Effect of androgen deprivation therapy on bone mineral density in prostate cancer patients / 亚洲男科学杂志(英文版)

ABSTRACT

<p><b>AIM</b>To evaluate the effect of androgen deprivation therapy (ADT) on bone mineral density (BMD) in prostate cancer patients.</p><p><b>METHODS</b>Forty-nine prostate cancer patients with their BMD determined were divided into two groups the non-treated group included 21 patients before the commencement of ADT and the treated group, 28 patients, who had received ADT for more than 1 year. BMD was measured by dual energy X-ray absorptiometry (DEXA) in the lumbar spine (L2-4) and femoral neck.</p><p><b>RESULTS</b>Thirteen (62 %) non-treated and 23 (82 %) treated patients fulfilled the BMD criteria for osteopenia or osteoporosis. Z scores for age-matched control in lumbar spine and femoral neck were -0.9 +/- 0.7 and -0.6 +/- 0.5, respectively, in the treated group, and -1.8 +/- 1.1 and -1.6 +/- 1.0, respectively, in the non-treated group, the differences between the two groups were highly significant (P<0.01).</p><p><b>CONCLUSION</b>Prostate cancer patients who received ADT for more than 1 year had a significantly lower BMD in the lumbar spine and femoral neck than those before the beginning of ADT.</p>
