JAMA Oncol:骨靶向放射性同位素治疗去势抵抗性前列腺癌骨转移男性的总生存研究

2020-01-08 AlexYang MedSci原创

α放射和β放射骨靶向放射性同位素(RIs)已经开发用于治疗具有去势抵抗性前列腺癌(CRPC)的男性。到目前为止,只有1个阶段3试验阐释了α放射RI 镭223(223Ra)与标准治疗比较下的总生存(OS)情况,而α放射和β放射RIs的比较还没有报道。最近,有研究人员评估了骨靶向RIs治疗的CRPC骨转移患者的OS情况,并比较了α放射RIs和β放射RIs治疗效果。研究发现,基于包含2081名患者的6个

α放射和β放射骨靶向放射性同位素(RIs)已经开发用于治疗具有去势抵抗性前列腺癌(CRPC)的男性。到目前为止,只有1个阶段3试验阐释了α放射RI 镭223(223Ra)与标准治疗比较下的总生存(OS)情况,而α放射和β放射RIs的比较还没有报道。最近,有研究人员评估了骨靶向RIs治疗的CRPC骨转移患者的OS情况,并比较了α放射RIs和β放射RIs治疗效果。

研究发现,基于包含2081名患者的6个随机临床试验表明,与不使用RI相比,RI的使用与OS显著相关(HR, 0.86; 95% CI, 0.77-0.95; P=0.004),并且存在高度的遗传异质性(χ25=24.46; P<0.001; I2=80%),但是上述相关性在RE模型中消失(HR, 0.80; 95% CI, 0.61-1.06; P=0.12; τ2=0.08)。遗传的异质性可以由RI的类型和包含275名患者的2个离群试验来解释;OS益处在α放射RI 223Ra中显著更高(HR, 0.70; 95% CI, 0.58-0.83),但是在β放射RI 锶89中不显著(HR, 0.96; 95% CI, 0.84-1.10)(P=0.004)。将离群试验排除后,使用FE模型时总的HR为0.82(95% CI, 0.73-0.92; P<0.001),使用RE模型时HR为0.80(95% CI, 0.65-0.99; P=0.04; τ2=0.02)(试验异质性:χ23=6.51; P=0.09; I2=54%)。无症状性骨骼事件(SSE)生存的HR在FE模型中为0.81(95% CI, 0.69-0.93; P=0.004),在RE模型中为0.76(95% CI, 0.58-1.01; P=0.06; τ2=0.04)(试验异质性:χ23=6.71; P=0.08; I2=55%)。另外,与不使用RI相比,使用RI造成更多的血液毒性作用(OR, 1.48; 95% CI, 1.17-1.88; P=0.001)。

最后,研究人员指出,在转移性CRPC中,骨靶向α放射RIs能够显著的改善OS和无SSE生存,而β放射RIs不能产生上述效果。考虑到试验间的异质性,这些结果的普适性还需要谨慎对待。

叶定伟:晚期前列腺癌治疗进展盘点

晚期前列腺癌发生转移或者去势抵抗是目前前列腺癌治疗中较为棘手的问题。全身治疗的手段包括激素治疗、化疗、免疫治疗及放射性核素等。对于某些特殊患者亚群,新型基因靶向药物PARP抑制剂和PD-1/PD-L1抑制剂的前期临床试验结果也是非常令人鼓舞的。本文就2019年度晚期前列腺癌领域治疗的研究进展作一总结性回顾。 近年来前列腺癌在我国男性中的发病率呈不断上升势态,发病率增高和人口老龄化、生活方

J Clin Oncol:局部前列腺癌中雄激素阻断治疗和外束放射治疗顺序研究

剂量升级的放疗(RT)和雄激素阻断治疗(ADT)是局部前列腺癌(LPCa)的一种标准的治疗方法。而这些疗法的最优顺序仍旧不清楚。最近,有研究人员在III期试验中比较了新辅助治疗与同时进行ADT治疗在结合剂量升级的前列腺RT(PRT)时的治疗效果情况。研究包括了432名患者,并随机分配到新辅助治疗组(n=215)或者同时治疗组(n=217)。研究发现,在第10年,生化无复发生存率(bRFS)在2个小

Oncogene:染色质修饰酶系统分析鉴定了KDM3B是趋势抵抗性前列腺癌的关键调控因子

雄激素阻断治疗(ADT)是手术治疗失败或者放疗失败前列腺癌(PCa)患者的标准治疗方法。虽然刚开始治疗时很有效,但是总是复发成为一种更加具有侵入性的去势抵抗性前列腺癌(CRPC)。之前的研究阐释了染色质修饰酶在转变为CRPC时具有关键的作用。然而,潜在的药理学靶标鉴定的很少。最近,有研究人员进行了染色质修饰酶shRNA筛选,这些染色质修饰酶之前报道参与了细胞的分化作用。研究人员发现改变组蛋白甲基化

Brit J Cancer:重定位筛选鉴定了甲苯咪唑可作为临床候选药物协同多烯紫杉醇治疗前列腺癌

多烯紫杉醇化疗对前列腺癌的生存影响不大。到目前为止,对组合药物治疗方法的开发还没有形成新的治疗方法。最近,有研究人员尝试开发了一种新的治疗策略,即通过增强多烯紫杉醇的治疗效果来解决前列腺癌的化疗抗性。研究发现,甲苯咪唑(一种能够抑制微管组装的驱虫药)被选择为首选药物,能够与在体外和体内试验中与多烯紫杉醇介导的细胞杀伤起到协同作用。微观结构的双重靶向与G2/M有丝分裂阻断的增加和促进细胞死亡有关。令

Cell Death & Differentiation:去泛素化酶USP33能够抑制多烯紫杉醇诱导的细胞凋亡

去势抵抗性前列腺癌的治疗(CRPC)仍旧面临许多挑战。多烯紫杉醇是CRPC患者中常用的一种化疗药物。然而,基于多烯紫杉醇的化疗常常会引起多烯紫杉醇抗性,部分是CRPC细胞对多烯紫杉醇诱导的细胞凋亡抗性。最近,有研究人员报道了去泛素化酶USP33能够抑制多烯紫杉醇诱导的前列腺癌细胞死亡,包括了不依赖雄激素的前列腺癌细胞。USP33在前列腺癌细胞和组织中过表达。USP33表达的抑制或者敲除能够增强多烯

J Clin Oncol:局部前列腺癌的分子生物标记:ASCO指南

最近,有研究人员提供了一个基于前列腺癌可利用生物标记的推荐指南,旨在改变积极监测患者的选择、临床显著疾病的鉴定、前列腺切除术后辅助治疗与挽救性放疗的选择、以及解决一些新出现的问题,比如组织生物标志物与核磁共振成像的相对值情况。研究人员共鉴定了555个相关的研究,选择了其中的77个加上专家小组选择的32个额外的参考。研究发现,很少的生物标记在多个群体中具有有效的测试结果,并且这些测试中只有5个目前已
