最近,来自英国剑桥大学癌症研究中心的一项研究表明,前列腺癌中雄激素受体信号途径和PARP通路之间具有合成致死作用。

越来越多的数据阐释了同源重组(HR)在去势难治性前列腺癌中的缺陷,致使这些肿瘤对PARP抑制作用表现为敏感。最近,研究人员阐明了雄激素受体(AR)来维持HR基因的表达和在前列腺癌中HR活性的直接需求。研究发现,在雄激素阻断治疗(ADT)后,PARP调控的修复通路在前列腺癌中表达上调。更进一步的是,PARP活性的上调对前列腺癌细胞的生存是必需的并且他们还阐释了体内ADT和PARP抑制之间的一个合成致死作用。

最后,研究人员表明,他们的数据展示了ADT能够在去势难治性之前,可以功能性地损伤HR,这种作用可以进一步进行临床探索,即利用PARP抑制剂结合雄激素阻断治疗前期在晚期或者高风险前列腺癌中进行探索。

J Urol:MRI/US融合活检决定局部治疗的适用性

最近,有研究人员评估了局部治疗(FT)在接受多参数核磁共振成像(mpMRI)和靶向活检男性中的适用性,并且关联了根治性前列腺切除术后(RP)的全角组织学。研究对象选自于2010年到2016年靶标活检确定的前列腺癌(CaP)的454名男性,这些前列腺癌的鉴定来源于mpMRI中有病变的区域(ROI)。FT的适用性限制到ROIs中4+3最大的格林森得分,具有或者不具有其他的低风险CaP焦点(GS 3+3

Scand J Urol:他汀类药物使用与雄激素剥夺疗法治疗前列腺癌恶化的关系

在一些观察性的研究中,他汀类药物的使用与男性前列腺癌(PCa)恶化风险和死亡率的减少相关。最近,有研究人员调查了在PCa诊断时他汀类药物的使用与接受雄激素剥夺疗法(ADT)作为起始治疗手段的患有晚期或者转移性PCa男性的PCa恶化之间的关系。 研究群体包括了在2007年到2013年,在2个丹麦泌尿系机构中接受ADT作为起始治疗方法的所有男性病人。主要的结果为定义为去势难治性PCa或者

BJU Int:机器人辅助根治性前列腺切除术对患有骨转移前列腺癌病人有益么?

最近,有研究人员调查了机器人辅助根治性前列腺癌切除术(RARP)在寡转移性前列腺癌(PCa)治疗中围手术期的和肿瘤的结果。研究人员回顾性的分析了79例治疗记录,这些前列腺癌病人是在2005年到2015年间通过RARP或者ADT进行治疗的。在这79名病人中,38名病人进行的是RARP治疗,41名病人进行的是ADT治疗,且不包括局部治疗。寡转移性疾病是通过术前骨扫描检测到5个或者更少的热点来定义的。另

Mol Cancer:研究揭示ZEB1-AS1在前列腺癌细胞增殖及转移中的机制

近期研究表明,长链非编码RNAs(lncRNAs)在肿瘤的发生和进展中起着重要的作用。LncRNA ZEB1义1(ZEB1-AS1)位于ZEB1基因的启动子区,目前对其表达的作用机制知之甚少。使用RACE来获得ZEB1-AS1的序列。采用RNA干扰技术减少ZEB1-AS1的表达。使用腺病毒表达载体增加ZEB1-AS1表达。使用CHIP 和RIP来检测ZEB1-AS1调节ZEB1的表观遗传机制。使用

Eur Urol:将勃起功能恢复的年龄差异考虑入根治性前列腺切除术的利弊。

尽管主动监测越来越多地应用于低危前列腺癌患者的管理中,但许多符合条件的患者仍然接受了手术治疗。患者考虑手术而不是主动监视的一个原因是存在这样一个论点:术后勃起功能的恢复可能性是年龄依赖性的,也就是说,延迟手术的患者可能失去手术后恢复勃起功能的机会。

Int J Cancer:前列腺癌 vs 乳腺癌的发病率和死亡率表明,前列腺癌正在被过度诊断

全球乳腺癌发病率自20世纪70年代末开始一直呈上升趋势。美国8名妇女一生中就会有1人患乳腺癌。中国不是乳腺癌的高发国家,但不宜乐观,近年我国乳腺癌发病率的增长速度却高出高发国家1~2个百分点。2012年我国肿瘤登记地区前列腺癌发病率为9.92/10万,列男性恶性肿瘤发病率的第6位。发病年龄在55岁前处于较低水平,55岁后逐渐升高,发病率随着年龄的增长而增长,高峰年龄是70~80岁。家族遗传型前列腺
