[Efficacy, Prognosis and Safety of Decitabine Combined with Low-Dose Cytarabine in the Treatment of Elderly Patients with Relapsed/Refractory Acute Myeloid Leukemia].

题目: 地西他滨联合低剂量阿糖胞苷治疗老年复发/难治性急性髓系白血病患者的疗效、预后及安全性分析. 目的: 探讨地西他滨联合低剂量CAG化疗方案治疗老年复发/难治性急性髓系白血病（acute myeloid leukemia，AML）患者的疗效、预后及安全性. RESULTS: In combination therapy group the CR was 55.00% （11/20）, OR was 85.00% （17/20）, but in the CAG group CR was 30.00% （6/20）, and OR was 50.00% （10/20）. Till to February 2018, out of 40 patients 17 survived, 20 died, and 3 failed to be followed-up. The median follow-up time was 12 （2 to 35） months; the median survival time in the comtination therapy group was 13 （2-35） months, and the 1-year OS rate was 70.00%, and the median survival time of the CAG group was 10 （2-31） months, and the 1-year OS rate was 50.00%, without staistical significance between the 2 groups （P>0.05）. After treatment, the WBC and Plt counts in the combination therapy group were higher than those in the CAG group, but the Hb level was lower than that in the CAG group with statistically significant difference （P<0.05）. In the combination therapy group, the incidence of lung infection, nausea and vomiting was higher than that of the CAG group （65.00% vs 25.00%, 50.00% vs 20.00%）, with statistically significant difference （P<0.05）. CONCLUSION: Decitabine combined with low-dose CAG regimen is effective for the treatment of relapsed/refractory AML in the elderly. Compared with the standard CAG regimen, the long-term efficacy of this regimen is not different significantly, but its adverse reactions are increase, thus the preventive treatment should be given in time. 结论: 地西他滨联合低剂量CAG方案治疗老年复发/难治性AML近期疗效显著，远期疗效并无差异，但不良反应增加，在临床在治疗过程中要及时给予预防性处理.
