Management of castration-resistant prostate cancer: bisphosphonates and emerging therapies

Approximately 70% of patients with prostate cancer will develop bone metastases that often lead to bone pain and skeletal-related events. Several bisphosphonates have shown promising activity for palliating pain. Only zoledronic acid has significantly delayed the onset and reduced the incidence of skeletal-related events in men with castration-resistant prostate cancer. In addition, studies suggest that bisphosphonates have anticancer activity that may prevent disease progression and improve survival. Clodronate was shown to improve survival in a study of men with metastatic androgen-sensitive prostate cancer. Emerging therapies are being investigated for their ability to maintain bone health. The findings presented herein highlight the importance of bone-targeted therapies for patients with bone metastases from prostate cancer.

Preserving functional independence in elderly patients with cancer-associated bone disease: the role of zoledronic acid

Increases in life expectancy in the developed world will inevitably lead to larger numbers of elderly patients with cancer-associated (malignant) bone disease. Most elderly patients with metastatic cancer also suffer from numerous comorbidities. The management of bone health in this setting requires special consideration. This article centers on malignant bone disease in the elderly and the role of bisphosphonates in geriatric oncology. The challenges involved in the treatment of older patients with bone metastases are described, and the potential utility of bisphosphonates, such as zoledronic acid, is discussed. Moreover, recent data from several large clinical trials suggest that zoledronic acid provides additional benefits, including antitumor effects that may extend beyond the preservation of bone health and prevention of skeletal-related events.
