Abstract:
OBJECTIVES:To examine the efficacy and prognostic benefits of radiotherapy (RT) in patients who have unresectable advanced hepatocellular carcinoma (HCC) with invasion to intrahepatic large vessels (IHLVs). METHODS:Sixty-eight patients who had advanced HCC with invasion to IHLVs were studied. Thirty-two consecutive patients initially received 3-dimensional conformal RT for HCC invasion to IHLVs. Tumor response, prognostic factors, and survival were studied in the patients given RT. Prognostic factors and survival were assessed in the study group as a whole. Data were analyzed using the Kaplan-Meier method, univariate analysis, and a Cox model. RESULTS:The rate of objective response to RT was 48%. Predictors of survival in the patients who received RT were a hepatic function of Child-Pugh class A (p = 0.0263) and a response to RT (p = 0.0121). In the study group as a whole, independent predictors of survival in a Cox model were multinodular HCC (p = 0.007), inferior vena caval invasion (p = 0.001), a serum alpha-fetoprotein level of >1,000 ng/ml (p = 0.032), and the performance of RT (p < 0.001). Notably, the median survival of the nonresponders to RT (n = 15) was significantly longer than that of the patients who received no treatment for HCC (n = 21; 7.0 vs. 3.4 months, p = 0.0014). CONCLUSION:RT is considered an effective initial treatment for HCC invasion to IHLVs, and may offer survival benefits, even in nonresponders, because of the induction of stable disease.
