尽管目前白血病的诊治水平已显著提高,但复发仍不可避免。近10年来研究认为,患者体内微小残留病(MRD)与白血病复发密切相关。传统形态学检测由于敏感度较低限制了其在MRD检测中的应用。随着分子检测手段的不断改进,尤其是近年来实时定量RTPCR的出现为MRD检测提供了准确、敏感、快速的手段。大量临床研究已证实,MRD的有无及其高低不但反映了个体对治疗的反应情况,而且与预后非常相关,其在白血病早期复发的预示中有显著作用。MRD检测还能用于评价不同治疗方案的疗效,为寻找最佳治疗手段提供了依据。本文对MRD检测方法及其临床应用做一综述,相信随着标准化MRD检测体系的建立必将对白血病复发的预防起重要作用。
