Multiple Antigen Specific Cell Therapy (MASCT) for Hepatocellular Carcinoma(HCC) Patients After Radical Resection or Radio Frequency Ablation(RFA).

Randomized, Open-label, Multi-center Clinical Trial to Compare the Efficacy and Safety of MASCT Group' and 'Non-treatment Group' in Patient Undergone Curative Resection( RFA or Operation) for Hepatocellular Carcinoma .MASCT That Expresses Multiple Antigens Specific Cellular Therapy,Autologous Immune Cytotoxic of T-lymphocytes(CTL) Induced by Dendritic Cell(DC) Loaded With Multiple Antigens

To prove that the efficacy and safety of 'MASCT group' is superior to 'non-treatment group' in patient undergone curative resection (RFA or operation) for hepatocellular carcinoma in China.
