Prospective Evaluation of Risk-Appropriate Management of Uveal Melanoma Patients Informed by Gene Expression Profiling

AIM: The Clinical Application of DecisionDx-UM Gene Expression Assay Results study aimed to evaluate the clinical utility of the prognostic 15-gene expression profile (15-GEP) test for uveal melanoma (UM) patients in a large, prospective multicenter cohort. PATIENTS & METHODS: Nine centers prospectively enrolled 138 UM patients clinically tested with the 15-GEP. Physician-recommended specialty referrals and metastatic surveillance regimens were collected. RESULTS: A total of 93% of high-risk class 2 patients were referred to medical oncology for follow-up, compared with 51% of class 1 patients. A majority (62%) of class 2 patients were recommended overall high-intensity metastatic surveillance, while 85% of class 1 patients were recommended low-intensity metastatic surveillance. CONCLUSION: Treatment plan recommendations for UM patients are aligned with GEP-informed metastatic risk, consistent with prior studies.
