[Diagnostic work-up of bone metastases of genitourinary tumors and their treatment with bisphosphonates. Interdisciplinary consensus conference, Frankfurt, 2006]

Abstract

The diagnostic algorithm in cases of suspected bone metastases of genitourinary tumors still starts with a scintigraphic examination. Osseous metastases of hormone-refractory prostate cancer require treatment with zoledronic acid. A potential indication is a hormone-sensitive status. Nephrotoxic substances should not be administered simultaneously. To avoid osteonecrosis of the jaw, prior dental examination, oral hygiene, and if necessary dental reconstruction are recommended. Bisphosphonates can be combined with radiation therapy and chemotherapy; additional administration of calcium and vitamin D is not mandatory. It is recommended that patients with bone metastases of renal cell cancer be treated with bisphosphonates approved for this indication. For urothelial carcinoma and other genitourinary tumors, the available data are not sufficient to give a recommendation.
