概括
在前列腺癌治疗期间,可以出现雄激素受体 (AR) 基因变异. 在接受雄激素受体向剂 (ARTA) 的患者中,AR放大与更长的进展时间有关.
科学领域:
- 在瘤学瘤学.
- 遗传学 是一个遗传学.
- 药理学 药理学是指药理学的学科.
背景情况:
- 受体 (AR) 基因变异可以在受体抑制和受体向剂 (ARTA) 的选择性压力下发展.
- 关于ARTA治疗疗效和患者结局的这些ARTA变化的临床意义在很大程度上仍未确定.
研究的目的:
- 研究割耐性前列腺癌 (CRPC) 中AR变化的发展.
- 评估ARTA治疗患者的AR变化与临床结果之间的关联.
主要方法:
- 来自PROMISE数据库中接受ARTA并接受基因组测试的540名CRPC患者的回顾性分析.
- 基于基因组测试时间 (ARTA前或后治疗) 的患者分层.
- 临床结果的比较,包括进展的时间和PSA反应,基于AR变化状态.
主要成果:
- 在ARTA前组中,AR增强与相对没有AR变化的患者 (9.6个月;p=0.03) 相比,AR进展的时间 (25.7个月) 与显著更长的时间有关.
- 在ARTA后组中,分别在18.5%和35.7%的患者中检测到AR突变和放大.
- 在ARTA后的队列中,L702H突变是最常见的AR突变 (9.9%).
结论:
- 在CRPC初始ARTA治疗期间,AR放大与进展的延长时间相关.
- 这项研究强调了AR变化在预测治疗反应方面的重要性.
- 需要进一步的前性研究来完善针对特定AR变化的患者的治疗策略.

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.

3.8K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

Men's health issues are increasingly recognized as significant, with several conditions posing common threats. Among these, testicular cancer is especially prevalent in younger men, particularly those aged 20 to 35 years. The disease often manifests as a painless mass in the testicles, sometimes accompanied by a sensation of heaviness or a dull ache.
