Title:
Endocrine Therapy for Hormone Receptor-Positive Metastatic Breast Cancer
Excerpt:
CONTRADICTING EVIDENCE: Targeted Therapy: A nonsteroidal AI and palbociclib may be offered to postmenopausal women with treatment-naive HR-positive MBC, because progression-free survival (PFS) but not overall survival (OS) was improved compared with letrozole alone.
Secondary therapy:
Aromatase inhibitor
DOI:
10.1200/JCO.2016.67.1487
Excerpt:
Ibrance is indicated for the treatment of hormone receptor (HR) positive, human epidermal growth factor receptor 2 (HER2) negative locally advanced or metastatic breast cancer:...in combination with an aromatase inhibitor…in combination with fulvestrant in women who have received prior endocrine therapy.
