Brain metastases are a major health issue, affecting nearly 200,000 patients annually. Aggressive local treatments like surgery or radiosurgery offer improved survival and quality of life for select patients.

Area of Science:

  • Neurology
  • Oncology
  • Neurosurgery

Background:

  • Brain metastases pose a significant challenge, with nearly 200,000 US patients annually affected by symptomatic parenchymal lesions.
  • Lung, breast, melanoma, renal, and gastrointestinal cancers are the primary sources of brain metastases.
  • While median survival is less than a year, timely therapy can restore neurological function and prevent complications.

Purpose of the Study:

  • To review the current understanding and treatment strategies for brain metastases.
  • To highlight the prognostic factors influencing survival in patients with brain metastases.
  • To evaluate the role of surgery and radiosurgery in managing brain metastases.

Main Methods:

  • Literature review of studies on brain metastases treatment.

  • Analysis of prognostic factors for survival.
  • Comparison of surgical resection, radiosurgery, and whole-brain radiotherapy.

    • Main Results:

    • Aggressive local therapy (surgery or radiosurgery) for single brain metastases improves survival and quality of life compared to whole-brain radiotherapy alone.
    • Radiosurgery offers comparable local control and survival rates to surgical resection for single lesions.
    • Surgery is best reserved for patients with life-threatening brain metastases; radiosurgery is an excellent alternative for asymptomatic or mildly symptomatic patients with lesions <3 cm.

    Conclusions:

    • Effective treatment of brain metastases is crucial, especially with advances in systemic cancer therapy leading to more patients developing limited systemic disease with brain metastases.
    • Radiosurgery has emerged as a significant treatment modality, providing local control and reversing neurological deficits.
    • Judicious use of available techniques, particularly aggressive local therapy for select patients, offers the best palliation and extended survival.
