本文对我院1984年以来诊断为急性白血病537例患者的外周血象及骨髓象进行回顾性分析,存活3年以上者29例,存活最长者14年。其中生存率>3年以上者依次为M_3>M_2>M_4>急淋白血病。形态学观察“①经维甲酸诱导分化后早幼粒白血病细胞有往成熟阶段分化现象且形态多样化改变者易缓解且生存期长;②缓解过程中从无复发者比曾经复发再次缓解者易达长期生存;③缓解期外周血出现原始细胞将预示复发。 This article retrospectively analyzed peripheral blood and bone marrow images of 537 patients diagnosed as acute leukemia since 1984 in our hospital. 29 patients survived for more than 3 years and 14 years survived the longest. The survival rate of more than 3 years was M3> M2> M4> acute leukemia. Morphological observation "1 After retinoid-induced differentiation of promyelocytic leukemia cells to mature stage of differentiation and changes in morphological diversity is easy to ease and long survival period; 2 remission process from relapse free than once relapsed again ease To achieve long-term survival; 3 remission of the original cells in peripheral blood will predict recurrence.
