Androgen-deprivation therapy and bone loss in prostate cancer patients: a clinical review.

Androgen-deprivation therapy (ADT) has become a standard of care in the management of advanced prostate cancer or as an adjunct therapy. However, ADT is associated with a well-known deleterious effect on bone health, resulting in a decrease in bone-mass density (BMD) and increased risk for fracture. With the longer life expectancy of prostate cancer patients, improvement of the quality of life has become increasingly important. Therefore, adequate screening, prevention and treatment of BMD loss is paramount. Zoledronic acid and denosumab have shown promising results in recent studies, which has led to the Food and Drug Administration approval of these treatment options in various settings throughout the course of the disease, including the prevention of ADT-associated bone loss. This review focuses on the various parameters that impact BMD loss in men initiating ADT, on the specific effect of ADT on bone health and on various lifestyle modifications and treatment options such as bisphosphonates, osteoclast-targeted therapy and selective estrogen-receptor modulators that have shown promising results in recent studies.
