目的研究急性白血病患者各亚型和年龄组构成比的关系。方法对305例初发急性白血病患者的亚型和年龄进行统计分析。结果青少年组,青壮年组,中老年组发病率分别是12.5%(38/305),39.3%(120/305),48.2%(147/305)。急性淋巴细胞白血病(ALL):青少年组发病占63.2%,中老年组发病比例仅6.1%;急性髓系白血病(AML):中老年组发病比例占55.1%,青少年组发病率最低是5.8%。M5发病较为集中在中老年组,M3主要集中在青壮年组。ALL-L2和AML-M2高发于各年龄段。结论急性白血病患者各亚型和年龄组构成比之间关系的研究,对疾病的诊断治疗有重要的应用价值。
Objective To study the relationship between subtypes and age groups in patients with acute leukemia. Methods The subtype and age of 305 newly diagnosed acute leukemia patients were statistically analyzed. Results The incidence rates of adolescent group, young adult group and middle aged group were 12.5% (38/305), 39.3% (120/305) and 48.2% (147/305) respectively. Acute lymphoblastic leukemia (ALL): 63.2% of adolescents and 6.1% of middle-aged and elderly patients. Acute myeloid leukemia (AML) accounted for 55.1% of middle-aged and elderly patients and 5.8% of adolescents. M5 incidence is more concentrated in the middle-aged group, M3 mainly concentrated in young adults. ALL-L2 and AML-M2 high incidence in all age groups. Conclusions The study of the relationship between the composition ratio of each subtype and age group of patients with acute leukemia has important application value in the diagnosis and treatment of the disease.
