Five Decades of Enucleations for Uveal Melanoma in One Center: More Tumors with High Risk Factors, No Improvement in Survival over Time.

Ocul Oncol Pathol 2021 Mar 15;7(2):133-141. Epub 2020 Dec 15.

Department of Ophthalmology, Leiden University Medical Center, Leiden, The Netherlands.

Background: In order to improve medical care for uveal melanoma (UM) patients, we need to monitor disease and survival to guide our research efforts. We analyzed the data of UM patients who underwent an enucleation at the Leiden University Medical Center over the last five decades and investigated trends in patient and tumor characteristics and survival.

Methods: Data were collected from charts and pathology reports from all patients who underwent an enucleation for UM between 1973 and 2019 ( = 1,212), of which 1,066 were primary enucleations; data were analyzed according to five time periods: 1973-1979 ( = 209), 1980-1989 ( = 148), 1990-1999 ( = 174), 2000-2009 ( = 280), and 2010-2019 ( = 401).

Eye Tumors in Childhood as First Sign of Tumor Predisposition Syndromes: Insights from an Observational Study Conducted in Germany and Austria.

Cancers (Basel) 2021 Apr 14;13(8). Epub 2021 Apr 14.

Institute of Human Genetics, Medical Faculty, University Duisburg-Essen, 45122 Essen, Germany.

Retinoblastoma and other eye tumors in childhood are rare diseases.

Rapid growth of primary uveal melanoma following intravitreal bevacizumab injection: a case report and review of the literature.

Digit J Ophthalmol 2021 Feb 3;26(3):27-30. Epub 2020 Jul 3.

Department of Ophthalmology and Visual Sciences, University of Alberta, Edmonton, Alberta, Canada.

Uveal melanoma size is a significant predictor of tumor metastasis. Although the relationship between antivascular endothelial growth factors (VEGF) and uveal melanoma growth has been studied, results are paradoxical, and the relationship remains controversial. We report the case of a 65-year-old man who presented with elevated intraocular pressure in his right eye, neovascularization of his iris, and significant corneal edema, which obscured the view of the angle.

Update on uveal melanoma: Translational research from biology to clinical practice (Review).

Int J Oncol 2020 Dec 22;57(6):1262-1279. Epub 2020 Oct 22.

Department of Surgery, Medical and Social Sciences, Faculty of Medicine and Health Sciences, University of Alcalá, Alcalá de Henares, 28871 Madrid, Spain.

Uveal melanoma is the most common type of intraocular cancer with a low mean annual incidence of 5‑10 cases per million. Tumours are located in the choroid (90%), ciliary body (6%) or iris (4%) and of 85% are primary tumours. As in cutaneous melanoma, tumours arise in melanocytes; however, the characteristics of uveal melanoma differ, accounting for 3‑5% of melanocytic cancers. Read More
