Abstract

AIM: To evaluate the prognostic factors and efficacy of hepatic arterial infusion chemotherapy in hepatocellular carcinoma with portal vein tumor thrombosis.

METHODS: Fifty hepatocellular carcinoma (HCC) patients with portal vein tumor thrombosis (PVTT) were treated using hepatic arterial infusion chemotherapy (HAIC) via a subcutaneously implanted port. The epirubicin-cisplatin-5-fluorouracil (ECF) chemotherapeutic regimen consisted of 35 mg/m2 epirubicin on day 1, 60 mg/m2 cisplatin for 2 h on day 2, and 500 mg/m2 5-fluorouracil for 5 h on days 1-3. The treatments were repeated every 3 or 4 wk.

RESULTS: Three (6%) of the 50 patients achieved a complete response (CR), 13 (26%) showed partial responses (PR), and 22 (44%) had stable disease (SD). The median survival and time to progression were 7 and 2 mo, respectively. After 2 cycles of HAIC, CR was achieved in 1 patient (2%), PR in 10 patients (20%) and SD in 26 patients (52%). Significant pre-treatment prognostic factors were a tumor volume of < 400 cm3 (P = 0.01) and normal levels of protein induced by vitamin K absence or antagonist (PIVKA)-II (P = 0.022). After 2 cycles of treatment, disease control (CR + PR + SD) (P = 0.001), PVTT response (P = 0.003) and α-fetoprotein reduction of over 50% (P = 0.02) were independent factors for survival. Objective response (CR + PR), disease control, PVTT response, and combination therapy during the HAIC were also significant prognostic factors. Adverse events were tolerable and successfully managed.

CONCLUSION: HAIC may be an effective treatment modality for advanced HCC with PVTT in patients with tumors < 400 cm3 and good prognostic factors.

Core tip: The aim of this study was to investigate the prognostic factors of hepatic arterial infusion chemotherapy in advanced hepatocellular carcinoma patients with portal vein tumor thrombosis. The primary findings of this study were as follows: (1) The median survival and time to progression were 7 and 2 mo, respectively; (2) A tumor volume of < 400 cm3 and protein induced by vitamin K absence or antagonist-II were independent pre-treatment prognostic factors; (3) Disease control and ≥ 50% tumor marker reduction were significant prognostic factors after the second cycle of hepatic arterial infusion chemotherapy (HAIC); and (4) Objective tumor response, disease control and portal vein tumor thrombosis response were independent post-treatment prognostic factors at the end of the HAIC.
