摘要 目的检测前列腺癌患者血清前列腺特异性抗原(PSA)和Spondin-2水平,分析其与核素骨扫描结果的相关性。方法对泌尿外科住院治疗的215例经病理检查确诊为前列腺癌的患者资料进行回顾性分析,评价血清PSA和Spondin-2与骨扫描结果的相关性,以同期体检的50例正常人作为对照组。根据患者ROC曲线,确定血清Spondin-2用于诊断的临界值。结果 215例前列腺癌患者中,有162例(75.3%)同时进行了血清PSA和Spondin-2以及骨扫描检查,其中骨扫描阳性患者有87例(48.3%)。前列腺癌患者血清PSA水平和Spondin-2水平显著高于对照组(P<0.01);骨扫描阳性前列腺癌患者血清PSA和Spondin-2水平显著高于骨扫描阴性者(P<0.01),相关分析显示Spondin-2与骨扫描检查结果呈显著正相关(r=0.723,P<0.01)。ROC曲线提示Spondin-2>8μg/L时,对前列腺癌诊断的敏感度和特异度分别为100.0%和84.6%。结论 Spondin-2是一个诊断前列腺癌新的血清学标志物,建议>8μg/L为诊断临界值。它相对PSA测试更有利于预测骨扫描阳性结果,并提供相对较高的敏感度和特异度。
