当前,外周T细胞淋巴瘤(PTCL)和血管免疫母细胞性T细胞淋巴瘤(AITL)中CD30的表达引起人们的极大兴趣,因为针对CD30的靶向治疗可有临床获益,但CD30在这些肿瘤中表达的临床和治疗相关性仍未可知。本研究的目的是改善AITL和PTCL-非特殊类型(NOS)中CD30表达的量化。第二个目的是确定CD30阳性细胞是否显示B细胞或T细胞表型。
一组37例PTCL病例基因表达分析表明连续TNFRSF8表达谱。这提示我们通过逆转录聚合酶链反应(RT-PCR)进一步研究51例不同系列(43例AITLs和8例PTCL-NOSs)常规切片中CD30免疫组化(IHC)表达和mRNA水平。PAX5/CD30,CD3/CD30和LEF1/CD30双染研究CD30阳性细胞表型。
IHC染色显示大多数(90%)病例呈现一定水平CD30表达(1%-95%);14%病例呈高水平表达(>50%肿瘤细胞)。10%病例未检测到CD30表达。定量RT-PCR结果很大程度上证实了这些发现,总体CD30IHC和mRNA水平之间呈中等强度相关(r=0.65,p=1.75e-7)。
44例阳性病例(98%)含CD30阳性B细胞(PAX5),而42例(93%)中检测到非典型CD30阳性T细胞。总之,我们的数据显示大多数AITL和PTCL-NOS病例表达CD30,呈极其不稳定的CD30表达水平,可通过IHC或RT-PCR技术测量。
