Methods： Isolated peripheral blood mononuclear cells （PBMCs） from 110 advanced solid tumor patients. Added granulocyte-macrophage colony-stimulating factor （GM-CSF）, tumor necrosis factor-a （TNF-a） and interleukin-4 （IL-4） to adherent cells to induce DCs, and sensitized DCs with antigens of autologous tumor cells or extrinsic tumor cell lines. Cultured suspending cells with interferon-y （IFN-y）, interleukin-2 （IL-2） and CD3 monoclonal antibody （CD3 McAb） to prepare CIK cells, then co-cultured with DCs. After analyzing the phenotype and checking tumor markers and immune function, the autologous CIK cells and DCs were transfused into the cancer patients. Results： Forty-two patients with measurable nidus, 2 achieved complete remission （CR）, 9 partial remission （PR） and 15 stable disease （SD）, while 37 patients with immeasurable nidus, 25 had efficient response. The tumor markers and immune function both improved significantly compared with those before treatment. Conclusion： DCs and CIK cells combinational treatment is safe and effective on advanced solid carcinoma and provide a new and efficacious immunity therapeutic methods for the cancer patients.展开更多
