研究人员探索了5α还原酶抑制剂对疾病重新分类的影响以及能否作为在前列腺癌患者动态监测的最佳选择。

在本项回顾性研究中,研究人员对在2002年到2015年期间的635名患者进行了积极的监测。在重复活组织切片检查中,有良好的癌症特征的患者,被定义为没有Gleason升级。并被纳入队列。在确诊1年内,患者被确诊或未服用非那司提或杜氏菌。主要终点为等级重新分类,定义在随后的活检中,Gleason评分或Gleason模式的增加。利用多变量Cox比例风险回归分析评估。

在研究中共371例满足入选标准,其中有70(19%)5日内开始服用α还原酶抑制剂共12个月。中位数积极监测时间是53个月,未用5α还原酶抑制剂的检测组中位数积极监测时间是35个月。5α还原酶抑制剂的使用在患者整体或很低/低风险子集。在经历重新分类的患者中,整体比例为13% vs 14% (p = 0.75)。基线临床病理特性的调整后5α还原酶抑制剂没有显着相关重新分类(HR 0.80,95%可信区间0.31 - -1.80,p = 0.62)。此外,在治疗的患者中,对根治性前列腺切除术标本的不良特征没有差异(p = 0.36)。

结论
在接受主动监测的男性患者中,研究人员观察到5α还原酶抑制剂的应用和时间等级分类之间并无明确的联系。
