Data from 1,868 Surveillance, Epidemiology and End Results (SEER)-linked patients show DecisionDx-Melanoma significantly stratifies five-year melanoma-specific survival within American Joint Committee on Cancer (AJCC) stages and T categories, identifying patients whose mortality risk is substantially higher or lower than staging alone would predict FRIENDSWOOD, Texas, March 27, 2026 /PRNewswire/ -- Castle Biosciences, Inc. (Nasdaq: CSTL), a company improving health through innovative tests that guide patient care, will present new data at the 2026 American Academy of Dermatology (AAD) Annual Meeting, taking place March 27–31 in Denver, demonstrating that its DecisionDx-Melanoma test refines mortality risk within AJCC stages for patients with cutaneous melanoma (CM). The data show that DecisionDx-Melanoma identifies clinically meaningful differences in mortality risk among patients within the same stage, which may help clinicians more confidently escalate care for higher-risk patients while avoiding unnecessary interventions in those at lower risk of poor outcomes.
