A systematic review and meta-analysis of bone metabolism in prostate adenocarcinoma

<p/> <p>Background</p> <p>Osteoporosis could be associated with the hormone therapy for metastatic prostate carcinoma (PCa) and with PCa <it>per se</it>. The objective of this review is to determine the incidence of bone loss and osteoporosis in patients with PCa who are or are not treated with hormone therapy (ADT).</p> <p>Methods</p> <p>The Medline, Embase, Cancerlit, and American Society of Clinical Oncology Abstract databases were searched for published studies on prostate cancer and bone metabolism. The outcomes assessed were: fracture, osteoporosis and osteopenia.</p> <p>Results</p> <p>Thirty-two articles (116,911 participants) were included in the meta-analysis. PCa patients under ADT had a higher risk of osteoporosis (RR, 1.30; <it>p </it>< 0.00001) and a higher risk of fractures (RR, 1.17; <it>p </it>< 0.00001) as compared to patients not under ADT. The total bone mineral density was lower in patients under ADT when compared with patients not under ADT (<it>p </it>= 0.031) but it was similar to bone mineral density found in healthy controls (<it>p </it>= 0.895). The time of androgen deprivation therapy correlated negatively with lumbar spine and total hip bone mineral density (Spearman's rho = -0.490 and -0.773; <it>p </it>= 0.028 and 0.001, respectively) and with total hip <it>t </it>score (Spearman's rho = -0.900; <it>p </it>= 0.037).</p> <p>Conclusion</p> <p>We found consistent evidence that the use of androgen deprivation therapy in patients with PCa reduces bone mineral density, increasing the risk of fractures in these patients.</p
