Intraoperative brachytherapy for resected brain metastases

Area of Science:

• Neurosurgery
• Radiation Oncology
• Oncology

Background:

• Brain metastases represent the most frequent intracranial malignancies in adults.
• Surgical resection is a primary treatment for diagnosis, symptomatic relief, and mass effect reduction.
• Radiotherapy enhances local control following surgical intervention.

Purpose of the Study:

• To review and compare various treatment modalities for brain metastases.
• To evaluate whole-brain radiotherapy, stereotactic radiosurgery (pre- and postoperative), and brachytherapy.
• To highlight intraoperative brachytherapy, specifically using Cesium-131 (Cs-131) implants.

Main Methods:

• Literature review of established treatments for brain metastases.
• Comparative analysis of patient-related, technical, practical, and radiobiological factors.
• Focused discussion on intraoperative brachytherapy techniques and outcomes.

Main Results:

• Comparison of whole-brain radiotherapy, radiosurgery, and brachytherapy presented.
• Intraoperative brachytherapy, particularly with Cs-131, shows promise.
• Emphasis on technical aspects, benefits, and efficacy of Cs-131 brachytherapy.

Conclusions:

• Various radiotherapy techniques exist for brain metastases management.
• Intraoperative brachytherapy with Cs-131 offers specific advantages.
• Further investigation into Cs-131 brachytherapy outcomes is warranted.
