Nine scales demonstrated responsiveness: three in the ketamine trial population (QLQ-C15-PALPain, FACIT-Pal-14, FACT-G7), six in the octreotide trial population (QLQ-C15-PAL Fatigue; FACIT-Pal PalCare, TOI, Total; FACT-G Physical Wellbeing and Total).
Five procedural pain episodes were examined: the Mini-Mental State Examination was used to assess cognitive function, the Brief Pain Inventory - short form (BPI-SF) to assess intensity and impact of pain on daily activities, a pain and adverse-effect questionnaire to assess the intensity of pain and adverse effects, and the European Organisation for Research and Treatment of Cancer QLQ-C15-PAL to assess QoL.
No dose groups showed significant increases in pain as defined by the generic SF-36 as well as disease-specific EORTC-QLQ-BM22 and EORTC-QLQ-C15-PAL questionnaires.
To determine quality of life (QoL) outcomes after palliation of pain from bone metastases using magnetic resonance-guided high intensity focused ultrasound (MR-guided HIFU), measured using the European Organization for Research and Treatment of Cancer (EORTC) QLQ-C15-PAL and the QLQ-BM22 questionnaires.
