Summary

Leptomeningeal metastases (LMM) involve cancer spread to the brain and spine linings. Early diagnosis and treatment are crucial, though prognosis remains challenging for most patients.

Area of Science:

  • Neuro-oncology
  • Cancer Metastasis
  • Neurological Oncology

Background:

  • Leptomeningeal metastases (LMM) represent diffuse leptomeningeal infiltration by cancer cells.
  • Lung and breast cancers are the most common primary sites, with increasing incidence of LMM.
  • Clinical presentation involves multifocal central nervous system (CNS) and cranial nerve involvement.

Purpose of the Study:

  • To review the diagnosis and management of leptomeningeal metastases.
  • To highlight the diagnostic challenges and current therapeutic strategies for LMM.
  • To discuss the prognosis and potential for aggressive treatment in a subset of patients.

Main Methods:

  • Neurological examination to identify CNS involvement.
  • Cerebrospinal fluid (CSF) analysis including cytology and tumor markers.

  • Neuroimaging with T1-weighted gadolinium-enhanced MRI of the entire neuraxis.
  • Radionuclide CSF flow studies for treatment planning.

    • Main Results:

    • CSF analysis is typically abnormal, with positive cytology or tumor markers being diagnostic.
    • MRI demonstrates involved sites and guides treatment decisions.
    • Radionuclide studies aid in assessing CSF compartmentalization for therapy planning.

    Conclusions:

    • LMM diagnosis requires a combination of clinical, CSF, and imaging findings.
    • Standard therapies include radiation, intrathecal, and systemic chemotherapy.
    • While prognosis is generally poor, aggressive treatment may benefit select patients, emphasizing quality of life.
