HAIC versus TACE for patients with unresectable hepatocellular carcinoma: A systematic review and meta-analysis.

Background: Hepatic arterial infusion chemotherapy (HAIC) and Transarterial chemoembolization (TACE) both showed good local efficacy in advanced or unresectable hepatocellular carcinoma (HCC). We performed a systematic review and meta-analysis to compare the effect of HAIC with TACE in patients with unresectable HCC.

Methods: Clinical trials, which were about HAIC or TACE in Patients with unresectable HCC, were identified by searching PubMed, Medline, and EMBASE from January 2010 to March 2022. A meta-analysis was performed to analyze HAIC in comparison with TACE. Treatment response, 1-year overall survival (OS), 2-year OS and serious adverse events were evaluated in this meta-analysis.

Results: This meta-analysis included 6 studies. Objective response rate or Partial response in the HAIC group was significantly more than that in the TACE group (P < .05). But, stable disease showed no difference between the 2 groups (P = .52). Disease control rate in the HAIC group was better than that in the TACE group (P < .05). Progressive disease in the HAIC group was less than that in the TACE group (P < .05). In 1-year OS, there was no significant deterioration between the 2 groups (P = .53). There was not significant difference in 2-year OS between the 2 groups (P = .05). serious adverse events in the HAIC group was significantly less than that in the TACE group (P < .05).

Conclusion: To some degree, HAIC may be a better therapeutic method in patients with unresectable HCC than TACE.
