Spots Global Cancer Trial Database for The Role of Genetic Mutations and of Circulating mRNAs in Uveal Melanoma

Study Description

Brief Summary: The aim of the study is to identify genetic and epigenetic biomarkers in uveal melanoma, and to evaluate their diagnostic and prognostic role. In particular, the specific objectives are: 1. to identify the circulating somatic mutations associated with uveal melanoma; 2. to identify the de-regulated miRNAs associated with uveal melanoma; 3. to evaluate the diagnostic and prognostic role of the identified genetic and epigenetic markers; 4. to identify possible therapeutic targets.

Detailed Description: This is a prospective, multicentric, case-control study, aimed at studying the gene and epigenetic mechanisms involved in uveal melanoma. Patients with uveal melanoma, will be enrolled. For each subject included in the study, in a blood sample will be searched the mutations of the GNA11 and GNAQ genes and the expression of the following microRNAs: miR - 506-514 cluster, hsamiR - 592 and hsa - miR - 199a - 5p; the digital PCR droplet system will be used. The study will not change the diagnostic-therapeutic process adopted in the clinical practice and will have no influence on the clinical management of enrolled patients. A group of age sex matched controls will be recruited among patients scheduled for cataract surgery. The sample size was calculated to detect, with a power of 80% and a confidence interval of 95%, a difference of 13.5% between the incidence of mutation of the GNA11 gene in patients with melanoma and healthy controls. (13.5% vs 0%). Overall, at least 51 patients with uveal melanoma and 51 controls will be recruited, for a total of at least 102 subjects.
