摘要 笔者对52例肝癌组织和癌旁组织用CD4和CD25双重酶标免疫组化染色标记Treg和CD4+T细胞,对20例肝癌组织和癌旁组织用CD8EnVision法染色标记CD8+T细胞,光镜下计数阳性细胞,对癌组织中Treg细胞和CD4+T,CD8+T及CD4+T/CD8+T值进行相关性分析,并用正常肝组织作对照。结果示8例正常肝组织中未发现Treg细胞。52例肝癌、癌旁组织中Treg细胞单个高倍视野平均数分别为7.6308±2.8368和5.1654±1.6718(P=0.000);肝癌中Treg细胞数目与肿瘤大小、有无子灶、有无癌栓及肿瘤临床病理分期有关,组间差异有显著性(P<0.05),而与患者年龄、性别、有无肝硬化、术前AFP浓度、肿瘤有无包膜及肿瘤Edmondson分级无明显关系(均P>0.05);肝癌中Treg细胞数量与其浸润性CD4+T淋巴细胞的数量以及CD4+T/CD8+T值呈显著负相关(r=-0.539,P=0.014;r=-0.545,P=0.000),而与浸润性CD8+T淋巴细胞的数量分布无关(r=-0.403P=0.078)。提示肝癌微环境中的Treg细胞可能通过抑制肿瘤局部免疫,使肿瘤细胞逃避免疫监视,促进肿瘤的进展以及侵袭或转移;肝癌组织中的Treg细胞数量可能作为判断肝细胞癌预后的指标之一。
