MCED Blood Test Detects Cancer Early With High Accuracy


Nima Nabavizadeh, MD, Oregon Health & Science University, Portland, Oregon, discusses results from the registrational phase 2 PATHFINDER-2 study evaluating an MCED multi-cancer early detection blood test in an intended-use population.

Results showed that the test safely increased the number of screen-detected cancers more than sevenfold, achieved a 62% positive predictive value, and accurately predicted cancer signal origin in most cases, underscoring its potential to advance population-wide early cancer detection.

These results were presented at the 2025 European Society for Medical Oncology (ESMO) Congress in Berlin, Germany.
