J Natl Cancer Inst:四激肽释放酶标记物可减少前列腺癌的不必要活检

2015-04-14 丁宁译 MedSci原创

背景:许多血清中前列腺特异性抗原(PSA)水平升高的男性,不患有侵略性前列腺癌而接受了不必要的活检,回顾性研究应用冷冻保存的血清表明四激肽释放酶标记物可预测活检结果。 方法:通过测定6129名PSA (≥3.0ng/mL) 水平升高男性的冻存血清中游离、结合和总PSA水平以及激肽释放酶相关肽酶2的含量,以进行前列腺测试前瞻性、随机试验,从而有利于了解前列腺癌及其治疗。4765名男性提供的抗凝血浆

背景:许多血清中前列腺特异性抗原(PSA)水平升高的男性,不患有侵略性前列腺癌而接受了不必要的活检,回顾性研究应用冷冻保存的血清表明四激肽释放酶标记物可预测活检结果。

方法:通过测定6129名PSA (≥3.0ng/mL) 水平升高男性的冻存血清中游离、结合和总PSA水平以及激肽释放酶相关肽酶2的含量,以进行前列腺测试前瞻性、随机试验,从而有利于了解前列腺癌及其治疗。4765名男性提供的抗凝血浆的标志物水平被纳入了统计模型以预测任何等级和高等级(格里森评分≥7)10芯活检的前列腺癌。该模型通过1364名男性的10倍交叉验证和应用测量血清标志物的独立验证,有了更佳修正。所有统计检验均为双侧。

结果:与PSA和年龄单独比较,四激肽释放酶更能提高前列腺癌的检测。就任何等级的肿瘤而言,四激肽释放酶与PSA和年龄单独比较,曲线下面积(AUC)为0.719(95%置信区间[CI]=0.704~0.734)比0.634(95%置信区间[CI]=0.617~0.651,P <0.001);而就高级别肿瘤而言,比值为0.820(95%CI=0.802~0.838)比0.738(95%CI=0.716~ 0.761)。将高级别癌6%的风险作为一个实证性的终止,1000例PSA水平为3.0ng/ml或更高的男性患者中,该模型将减少428例活检的需要,检测到了119例高级别肿瘤,但同时也会使14/133的高级别肿瘤患者延迟诊断。在只有血清样本可供分析的条件下,模型在男性独立验证中表现出良好的结果。

结论:一个大型的前瞻性研究验证了一种关于激肽释放酶标记的统计模型,并且仅在延迟诊断少量患者的前提下,减少了不必要的活检。
