Strontium-89 Chloride in Combined Treatment of Hormone Resistant Prostatic Cancer

Abstract

Hormone resistant phase of prostatic cancer develops after 16-24 months of hormone therapy of metastatic prostatic cancer. Radiopharmaceutical method of treatment is essential for pain control in multiple metastases in the bones; we mean the use of beta-emission isotope strontium-89 chloride (metastrone). Total systems radiotherapy by strontium-89 chloride was carried out as stage III of multiple modality treatment in 90 patients with metastatic hormone-resistant prostatic cancer (HRPC) within the framework of randomized study. Before radiopharmaceutical therapy 18% patients complained of pronounced pain syndrome, 50% presented with moderate pain syndrome, and pathological fractures were diagnosed in 12% patients. Therapy with strontium-89 chloride led to stabilization of the pain syndrome during therapy in 72.7% and to its progress in 27.3% patients. This therapy was well tolerated in general. It can be used as a stage in combined treatment of HRPC patients.
