However, the efficacy of TACE on large(> 10 cm) stage A-B HCC is far from satisfactory, and it is proposed that hepatic artery infusion chemotherapy(HAIC)might be a better first-line treatment of this disease. Hence, we compared the safety and efficacy of HAIC with the modified FOLFOX(mFOLFOX) regimen and those ofTACE in patients with massive unresectable HCC.Methods: A prospective, non-randomized, phase II study was conducted on patients with massive unresectable HCC. The protocol involved HAIC with the mFOLFOX regimen(oxaliplatin, 85 mg/m^2 intra-arterial infusion; leucovorin,400 mg/m^2 intra-arterial infusion; and fluorouracil, 400 mg/m2 bolus infusion and 2400 mg/m^2 continuous infusion)every 3 weeks and TACE with 50 mg of epirubicin, 50 mg of lobaplatin, 6 mg of mitomycin, and lipiodol and polyvinyl alcohol particles. The tumor responses, time-to-progression(TTP), and safety were assessed.Results: A total of 79 patients were recruited for this study: 38 in the HAIC group and 41 in the TACE group. The HAIC group exhibited higher partial response and disease control rates than did the TACE group(52.6% vs. 9.8%, P < 0.001;83.8% vs. 52.5%, P = 0.004). The median TTPs for the HAIC and TACE groups were 5.87 and 3.6 months(hazard radio[HR] = 2.35,95% confidence interval [CI] = 1.16-4.76, P = 0.015). More patients in the HAIC group than in the TACE group underwent resection(10 vs. 3,P = 0.033). The proportions of grade 3-4 adverse events(AE) and serious adverse events(SAE) were lower in the HAIC group than in the TACE group(grade 3-4 AEs: 13 vs. 27, P = 0.007;SAEs: 6 vs. 15,p = 0.044). More patients in the TACE group than in the HAIC group had the study treatment terminated early due to intolerable treatment-related adverse events or the withdrawal of consent(10 vs. 2,P = 0.026).Conclusions: HAIC with mFOLFOX yielded significantly better treatment responses and less serious toxicity than did TACE. HAIC might represent a feasible and promising first-line treatment for patients with massive unresectable HCC.展开更多
