Design outcomes

Primary

MeasureTime frame
Measured before the antineoplastic treatment, 6 months after Visit 1 (basal assessment) and 12 months after Visit 1 (basal assessment): 1. Pain intensity and distress measured using an 11-point (0-10) numerical rating scale (NRS) measure of pain intensity (in the last week) and an NRS for distress (unpleasantness) caused by pain 2. Functional impact of pain and quality of life (QoL) measured using the Brief Pain Inventory (BPI), the Short Form 36 Health Survey (SF-36) and EQ- 5D-3L (EuroQol) 3. Functionality or performance status measured using the Eastern Cooperative Oncology Group (ECOG) scale 4. Sleep quality measured using the Pittsburgh Sleep Quality Index (PSQI) 5. Fatigue measured using the Modified Fatigue Impact Scale (MFIS) 6. Emotional functioning measured using the Brief Measure for Assessing General Anxiety Disorder (GAD7) and the Patient Health Questionnaire (PHQ-9) 7. Catastrophizing measured using the Pain Catastrophism Scale (PCS)
