概括
这项研究介绍了一个60岁女性转移性乳腺癌的病例. 用富尔韦斯特兰特,德诺苏马布和阿贝马西克利布治疗可以实现长期稳定的疾病,具有良好的耐受性.
科学领域:
- 在瘤学瘤学.
- 医学案例研究 医学案例研究
背景情况:
- 一位60岁的女性患有高血压,,功能衰竭和脑梗塞,出现左乳腺质量.
- 活检证实了侵入性导管癌,雌激素受体 (ER) 阳性,孕激素受体 (PgR) 阳性,HER2阴性,Ki-67增殖指数为12%.
- 系统检查显示骨转移,并排除了手术由伴随性疾病.
研究的目的:
- 报告患有转移性乳腺癌和重大并发症的患者的管理和结果.
- 在这个具有挑战性的临床场景中评估组合治疗方案的疗效和耐受性.
主要方法:
- 由于无法切除的疾病,开始服用富尔韦斯特兰特 (500毫克/月) 和苏马布 (120毫克/月).
- 添加abemaciclib (最初300毫克/天) 治疗瘤标志物升高,随后根据耐受性和反应调整剂量.
- 监测瘤标志物,不良事件和疾病状态 (稳定疾病 - SD).
主要成果:
- 组合疗法导致在开始abemaciclib后瘤标志物升高的降低.
- 由于3级中性质衰竭,Abemaciclib的剂量被调整为200毫克/天,后来增加到250毫克/天,以持续减少瘤标志物.
- 在36个月后,患者保持了长期稳定的疾病 (SD),耐受性良好,没有3级或更高的不良事件.
结论:
- 与富尔韦斯特兰特,德诺苏马布和调整剂量的阿贝马西克利布的联合治疗可以成为ER+/PgR+/HER2-转移性乳腺癌和并发症的绝经后妇女的有效和耐受性良好的治疗选择.
- 这一案例凸显了个性化治疗策略和对CDK4/6抑制剂剂量调整在治疗转移性乳腺癌中的重要性.

Inhibition of Cdk Activity
4.7K
The orderly progression of the cell cycle depends on the activation of Cdk protein by binding to its cyclin partner. However, the cell cycle must be restricted when undergoing abnormal changes. Most cancers correlate to the deregulated cell cycle, and since Cdks are a central component of the cell cycle, Cdk inhibitors are extensively studied to develop anticancer agents. For instance, cyclin D associates with several Cdks, such as Cdk 4/6, to form an active complex. The cyclin D-Cdk4/6 complex...

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.
