摘要

Patients with hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative early breast cancer who meet the inclusion criteria of the monarchE or NATALEE trials and are thus at increased risk of recurrence benefit from intensified adjuvant endocrine therapy with abemaciclib (improved invasive disease-free survival [IDFS] and overall survival [OS]) for 2 years combined with an aromatase inhibitor (AI) or tamoxifen ± gonadotropin-releasing hormone (GnRH) analogues, or ribociclib (improved IDFS) for 3 years combined with AI ± GnRH analogues. Adequate side-effect management is essential with both agents, particularly during the first 3 months, in order to maintain good quality of life, improve adherence to the planned multi-year treatment, and prevent unnecessary treatment discontinuation. In the metastatic setting, the therapeutic landscape has broadened considerably in recent years, and in hormone-dependent breast cancer, the use of the abovementioned agents enables oral treatment with good quality of life, with a switch to intravenous therapy generally only occurring in the third line.
