[Pamidronate in the treatment of bone metastases from breast cancer].
Bone metastases afflict over 70% of patients with advanced breast cancer, resulting in impaired quality of life and significant clinical problems. Until appearance of the bisphosphonates there was no specific therapeutic treatment available to manage the symptoms of osteolytic bone metastases. Bisphosphonates are stable chemical analogues of pyrophosphate, and inhibit osteoclast-mediated bone resorption, the treatment is effective in reducing skeletal morbidity in breast cancer with fewer skeletal related events, reduced pain and analgesic consumption, and improved quality of life. As a result, bisphosphonates should now be part of the routine management of metastatic bone disease and multiple myeloma. Promising data have resulted in considerable interest in the possible adjuvant use of bisphosphonates. Pamidronate is an easy to use potent inhibitor of osteolysis, given in conjunction with standard anticancer therapies effectively relieves bone pain and improves performance status. Monthly pamidronate infusions for one or two years in addition to standard anticancer therapy reduce by more than one third the yearly frequency of skeletal-related events. The authors report their practice in which 119 breast cancer patients metastatic to bone received 90-120 mg pamidronate infusion/cycle in addition to standard breast cancer therapy every 3-4 weeks.
