Accurately detecting and quantifying tumor cells in cerebrospinal fluid (CSF) is essential for diagnosing, monitoring, and managing central nervous system (CNS) malignancies—particularly leptomeningeal metastases (LM) and other aggressive cancers that spread to the CNS.
CNSide Diagnostics’ CSF assay is designed to meet this clinical need by delivering high-resolution, comprehensive data that helps physicians make more informed treatment decisions.

Our platform is designed to combine tumor cell enumeration, immunocytochemistry (ICC), FISH, and next-generation sequencing (NGS) into a single workflow, enabling deeper biological insight into each patient’s disease. These capabilities empower clinicians to move beyond limited traditional diagnostics and toward more precise, personalized CNS cancer care.

Expert Insights: Dr. Andrew Brenner Discusses the Value of CNSide’s Diagnostic Approach

To explore this further, Healio recently featured a Q&A with Andrew Brenner, MD, PhD, member of the CNSide Diagnostics Scientific Advisory Board, discussing how CSF-based assays are advancing the management of LM and other CNS tumors.

In this interview, Dr. Brenner highlights how assays like CNSide® may help clinicians:

• Detect tumor cells earlier and with higher sensitivity
• Quantify disease burden more reliably over time
• Gain actionable molecular insights that may guide therapy selection
• Improve patient monitoring during and after treatment

These insights underscore the growing importance of precision diagnostics as part of a comprehensive CNS cancer care strategy.

How CNSide® Supports Clinical Decision-Making

The CNSide® CSF Assay Platform is engineered to provide:

• Accurate tumor cell enumeration to assess disease load
• Detailed molecular characterization to inform therapeutic options
• Reliable sample preservation using CEE-Sure™ CSF Collection Tubes
• Actionable, clinician-ready reports that translate complex data into clear insights
