[Clinical efficacy of immunotherapy of dendritic cell and cytokine-induced killer cell combined with chemotherapy for treatment of multiple myeloma].

OBJECTIVE

This research was aimed to evaluate the immune mechanism and clinical effect of immunotherapy of dendritic cells (DC) and cytokine-induced killer cell (CIK) combined with chemotherapy on multiple myeloma (MM).

METHODS

60 patients with MM were randomly divided into two groups. 30 patients in chemotherapy group were treated by chemotherapy only, 30 patients in joint group were treated by adoptive immunotherapy (DC-CIK) combined with chemotherapy. A variety of immunological indexes (Hsp70, Th1/Th2, TGF-β) of all patients before and after chemotherapy were recorded; Also the clinical outcomes between two groups were compared.

RESULTS

After chemotherapy, the immunological indexes of all patients were better than those of before chemotherapy (P < 0.05); After treatment, quality of life, clinical index and survival in joint group were better than in chemotherapy group (P < 0.05).

CONCLUSION

Chemotherapy could break the immunosuppression of MM and improve the anti-tumor response of DC-CIK; Chemotherapy and DC-CIK may have synergistic effect for MM.
