PURPOSE: To compare the effectiveness of hepatic arterial infusion chemotherapy (HAIC) plus systemic chemotherapy (SYS) with that of SYS alone in patients with intrahepatic cholangiocarcinoma (ICC) with extrahepatic oligometastasis in terms of overall survival (OS) and mortality related to liver failure.
MATERIALS AND METHODS: Consecutive patients diagnosed with ICC with extrahepatic oligometastasis who received either HAIC plus SYS or SYS alone between January 2019 and January 2021 were included in this retrospective cohort study. Propensity score matching (PSM) analysis was performed to address potential confounding factors. OS, progression-free survival (PFS), and intrahepatic progression-free survival (IPFS) were analyzed. The occurrence of death due to liver failure was also assessed.
RESULTS: The study included a total of 179 patients, with 96 receiving SYS alone and 83 receiving HAIC plus SYS. After PSM, 83 pairs were included for further analysis. The median OS and IPFS were significantly longer in the HAIC plus SYS group compared to the SYS alone group (OS: 15.8 months vs 12.7 months; P = .023; IPFS: 9.7 vs 6.1 months; P < .001). No difference was found in PFS between the 2 groups. The HAIC plus SYS group had a significantly lower rate of mortality due to liver failure compared to the SYS alone group (42% vs 72%; P = .002).
CONCLUSIONS: HAIC plus SYS is a promising treatment approach for patients with ICC and extrahepatic oligometastasis with improved OS, IPFS, and freedom from liver failure mortality compared with SYS alone.
