Summary

Solitary metastatic brain tumors with dural extension show similar survival to intraparenchymal lesions, though dural involvement may increase recurrence risk. Surgical resection and radiation therapy are standard treatments for these brain metastases.

Area of Science:

  • Neurosurgery
  • Oncology
  • Neurology

Background:

  • Metastatic brain tumors are common in adults.
  • Dural extension of solitary brain metastases is a distinct clinical entity.
  • Limited data exists on the outcomes of surgically treated solitary metastatic brain tumors with dural extension.

Purpose of the Study:

  • To characterize solitary metastatic brain tumors with dural extension.
  • To compare outcomes of patients with dural extension versus those without.
  • To evaluate the impact of surgical resection and radiation therapy on survival and recurrence.

Main Methods:

  • Retrospective review of 22 patients with solitary metastatic brain tumors and dural extension treated surgically.
  • Comparison with a cohort of 26 patients with solitary intraparenchymal metastatic lesions.

  • Analysis of patient demographics, tumor histology, surgical treatment, radiation therapy, survival, and recurrence patterns.

    • Main Results:

    • Median survival was 11 months for patients with dural extension versus 10 months for those without.
    • Recurrent disease occurred in 41% of patients with dural extension, with increased leptomeningeal disease (14%).
    • Dural resection did not affect survival or recurrence time course.

    Conclusions:

    • Solitary metastatic brain tumors with dural extension have comparable survival to intraparenchymal lesions.
    • Dural involvement may increase the risk of leptomeningeal recurrence.
    • Surgical management and adjuvant therapy should be considered for these challenging cases.
