Randomized Controlled TrialFunctional interference clusters in cancer patients with bone metastases: a secondary analysis of RTOG 9714.
To explore the relationships (clusters) among the functional interference items in the Brief Pain Inventory (BPI) in patients with bone metastases. ⋯ Palliative radiotherapy is effective in reducing bone pain. Functional interference component clusters exist in patients treated for bone metastases. These clusters changed over time in this study, possibly attributable to treatment. Further research is needed to examine these effects.
