肝癌患者可溶性肿瘤坏死因子受体Ⅱ检测的临床意义

目的 进一步了解肝癌患者的异常免疫状态,探讨血清、腹水sTNFRⅡ检测的临床意义.方法 用双单抗夹心酶免疫吸附法检测25例肝癌、25例肝硬化患者血清腹水中和30例正常人血清sTNFR Ⅱ水平.结果 肝癌病人血清sTNFR Ⅱ浓度(9.39±4.10)ng/ml]显著高于正常人和肝硬化患者(P＜0.01),同时肝硬化患者血清sTNFR Ⅱ浓度(0.58±0.18)ng/ml]明显高于正常人(0.31±0.16)ng/ml,P＜0.01].肝癌病人腹水sTNFRⅡ浓度(9.13±5.26)ng/ml]亦显著高于肝硬化腹水sTNFR Ⅱ水平(0.52±0.15)ng/ml,P＜0.01].肝癌、肝硬化患者血清、腹水sTNFR Ⅱ水平显著相关(r=1.00,P=0.00).肝癌血清sTNFRⅡ水平与外周血AFP和血小板数量呈正相关(r=0.432,P=0.05和r=0.513,P=0.03).结论 sTNFRⅡ的检测对反映肝癌患者的异常免疫状态,对肿瘤诊断具有实用价值.
