采用一系列国产抗白细胞抗原单克隆抗体及免疫酶技术(APAAP法),对149例急性淋巴细胞白血病及恶性肿瘤进行了免疫表型测定。在125例ALL中,有T-ALL42例,B-ALL70例,双标记8例,无标记者5例,分别占16%,55%,7%及5%。结果表明,急性淋巴细胞白血病表型呈明显的异质性,但大部分表型具有规律性。免疫表型与FAB分型无相关性。5例病人的白血病细胞对所用抗体未显示阳性反应。 A series of domestic anti-leukocyte antigen monoclonal antibody and immune enzyme technology (APAAP method), 149 cases of acute lymphoblastic leukemia and malignant tumors were immunophenotype measured. Among 125 ALL patients, there were 42 T-ALL patients, 70 B-ALL patients, 8 double-labeled patients and 5 unlabeled patients, accounting for 16%, 55%, 7% and 5% respectively. The results showed that the phenotype of acute lymphoblastic leukemia showed significant heterogeneity, but most of the phenotype with regularity. There was no correlation between immunophenotype and FAB typing. Leukemia cells from 5 patients did not show a positive response to the antibodies used.
