P alone (n=103) as the primary systemic treatment between January 2019 and December 2022. Baseline data were balanced using a one-to-one propensity score matching (PSM) and inverse probability of treatment weighting (IPTW).

Results

After PSM, the HAIC-LEN-P group significantly extended the median overall survival (mOS) and median progression-free survival (mPFS), compared with the LEN-P group (mOS: 27.0 months vs. 9.0 months, P<0.001; mPFS: 8.0 months vs. 3.0 months, P=0.001). After IPTW, the mOS (hazard ratio (HR)=0.384, P<0.001) and mPFS (HR=0.507, P<0.001) were significantly higher in the HAIC-LEN-P group than in the LEN-P group. The HAIC-LEN-P group's objective response rate was twice as high as that of the LEN-P group (PSM cohort: 67.3% vs. 29.1%, P<0.001; IPTW cohort: 66.1% vs. 27.8%, P<0.001). Moreover, the HAIC-LEN-P group exhibited no noticeable increase in the percentages of grade 3 and 4 adverse events compared with the LEN-P group (P>0.05).

Conclusion

HAIC can improve the efficacy of LEN-P in patients with HCC extrahepatic metastases and may be an alternative treatment for advanced HCC management.

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.

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:BackgroundIntrahepatic cholangiocarcinoma (iCCA) is a highly aggressive cancer with a dismal prognosis and few effective therapeutic approaches. This study aimed to investigate the efficacy, safety, and predictive biomarkers of hepatic arterial infusion chemotherapy (FOLFOX-HAIC) in combination with lenvatinib and PD-1 inhibitor for patients with advanced iCCA.MethodsLocally advanced or metastatic iCCA patients receiving the triple combination therapy of lenvatinib, PD-1 inhibitor, and FOLFOX-HAIC were included in this retrospective study. Primary endpoint was the progression-free survival, evaluated using the RECIST criterion. The secondary endpoints included overall survival, objective response rate, and safety. Whole exome and RNA sequencing of tumor biopsy tissues were performed for biomarker exploration.ResultsBetween May, 2019 and December 2022, a total of 46 patients were included in this study. The primary endpoint showed a median progression-free survival of 9.40 months (95% CI: 5.28-13.52), with a 6-month progression-free survival rate of 76.1%. The median overall survival was 16.77 months (95% CI, 14.20-19.33), with an objective response rate of 47.8% and disease control rate of 91.3% per RECIST. In addition, 4.3% and 8.7% of patients achieved complete response of all lesions and intrahepatic target lesions per mRECIST, respectively. The most common treatment-related adverse events were neutropenia, thrombocytopenia, elevated aspartate aminotransferase and alanine aminotransferase level. Furthermore, integrated analysis of genetic, transcriptomic, and immunohistochemistry data revealed that pre-existing immunity (high expression level of immune-related signatures and intra-tumoral CD8+ T cell density) in baseline tumor tissues was associated with superior clinical benefits. However, the evaluation of tumor mutation burden did not show potential predictive value in this triple combination.ConclusionFOLFOX-HAIC in combination with lenvatinib and PD-1 inhibitor demonstrated a promising antitumor activity with manageable safety profiles in patients with advanced iCCA. Moreover, our study also revealed new perspectives on potential biomarkers for clinical efficacy.
