白血病染色体改变的很多资料已应用于白血病的命名、诊断、进一步分类和预测各种患者的预后和存活。迄今,由于种种原因,实体瘤细胞遗传学的研究远不如白血病。通常,实体瘤涉及多种核型的变化,故很难找到原发的细胞遗传学特征,这给查明实体瘤原发性核型改变带来一定困难。而白血病则经常仅存在一种核型的改变。随着时 Many data on chromosome alterations in leukemia have been applied to the nomenclature, diagnosis, further classification of leukemia, and prediction of prognosis and survival in various patients. So far, the study of cytogenetics of solid tumors is far inferior to leukemia due to various reasons. In general, solid tumors involve a variety of karyotypic changes, so it is difficult to find the primary cytogenetic characteristics, which brings certain difficulties in identifying the primary karyotype changes of solid tumors. In leukemia, there is often only one karyotype change. With time
