Eur Urol:基于核磁共振成像的前列腺癌积极监测5年结果

2020-05-24 AlexYang MedSci原创

尽管在前列腺癌积极监测(AS)中多参数核磁共振成像的使用越来越多,但是现存的数据均来自小的群体。最近,有研究人员描述了一个AS项目的临床、组织学和放射学结果,该项目中使用了MRI进行监测。

尽管在前列腺癌积极监测(AS)中多参数核磁共振成像的使用越来越多,但是现存的数据均来自小的群体。最近,有研究人员描述了一个AS项目的临床、组织学和放射学结果,该项目中使用了MRI进行监测。

研究群体包括了672名男性,时间为2004年到2017年之间。研究发现,累积随访不少于3800人年(py)(均值;58个月;四分位范围 37-82个月)。大约分别有84.7%(95%CI:82.0-87.6)和71.8%(95% CI: 68.2-75.6)的患者在第3年和第5年处在AS状态。无事件生存(EFS)和无治疗生存(TFS)在基线那些MRI可见(Likert4-5)疾病患者或者继发性格林森模式4患者中较低(对数秩检验;p<0.001)。另外,总共有216名男性进行了治疗。24名死亡,但是均与前列腺癌不相关(6.3/1000 py; 95%CI: 4.1-9.5)。在8名男性中发生了转移(2.1个事件/1000py;95%CI: 1.0-4.3),且27名男性在随访活检中升级了到格林森≥4+3((7.7个事件/1000py; 95%CI: 5.2-11.3)。

最后,研究人员指出,中止、死亡和转移的比例在MRI积极监测中与标准的积极监测相当。在AS第5年,基线MRI可见疾病和/或继发性格林森等级4与转移到积极治疗更大的可能性相关。进一步的研究将聚焦基于基线风险来优化成像间隔。
