Abstract
323 Background: Transarterial Radio-embolization (TARE) has emerged as a newer regional technique to Transarterial Chemo-embolization (TACE) for treatment of unresectable hepatocellular carcinoma (HCC). The aim of this study is to evaluate clinical outcomes of both techniques. Methods: Online search for studies comparing TARE to TACE from 2005 to present was performed. Primary outcome was overall survival rate for up to 4 years. Secondary outcomes included post-treatment complications and treatment response. Quality of included studies was evaluated by STROBE criteria. Relative Risk (RR) and 95% Confidence Intervals (CI) were calculated from pooled data. Results: The search strategy yielded 172 studies, 5 met our selection criteria and included 653 patients undergoing embolization for unresectable HCC. Of these patients, 284 underwent TACE and 269 underwent TARE. Median age was 63 and 64 years for TACE and TARE, respectively. Meta-analysis showed no statistically significant difference in survival for up to 4 years between the two groups (HR = 1.06; 95% CI: 0.81-1.46, p = 0.567). TACE required at least one day of hospital stay compared to TARE which was mostly an outpatient procedure. TACE had more post-treatment pain than TARE (RR = 1.96, 95% CI: 1.40-2.75, p < 0.01), but less subjective fatigue (RR = 0.62, 95% CI: 0.48-0.80, p < 0.01). There was no difference between the two groups in the incidence of post-treatment nausea, vomiting, fever or other complications. In addition, there was no difference in partial or complete response rates between the two groups. Conclusions: TARE appears to be a safe alternative treatment to TACE with similar complication profile and survival rates. Larger prospective randomized trials, focusing on patient-reported quality-of-life are required to consolidate these results, and to evaluate cost vs benefit for both techniques.
