In this study, the authors explored the influence of hospital radiofrequency ablation (RFA) volume on the prognosis of patients who received RFA for hepatocellular carcinoma (HCC). METHODS: The authors searched for all patients who were diagnosed with stage I or stage II HCC from 2004 to 2006 and who received RFA as first-line therapy in a population-based cohort. Overall survival (OS) and liver cancer-specific survival (CSS) were compared according to hospital volume. A Cox proportional hazards model was used for multivariate analysis. RESULTS: In total, 661 patients received first-line RFA for stage I and II HCC in 28 hospitals. Among these, there were 480 patients (72.6%) in the high-volume group (those who received RFA at hospitals that treated >10 first-line patients per year), and there were 181 patients (27.4%) in the low-volume group (those who received RFA at hospitals that treated ?10 first-line patients per year). The sex, age, stage, tumor size, and year of diagnosis for patients in the 2 groups did not differ significantly. Patients in the high-volume group demonstrated significantly longer OS and CSS than those in the low-volume group (5-year OS rate, 58.7% vs 47.2%; P =.001; 5-year CSS rate, 67.1% vs 57.1%; P =.009). After adjusting for covariates, high-volume hospitals remained an independent predictor of longer OS (hazard ratio, 0.57; P <.001) and CSS (hazard ratio, 0.57; P =.003). CONCLUSIONS: Patients who received first-line RFA for HCC in high-volume hospitals demonstrated better survival outcomes. Cancer 2013. ? 2012 American Cancer Society. |
