New treatment method for brain metastases using fractionated stereotactic radiotherapy

Improving Therapeutic Ratio With Hypo Fractionated Stereotactic Radiotherapy for Brain Metastases

Not applicable Interventional Haaglanden Medical Centre · NCT05346367

This study is testing a new way to treat brain metastases using a different form of radiation therapy to see if it can reduce side effects while still helping patients live longer and feel better.

What this trial studies

This randomized phase II trial investigates a potentially safer treatment for brain metastases by comparing standard stereotactic radiotherapy (SRT) given in one or three fractions to fractionated stereotactic radiotherapy (fSRT) administered in five fractions. The study aims to reduce the incidence of radio necrosis, a significant long-term side effect, while monitoring survival rates, toxicity, and patient-reported quality of life. Participants will be closely monitored to assess the effectiveness and safety of the two treatment approaches.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with at least one brain metastasis from large cell cancer who are suitable for stereotactic radiotherapy.

Not a fit: Patients with small cell lung cancer, germinoma, lymphoma, or those who have previously undergone whole brain radiotherapy or SRT on the current target metastases may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved treatment outcomes and reduced side effects for patients with brain metastases.

How similar studies have performed: Retrospective studies have suggested that fractionated stereotactic radiotherapy may reduce the risk of radio necrosis and local tumor recurrence, indicating potential success for this approach.
