Eur Urol:恶性前列腺癌根治性放疗后局部失败和生存研究

2019-11-24 AlexYang MedSci原创

高等级前列腺癌(PCa)根治性放疗(RT)后局部失败(LF)的重要性仍旧未知。最近,有研究人员评估了根治性RT后LF的临床意义情况。研究包括了992名患者的数据(593名为格林森等级4,399名为格林森等级5),他们包含在6个随机临床试验中。研究平均跟踪调查时间为6.4年,患者生存均值为7.2年。研究发现,LF与总生存(OS)(风险比(HR)1.70,95%CI 1.37-2.10)、PCa特异性

高等级前列腺癌(PCa)根治性放疗(RT)后局部失败(LF)的重要性仍旧未知。最近,有研究人员评估了根治性RT后LF的临床意义情况。

研究包括了992名患者的数据(593名为格林森等级4,399名为格林森等级5),他们包含在6个随机临床试验中。研究平均跟踪调查时间为6.4年,患者生存均值为7.2年。研究发现,LF与总生存(OS)(风险比(HR)1.70,95%CI 1.37-2.10)、PCa特异性生存(PCSS)(HR 3.10, 95%CI 2.33-4.12)和无远距离转移生存(DMFS)(HR 1.92, 95%CI 1.54-2.39)(所有p<0.001)显著相关。那些没有转换为LF情况的患者发生PCa特异性死亡的风险要比那些转换为LF情况的患者显著更低(HR 0.13,95%CI 0.04-0.41, p<0.001)。另外,那些转换为LF的患者比没有LF情况的患者具有更大的远距离转移(DM)或者死亡风险(HR 2.46,95%CI 1.22-4.93, p=0.01)。

最后,研究人员指出,LF是高等级局部PCa患者OS 、PCSS和DMFS的一个独立预测因子,并且一部分DM事件先于LF事件。LF在干预时需要考虑,也表明了术前强化治疗的合理性。然而,是否这些发现适用于所有男性或者没有并发症的男性仍旧需要进行确定。
