Incidence of fractures causing hospitalisation in prostate cancer patients: Results from the population-based PCBaSe Sweden

Conclusion: Prostate cancer patients treated with GnRH agonists or orchiectomy have significantly increased risk of fractures requiring hospitalisation while patients treated with antiandrogen monotherapy had no increase in such fractures. In absolute terms the excess risk in men treated with GnRH agonists corresponded to almost 10 extra fractures leading to hospitalisation per 1000 patient-years. Effects on bone density should be considered for men on long-term endocrine treatment. Unwarranted use of orchiectomy and GnRH agonists should be avoided.
