GRAIL's Galleri Test Enhances Early Cancer Detection at ASCO Meeting
GRAIL, Inc. has presented the results of its PATHFINDER 2 study at the 2026 American Society of Clinical Oncology (ASCO) Annual Meeting. The study involved 35,878 participants and evaluated the Galleri multi-cancer early detection (MCED) test. The test screens for over 50 types of cancer, including those without current screening options, such as pancreatic and ovarian cancers. The Galleri test demonstrated a 6.5-fold increase in cancer detection when added to standard screenings for breast, colorectal, cervical, and lung cancers. Notably, 71% of the new cancers detected were in stages I-III, allowing for potentially curative treatments. The test also showed a low false positive rate and high accuracy in predicting the cancer signal origin, facilitating efficient diagnostic evaluations.
