Primary outcomePrimary: Total Number of Participants With Leptomeningeal Metastasis Detected (ER Status) — 3; 1 Participants
Summary
This study will prospectively enroll 36 evaluable subjects with breast cancer who are undergoing workup for clinical suspicion of leptomeningeal metastasis (LM). Neuroimaging consisting of MRI of the brain or total spine (or both, as clinically indicated) will be obtained in all patients. Patients will also undergo a lumbar puncture and standard CSF evaluation, which may consist of intracranial pressure measurement, CSF protein, glucose, white and red cell analysis, infectious cultures, as well as conventional cytopathologic analysis (cytocentrifuge). An additional CSF sample will be obtained for evaluation of CSF CTCs by OncoCEETM technology and cell-free DNA (recommended amount: 1 tube, 10 mL) at the time of lumbar puncture.

Eligibility Criteria
Inclusion Criteria
- Adult (18 years or older) patients, with invasive breast cancer, of all racial and ethnic origins
- Undergoing lumbar puncture for clinical or radiographic suspicion of leptomeningeal metastasis
- Provide study-specific informed consent
- Patients with unequivocal or suspicious MRI findings.
- Of those with a definitive diagnosis of LM (i.e. positive CSF cytology), 10 evaluable patients will be accrued.
Exclusion Criteria
- Prior CSF fluid which identified malignant cells after 10 evaluable patients with positive CSF are accrued.
