Comparing two types of radiotherapy for brain metastases after surgery

Hypofractionated Stereotactic Radiotherapy Versus Single Fraction Stereotactic Radiosurgery to the Resection Cavity of Brain Metastases After Surgical Resection - A Prospective, Randomized, Controlled, Monocentric Phase III Trial

Not applicable Interventional Technical University of Munich · NCT05160818

This study is testing whether a new type of radiation treatment for brain tumors after surgery works better than the standard method for helping patients keep their tumors under control.

What this trial studies

This clinical trial investigates the effectiveness of hypofractionated stereotactic radiotherapy (HFSRT) versus single fraction stereotactic radiosurgery (SRS) for patients who have undergone surgical resection of brain metastases. A total of 126 patients will be randomly assigned to receive either HFSRT or SRS, with the primary goal of determining which method provides better local control of the tumor at the resection site after 12 months. The study will utilize advanced imaging techniques and follow-up assessments to monitor patient outcomes and ensure safety. The trial aims to clarify the optimal radiation treatment approach for this patient population.

Who should consider this trial

Good fit: Ideal candidates include adults over 18 with one to three resected brain metastases and a performance status of KPS greater than 60%.

Not a fit: Patients with leptomeningeal disease, hematological malignancies, or those who have previously received brain irradiation may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved local control of brain metastases, enhancing patient outcomes and survival rates.

How similar studies have performed: Previous studies have shown promising results with both HFSRT and SRS, but this specific comparison in a randomized controlled setting is novel.
