摘要 目的探讨胸苷激酶1(TK1)和多种恶性肿瘤相关物质(TSGF)能否作为肿瘤标志物。方法应用免疫印迹增强化学发光法和TSGF检测试剂盒分别检测137例肿瘤患者、103例非肿瘤疾病患者和280例健康体检者血清中TK1与TSGF水平,并评价其敏感性、特异性、可用度、阳性预测值、阴性预测值和Youden指数。结果肿瘤患者组TK1和TSGF阳性率虽均显著高于非肿瘤疾病组和健康体检组,但敏感性仅分别为35.0%和27.0%,特异性分别为94.0%和97.1%,可用度分别为41.9%和42.6%,阳性预测值分别为67.6%和77.1%,阴性预测值分别为80.2%和78.8%,Youden指数分别为0.29和0.24。结论在已确诊的恶性肿瘤患者中,TK1和TSGF的阳性率很低,可用度均<43%,有65%~73%的患者会漏诊,不适宜作为检测肿瘤的指标。
