Impact of Prophylactic Bone Radiation Therapy in Patients With Bone Metastases.
France154 participantsStarted 2026-09-01
Plain-language summary
Radiation therapy is a common treatment for painful bone metastases, proving effective in 1 to 2/3 of cases after 1 to 10 sessions, with stereotactic body radiation therapy (SBRT) likely offering superior results.
Radiation therapy is also used to prevent bone events, although its use is not standardized; the decision to administer it is made by clinicians or through multidisciplinary team (MDT) discussions.
Recently, it has been shown that preventive radiation therapy can reduce the risk of skeletal-related events (SREs) in patients at high risk for bone events.
The objective is to compare active surveillance with preventive radiation therapy in patients at intermediate risk for bone events.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Men or women, 18 years of age or older
* Patients with solid cancer and bone metastases
* Patients with bone lesions considered to be at intermediate risk for skeletal-related events (SINS score between 7 and 12, Mirels 8) or patients with lesions accompanied by Grade 1 epiduritis (Bilsky)
* Enrolled in or covered by a social insurance program
* Patients with an estimated life expectancy of more than 6 months
Exclusion Criteria:
* Hematologic disease
* Patients with a lesion at high risk for skeletal-related events (SINS score of 13 or higher, MIRELS score of 9 or higher, or a multidisciplinary team (MDT) recommendation that surgery is necessary)
* Patients with pain secondary to bone lesions requiring radiation therapy
* Contraindication to radiation therapy due to a history of radiation therapy at the same site or a condition contraindicating radiation therapy
* Pregnant or breastfeeding women
* Contraindication to MRI in cases of spinal lesions; contrast-enhanced CT scan
* Patients unable to understand the study for any reason or to comply with the trial requirements (language, psychological, geographic issues, etc.)
* Patients under legal guardianship or conservatorship
* Patients classified as WHO 3 or 4
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
