Abstract:

Objective

To assess the effect of transarterial radioembolization (TARE) using Yttrium-90 microsphere for unresectable primary liver cancer (PLC).

Methods

Literature from January 2009 to December 2013 were searched in the Medline, Web of Science, Cochrane Controlled Trial Register (CENTRAL) and EMBASE databases with the search terms mainly including: radioembolization, transarterial radioembolization, TARE, selective internal radiation therapy, SIRT, Yttrium-90, 90Y, chemoembolization, transarterial chemoembolization (TACE), hepatocellular carcinoma, HCC, liver cancer, liver tumor, liver neoplasm and with the assistance of manual searching. Data of the included literature were merged and the patients were divided into TARE group and TACE group according to the different treatments. The data of tumor therapeutic response and 1-, 2-, 3-year survival rates were collected. Literature heterogeneity inspection was conducted by Q test. Publication bias was tested by drawing funnel plot and linear regression model.

Results

Five articles were included after screening with the quality of medium to high. There were totally 591 cases with 292 in TARE group and 299 in TACE group. Meta-analysis was conducted using fixed effect model. Tumor therapeutic response was observed better in TARE group, compared with that in TACE group (RR=1.50, P<0.05). The 2-, 3-year survival rates in TARE group were significantly higher than those in TACE group (RR=1.56, 2.04; P<0.05).

Conclusions

Compared with TACE, TARE can obviously improve the tumor therapeutic response rate and long-term survival rate of patients with unresectable PLC.
