应用多聚酶链反应（ＰＣＲ）方法检测６７例淋巴系肿瘤的基因标志，以５例正常人和５例急性非淋巴细胞白血病（ＡＮＬＬ）为对照。结果表明，ＩｇＨ基因重排只见于Ｂ细胞性肿瘤，具有Ｂ系特异性；ＴＣＲγ重排不仅见于Ｔ细胞，也可见于Ｂ细胞；５例ＵＡＬＬ中４例检出ＴＣＲγ重排，提示基因重排在确定克隆细胞来源上优于免疫学方法 The polymerase chain reaction (PCR) method was used to detect the gene markers of 67 cases of lymphatic tumors, and compared with 5 cases of normal people and 5 cases of acute nonlymphocytic leukemia (ANLL). The results showed that the rearrangement of IgH gene was only found in B-cell tumors with B-line specificity; TCRγ rearrangement was found not only in T cells but also in B cells; 4 cases of UALL in 5 patients were found to have TCRγ rearrangement, suggesting that the gene Rearrangement is superior to immunological methods in determining the origin of cloned cells
