| الوصف: | Adjuvant bisphosphonates are often recommended in postmenopausal women with early breast cancer at intermediate-to-high risk of disease recurrence, but the magnitude and duration of their effects on bone mineral density (BMD) and bone turnover markers (BTMs) are not well described. We evaluated the impact of adjuvant zoledronate on areal BMD and BTMs in a sub-group of patients who had completed the large 5-yr randomized Adjuvant Zoledronic Acid to Reduce Recurrence (AZURE) trial. About 224 women (recurrence free) who had completed the AZURE trial within the previous 3 mo were recruited from 20 UK AZURE trial sites. One hundred twenty had previously been randomized to zoledronate (19 doses of 4 mg over 5 yr) and 104 to the control arm. BMD and BTMs were assessed at sub-study entry, 6 (BTMs only), 12, 24, and 60 mo following the completion of AZURE. As expected, mean BMD, T-scores, and Z-scores at sub-study entry were higher in the zoledronate vs the control arm. At the lumbar spine, the mean (SD) standardized BMD (sBMD) was 1123 (201) and 985 (182) mg/cm2 in the zoledronate and control arms, respectively (P < .0001). The baseline differences in sBMD persisted at all assessed skeletal sites and throughout the 5-yr follow-up period. In patients completing zoledronate treatment, BTMs were significantly lower than those in the control arm (α- and β-urinary C-telopeptide of type-I collagen, both P < .00001; serum intact pro-collagen I N-propeptide, P < .00001 and serum tartrate-resistant acid phosphatase 5b, P = .0001). Some offset of bone turnover inhibition occurred in the 12 mo following the completion of zoledronate treatment. Thereafter, during the 60 mo of follow-up, all BTMs remained suppressed in the zoledronate arm relative to the control arm. In conclusion, in addition to the known anti-cancer benefits of adjuvant zoledronate, there are likely to be positive, lasting benefits in BMD and bone turnover. |
