Is this trial a fit for you?

Likely a good fit

Ideal candidates include adults aged 18 or older with a history of breast cancer and suspected leptomeningeal metastasis.

Probably not a fit

Patients with central nervous system recurrence of hematologic malignancies or those not eligible for treatment of leptomeningeal disease may not benefit from this study.

What this trial studies

This observational study aims to gather comprehensive data on patients with breast cancer-related leptomeningeal metastasis (LMD), a condition with a poor prognosis and limited treatment options. The study will collect biospecimens, including tissue, blood, and cerebrospinal fluid, to better understand the biology of LMD. Additionally, it will provide rapid diagnostics and multi-disciplinary treatment recommendations through the Johns Hopkins Molecular Tumor Board. By being as inclusive as possible, the study seeks to optimize patient management and correlate clinical outcomes with biological markers.

Why it matters

Potential benefit: If successful, this study could lead to improved understanding and management of breast cancer leptomeningeal metastasis, potentially enhancing patient outcomes.

How similar studies have gone: While studies on leptomeningeal metastasis are limited, the approach of collecting biospecimens and providing multi-disciplinary treatment recommendations is innovative and has not been widely tested.
