摘要
对40例中国人急性淋巴细胞白血病(急淋)进行了细胞遗传学的研究,发现正常核型为40%,染色体数量异常占42.5%,染色体结构异常为17.5%,特异染色体异常包括有t(9;22)(q34;q11),t(4;11)(q21;q23)和t(8;14)(q24;q32)及环状染色体等.分析了2例急淋患者初发和复发时核型的变化,显示复发时有附加异常。研究认为细胞形态学,免疫表型和细胞遗传学的联合分析(MIC)有助于急淋的诊断和分型。此外,细胞遗传学检查对于急淋白血病的预后具有重要意义。
A cytogenetic study was performed in 40cases of acute lymphoblastic leukemia (ALL). results showed that in 16 cases (40%) the karyotype was normal in 17 cases (42.4%) quantitative chromosomal abnormalities were identified, and in 7 cases (17.5%) there were structural aberrations. Specific chromosomal anormalies found included translocation t(9;22) (q34;q11), t(4;11) (q21;q23), t(8;14) (q24;q32) and ring chromosome. In 2 cases, karyotype analysis was carried out at the first presentation and at the relapse of the disease, with additional chromosomal abnormalities being found at relapse. It was shown that combined morphologic, immunologic and cytogenetic study (MIC) was valuable for the precise diagnosis and classification of ALL. Cytogenetic study also provided informations independent of other biological parameters in the prognosis of ALL.
