Long-term prognosis of hepatocellular carcinoma patients treated with adoptive immunotherapy

Adoptive immunotherapy was performed for patients with multiple hepatocellular carcinoma (HCC) using LAK cells via the hepatic arterial catheter. One case study: A 45-year-old male patient was performed an absolute-non-cure operation. The operation was a success. However, some residual tumors remained in the liver. After the operation, adoptive immunotherapy was performed for 7 times in 5 weeks. The total inoculated LAK cells were 6.9x10(9). After the adoptive immunotherapy, no residual tumors were detected in the liver. He survived for 7 years in remission. Our results show that adoptive immunotherapy with LAK cells is useful and effective for patients with multiple HCC.
