摘要
为了解原发性皮肤T细胞淋巴瘤(PCTCL)外周血中克隆性T细胞的存在及其与临床疗效的相关性,分别对25例PCTCL患者经重组α干扰素治疗前后的外周血标本,应用聚合酶链反应(PCR)方法,以通用引物扩增T细胞受体(TCR)γ链编码基因中V(可变区)J(连接区)的结合序列,检测代表克隆性T细胞分子标志的TCR基因重排(GR)。结果发现,25例PCTCL外周血样品中,17例见克隆性T细胞(示TCRGR),经有效治疗后减至3例,治疗前后克隆性T细胞的检出率具显著性差异。说明克隆性T细胞在PCTCL外周血中常见,外周血中克隆性T细胞的动态监测对PCTCL临床疗效的判定有辅助作用。
In order to investigate the presence of clonal T cell in peripheral blood of primary cutaneous T cell lymphoma(PCTCL) and its correlation with therapeutic effect. We analysed peripheral blood samples from a total of 25 patients with PCTCL before and after treatment with recombinant interferon alfa. Universal primers were used to amplify the junctional Ⅴ(variable) J(joining) sequences of T cell receptor γ(TCRγ) genes to detect clonal gene rearrangement (GR) by polymerase chain reaction (PCR). The results showed that TCRGR detection before amd after treatment presented statistically significant difference. This suggests that clonal T cell in peripheral blood with PCTCL is common. Dynamic monitoring of clonal T cell in peripheral blood is helpful to assess the therapeutic effect in PCTCL.
