迄今对急性淋巴细胞白血病的病因仍不十分了解。但已证明同卵双生发生本病的高度一致性,先天免疫缺陷病人发病频率的增加,这些都提示遗传因素在病因上起作用。有关白血病发生的人类的和实验系统的研究表明,淋巴细胞功能障碍可能与病因有关,此外从动物模型和流行病学的研究也可以断定,遗传和外界因子部是人类白血病发 So far the cause of acute lymphoblastic leukemia is still not well understood. However, it has been demonstrated that there is a high degree of homogeneity of the disease in identical twins and an increased frequency of occurrence of patients with congenital immunodeficiency, all of which suggest that genetic factors contribute to the etiology. Human and experimental systems for the development of leukemia have shown that lymphocyte dysfunction may be related to etiology. In addition, from animal models and epidemiological studies, it can be concluded that the hereditary and exogenous factors are human leukemia
