Locally advanced breast cancer presents significant challenges to the multidisciplinary team, particularly in cases involving hormone receptor
(HR)-positive, HER2-negative tumors, which typically show lower rates of pathological complete response to chemotherapy. Cyclin-Dependent
Kinase (CDK) 4/6 inhibitors are the cornerstone of treatment in metastatic Hormone Receptor (HR)-positive, HER2-negative breast cancer and
have more recently been considered in the adjuvant setting. However, their effectiveness in the neoadjuvant setting remains uncertain.
We report the case of a 55-year-old postmenopausal woman initially diagnosed with metastatic HR+/HER2- breast cancer due to a unique L5
bone lesion. Systemic treatment was initiated with an Aromatase Inhibitor (AI) and a CDK4/6 inhibitor. After six months of treatment, imaging
reevaluation confirmed that the L5 l.. Read More»
