Osteoporosis after adjuvant treatment for early-stage breast cancer.

Introduction: Adjuvant treatment of early-stage breast cancer has been associated with bone loss in randomised trials, but evidence from unselected populations is needed. In a single-center study, we assessed the annual percentage change in bone mineral density (∆BMDt) and risk of osteoporosis from two to five years after adjuvant chemotherapy in patients with oestrogen-receptor-positive and oestrogen-receptor-negative tumours.

Methods: Dual energy X-ray absorptiometry (DXA) was performed in 241 recurrence-free Danish breast cancer patients, among whom 157 had a prior DXA scan within two years of chemotherapy ("early").

Change in bone mineral density during adjuvant chemotherapy for early-stage breast cancer.

Purpose: Adjuvant chemotherapy has been associated with loss of bone mineral density (BMD) either as a direct effect or due to glucocorticoids used as supportive care medication. A prospective cohort study was conducted to evaluate changes in BMD from baseline to right after completion of chemotherapy, i.e.
