Prise en charge des métastases osseuses du cancer de la prostate. À propos d'un cas

Androgen deprivation therapy with LHRH agonists is the gold standard in the treatment of metastatic prostate cancer. This treatment leads to decrease the bone mass, thus bone mineral density evaluation is recommended after one year of hormonal treatment to measure bone loss. Bisphosphonate is recommended when metastasis occurred during hormonal resistance phase to reduce bone events. The necessity of preventive treatment and the appropriate schedule is not well established. Long term fracture risk should be ideally evaluated with a CT scan and an MRI. Fragmented and focal radiotherapy is considered as the treatment of choice to decrease localized pain. Metastasis surgery has functional results and should be performed before major neurologic symptoms occur. Metabolic radiotherapy is an option for multifocal bone metastases.
