Abstract
Background:
Transarterial chemoembolisation (TACE) is the primary treatment for intermediate-stage hepatocellular carcinoma (HCC), according to the updated Barcelona Clinic Liver Cancer (BCLC) staging system. Although growing evidence favours liver resection (LR) over TACE for intermediate-stage HCC, the best treatment option remains controversial. This meta-analysis aimed to compare the overall survival (OS) after LR versus TACE for intermediate-stage HCC.
Methods:
A comprehensive literature review of PubMed, Embase, Cochrane Library, and Web of Science was performed. Studies that compared the efficacy of LR and TACE in patients with intermediate (BCLC stage B) HCC were selected. According to the recent updated BCLC classification, intermediate stage of HCC was defined as follows: (a) four or more HCC nodules of any size, or (b) two or three nodules, but if at least one tumour is larger than 3 cm. The main outcome was OS, expressed as the hazard ratio.
Results:
Nine eligible studies of 3355 patients were included in the review. The OS of patients who underwent LR was significantly longer than that of patients who underwent TACE (hazard ratio=0.52; 95% CI: 0.39–0.69; I2=79%). Prolonged survival following LR was confirmed after sensitivity analysis of five studies using propensity score matching (HR=0.45; 95% CI: 0.34–0.59; I
2=55%).
Conclusion:
Patients with intermediate-stage HCC who underwent LR had a longer OS that those who underwent TACE. The role of LR in patients with BCLC stage B should be clarified in future randomised controlled trials.
