应用流式细胞仪和一组单克隆抗体对５８例儿童急性淋巴细胞白血病（ＡＬＬ）免疫表型进行研究。３２例为Ｂ－ＡＬＬ，１０例为Ｔ－ＡＬＬ，１３例为“淋、髓或Ｔ、Ｂ同时表达的ＡＬＬ”，３例是未分化白血病（ＡＵＬ）。经三年生存概率的统计学处理，Ｔ－ＡＬＬ明显低于Ｂ－ＡＬＬ（Ｐ＜０．０１），且男性发病率明显高于女性（９∶１）。淋、髓或Ｔ、Ｂ同时表达的ＡＬＬ又低于Ｔ－ＡＬＬ和Ｂ－ＡＬＬ（Ｐ＜０．０１），其中５０％患儿在第１年内死亡，表明淋、髓或Ｔ、Ｂ同时表达的ＡＬＬ病情凶险，生存期短 Fifty-eight children with acute lymphoblastic leukemia (ALL) immunophenotype were studied by flow cytometry and a panel of monoclonal antibodies. 32 cases were B-ALL, 10 cases were T-ALL, 13 cases were ALL with leaching, marrow or T and B expression, and 3 cases were undifferentiated leukemia (AUL). T-ALL was significantly lower than B-ALL (P <0.01), and the incidence of male was significantly higher than that of female (9: 1) after three-year survival probability statistics. ALL, T lymphoblastic or T, B expression was lower than T-ALL and B-ALL (P <0.01), of which 50% of children died in the first year, indicating that lymph, marrow or T, B expression The ALL disease is dangerous, short survival
