Second Primary Neoplasms in Patients With Uveal Melanoma: A SEER Database Analysis [PDF]
American Journal of Ophthalmology, 2016 To determine the risk of second primary neoplasms (SPNs) in subjects previously diagnosed with uveal melanoma (UM), including an analysis on whether radiotherapy is a risk factor to develop these SPNs.Retrospective cohort study.Using the Surveillance, Epidemiology, and End Results (SEER) 9 database, we identified patients diagnosed with UM as their ...

SF3B1 and EIF1AX mutations occur in primary leptomeningeal melanocytic neoplasms; yet another similarity to uveal melanomas [PDF]
Acta Neuropathologica Communications, 2016 Like uveal melanomas, primary leptomeningeal melanocytic neoplasms (LMNs) frequently carry GNAQ and GNA11 mutations. However, it is currently unknown whether these LMNs harbor mutations in BAP1, SF3B1 and/or EIF1AX like uveal melanomas as well. In this study, we used Sanger sequencing for the detection of mutations in SF3B1 (hotspots in exon 14 and 15)

Investigative Opthalmology & Visual Science, 2017 Adenocarcinomas or adenomas derived from pigmented ciliary epithelium (APCE) are exceptionally rare ocular tumors. These tumors have pigmented and epithelioid features, and some APCEs are negative for keratin markers and positive for melanocytic markers. It is especially difficult to distinguish APCEs from uveal melanoma (UM).

Expression of cyclooxygenase-2 in canine uveal melanocytic neoplasms
American Journal of Veterinary Research, 2009 Abstract Objective—To determine whether cyclooxygenase-2 (COX-2) is expressed in benign or malignant canine uveal melanocytic neoplasms and whether expression correlates with malignancy. Sample Population—Tissue sections from 71 globes; 57 with benign (n = 15), malignant (34), or mixed (8) uveal melanocytic neoplasms; 10 with nonneoplastic disease; and

Immunoexpression of Macroh2a in Uveal Melanoma
Applied Sciences, 2019 MacroH2A is a histone variant whose expression has been studied in several neoplasms, including cutaneous melanomas (CMs). In the literature, it has been demonstrated that macroH2A.1 levels gradually decrease during CM progression, and a high expression ...
