Five Year Study to Track Use of DecisionDX-Melanoma Test in Patients With Cutaneous Melanoma and Associated Patient Outcomes (EXPAND)

October 1, 2021 updated by: Castle Biosciences Incorporated

An Open, 5-year Registry Study to Track Clinical Application of DecisionDx-Melanoma Gene Expression Profile Assay Results and Associated Patient Outcomes

The EXPAND Registry Study follows patients with cutaneous melanoma who have had the DecisionDx-Melanoma gene expression assay performed as part of their clinical care. Data will be collected through review of medical records from clinical visits with physician.

The purpose is to document the clinical application of results obtained from the DecisionDx- Melanoma multi-gene assay and to track outcomes of patients for whom DecisionDx-Melanoma testing has been completed. Additionally the study will assess the health economic impact of DecisionDx-Melanoma testing as it relates to the Melanoma population.
