Abstract
BACKGROUND: Hepatocellular carcinoma (HCC) is the fifth most common cancer worldwide. Due to the advanced stage in which HCC presents, most patients are only eligible for transarterial chemoembolization (TACE) or radioembolization (Y(90)). The purpose of this study is to examine the differences in survival and health-related quality of life (HRQOL) in patients diagnosed with HCC and treated with TACE or Y(90). METHODS: Two hundred thirty-four patients with HCC were enrolled in studies examining HRQOL between 2003-2009. HRQOL was evaluated using the Functional Assessment of Cancer Therapy-Hepatobiliary (FACT-Hep). Between-group differences were examined using chi-square and ANOVA. Survival was assessed using Kaplan-Meier and Cox regression analyses. RESULTS: Significant baseline differences between patients treated with TACE versus Y(90) were found. Patients who received Y(90) tended to be older (p < 0.001), female (p < 0.001), had fewer lesions (p = 0.03), had smaller tumors (p = 0.03), and were less likely to have vascular invasion (p = 0.04). After adjusting for demographic and disease-specific factors, no significant differences in HRQOL were observed at 3 months (p = 0.79) or 6 months (p = 0.75). Clinically meaningful differences were found, with the TACE group reporting greater physical, social, and emotional well-being at 3 and 6 months and greater overall HRQOL at 6 months. No significant differences in survival were found. CONCLUSIONS: Treatment with TACE and Y(90) was similar with regard to survival. However, TACE showed statistically and clinically meaningful benefits in physical, social/family, and emotional well-being. Further research is warranted to identify profiles of patients who may demonstrate a preferential response to either TACE or Y(90).
