Pilot Study Evaluating the Utility of OncoCEE (Cell Enrichment and Extraction) Technology, a Novel Immunocytochemical Microfluidic Device, in the Diagnosis of Leptomeningeal Metastasis (LM) From Breast Cancer Through Identification of Circulating Tumor Cells (CTCs) in Cerebrospinal Fluid (CSF)
In Brief
A clinical study evaluating OncoCEE for Breast Cancer and Leptomeningeal Metastasis. Completed, enrolled 14 participants across 1 site.
Detailed 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.

Timeline
Interventions
The CSF sample will be to delivered to Biocept's laboratory for processing, and it will be evaluated for CTCs using OncoCEETM microchannel technology. This CSF sample will also be tested for cell-free circulating tumor DNA (ctDNA).
