[Everolimus plus Exemestane in Postmenopausal Metastatic Breast Cancer Patients].

The purpose of our study was to test the efficacy and toxicity of everolimus plus exemestane therapy for breast cancer. Between 2014 and 2015, 20 patients diagnosed with breast carcinoma were selected for this retrospective study. Patients received everolimus plus exemestane. As a result, 4 patients showed a partial response to treatment and the median PFS was 2.5 months (range, 1-9). The most common adverse events (AEs) associated with combination therapy were stomatitis, rash, dysgeusia, and non-infectious lung disease. The AEs reported were mostly grade 1 and 2, and manageable with appropriate intervention. Therefore, everolimus plus exemestane therapy for breast cancer seems to be effective and generally tolerable.
