作者报告39例儿童急性淋巴细胞白血病。患者全系1966～1971年间就诊的15个月至16岁儿童。取材于治疗前骨髓,以双盲法用目镜测微尺在骨髓片周边部测定100个原始淋巴细胞的直径,计算直径大于12微米的大原始淋巴细胞(Macrolymphoblast,Mlb)的比例,并分为三组。其形态学发现与临床资料相互关系见表。 The authors report 39 cases of childhood acute lymphoblastic leukemia. The patients were from 15 months to 16 years of age who were treated between 1966 and 1971. Based on the bone marrow before treatment, the diameter of 100 primary lymphocytes was measured by eyepiece micrometer in the periphery of the bone marrow slice by double-blind method. The proportion of macropolymphoblast (Mlb) with a diameter greater than 12 μm was calculated and divided into Three groups. The morphological findings and clinical data related to the table.
