本文用免疫表型法研究了163例急性白血病原始细胞的性质,特别强调了“异位”表面膜结构的表达。虽然没有抗原包括在我们的面板,除了CD 3显示绝对的谱系限制,免疫分型允许明确的特点,母细胞在90%以上的情况下。确定了四组患者(A、B、C、D)具有不同程度的抗原异位表达。我们将那些表达常规抗原模式而不存在交叉谱系标志物的白血病(74%)归类为A组。归类为B组的样本(18%)显示单一异位膜特异性,显然与总体复合表型不一致;这种“低度偏离”并不妨碍明确的免疫诊断。C型标本(5%)显示与不同谱系相关的标记物混杂共表达(双表型白血病),而D组包括无法分类的表型,其特征是无抗原或仅DR表达。我们的研究结果表明,以一致和逻辑的方式解释膜标记物的复杂表型星座的可能性。
The nature of the blast cells in 163 cases of acute leukemia was investigated by immunophenotyping, with particular emphasis on the expression of “ectopic” surface membrane structures. Although no antigen included in our panel except CD3 revealed absolute lineage restriction, immunological typing allowed a definite characterization of blast cells in more than 90% of cases. Four groups of patients were identified (A, B, C, D) with different degrees of antigen ectopic expression. We classified as group A leukemias (74%) those expressing conventional antigenic patterns, in absence of cross‐lineage markers. Samples classified as group B (18%) showed a single ectopic membrane specificity, apparently discordant with the overall composite phenotype; such a “low‐grade deviation” did not prevent a definite immunodiagnosis. Pattern C specimens (5%) revealed a promiscuous coexpression of markers related to different lineages (biphenotypic leukemias), whereas group D included unclassifiable phenotypes, characterized by no antigen or DR‐only expression. Our findings suggest the possibility of interpreting complex phenotypic constellations of membrane markers in a consistent and logical manner.
