Objective:The objectives of this study were to evaluate the long-term results with multimodality therapy, and to clarify the clinicopathologic of features of patients surviving ≥ 3 years for unresectable hepatocellular carcinoma(HCC).Methods:Between 1999 and 2003, a total of 166 patients underwent multimodality therapy for unresectable HCC.All patients underwent multimodality therapy, such as transarterial chemoembolization(TACE), chemotherapy, local ablative therapy, and/ or Chinese traditional medicine.Thirty-nine(23.5%) patients survival ≥ 1 years, and 10(6.0%) patients survived ≥ 3 years.These 39 patients surviving over 1 year were investigated in this study.Eighteen clinical and biologic variables were assessed using univariate and multivariate analyses.Results:TNM staging and tumor extension were isolated by univariate analysis.Only tumor extension was independent risk factors by multiple regression analysis.Of these, 25.6%(10 of 39) survived over 3 years.These 10 patients surviving over 3 years were investigated further.By the end of June 2004, follow-up varied from 3 years and 2 months to 5 years and 1 month.Six patients were still alive with free of disease.Conclusion:Tumor extension was demonstrated to be prognostic of long-term survivors.Multimodality therapy may make a major contribution to achieving long-term survival in patients with unresectable HCC.
