[Efficacy and Safety of Everolimus plus Exemetane in Postmenopausal Endocrine-Responsive Metastatic Breast Cancer Patients].

Everolimus and exemestane combination therapy represents a treatment option for estrogen receptor(ER)-positive metastatic breast cancer. We evaluated the efficacy and safety of everolimus and exemestane therapy, retrospectively. After a median follow-up of 10.5 months, the median progression-free survivalin patients was 4.7 months. The clinicalbenefit rate was 27%and the disease controlrate was 64%. The most common all-grade adverse events(AEs)were stomatitis(82%) and non-infectious lung disease(27%). The most commonB3 grade AEs were cellulitis(18%)and hyperglycemia(18%). The AEs reported were mostly grade 1 and 2, and manageable with appropriate intervention. Combination therapy with everolimus and exemestane appears to be a useful addition for ER-positive metastatic breast cancer, with carefulmanage- ment of specific AEs.
