用流式细胞仪检测21例t（8；21）易位急性髓细胞性白血病细胞的免疫学表型，并与无t（8；21）易位急性髓细胞白血病（M2）病人比较．结果：t（8；21）+组与t（8；21）-组CD1，阳性率分别为62％、9％（P＜0．01）．CD34阳性率分别为76.2％、36％（P＜0．05），t（8；21）+组中皆无表达CD7，而t（8；21）-组中CD7阳性率为27．2％（P＜0．05）；两组间CD15、CD13、CD33、CD10表达无显著差异．提示t（8；21）急性髓细胞白血病有独特的免疫学表型特点，对形态学分类法难以分类的急性白血病诊断有一定的价值．
Flow cytometry was used to detect the immunophenotype of 21 acute myeloid leukemia cells transfected with t(8;21) and compared with patients with t(8;21) translocation acute myeloid leukemia (M2). Results: The positive rates of CD1 in t(8;21)+ and t(8;21)-groups were 62% and 9%, respectively (P<0.01). The positive rate of CD34 was 76.2% and 36% (P<0.05). No CD7 was expressed in the t(8;21)+ group, but the CD7 positive rate in the t(8;21)-group was 27.2%. (P<0.05); There was no significant difference in the expression of CD15, CD13, CD33, and CD10 between the two groups. It is suggested that t(8;21) acute myeloid leukemia has unique immunophenotypic characteristics and is of value in the diagnosis of acute leukemia which is difficult to classify by morphological classification.
