摘要 目的研究急性淋巴细胞白血病(ALL)患者的染色体异常核型及其与临床特征和近期疗效的关系。方法采用骨髓细胞短期培养法、吉姆萨显带对110例ALL患者进行染色体核型分析。结果110例ALL患者中,正常核型71例(64.5%),异常核型39例(35.5%),染色体核型结构异常者24例(21.8%),数目异常者11例(10.0%),结构及数目异常者3例(2.7%),异常复杂核型1例。伴有t(9;22)(q34;q11)的ALL患者疗效差于其他患者(确切概率法,P=0.045),伴有t(9;22)(q34;q11)的成年人ALL与儿童ALL疗效差异无统计学意义(确切概率法,P=0.506)。结论ALL患者的染色体核型异常具有随机性,较常见的有t(9;22)(q34;q11)、t(4;11)(q21;q23),其疗效较差。 Objective To investigate the chromosome karyotype of acute lymphocytic leukemia (ALL) and its correlation with the clinical feature and efficacy. Methods The chromosomes of bone marrow/ peripheral blood from 110 cases of patients with ALL were prepared after 24 hours culture, and G-banding were used to analyze karyotypes. Results Among 110 patients with ALL, 71 cases (64.5 %) had clonal chromsomal normalities, 39 cases (35.5 %) had elonal chromsomal abnormalities, 24 cases (21.8 %) had chromosome structural abnon^lalities, 11 cases (10.0 %) had chromosome number abnormalities, 3 cases (2.7 %) had chromosome number and structure abnormalities, one case had chromosomal abnormalities complex karyotype. Efficacy in patients with ALL with t(9;22) (q34;qll) was worse than the other patients (Fisher" s exact text, P = 0.045). There was no significant difference on efficacy between in adult ALL associated with t(9;22) (q34;qll) and in children with ALL (Fisher's exact text, P = 0.506). Conclusion Chromosome karyotype of ALL patients is random, chromosomal translocations such as t(9;22)(q34;qll) and t(4;11) (q21;q23) have poorer treatment outcomes.
