概括
对于转移性割抵抗性前列腺癌 (mCRPC),与cabazitaxel相比,dcetaxel重试可改善初始dcetaxel没有进展的患者的整体存活率. 这表明dcetaxel重试是一种可行的治疗选择.
科学领域:
- 在瘤学瘤学.
- 药理学 药理学是指药理学的学科.
- 临床医学 临床医学
背景情况:
- 多塞塔克塞尔是转移性割抵抗性前列腺癌 (mCRPC) 的标准治疗方法.
- 卡巴西塔克塞尔 (Cabazitaxel) 是一种相关的纳税基因,已被批准用于mCRPC患者,这些患者先前接受过多塞塔克塞尔治疗.
- 在mCRPC之前使用dcetaxel后,dcetaxel重复挑战与cabazitaxel的比较有效性尚未得到充分确立.
研究的目的:
- 为了比较dcetaxel的临床结果,重新挑战与cabazitaxel.
- 为了评估mCRPC患者在先前的多塞塔克塞尔治疗期间没有经历疾病进展.
主要方法:
- 退伍军人事务医疗保健系统的回顾性队列研究.
- 使用治疗权重的逆概率来控制混因子.
- 包括化学无效的mCRPC接受初始多塞塔克塞尔治疗而没有进展的患者.
主要成果:
- 与cabazitaxel (407名患者,中位数9.6个月) 相比,docetaxel重试 (262名患者) 的整体存活时间明显更长 (中位数为12.3个月).
- 总生存的危险比为0.81 (95% CI,0.55-0.99;P=.04),有利于多塞塔克塞尔重试.
- 二次结局,包括前列腺特异性抗原反应和到下一次治疗或死亡的时间,也对多塞塔克塞尔重试有利.
结论:
- 与cabazitaxel相比,docetaxel的重试与改善的整体存活率有关.
- 研究结果支持将多塞塔克塞尔重试作为mCRPC患者的治疗选择,这些患者在之前的多塞塔克塞尔治疗中没有进展.
- 进一步的研究可能会探索mCRPC中基于税的疗法的最佳测序.

Treatment Resistant Cancers
3.7K
Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...

Targeted Cancer Therapies

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.
