地西他滨联合不同化疗方案治疗老年人急性髓系白血病的临床观察

目的 观察地西他滨（DAC）联合IA方案（去甲氧柔红霉素＋阿糖胞苷）或CAG方案（阿柔比星＋阿糖胞苷＋粒细胞集落刺激因子）治疗老年人急性髓系白血病（AML）的疗效及不良反应.方法 回顾性分析47例老年AML患者的临床资料,按接受不同化疗方案分为DAC＋ IA组（17例）和DAC＋CAG组（30例）,观察两组的疗效及不良反应.结果 DAC＋IA组获完全缓解（CR）5例（29.4％）,部分缓解（PR）6例（35.3％）,总有效率为64.7％（11/17）;DAC＋CAG组获CR 8例（26.7％）,PR 9例（30.0％）,总有效率为56.7％（17/30）;两组有效率比较差异无统计学意义（x 2=0.227,P=0.716）.DAC＋IA组中位缓解时间、中位生存期分别为4.0、8.1个月,DAC＋CAG组中位缓解时间、中位生存期分别为3.7、9.5个月,两组间差异均无统计学意义（P值分别为0.104、0.525）.结论 DAC＋IA方案治疗老年AML患者疗效与DAC＋CAG方案接近,同时并未增加相关不良反应,可作为老年人AML的一线治疗方案.

Clinical analysis of decitabine combine with different regimens in the treatment of elderly patients with acute myeloid leukemia

Objective To investigate the therapeutic effects and adverse reactions of decitabine combined with IA or CAG regimen in the treatment of elderly patients with acute myeloid leukemia.Methods A retrospective analysis was made to observe the therapeutic effects and adverse reactions of 47 elderly patients with acute myeloid leukemia,who were divided into DAC＋IA group （17 cases） and DAC＋CAG group （28 cases） according to the different chemotherapy.Results In DAC＋IA group,the rate of complete remission was 29.4 % （5/17）,the rate of partial remission was 35.3 % （6/17）,the effective rate was 64.7 % （11/17）.In DAC＋CAG group,the rate of complete remission was 26.7 % （8/30）,the rate of partial remission was 30.0 % （9/30）,the effective rate was 56.7 % （17/30）,the difference between the two groups was not statistically significant （x2 =0.227,P =0.716）.In DAC＋IA group the median remission time and the median suvival time were 4.0 and 8.1 months,respectively.And they were 4.0 and 8.1 months,respectively,in DAC＋CAG group.No significant difference was showed between the two groups （P value was 0.835,0.266,respectively）.Conclusions Compared with decitabine combined with CAG regimen,decitabine combined with IA regimen has similar effect and can be well tolerated.Accordingly,decitabine combined with IA regimen can be used as first-line treatment for elderly patients with acute myeloid leukemia.
