Abstract:

BACKGROUND: Cytokine induced killer cells therapy as an effective means of adoptive immunotherapy, becomes a new way to treat acute myeloid leukemia. But, the researches about sequential cytokine induced killer cells therapy after autologous peripheral blood stem cell transplantation in acute myeloid leukemia patients are still less, which deserve further research.
OBJECTIVE: To observe the clinical efficiency and safety of sequential cytokine induced killer cells therapy after autologous peripheral blood stem cell transplantation in acute myeloid leukemia M2 patients.
METHODS: Totally 45 patients with low- or intermediate-risk acute myeloid leukemia M2 were recruited in this study. Among them, 19 patients received sequential cytokine induced killer cells therapy after autologous peripheral blood stem cell transplantation and 26 patients only received autologous peripheral blood stem cell transplantation. The relapse rate, disease-free survival, and overall survival were compared between two groups, and safety of cytokine induced killer cells therapy was observed.
RESULTS AND CONCLUSION: (1) Compared with the patients only receiving autologous peripheral blood stem cell transplantation, the relapse rate was lower (21.05% vs. 38.46%; P < 0.05), and elevated percentages of the disease-free survival and overall survival were observed in the patients receiving sequential cytokine induced killer cells therapy after autologous peripheral blood stem cell transplantation (P < 0.05). (2) The 19 patients who received sequential cytokine induced killer cells therapy after autologous peripheral blood stem cell transplantation all completed the treatment scheme successfully. Only four patients appeared to have chills and fever, and no more side effects were observed. These findings suggested that the sequential cytokine induced killer cells therapy after autologous peripheral blood stem cell transplantation can improve the disease-free survival and overall survival of low- or intermediate-risk acute myeloid leukemia M2 patients without remarkable side effects, which is a safe, effective and feasible way for the treatment of acute myeloid leukemia M2.
