Spinal Palliation in Irradiation for Neoplastic Analgesia and Life Quality

The goal of this clinical trial is to assess the impact of reducing the volume of palliative metastatic bone irradiation on analgesic effectiveness at day 30 and to evaluate the efficiency of telemonitoring in identifying patients who could benefit from Patient-Reported Outcomes (PROs) and require care. These objectives will be addressed in a multicenter, randomized, prospective study with two arms: A standard arm with spinal irradiation without sparing the adjacent vertebrae. An experimental arm with spinal irradiation sparing the adjacent vertebrae. The results will determine whether reducing the irradiated volume can maintain effective pain relief while minimizing side effects.
