Hormone-dependent breast cancer can be successfully treated by either blocking the estrogen receptor, as with tamoxifen, or reducing the production of estrogens, as with aromatase inhibitors. Exemestane is a third-generation aromatase inhibitor used in the treatment of estrogen-receptor-positive breast cancer

Breast Cancer Trials of Oral Everolimus 2 (BOLERO-2), a phase III study in postmenopausal women with estrogen receptor-positive breast cancer progressing despite nonsteroidal aromatase inhibitor therapy, showed statistically significant benefits with adding everolimus to exemestane. Moreover, in preclinical studies, mammalian

Specific adverse events (AEs) associated with endocrine therapy and related to depletion or blocking of circulating estrogens may be related to treatment efficacy. We investigated the relationship between survival outcomes and specific AEs including vasomotor symptoms (VMSs), musculoskeletal adverse events
