摘要 目的进一步认识慢性粒一单核细胞白血病(CMML)细胞形态学和染色体核型特征。方法回顾分析35例CMML患者的血象、骨髓象、细胞化学铁染色,18例染色体核型分析。结果35例患者外周血白细胞(WBC)〉10.0×10^9/L27例(87.3%),血红蛋白(Hb)浓度减低33例(94.3%),血小板(P1t)〈100×10^/L23例(65.7%)。成熟单核细胞绝对值在(1.18。44.2)×10^/L范围内。易见幼稚粒细胞者33例(94.3%),可见幼稚单核细胞者9例(25.7%)。骨髓增生极度活跃或明显活跃28例(80%)。分类中粒系+单核系≥0.70者20例(57.1%),可见幼稚单核细胞24例(68.6%)。表现为一系或两系以上病态造血26例(74.3%)。18例患者染色体核型分析,染色体异常5例(14.3%)。结论该组CMML的患者,血象以WBC增高、Hb和Ph同时减低明显增多为特点。易见幼稚粒细胞,单核细胞绝对值明显增高。骨髓增生异常综合征(MDS)伴单核细胞增多(MDS—CMML)的患者明显比具有骨髓增殖性疾病特征(MPD—CMML)的患者多见。CMML的患者染色体有核型异常,但无特异性,Ph染色体阴性。
