Abstract

Bone metastases are often asymptomatic and are not diagnosed until after the onset of bone pain. However, bone structural integrity may have diminished considerably before pain onset, resulting in increased risk of skeletal-related events. Therefore, we evaluated whether bisphosphonate therapy was differentially beneficial depending on initiation before or after the onset of bone pain. Exploratory analyses were performed in patients with bone metastases from breast cancer or lung cancer/other solid tumors enrolled in two randomized trials comparing monthly zoledronic acid versus pamidronate (breast cancer) or placebo (lung cancer/other solid tumors). Analyses included proportion of patients with one or more skeletal-related events, time to first skeletal-related event, and skeletal morbidity rate in patients with and without baseline pain. Approximately 80 % of patients reported baseline pain. Similar to overall trial results, zoledronic acid reduced the skeletal morbidity rate in all groups. Although some subsets lacked statistical power, benefits were generally greater in patients without baseline pain. For example, in breast cancer, zoledronic acid increased the 25th quartile of time to first skeletal-related event versus pa...Continue Reading
