Prospecive validation of the i31-GEP for cutaneous melanoma to select patients who may consider foregoing SLNB
Mar 2024
This study shares three-year outcomes data from Castle’s prospective, multicenter study of patients with melanoma who were being considered for an SLNB (n=322). In the study, at three years, all patients with a low-risk DecisionDx-Melanoma test result were recurrence free (recurrence free survival of 100%). The performance data shared in this presentation, in conjunction with previous validation and performance studies, show DecisionDx-Melanoma as an accurate and precise clinical tool that can identify patients who may safely forego SLNB, reducing the number of unnecessary SLNBs performed (by ~25% in this study alone) and the associated costs and risks of complications that accompany them.

The 31-gene expression profile test outperforms AJCC in stratifying risk of recurrence in patients with stage I cutaneous melanoma
Jan 2024
In a head-to-head comparison of DecisionDx-Melanoma to AJCCv8 staging for stage I cutaneous melanoma (CM) patients (n=6,883) two cohorts were analyzed using recurrence-free survival and melanoma-specific survival. Results from the study showed that DecisionDx-Melanoma significantly improved patient risk stratification, independent of AJCC staging in patients. In addition, DecisionDx-Melanoma provided greater separation between high-risk (Class 2B) and low-risk (Class 1A) groups than seen between AJCC stage IA and IB.
