Efficacy of Autologous DC-CIK Cells Combined with Other Immune Cells in the Treatment of Hematological Malignancies -Retrospective Study / 中国实验血液学杂志

ABSTRACT

OBJECTIVE@#To investigate the safety and clinical efficacy of autologous DC-CIK cells combined with other immune cells for patients with hematological malignancies and analyze patient prognosis.@*METHODS@#50 patients with hematological malignancies who received cellular immunotherapy from September 2014 to April 2016 were retrospectively studied in the First Affiliated Hospital of Xi'an Jiaotong University, 115 cases times of cellular immunotherapy were performed. According to the selected treatment, the patients were divided into the dual cell group (DC-CIK cell treatment) and the multi-cell group (DC-CIK cell combined with other immune cells); According to the treatment course, the patients were divided into the single course group (completed by ＜3 times) and the multiple course group. The changes of T lymphocyte subsets, blood routine indicators and KPS scores as well as the overall survival time before and after treatment were compared and analyzed.@*RESULTS@#[WTB1]The difference of general conditions before treatment including the number of patients, sex, age, T lymphocyte subsets, blood routine indicators, KPS scores and so on in 2 groups divided according to 2 kinds of treatment methods were not statistically significant, indicating that the 2 groups were comparable. Grouped by selected treatment, the CD4/CD8 ratio, Hb and Plt levels decreased in the dual cell group, compared with those before treatment(P＜0.05). The CD3CD4 ratio after treatment in multiple cell group decreased, compared with that before treatment (P＜0.05). The 3-year survival rate of patients in dual cell and multiple cell groups was 61.3% vs 69.8%, the overall survival time of patients in 2 groups was 32.4 months vs 39.6 months, there were no statisticall differences between 2 groups(P>0.05). Grouped by treatment course, the CD3 ratio after treatment increased, while the Hb level after treatment decreased in single course group, compared with level before treatment(P＜0.05). The CD3CD4 ratio, Plt level decreased, while the KPS scores increased after treatment in multiple course group, compared with those before treatment(P＜0.05). The 3-year survival rate in single course and multiple course groups was 52% vs 76.4%, the overall survival time was 28.7 months vs 40.9 months respectively, statistically significant with difference (P＜0.05).@*CONCLUSION@#Autologous DC-CIK cells combined with other immune cells in the treatment of hematological malignancies can change the immune function of the patients and improve the antitumor activity. The multi-course treatment can improve the quality of life, prolong the overall survival time, thus worthing clinical promotion.
