Design outcomes
Primary
| Measure | Time frame |
|---|---|
| to measure the intensity of the pain relief of the patients at the end of treatment with a five classes score (TOTPAR = TOTal PAin Relief) | at 12 weeks or at 16 weeks (end of treatment) |
Secondary
| Measure | Time frame |
|---|---|
| To evaluate the pain variation with VAS between V1 and V2, V3, V4, V5. | every 3 or 4 weeks during 12 to 16 weeks |
| To evaluate the pain variation with BPI (=Brief Pain Inventory) and correlate with VAS (=Visual Analog Scale) | every 3 or 4 weeks during 12 to 16 weeks |
| To evaluate the use of analgesic (analgesic score) and the number of patients needing an analgesic radiotherapy between V1 and V5 | every 3 or 4 weeks during 12 to 16 weeks |
| To measure the intensity of the pain relief of the patients with the PAR at each visit | every 3 or 4 weeks during 12 to 16 weeks |
| To evaluate the number of skeletal related events by patient | every 3 or 4 weeks during 12 to 16 weeks |
| To evaluate the effect on functional disability, professional activity (BPI), the PS and overall condition (VAS) between V1 and V5 | every 3 or 4 weeks during 12 to 16 weeks |
| To evaluate the variations of PSA (=Prostate specific Antigen) between V1 and End of study or premature withdrawal | at 12 weeks or at 16 weeks (end of treatment) |
| To evaluate the duration of responses | at 12 weeks or at 16 weeks (end of treatment) |
