INT J LAB HEMATOL:诊断使用ADVIA 2120i Siemens和APL标准可以帮助降低APL的早期死亡率?

急性早幼粒细胞白血病(Acute promyelocytic leukemia, APL)是一种急性髓系白血病(Acute myeloid leukemia, AML),伴有危及生命的凝血功能障碍。一旦疑似,就应该开始ATRA治疗。识别APL的细节是至关重要的,但是目前需要经验丰富的血液病理学家。基于自动血细胞计数器ADVIA 2120i Siemens生成的参数,研究人员开发了一种辅助APL诊

急性早幼粒细胞白血病(Acute promyelocytic leukemia, APL)是一种急性髓系白血病(Acute myeloid leukemia, AML),伴有危及生命的凝血功能障碍。一旦疑似,就应该开始ATRA治疗。识别APL的细节是至关重要的,但是目前需要经验丰富的血液病理学家。基于自动血细胞计数器ADVIA 2120i Siemens生成的参数,研究人员开发了一种辅助APL诊断的算法。

本研究算法中的所有参数都是在APL的病理生理学和分析仪技术的基础上选取的。使用c1截止:PLT < 150×103;% Mono < 10;% LUC < 4;高铬细胞> 2 %;%饱和细胞≥1;%生成> 4。在6次中断中至少满足5次,研究人员获得了一个“APL标准”。它在247.209个常规和紧急样本的原始‐数据和124APL的原始‐数据上进行了测试。研究人员进行了多参数分析并得到了确定的截止时间(c2)。在一组新的常规和应急原始‐数据上进行了验证。最后,对AMLALLMDSMPN、肿瘤样本、溶血性和巨幼细胞性贫血进行了检测。

结果表明,该算法在白细胞数目高或正常的APL中具有较高的敏感性(86.30%)和特异性(99.83%),在细胞减少的APL中具有较好的结果(80%)。在血液病和非血液病组中,特异性也很高。它可以作为一种“APL标准”,提醒病理学家可能存在APL。它与仪器和经典形态学结合,可以减少诊断时间,从而进一步减少早期死亡。
