Summary

This trial is testing whether Cs-131 brachytherapy, administered during brain surgery, can help prevent brain tumors from recurring. The safety and effectiveness of Cs-131 will be compared to the standard of care, brain surgery without brachytherapy.

Who is the study for?

This trial is for adults over 18 with recurrent brain cancer who can consent, are able to have an MRI, and are scheduled for brain surgery. They should be in good enough health to perform daily activities (KPS ≥70) and not pregnant or breastfeeding. Excluded are those with infections, immunodeficiency, urgent surgery needs, more than six active brain lesions, intolerance to MRI/CT scans or excessive prior radiation.

What is being tested?

The study tests if Cs-131 brachytherapy during brain surgery helps prevent tumor regrowth compared to standard surgery without it. It's a randomized Phase II trial where the effectiveness and safety of adding Cs-131 at the time of tumor removal will be evaluated against usual surgical care.

What are the potential side effects?

Potential side effects may include risks associated with craniotomy such as infection or bleeding at the site of operation. Specific side effects from Cs-131 brachytherapy could involve localized radiation effects like swelling or damage to surrounding healthy brain tissue.
