Age effect on bone mineral density changes in breast cancer patients receiving anastrozole: results from the ARBI prospective clinical trial.

Purpose: We investigated whether age at anastrozole (A) initiation influences the effect of treatment on bone mineral density (BMD). We conducted a post hoc analysis of the dataset of Arimidex Bone Mass Index Oral Bisphosphonates prospective trial, studying the effect of risedronate (R) on BMD of postmenopausal, early breast cancer patients receiving A.

Methods: Patients were stratified into those with normal BMD or mild osteopenia (T > -2) receiving A-only and patients with mild or severe osteopenia (T ≤ -2) or osteoporosis (T < -2.

Management of anastrozole-induced bone loss in breast cancer patients with oral risedronate: results from the ARBI prospective clinical trial.

Introduction: The aim of this multicenter, phase III, prospective open label clinical trial was to investigate the effect of risedronate (R) on bone mineral density (BMD) in postmenopausal, early breast cancer (BC) patients scheduled to receive anastrozole (A).

Methods: Pre-treatment BMD of 213 patients with hormone receptor-positive BC was evaluated at lumbar spine (LS) and hip (HP). Patients were categorized according to their baseline BMD T-score as being at low, moderate and high risk of osteoporosis.

Extended adjuvant hormonal therapy with exemestane has no detrimental effect on the lipid profile of postmenopausal breast cancer patients: final results of the ATENA lipid substudy.

Introduction: Extended adjuvant endocrine therapy for breast cancer with aromatase inhibitors may potentially alter the lipid profile of postmenopausal patients and thus increase the risk of developing cardiovascular disease. In this study, a subprotocol of the ATENA (Adjuvant post-Tamoxifen Exemestane versus Nothing Applied) trial, we compared the effect of the steroidal aromatase inactivator exemestane on the lipid profile of postmenopausal patients with operable breast cancer, in the adjuvant setting, with that of observation alone after completion of 5 to 7 years of primary treatment with tamoxifen.

Methods: In this open-label, randomized, parallel-group study, 411 postmenopausal patients with operable breast cancer, who had been treated with tamoxifen for 5 to 7 years, were randomized to either 5 additional years of exemestane (25 mg/day; n = 211) or observation only (n = 200).
