Efficacy and safety of zoledronic acid in the treatment of bone metastases associated with lung cancer and other solid tumors.
Advanced solid tumors are often aggressive and recurrent, and overall survival remains relatively poor despite contemporary therapeutic interventions. Bone metastases are common in these patients, and skeletal-related events, including bone pain, pathologic fractures, and potentially life-threatening hypercalcemia of malignancy, undermine the quality of patient survival. Bisphosphonates are widely used in the treatment of bone metastases associated with breast cancer and multiple myeloma, but have not been extensively investigated in the treatment of patients with solid tumors other than breast or prostate cancer. However, a new-generation nitrogen-containing bisphosphonate, zoledronic acid, has shown significant clinical benefits in indications in which other bisphosphonates have failed. In a phase III clinical trial in patients with bone metastases from solid tumors other than breast or prostate cancer, treatment with zoledronic acid (4 mg via 15-minute infusion) was well tolerated and significantly decreased the incidence of skeletal-related events and increased the time to first skeletal-related event compared with placebo-treated patients. This was the first demonstration of palliative efficacy for bisphosphonate therapy in patients with bone metastases from a wide variety of solid tumors.
