交叉表达淋系和髓系相关抗原的急性白血病(AL)包括伴有髓系抗原阳性的急性淋巴细胞性白血病(My+-ALL)、伴有淋系抗原阳性的急性髓细胞性白血病(Ly+-AML)及多系表达(即同时表达T、B及髓系三系以上的抗原)。而多系表达是AL免疫分型中的少见类型,国内外报道甚少。本研究对以上几种
Acute leukemias (ALs) that cross-express lymphoid and myeloid-associated antigens include Myeloid antigen-positive acute lymphocytic leukemia (My + -ALL), Lymph-antigen positive acute myeloid leukemia ) And multi-line expression (that is, simultaneous expression of T, B and myeloid more than three antigens). The multi-line expression is a rare type of AL immunophenotype, few reports at home and abroad. The study of the above several
