Brain metastases: what's new with an old problem?

Area of Science:

• Neuro-oncology
• Radiation Oncology
• Medical Oncology

Background:

• Brain metastases represent a significant challenge in cancer care, impacting patient survival and quality of life.
• Management strategies have evolved, necessitating a review of recent therapeutic developments.

Purpose of the Study:

• To summarize key developments in the clinical management of brain metastases over the last decade.
• To evaluate the current evidence for various treatment modalities.

Main Methods:

• Review of randomized trials published in the past decade.
• Analysis of studies comparing whole brain radiotherapy (WBRT) with and without stereotactic radiosurgery (SRS) boost.
• Evaluation of trials investigating SRS alone versus SRS with WBRT.

Main Results:

• Limited role for routine chemotherapy or radiosensitizers in brain metastases management (except for seminoma).
• Established roles for steroids, anticonvulsants, WBRT, surgery, and SRS in selected patients.
• Ongoing research into novel chemotherapy, targeted agents, and radiation sensitizers.

Conclusions:

• Current management integrates steroids, anticonvulsants, WBRT, surgery, and SRS based on individual patient factors.
• Treatment decisions should consider survival, local and overall brain control, and neuro-cognitive outcomes.
• Future research directions include optimizing drug-radiation combinations and reducing radiation toxicity.
