摘要
目的:探讨慢性粒细胞白血病(CML)患者核型变化的有关特点及预后意义。方法:染色体制备采用骨髓细胞短期培养法,应用R显带技术对64例CML患者的骨髓细胞进行遗传学分析。结果:64例CML患者中,53例检出典型费城染色体(Ph),2例为变异Ph易位,2例Ph阴性,6例核型呈嵌合状态,5例出现附加染色体异常,主要为+8、-17、-y、-21等。其中3例为加速和急变期患者。结论:CML是一种高度异质性疾病,非随机的附加染色体异常与患者临床分期高度相关,CML患者进行染色体分析对于疾病的诊断及鉴别、指导临床治疗、判断预后具有重要意义。
Objective:To explore the characteristic and prognosis of chromosome changes in patients with chronic myeloid leukemia . Methods: The chromosomes were obtained by short culturing of bone marrow cell and analyed under microscope after R - banding. Results: 64 patients with CML, 53 cases were Ph positive, 2 cases were variant Ph translocations, 2 cases were Ph negative , 6 cases were the chimer Ph positive and Ph negative. In 5 cases beside the Ph positive, the additional chromosome abnormality were detected, such as + 8、- 17、 - y、- 21,3 cases were in accelerated and balstic phase. Conclusion: The occurrence of additional chromosome abnormality is highly correlative to the clinical phase of the patients . The chromosome analysis was not only useful to the diagnosis and the differentiate, but also importance for the treatment as well as prognosis.
