双克隆型多发性骨髓瘤五例

 目的　研究双克隆型多发性骨髓瘤（MM）患者的临床特点及治疗。方法　分析该科自1996年1月至2010年6月收治的5例双克隆型MM患者，男性2例，女性3例，年龄59～76岁，中位年龄72岁。其中IgG+IgA型3例，IgM+IgG／A型2例。结果　本组患者中诊断时均为DS分期Ⅲ期，治疗效果为2／4达到部分缓解（PR），1／4为稳定（SD），1／4为进展（PD），无达到完全缓解（CR）的病例。结论　双克隆型MM较为罕见，目前对此型MM的诊断和治疗尚缺乏更深刻的认识，需要更多病例的分析。

Immunophonotype of acute myeloid leukemia and mixed leukemia detected by flow cytometry

Objective To detect by flow cytometry (FCM) acute myeloid leukemia. Methods Fourcolor staining was used for analysis of immunphonotypes of 52 cases with acute myeloid leukemia and 7 cases of mixed leukaemia. Results 52 cases with series of patients with AML expression, with the main expression CD13 (94.2 %), CD117 (90.4 %), cMPO (90.4 %) CD33 (86.5 %), CD34 (57.7 %), HLA-DR (53.8 %). In 7 cases of mixed cell leukemia 3 cases of myeloid/B (M/B), are expressing CD13, CD34, CD117, CD10, CD19, cMPO, cCD79a.Myeloid/T (M/T) 2 cases with expression of CD13, CD117, CD33, CD34, CD5,CD7, cMPO; B department/T (B/T) 2cases, with expression of CD5, CD7, CD10, CD19, CD20, CD34. And with the morphological and organizations with high accuracy of chemical diagnosis. Conclusion FCM can improve the diagnose rate for AML and mixed leukemia. And has played an important clinical significance.
