New data from Mayo Clinic researchers presented at DDW 2026 demonstrates that Castle Biosciences' TissueCypher test improves risk stratification for Barrett's esophagus compared to standard histopathology. One study found physicians modified surveillance intervals in 55% of patients based on TissueCypher results, while a second study showed the test classified 84% of patients as low risk versus just 38% for the standard PIB model.
