Abstract
Background
To determine the effect of Yttrium-90 (Y90) radioembolization on health-related quality of life (HRQOL) and its effect on overall survival advanced, unresectable infiltrative hepatocellular carcinoma (HCC) patients with concurrent portal vein thrombosis (PVT).
Methods
Consecutive patients with unresectable infiltrative HCC and PVT were recruited. The Short-Form 36 (SF-36) questionnaire was used to assess HRQOL for consecutive patients treated with glass-based Y90 based on a prospective phase II trial. MR imaging was used to determine tumor progression every 3 months post-treatment. Overall survival (OS) from treatment and time to progression (TTP) was analyzed using Kaplan-Meier estimation and log-rank test.
Results
Thirty patients were treated and followed for 17.4 months; physical and mental component summary scores (PCS & MCS) remained unchanged at one, three, and six months. While no difference was observed in baseline SF-36 scores for patients with prolonged TTP (≥4 months) and OS (≥ 6 months), corresponding 1-month PCS were significantly higher than those with TTP < 4 months and OS < 6 months. At 1 month, patients with normalized Physical Function (PF), Role Physical (RP) and PCS within 2 standard deviations (SD) of US normalized baseline scores had a significantly prolonged median OS (15.7 vs. 3.7 months; p < 0.001) and TTP (12.4 vs. 1.8 mo; p < 0.001) compared those with physical component scores greater than 2SD below normalized US population values.
Conclusion
Y90 radioembolization for HCC demonstrated long-term preservation of HRQOL. Lower baseline HRQOL scores were predictive of poorer OS. Early (1 month post-treatment) significant decreases in PCS were independent predictors of poorer OS and TTP.
