摘要:

目的 探讨近四倍体急性淋巴细胞白血病(NT-ALL)的临床表现、形态学改变及其预后。方法 分析1例NT-ALL患者的血涂片、骨髓象、免疫表型、遗传学等结果,结合相关文献分析NT-ALL的性质。结果 该例NT-ALL患者以急腹症为首发表现,根据骨髓形态学、免疫表型被确诊为急性B淋巴细胞白血病(B-ALL),染色体为近四倍体核型(81-103染色体)。结论 成人NT-ALL比较罕见,形态学特点与经典急性淋巴细胞白血病(ALL)有所不同,原幼淋巴细胞体积大或巨大,细胞核形态多不规则,核仁大,有空泡且预后差,这可能与近四倍体核型异常有关。

Abstract:

Objective To study the morphological and clinical characteristics of near-tetraploid acute lymphocytic leukemia(NT-ALL). Methods All the clinical data and laboratory examinations(blood smear,bone marrow morphology,immunophenotype and genetic examinations)of 1 NT-ALL patient were collected for comprehensive analysis. Results The patient had acute abdomen. According to bone marrow morphology and immunophenotype,he was diagnosed as B-acute lymphocytic leukemia(B-ALL),and the chromosome was near-tetraploid karyotype(81-103 chromosome). Conclusions Adult NT-ALL is rare. The morphological characteristics are different from those of classic acute lymphocytic leukemia(ALL). The nuclear shape is irregular,the nucleolus is large,the vacuole is large,and the prognosis is poor,which may be related to the abnormal karyotype of near-tetraploid.

Key words: Chromosome, Near-tetraploid karyotype, Acute lymphocytic leukemia, Morphological characteristic, Prognosis
