The combination of an endocrine agent with a CDK4/6 inhibitor is the standard of care in the first-line setting for patients with hormone receptor-positive, HER2-negative metastatic breast cancer. Randomized trials have demonstrated similar and significant improvements in progression-free survival using the three available CDK4/6 inhibitors and led to regulatory approval. However, mature overall survival data now suggest potential differences among the various agents, suggesting an evolution in selection preferences.
对于激素受体阳性、人表皮生长因子受体2阴性的转移性乳腺癌患者,内分泌药物与细胞周期蛋白依赖性激酶4/6(CDK4/6)抑制剂联合使用是一线治疗的标准方案。随机试验表明,使用三种可用的CDK4/6抑制剂在无进展生存期方面有相似且显著的改善,并获得了监管部门的批准。然而,目前成熟的总生存期数据表明,不同药物之间可能存在差异,这表明选择偏好发生了变化。
