白血病是造血系统的一种恶性肿瘤,是造血系统白细胞异常增生性疾病,病变主要累及其他器官,增生的血细胞有数量及质量异常,具有恶性肿瘤特征,故亦称“血癌”。老年急性白血病有其特殊的临床和血液学表现,随着社会老龄化趋势,老年急性白血病可能会逐年增多。为深入探讨老年急性白血病的临床特征,笔者对15年来经骨髓细胞形态学及细胞化学等方法确诊的60岁以上老年人急性白血病进行了观察和分析。1 临床特征
Leukemia is a malignant tumor of the hematopoietic system. It is a leukocyte dysplastic disease in the hematopoietic system. The lesions mainly affect other organs. The number and quality of hyperplastic blood cells are abnormal, and they have the characteristics of malignant tumors.
