摘要:

急性早期前体T淋巴细胞白血病(ETP-ALL)患者过氧化物酶(POX)阳性率>3%是一种较为罕见的现象。文章对上海交通大学医学院附属第一人民医院收治的1例POX阳性率>3%的ETP-ALL病例的骨髓细胞形态(骨髓细胞形态结果提示混合表型急性白血病)、流式细胞免疫分型(ETP-ALL免疫表型)、基因突变(FBXW7 6.76%突变、IKZF1 7.53%突变、NOTCH1 8.12%突变、NRAS 8.26%突变、TCRβDβ-克隆性基因重排)、染色体核型(46,XY,del(2)(p24),t(3;5)(q11;q11)/46,XY[17])等临床特征进行综合分析,以提高临床对此类疾病的认识。

Abstract:

Early T-cell precursor acute lymphoblastic leukemia (ETP-ALL) with peroxidase(POX) positive rate>3% is rarely seen. The determination results of ETP-ALL with POX positive rate>3% from a case of Shanghai General Hospital of Shanghai Jiao Tong University School of Medicine were analyzed. The morphological result shows this may be mixed phenotype acute leukemia;the result of flow cytometry indicates ETP-ALL;next generation sequencing results show mutation of FBXW7(6.76%),IKZF1(7.53%),NOTCH1(8.12%),NRAS (8.26%),TCRβDβ-Jβ rearrangements;the analysis of chromosome karyotype is 46,XY,del(2)(p24),t(3;5)(q11;q11)/46,XY[17]. This study aims to improve the diagnostic and therapeutic ability of this disease.

Key words: Peroxidase, Early T-cell precursor acute lymphoblastic leukemia, Early T-cell precursor lymphocyte, Mixed phenotype leukemia, Peroxidase positive rate
