Cell-free DNA from Cerebrospinal Fluid for Diagnosis and Molecular Testing of Brain Tumors

Summary

October 9, 2025

While Cerebrospinal Fluid (CSF) cytology represents a long-established, routine test used for diagnosis, staging, and therapeutic decisions, Cell-free DNA (cfDNA) from CSF is rapidly emerging as a rich source for tumor characterization via liquid biopsies.

Join the Association for Molecular Pathology at 1 pm ET on October 9 for a live webinar that will cover:
  • The origin of cfDNA and biologic factors that may influence detection
  • Techniques for collection and extraction to optimize success
  • Assays that have demonstrated the use of cfDNA from CSF as a source material
  • How molecular testing of cfDNA from CSF is being integrated into clinical care
