在NATALEE试验中,在中等风险乳腺癌中发现了 ribociclib 的适度生存益处. 适应性新辅助性内分泌治疗可能有助于确定最有可能从这种密集治疗中受益的患者.
科学领域:
- 在瘤学瘤学.
- 药理学 药理学是指药理学的学科.
- 临床试验 临床试验
背景情况:
- 在NATALEE试验中,评估了辅助性 ribociclib 对于激素受体阳性/人体表皮生长因子受体-2-阴性 (HR+/HER2-) 晚期乳腺癌.
- 经过3年的 ribociclib 治疗,观察到 4.9% 的绝对无侵袭性疾病生存益处.
- 对 ribociclib 的初级耐药性发生在中等风险患者的小组中,限制了治疗疗效.
研究的目的:
- 为了应对识别那些将从密集辅助 рибоциклиб治疗中获益最多的患者的挑战.
- 探索适应性新辅助性内分泌疗法 (NET) 作为查工具的潜力.
主要方法:
- 对NATALEE试验数据的分析,重点关注中等风险HR+/HER2亚组.
- 讨论适应性新辅助性内分泌治疗在患者选择中的作用.
主要成果:
- 在中等风险HR+/HER2-人群中,ribociclib提供了显著的,但不是普遍的益处.
- 一些患者表现出对 ribociclib 的初级耐药性,从治疗中获得最小的益处.
- 三年里博西基利布疗程的成本效益和毒性要求对所有中等风险患者进行仔细考虑.
结论:
- 对于所有中等风险HR+/HER2-乳腺癌患者来说,三年期的 ribociclib 疗程可能不是最佳的.
- 适应性新辅助性内分泌疗法对选择那些最有可能对密集辅助性 рибоциклиб治疗做出反应的患者显示出希望.
- 需要进一步的研究来完善辅助疗法的患者选择策略.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
