Utility of 31-gene expression profile test in identifying patients with T1 cutaneous melanoma at high risk of SLN positivity and recurrence
Mar 2024
Demonstrate that the 31-GEP offers significant prognostic value in addition to SLN status to help identify patients at the highest risk of tumor recurrence.

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.

An Automated Tissue Systems Pathology Test Can Standardize the Management and Improve Health Outcomes for Patients with Barrett's Esophagus
Nov 2023
Management guided by the TissueCypher test can standardize care plans by increasing the early detection of progressors who can receive therapeutic interventions, while also increasing the percentage of nonprogressors who can avoid unnecessary therapy and be managed by surveillance alone.
