摘要: 目的 探讨伴t(11;19)(q23;p13)白血病临床实验室特点。方法 回顾性分析21例初诊t(11;19)(q23;p13)患者的临床实验室资料,包括核型分析、荧光原位杂交、融合基因、细胞免疫表型等。结果 21例患者中,16例为t(11;19)(q23;p13.1),核型表现为(11q+,19p-),伴有融合基因MLL-ELL阳性。男7例,女9例。分型诊断:1例AML-M2,3例AML-M4,10例AML-M5,另2例为CMML;5例为t(11;19)(q23;p13.3),核型表现为(11q-,19p+),伴有融合基因MLL-ENL阳性。1例男性,4例女性。分型诊断:3例proB-ALL,1例preB-ALL,1例T-ALL。结论 t(11;19)(q23;p13)为少见的非随机染色体易位,t(11;19)(q23;p13.1)主要在成人急性髓系白血病(AML)出现,且与单核系相关,而t(11;19)(q23;p13.3)主要在婴幼儿及儿童急性淋巴细胞白血病(ALL)中出现。

Abstract: Objective To analyze the clinical and laboratory characteristics of Leukemia with t(11;19)(q23;p13). Methods Twenty-one patients with (11;19)(q23;p13) were reviewed including the data of conventional cytogenetic analysis,fluorescence in situ hybridization (FISH),fusion genes,and immunophenotype. Results Sixteen of 21 patients carry t(11;19)(q23;p13.1),showing 11q+ and 19p- derivatives and positive MLL/ELL fusion genes. Seven males and nine females were definitively diagnosed,among them,one shows M2 ; 3,M4; and 10,M5. The other 2 cases were CMML. Five of 21 patients were t(11;19)(q23;p13.3),exhibiting 11q- and 19p+ derivatives and positive MLL/ENL fusion genes. One male and four females were identified,3 cases were classified as proB-ALL,1 as preB-ALL,and 1 as T-ALL. Conclusions The t(11;19)(q23;p13) abnormality is one of the rare and non-random chromosomal translocations. The t(11;19)(q23;p13.1) are mostly seen in the patients with acute myeloid leukemia (AML) in adults. Comparatively,the t(11;19)(q23;p13.3) frequently occurs in the infants and children with malignancies of lymphoid lineage.
