摘要 目的观察慢性粒单核细胞白血病(CMML)临床特征,探讨地西他滨治疗效果。方法记录统计20例CMML患者血常规三系数值和骨髓情况并分析总结临床疗效。结果20例CMML患者血红蛋白52~140(87.01±17.30)g/L,贫血16例,白细胞平均(19.2±2.09)×10^9/L。其中白细胞小于4×10^9/L 1例(5.00%),(4-10)×10^9/L 7例(35.00%),大于10×10^9/L 12例(60.00%)。单核细胞中位数(1.5~46.28)×10^9/L,平均(2.78±1.67)×10^9/L。20例患者中脾肿大12例(60.00%),肝功能异常1例(5.00%),外周血未出现原始细胞。骨髓象结果:原始细胞(9.02±1.78)%。骨髓增生明显活跃9例,极度活跃6例,活跃3例。骨髓活检Gomori+18例(90.00%),Gomori++2例(10.00%)。20例患者中染色体异常1例(5.00%),为+8,染色体正常19例(95.00%)。进行二代测序4例,TET2基因突变2例;20例患者JAK2(V617F)及BCR-ABL基因正常。地西他滨治疗4个周期后,总反应率为55.00%;随访生存时间1~42个月,平均(20.28±7.34)个月。结论CMML多为高龄,男性比例高,染色体异常少见,地西他滨可明显延长CMML生存时间,相对传统非地西他滨治疗可以获得较高完全缓解及骨髓完全缓解。
