EMAS Position Statements and Clincial Guides
Drug holidays from bisphosphonates and denosumab in postmenopausal osteoporosis: EMAS position statementBisphosphonates are structural analogues of inorganic pyrophosphate, where the oxygen atom has been substituted by a carbon atom. Differences in the R2 side-chain bound to the carbon atom and the nitrogen group determine their variations in duration of action, bone affinity and anti-fracture efficacy [1,2]. Bisphosphonates inhibit enzymes involved in osteoclastic activity, and thus suppress bone resorption [1,2]. The main bisphosphonates are alendronate, risedronate, ibandronate and zoledronic acid, which constitute the first-line therapeutic agents in both postmenopausal and male osteoporosis, as they have well-documented anti-fracture efficacy [1,2].
Osteoporosis management in patients with breast cancer: EMAS position statementBreast cancer remains the most frequent cancer in women and its incidence is increasing. However, the mortality rate has stabilized due to the progress made in the treatment of breast cancer over the last decade. In premenopausal women with hormone receptor-positive breast cancer, the goal of adjuvant treatment is to inhibit the impact of estrogen on the breast, either by blocking the estrogen receptors (with the use of tamoxifen) or by suppressing ovarian function (through surgical oophorectomy or treatment with luteinizing hormone-releasing hormone (LHRH) agonist).
