Stereotactic radiosurgery offers effective palliation for brainstem metastases, achieving a 95% local control rate. This treatment, combined with whole-brain radiation therapy, can improve outcomes for patients with these challenging tumors.

Area of Science:

  • Neurosurgery
  • Radiation Oncology
  • Oncology

Background:

  • Brainstem metastases are associated with a poor prognosis and limited treatment options.
  • Conventional radiation therapy has shown minimal clinical benefit for these tumors.
  • The efficacy of radiosurgery for brainstem metastases has not been previously evaluated.

Purpose of the Study:

  • To investigate the role and outcomes of stereotactic radiosurgery in treating brainstem metastases.
  • To assess the safety and effectiveness of radiosurgery in this specific patient population.

Main Methods:

  • Retrospective review of 26 patients with 27 brainstem metastases treated with stereotactic radiosurgery.
  • Tumor locations included the pons and midbrain; 14 patients had additional metastases.

  • Patients received a median marginal dose of 16 Gy, often combined with whole-brain radiation therapy (WBRT) and chemotherapy/immunotherapy.

    • Main Results:

    • A 95% local control rate was observed for brainstem tumors post-radiosurgery.
    • Median survival was 11 months post-diagnosis and 9 months post-radiosurgery.
    • Thirteen patients improved, 10 remained stable, and three deteriorated; most deaths were due to extracranial disease progression.

    Conclusions:

    • Stereotactic radiosurgery, in conjunction with WBRT, can provide effective palliation for patients with brainstem metastases.
    • While survival rates may be slightly lower than for non-brainstem tumors, radiosurgery offers a viable treatment option.
