众所周知中危与高危局限性前列腺癌的辅助治疗减少这种疾病的死亡人数。总生存率(OS)的替代指标可以加快新辅助疗法的评价。

众所周知中危与高危局限性前列腺癌的辅助治疗减少这种疾病的死亡人数。总生存率(OS)的替代指标可以加快新辅助疗法的评价。

近日在JCO上发表的一篇文章共完成了102项或正在进行的随机试验,并从28个试验中收集了28905例患者的信息。对来自24个试验的21140例患者和来自19个试验的12712例患者分别测定了无病生存期(DFS)和无转移生存率(MFS)。研究人员通过使用两阶段元分析验证模型评估了OS的替代指标DFS和MFS,确定OS与中间临床终点的相关性及OS与治疗对两个中间临床终点影响的相关性。

临床试验是从1987年到2011年招募患者。平均随访10年后,21140名男性中的45%和122712名男性中的45%经历了DFS和MFS事件。DFS的61%和MFS的90%来自辐射试验,而DFS的63%和MFS的66%有高危疾病。在患者水平,Kendall'sτOS与DFS和MFS的相关性分别为0.85和0.91。在试验水平,加权线性回归的8年生存率与5年DF和MFS的R2分别为0.86(95% CI,0.78至0.90)和0.83(95% CI,0.71至0.88)。由危险比测定的治疗效果,替代指标和OS密切相关(R2,DFS为0.73 [ 95%CI,0.53-0.82 ] 和MFS为0.92 [ 95% CI,0.81-0.95 ])。

由上述研究可见MFS是局限性前列腺癌OS强有力的替代。
