Zusammenfassung
Die Osteoporose als ein systemischer Verlust des Knochenmineralgehaltes mit erhöhter Frakturinzidenz wurde bisher überwiegend bei Frauen untersucht. Sowohl das Auftreten von Wirbelkörper- und Schenkelhalsfrakturen als auch die damit verbundene Exzessmortalität ist bei Frauen und Männern nachgewiesenermaßen unterschiedlich. Ein der Menopause der Frau entsprechendes Syndrom mit Verlust des Serumtestosterons, „ADAM“ (androgen deficiency syndrome of the aging male) konnte bisher nicht schlüssig nachgewiesen werden. Demgegenüber führt der Verlust von Testosteron durch eine operative oder chemische Kastration bei Patienten mit Prostatakarzinom zu einer Abnahme des Knochenmineralgehaltes und einem erhöhten Frakturrisiko. Mehrere Therapieoptionen, wie z. B. Bisphosphonate, wurden in verschiedenen Interventionsstudien bei der Osteoporose unter hormonablativer Therapie erfolgreich eingesetzt und konnten die Knochendichte signifikant erhöhen. Als neue Therapieoptionen stehen Denosumab (monoklonaler Antikörper gegen RANK Ligand) und Toremifen (ein selektiver Östrogen-Rezeptor-Modulator) zur Verfügung. Beide konnten in kontrollierten Studien signifikant die Rate an Wirbelkörperfrakturen bei Patienten mit nicht-metastasiertem Prostatakarzinom unter einer jahrelangen hormonablativen Therapie reduzieren.
Summary
Osteoporosis is defined as a continuous loss of bone mineral density accompanied by an increased fracture risk in females and males. A fall of estrogen concentrations at the menopause and the consecutive rapid bone loss are an established pathogenic mechanism in female osteoporosis. Males do not have a menopause equivalent during which significant amounts of bone are lost. Several diseases, therapeutic strategies and nutritional deficiencies may also result in bone loss and reduced bone mineral density. Prostate cancer is the most common visceral malignancy in men. Suppression of endogenous androgen production as a therapeutic tool is commonly used in patients with non-metastatic prostate cancer and is associated with significant bone loss and an increased fracture risk.
Androgen deprivation therapy is prescribed both for men with locally advanced or high-risk non-metastatic prostate cancer. Osteoclast inhibition with any of several bisphosphonates improves bone mineral density and reduces fracture risk. Denosumab (a monoclonal antibody against RANK ligand) and toremifene (a selective estrogen receptor modulator) recently have been shown to be effective to reduce vertebral fractures in patients with non-metastatic prostate cancer receiving androgen-deprivation therapy. This overview focuses on cancer-treatment-induced bone loss in patients with non-metastatic prostate cancer.
