Management of single brain metastases has advanced with improved MRI. Current guidelines favor dexamethasone for initial treatment, discourage routine anticonvulsants, and recommend radiotherapy or local therapies like surgery or radiosurgery based on tumor characteristics and patient status.

Area of Science:

  • Neurology
  • Oncology
  • Radiology

Background:

  • Single brain metastases management has evolved significantly.
  • Improved MRI enhances detection, reducing the percentage of single brain metastases.
  • Solitary brain metastases occur without systemic disease.

Purpose of the Study:

  • To outline current best practices for managing single brain metastases.
  • To provide guidance on treatment selection based on tumor and patient factors.

Main Methods:

  • Review of randomized trials and clinical data.
  • Analysis of treatment outcomes for various interventions.
  • Consideration of tumor size, type, and systemic disease status.

Main Results:

  • Dexamethasone is recommended for initial management in most patients.
  • Fractionated whole brain radiotherapy is indicated for progressive systemic tumors or radiosensitive primaries.
  • Surgery or radiosurgery, often followed by radiotherapy, are effective local strategies.

Conclusions:

  • Radiosurgery is preferred for smaller metastases due to its minimally invasive nature.
  • Craniotomy is indicated for larger, cystic, or complex tumors.
  • Adjuvant radiotherapy may reduce recurrence risk but not improve survival.
