Advances in radiotherapy for brain metastases

Area of Science:

• Oncology
• Radiation Oncology
• Neurology

Background:

• Improved systemic therapies increase survival for metastatic cancer patients, leading to a rise in brain metastases.
• Management strategies for brain metastases have evolved significantly over time.
• Whole-brain radiotherapy (WBRT) has been a cornerstone treatment, with stereotactic radiosurgery increasingly used as an alternative or boost.

Purpose of the Study:

• To review the current radiotherapeutic treatment options for brain metastases.
• To discuss the integration of advanced radiotherapy techniques into contemporary management.
• To highlight evolving strategies in managing the increasing incidence of brain metastases.

Main Methods:

• Literature review of current radiotherapeutic treatment options for brain metastases.
• Analysis of historical and evolving roles of whole-brain radiotherapy (WBRT) and stereotactic radiosurgery.
• Discussion of technological and pharmacological advancements in WBRT delivery.

Main Results:

• Brain metastases are increasingly common due to improved cancer survival.
• Stereotactic radiosurgery is shifting from a boost to a WBRT replacement.
• Advancements in WBRT delivery aim to improve safety and efficacy.

Conclusions:

• Radiotherapy remains a critical component in managing brain metastases.
• Integrating advanced radiotherapy techniques is essential for optimal patient outcomes.
• The evolving landscape requires continuous adaptation of management strategies.
