Brief Summary:
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.
Detailed Description:
Palliative analgesic radiotherapy (RT) is used to relieve pain in patients with bone metastases. This technique involves irradiating the vertebrae above and below the ones responsible for the pain. Traditional two-dimensional radiotherapy (2D-RT) was characterized by a physical penumbra that could extend up to 50% of a vertebra's height, leading to underdosing of the target volume and, consequently, reduced analgesic effectiveness.
However, computed tomography (CT) scans or CT-based imaging have replaced these practices, allowing for high precision in delineating target volumes. Despite advancements in irradiation techniques, the physical penumbra is now negligible with modern machines, reducing the need for large margins and thereby limiting side effects associated with the irradiation of healthy tissues.
These factors have led us to conduct a clinical trial to assess the impact of reducing the volume of palliative metastatic bone irradiation on analgesic effectiveness at day 30 (D30) and to evaluate the efficiency of telemonitoring in identifying patients who could benefit from Patient-PROs and require care.
These objectives will be pursued 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. This could lead to changes in current palliative radiotherapy practices, reduce toxicity risks, and improve patients' quality of life.
