Metastatic prognosis in uveal melanoma is assessed by gene expression profiling (GEP) testing of the tumor cells, usually obtained by fine needle aspiration (FNA). GEP has demonstrated high accuracy in distinguishing class I and II tumors, both having different metastatic potential. Transcriptomic studies identified distinct mutations including somatic mutations in GNAQ and GNA11, detected in more than 80%, and contribute to the upregulation of the mitogen-activated protein kinase (MAPK…

Genetic analysis reveals wide diversity of melanoma of eye and is important for it characterization and treatment.


Oncogenic mutations in GNAQ occur early in uveal melanoma.
GNAQ mutations occur in about half of UMs, representing the most common known oncogenic mutation in this cancer, and provide new insights into UM pathogenesis and could lead to new therapeutic possibilities.
Biology of advanced uveal melanoma and next steps for clinical therapeutics
The current understanding of the molecular and immunobiology of uveal melanoma is reviewed, and on‐going laboratory research into the disease is highlighted, and recent investigations relevant to clinical management via targeted and immunotherpies are reviewed.
Mutational Profile of GNAQ Q209 in Human Tumors
The data indicate that the occurrence of GNAQ mutations display a unique pattern being present in a subset of melanocytic tumors but not in malignancies of glial, epithelial and stromal origin analyzed in this study.
Molecular Pathways Mediating Liver Metastasis in Patients with Uveal Melanoma
New insights are described into the genetic and molecular pathways that may play a role in the development of liver metastases in uveal melanoma patients.
A Case Study in Advanced Lung Cancer Patients with Vimentin Over Expression.
A case study of 12 patients with advanced lung cancer who had vimentin testing as a part of their work up over the past five years at the University of Cincinnati and found that this was correlated with overall survival of this group of patients.

Metastatic melanoma to the liver: A contemporary and comprehensive review of surgical, systemic, and regional therapeutic options
In conclusion, hepatic resection offers the possibility of long‐term survival in carefully selected patients with liver‐limited metastases from melanoma and in patients with unresectable cutaneous melanoma, effective systemic therapy is the best treatment option.
Nab-paclitaxel in patients with metastatic melanoma
The role of nab-paclitaxel in the management of patients with advanced melanoma is summarized, which shows it continues to play a role in the salvage treatment of patients that have become refractory to immune-based or targeted therapies.
Very long-term prognosis of patients with malignant uveal melanoma.
Investigating the very long-term prognosis of patients with uveal melanoma and the clinical characteristics influencing it found cumulative incidences provide a sound basis for patient counseling and design of trials.
