Hepatic Arterial Infusion Chemotherapy with Cisplatin for TACE-Refractory or -Ineligible Hepatocellular Carcinoma with Child-Pugh Score of 8 or Above

Background This study aimed to retrospectively assess the safety and usefulness of hepatic arterial infusion chemotherapy (HAIC) with cisplatin in patients with hepatocellular carcinoma (HCC) and Child-Pugh (C-P) score ≥ 8, who were refractory to or ineligible for transcatheter arterial chemoembolization (TACE). Methods In this study, 28 cisplatin-naïve patients with HCC, C-P score ≥ 8, and no evidence of extrahepatic lesions were treated using HAIC with cisplatin between July 2004 and July 2013. Results Of 28 patients, 10 were refractory to TACE and 18 ineligible for TACE. In terms of C-P score, 17 patients had a score of 8, 6 a score of 9, and 5 a score of 10. The injected dose of cisplatin was reduced in 64.3% of cases. The overall response rate was 10.7%, with a disease control rate of 35.7%. Overall, median survival time (MST) and progression-free survival were 186 and 80 days, respectively. In patients with macroscopic vascular invasion (MVI-positive; n = 9), these values decreased to 161 and 72 days, respectively; while they increased to 341 and 87 days, respectively, in MVI-negative patients (n = 19). Patients achieving partial response (PR) and stable disease (SD) status as well as those achieving SD status showed significantly better survival than patients with progressive disease (PD status): PR + SD vs. PD: MST = 447 vs. 123 days, P < 0.001; SD vs. PD: MST = 447 vs. 123 days, P = 0.001). No serious adverse event or treatment-related death occurred. Conclusions HAIC with cisplatin can be safely administered in patients with HCC and C-P score ≥ 8, who are TACE-refractory or -ineligible. An extended survival time is expected when the treatment outcome is either SD or more favorable.
