Patients with breast cancer face substantial challenges to bone health from bone metastases, as well as from chemotherapy and endocrine therapies that generally elicit disease control at the cost of increased bone turnover. Consequently, maintaining bone health is of critical importance for these patients. Recently reported results from BOLERO-2 showed significant clinical benefits with adding everolimus to exemestane therapy in postmenopausal women with estrogen-receptor-positive breast cancer recurring or progressing despite nonsteroidal aromatase inhibitor therapy. Moreover, exploratory analyses from BOLERO-2 showed that adding everolimus may have beneficial effects on bone turnover and progressive disease in bone in this patient population. These results are supported by preclinical studies in which mTOR inhibition was associated with decreased osteoclast survival and activity. Thus, everolimus therapy may be able to ameliorate the negative effects of estrogen suppression on bone health. This review discusses the effects of mTOR inhibition on bone health during endocrine therapy. (c) 2013 The Authors. Published by Elsevier Ireland Ltd. All rights reserved.
