Next-generation sequencing of uveal melanoma for detection of genetic alterations predicting metastasis
Apr 2019
Purpose: To clinically use the UCSF500, a pancancer, next-generation sequencing assay in uveal melanoma (UM) and to correlate results with gene expression profiling (GEP) and predictive factors for metastasis.

Identification of patients at risk of metastasis using a prognostic 31-gene expression profile in subpopulations of melanoma patients with favorable outcomes by standard criteria
Jan 2019
Discovery of reduced RFS for patients with thin tumors and Class 2B biology and cumulative validation cohort for DecisionDx-Melanoma. DecisionDx-Melanoma was the strongest independent predictor of RFS, DMFS and MSS.

Estimation of prognosis in invasive cutaneous melanoma: an independent study of the accuracy of a gene expression profile test
Dec 2018
Independent study of the predictive accuracy of the GEP test, to determine what clinical and histopathologic features predict high-risk classification, and to evaluate how intermediate classes (1B & 2A) performed clinically. Patients with GEP Class 2 result were 22 times more likely to metastasize compared to a Class 1 result.

Gene expression profiling and PRAME status versus tumor-node-metastasis staging for prognostication in uveal melanoma
Aug 2018
To compare the prognostic accuracy of gene expression profiling (GEP) combined with PRAME status versus the clinical Tumor-Node-Metastasis (TNM) staging in patients with uveal melanoma (UM).
