    Summary

    Surgery offers improved survival for select melanoma brain metastasis patients. Prophylactic anticonvulsants are recommended to prevent seizures in patients with brain metastases.

    Area of Science:

    • Neuro-oncology
    • Melanoma Research
    • Cancer Metastasis

    Background:

    • Brain metastases are a significant complication of melanoma.
    • Melanoma brain metastases present unique challenges in diagnosis and treatment.
    • Seizures are a common neurological complication.

    Purpose of the Study:

    • To analyze treatment outcomes for melanoma patients with brain metastases.
    • To evaluate the efficacy of radiation therapy (RT) and surgery.
    • To assess the role of prophylactic anticonvulsants and steroid dependency.

    Main Methods:

    • Retrospective analysis of 81 melanoma patients with brain metastases treated at MSKCC (1978-1980).
    • Patients categorized into groups based on metastasis burden and treatment: RT for multiple metastases, RT for single metastasis, and surgery with or without RT for single metastasis.
    • Survival, steroid dependency, and seizure incidence were analyzed.

    Main Results:

    • Median survival varied significantly by treatment group: 11 weeks (multiple metastases, RT), 9 weeks (single metastasis, RT), and 41 weeks (single metastasis, surgery).
    • Hemorrhagic metastases occurred in 29% of patients with non-contrast CT scans.
    • Seizures affected 48% of patients, often as the first sign of metastasis. Prophylactic anticonvulsants reduced seizure incidence.

    Conclusions:

    • Surgical resection should be considered for highly selected patients with single brain metastases from melanoma.
    • Radiation therapy remains a primary treatment modality for multiple brain metastases.
    • Prophylactic anticonvulsant therapy is advisable to mitigate seizure risk in patients with brain metastases.
