Transcatheter hepatic arterial chemoembolization and sorafenib for hepatocellular carcinoma: a meta-analysis of randomized, double-blind controlled trials.

ABSTRACT: We performed a meta-analysis of transcatheter hepatic arterial chemoembolization (TACE) combined with sorafenib for hepatocellular carcinoma (HCC), which included 4 double-blind, randomized controlled trials (RCTs) that investigated the effects of TACE combined with sorafenib (experimental groups) on time to disease progression (TTP), overall survival (OS), and various sorafenib-related adverse events, compared to those in the placebo (control) groups. A total of 877 HCC cases from 14 countries, including China and the USA, were included in our meta-analysis. The TTP increased significantly in the experimental groups (hazard ration [HR]: 0.82; 95% CI: 0.69-0.97; p = 0.02), but OS did not improve significantly (HR: 0.97; 95% CI: 0.72-1.29; p = 0.82), compared with the control groups. The risks of hand and foot skin reactions (HFSR), rash, fatigue, and diarrhea were significantly greater in the experimental groups (p < 0.05 for all), compared to those in the control groups, whereas the risk of nausea was statistically similar (p > 0.05). Among these, the risk of HFSR was highest (risk ratio [RR]: 5.93; 95% CI: 2.00-17.53; p = 0.001), and a subgroup analysis of studies that lacked significant heterogeneity in the HFSR data showed a higher risk of HFSR (RR: 10.96; 95% CI: 5.54-21.69; p < 0.05). In conclusion, although TACE plus sorafenib increases TTP, it does not improve OS. Therefore, the risk of the adverse events of TACE plus sorafenib should be considered as a potential therapeutic limitation.

Project description:Targeted therapy is currently the standard treatment for advanced hepatocellular carcinoma (HCC), but an effective treatment after the discontinuation of sorafenib therapy remains uncertain. We aim to investigate the survival benefits of transcatheter arterial chemoembolization (TACE) after stopping sorafenib therapy. We retrospectively analyzed all patients with advanced HCC, who had received palliative TACE after terminating sorafenib therapy, from January 2008 to June 2016. Patients who were in the terminal stage (Child-Pugh class C or performance status 3-4), who received a liver transplantation, or who had received any HCC treatment other than TACE, were excluded. Finally, 28 patients were recruited as the TACE group, and were randomly matched 1:1 by age, gender, Child-Pugh class, extrahepatic metastasis, and portal vein thrombosis with 28 controls who only received supportive care. For avoiding any immortal time bias, the index date of outcome follow-up was also matched. Cumulative incidences of, and hazard ratios (HRs) for, patient mortality were analyzed. The baseline demographic data between the TACE group and the control group were similar, but the 1-year overall survival rate in the TACE group was significantly higher than that of the control group (41.2%, 95% confidence interval [CI]: 19.4-63.0% vs. 24.5%, 95% CI: 6.3-42.7%; p < 0.01). In multivariate analysis, after adjusting for alpha-fetoprotein > 400ng/mL, Child-Pugh class B, and tumor extension > 50% of liver volume, TACE was independently associated with a decreased mortality risk(HR 0.19, 95% CI: 0.08-0.42). In addition, tumor extension > 50% of the liver was another independent prognostic factor associated with an increased mortality risk (HR 2.99, 95% CI: 1.31-6.82). Multivariate stratified analyses verified the association of TACE with a decreased mortality rate in each patient subgroup (all HR < 1.0). By controlling intrahepatic tumor growth, TACE may be a treatment option for use in improving patient survival in advanced HCC, after the termination of sorafenib therapy.

Project description:Purpose:Sorafenib is recommended for patients with hepatocellular carcinoma refractory to transarterial chemoembolization but with unsatisfactory overall survival and tumor response rate. Previously published studies showed hepatic arterial infusion chemotherapy of oxaliplatin, fluorouracil, and leucovorin was an effective and safe treatment. The aims of this study were to compare the clinical efficacy and safety of oxaliplatin, fluorouracil, and leucovorin-based hepatic arterial infusion chemotherapy with sorafenib in patients with hepatocellular carcinoma refractory to transarterial chemoembolization. Methods: This was a retrospective subgroup analysis of 2 prospective clinical trials, including 114 patients with hepatocellular carcinoma who were confirmed to be transarterial chemoembolization refractoriness. Of these, 55 patients received hepatic arterial infusion chemotherapy of fluorouracil, and leucovorin (FOLFOX-HAIC group, oxaliplatin 85 or 130 mg/m2, leucovorin 400 mg/m2, fluorouracil bolus 400 mg/m2, and 2400 mg/m2 for 23 or 46 h, every 3 weeks), and 59 patients were treated with sorafenib (sorafenib group, 400 mg sorafenib twice daily). Overall survival, progression-free survival, objective response rate, and treatment-related adverse events were compared between the 2 groups. Results: The FOLFOX-HAIC group showed a longer overall survival (17.1 months [95% confidence interval 13.4-20.8] vs 9.1 months [95% confidence interval 7.5-10.6]; hazard ratio 0.35 [95% confidence interval 0.23-0.53]; P < .001), a higher objective response rate (RECIST: 18 [32.7%] vs 1 [1.7%], P < .001), and a longer progression-free survival (7.6 months [95% confidence interval 5.6-9.6] vs 3.9 months [95% confidence interval 2.3-5.4]; hazard ratio 0.49 [95% confidence interval 0.33-0.72]; P < .001) than the sorafenib group. The safety results suggested that both oxaliplatin, fluorouracil, and leucovorin-based hepatic arterial infusion chemotherapy and sorafenib had acceptable treatment-related toxic effects. No significant difference was observed in the overall occurrence of any grade, grade 3/4, or serious adverse events between the 2 groups. Conclusions: Oxaliplatin, fluorouracil, and leucovorin-based hepatic arterial infusion chemotherapy might be a better choice than sorafenib for patients with hepatocellular carcinoma refractory to transarterial chemoembolization.

Project description:PurposeTo validate the therapeutic efficacy of sorafenib-eluting embolic microspheres (SOR-EMs) used in combination with transarterial chemoembolization (TACE) for treatment of hepatocellular carcinoma (HCC) in a preclinical animal model.Materials and methodsSOR-EMs were prepared with poly(d,l-lactide-co-glycolide), iron oxide nanoparticles, and sorafenib. The morphology of the prepared SOR-EMs was confirmed by using optical microscopy. Drug release from the SOR-EMs was quantified in vitro by using high-performance liquid chromatography. In an orthotopic rat model of HCC, embolic doxorubicin-Lipiodol (ethiodized oil) emulsion (DLE) and SOR-EMs were sequentially injected into the hepatic artery of the rats: The rats in group 1 were injected with DLE; group 2 was injected with DLE plus unloaded embolic microspheres (DLE + EM); group 3, with DLE plus SOR-EMs (DLE + SOR-EM); and group 4, with saline solution. The SOR-EM and tumor size changes in each group (of six rats each) over time were measured by using MRI. Tissues were assessed by using immunohistochemistry, with hematoxylin-eosin and terminal deoxynucleotidyl transferase-mediated dUTP (2'-deoxyuridine 5'-triphosphate) nick-end labeling staining used for dead cells and CD34 staining used for new microvessel formation.ResultsThe SOR-EMs were a mean size of 6.6 μm ± 2.3 (standard deviation) and showed 53.7% ± 8.3 sorafenib loading efficiency with T2-weighted MRI capability. In the HCC rat model, the intra-arterially injected SOR-EMs were successfully monitored by using MRI. The DLE + SOR-EM-treated rats showed a superior tumor growth-inhibitory effect compared with the rats treated with DLE only (P < .05). Immunohistochemical assessment of tissue specimens showed that compared with the other treatment groups, the DLE + SOR-EM treatment group had the lowest number of microvessels, as quantified by using the percentage of CD34-positive stained area (P < .01 for all comparisons).ConclusionIn a preclinical rat HCC model, SOR-EMs used in combination with DLE TACE were effective in treating HCC.Keywords: Chemoembolization, Experimental Investigations, Laboratory Tests, Liver, Technology Assessment Supplemental material is available for this article. © RSNA, 2021See also the commentary by Yamada and Gayed in this issue.
