摘要 目的 探讨前列腺特异抗原游离与总量比值 (FPSA/TPSA)的测定对前列腺癌诊断的价值 ,分析年龄、TPSA浓度和前列腺慢性炎症等因素对FPSA/TPSA的影响。方法 将 1 75例前列腺疾病患者根据术后病理结果分为 3组 ,即前列腺癌组 (A组 ,1 6例 ) ,前列腺增生症 (BPH)组 (B组 ,1 4 6例 )和BPH伴慢性炎症组 (C组 ,1 3例 )。术前用时间分辨荧光免疫分析方法测定血清FPSA及TPSA ,计算出FPSA/TPSA ,比较各组间的FPSA ,TPSA和FP SA/TPSA ,分析FPSA/TPSA与年龄及TPSA浓度的相关性。结果 ①A ,B ,C 3组的TPSA分别为 (1 0 32± 5 6 1 )ng/ml,(7 86± 4 32 )ng/ml和 (8 87± 5 0 2 )ng/ml,差异无显著性 (P >0 0 5 ) ,FPSA/TPSA分别为 (1 4 9± 6 8) % ,(2 2 5± 7 9) %和 (1 7 2± 5 8) % ,其中A ,B组比较差异有显著性 (P <0 0 1 ) ,与C组比较差异无显著性 (P >0 0 5 ) ;②以FPSA/TPSA =0 1 9(1 9% )为诊断阈值时 ,对前列腺癌诊断的灵敏度、特异度、阳性预测值、阳性拟然比和阴性拟然比分别是 81 3% ,6 8 5 % ,2 2 1 % ,2 2和 0 2 7;③TPSA在 2 0ng/ml≤TPSA <7 0ng/ml范围内FPSA/TPSA与年龄呈一定程度的正相关 (r=0 332 1 ,P <0 0 1 ) ,在 1 5 0ng/ml≤TPSA≤ 2 0 0ng/ml范围内FPSA/TPSA与TPSA呈?
