ZAP-70在慢性淋巴细胞白血病中的表达及意义

慢性淋巴细胞白血病是预后异质性很大的疾病。ZAP-70是一种蛋白酪氨酸激酶，在约50％B-CLL表达，与IgVH基因突变、细胞遗传学改变和CD38有明显相关性，已被作为一项独立预后指标，对临床指导治疗有重要价值。     

ZAP-70用于慢性淋巴细胞白血病标准化检测方法的探讨

慢性淋巴细胞白血病是一种临床预后差异极大的疾病。由于ZAP-70与免疫球蛋白重链可变区(IgVH)基因突变有明显相关性且检测方法相对简单,故ZAP-70成为IgVH基因突变的理想替代指标。近年来,不同的ZAP-70检测方法表现出的差异性限制了ZAP-70在临床上的应用,因此ZAP-70标准化检测方法的研究成为焦点。本文就ZAP-70的生物学特征、临床意义、检测方法进行综述。检测方法主要集中在分析方法和实验技术两方面;分析方法包括百分比法、荧光定量法、参比法,其中重要的一步是设定对照;实验技术包括标本的存储、检测时间、固定方法、抗体和荧光素的选择。虽然大量文献对检测方法的诸多变量研究进行了比较,但ZAP-70标准化检测方法在目前尚未有定论。     

ZAP-70、CD38在慢性淋巴细胞白血病中的表达及意义

目的:检测ZAP-70和CD38在慢性B淋巴细胞白血病(B-CLL)中的表达,探讨其与预后的相关性.方法:采用流式细胞仪检测97例慢性B淋巴细胞白血病患者骨髓中白血病细胞ZAP-70、CD38的表达,结合临床分期、化疗疗效进行分析.结果:(1)B-CLL患者中30.9%ZAP-70、CD38同时阳性,49.5%同时阴性.(2)初诊时处于Binet B+C期的:ZAP-70阴性患者为19.0%,ZAP-70阳性患者为75.0%;CD38阴性患者为30.6%,CD38阳性患者为56.8%.ZAP-70、CD38阳性、阴性表达在Binet分期上有显著差异(P<0.00).(3)化疗治疗患者中:ZAP-70阴性者化疗有效(CR+PR)率为90.0%,ZAP-70阳性者化疗有效率为51.3%;CD38阴性者化疗有效率为84.6%,CD38阳性者化疗有效率为48.5%.ZAP-70、CD38阳性、阴性表达在治疗疗效上有显著差异(P<0.01).结论:(1)B-CLL患者ZAP-70表达与CD38表达呈正相关.(2)B-CLL患者ZAP-70、CD38阳性、阴性的表达与Binet分期有关.(3)B-CLL患者ZAP-70、CD38阳性者较阴性者的化疗疗效差.采用流式细胞术检测ZAP-70、CD38的表达可以为B-CLL的临床分期和预后判断提供参考.

慢性淋巴细胞白血病的治疗现状

慢性淋巴细胞白血病(CLL)是由于一种淋巴细胞克隆性增殖,逐步积累而浸润骨髓、血液、淋巴结和其它器官,最终导致造血功能衰竭的一种恶性疾病。CLL通常发生干60岁以上的老年人,男性多于女性。无症状患者的预期寿命与一般人群差异不大,但应定期随访。瘤可宁是标准治疗药物,能延缓有症状患者的进展;瘤可宁治疗无效时常使用氟达拉滨单药或联合其它制剂进行治疗;单克隆抗体也是治疗CLL的一种较有希望的药物;此外,同种移植能使部分CLL患者获得治愈。

Bag3基因在慢性淋巴细胞白血病的表达及其与预后关系的研究

本研究旨在探索bag3基因在慢性淋巴细胞白血病(chronic lymphocytic leukemia,CLL)中的表达及与患者预后的关系。通过实时定量PCR技术,采用SYBR Green荧光染料法对46例CLL患者外周血标本bag3 mRNA表达水平进行相对定量检测,并分析CLL患者bag3基因异常表达和临床预后指标的相关性。结果表明,46例CLL患者bag3表达水平中位数为0.021(0.0007-1.124),明显高于正常人群[0.0025(0.0005-0.014)];耐药CLL患者的bag3表达水平明显高于治疗有效患者的bag3表达水平;bag3的表达与性别、年龄、淋巴细胞数、临床分期、IgVH基因突变、染色体异常、CD38、ZAP70无明显相关。结论:bag3基因在CLL中的表达水平明显高于正常人群,可能与白血病细胞耐药相关,而与CLL患者临床分期及临床常规预后因素无明显相关。     

203例慢性淋巴细胞白血病患者预后相关因素分析

Objective To explore prognostic factors in patients with chronic lymphocytic leukemia (CLL). Methods Two hundred and three CLL patients in our hospital between 2000 to 2007 were retro-spectively reviewed for prognostic factor analysis. Survival was analysed by Kaplan-Meier analysis, univariate analysis by Log-rank test and multivariate analysis by COX regression model. Results With a median follow-up time of 48.0 (3.0 - 156.0) months, the 5-year overall survival (OS) rate was (87.3 ± 2.4) % and 10-year OS rate was (77.4 ± 3.3) %. Forty-eight (23.6%) patients died. Univariate analysis indicated that ad-vanced clinical stage, B symptoms, extranodal involvement, number of lymph node regions involved ≥3, en-larged liver, Hb < 100 g/L, BPC < 100 × 109/L, absolute lymphocyte count (ALC) > 50 × 109/L, atypical cell morphology, progression to stage, non-respons to treatment, complicating infections and secondary cancer or disease transformation were associated with poor prognosis. And on multivariate analysis, lymph node re-gion involvod≥3 and atypical cell morphology were independent poor prognostic factors. Based on the two in-dependent poor prognostic factors, three risk groups were defined: low- (0 factor), intermediate-(one factor) and high-(two factors) groups. The 5 year OS rates were (89.8 ± 3.5) % , (66.4 ～ 7.2) % and (15.0 ±13.8)%, respectively, and the difference between them was statistically. Conclusion The number of lymph node region involved and cell morphology are useful for assessing CLL patients prognosis.
