What this trial studies

This observational trial aims to assess the quality of life and report on toxicity and outcome parameters following local ablative therapy, specifically stereotactic radiotherapy, for patients with 4 to 10 brain metastases. The study will include adults diagnosed with multiple brain metastases from any solid tumor, who have a life expectancy of more than three months. Participants will receive stereotactic radiotherapy in 1 to 5 fractions, and the trial will focus on collecting data regarding their quality of life and treatment outcomes. The study is non-randomized and prospective, allowing for real-world insights into the effectiveness of this treatment approach.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with 4 to 10 synchronous brain metastases from solid tumors and a life expectancy of more than three months.

Not a fit: Patients with brain metastases not suitable for stereotactic radiotherapy or those with certain co-morbidities may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve the quality of life for patients with multiple brain metastases by providing effective local treatment options.

How similar studies have performed: Other studies have shown promising results with stereotactic radiotherapy for brain metastases, indicating that this approach is supported by existing evidence.

Inclusion Criteria:

1. Male or female, ≥ 18 years of age
2. Minimal 4 and up to a maximum of 10 synchronous BM diagnosed on a high resolution contrast-enhanced MRI scan (T1 gadolinium) not dated more than 4 weeks prior to inclusion.
