PURPOSE To screen the microarray expression of CDH1, ECM1, EIF1B, FXR1, HTR2B, ID2, LMCD1, LTA4H, MTUS1, RAB31, ROBO1, and SATB1 genes which are predictive of primary uveal melanoma metastasis, and NFKB2, PTPN18, MTSS1, GADD45B, SNCG, HHIP, IL12B, CDK4, RPLP0, RPS17, RPS12 genes that are differentially expressed in metastatic uveal melanoma in normal whole human blood and tissues prone to metas...

PURPOSE The purpose of this study was to determine the susceptibility of human uveal melanoma cells to in vitro and in vivo natural killer (NK) cell-mediated cytolysis and to determine if NK cells influence metastasis from the eye. METHODS Four human uveal melanoma cell lines and one melanoma cell line derived from a metastatic lesion from a patient with uveal melanoma were tested for in vitr...

PURPOSE To develop a method to screen for serum biomarkers of early hepatic metastasis from uveal melanoma. METHODS Cytokeratin 18 (TPS) was identified from gene expression profiles as protein generated by highly invasive uveal melanoma cells. Sera were collected from two groups of 15 SCID mice 2 weeks after injection of either tissue culture medium or MUM2B human metastatic uveal melanoma ce...

OBJECTIVE The objective of this study was to evaluate the correlation between the expression of p53 gene and the prognosis after local excision in uveal melanoma. MATERIALS AND METHODS Real-time polymerase chain reaction (RT-PCR) test and Western blot were used to detect the expression of p53 in C918, MUM-2B, and D78 cell lines at the levels of messenger RNA (mRNA) and protein. Immunohistoche...

BACKGROUND AND PURPOSE The aim of this study was to establish the MR imaging characteristics of choroidal hemangioma and to compare them with those of uveal melanoma. METHODS Among 41 patients examined at 1.5 T (4-cm surface coil, T1-weighted and fast spin-echo T2-weighted sequences), 25 had uveal melanoma and 16 had circumscribed choroidal hemangioma. After i.v. bolus injection of gadopentet...

PURPOSE To evaluate the clinical significance of 5-S-cysteinyldopa (5-S-CD), a major intermediate in melanin synthesis, as a potential diagnostic tumor marker for uveal malignant melanoma. METHODS The levels of 5-S-CD in the serum were measured by high-performance liquid chromatography in 16 patients with primary uveal melanoma. The levels of 5-S-CD were also measured in both aqueous and vitr...

background: recent studies in eye plaque brachytherapy have shown a considerable difference between the dosimetric results using water phantom and a model of human eye containing realistic materials. in spite of this fact, there is a lack of simulation studies based on such a model in proton therapy literatures. in the presented work, the effect of utilizing an eye model with ocular media on pr...

Uveal melanoma is the most common primary intraocular malignant tumor in adults and half of the primary tumors will develop fatal metastatic disease to the liver and the lung. Crizotinib, an inhibitor of c-Met, anaplastic lymphoma kinase (ALK), and ROS1, inhibited the phosphorylation of the c-Met receptor but not of ALK or ROS1 in uveal melanoma cells and tumor tissue. Consequently, migration o...

BACKGROUND Uveal melanoma is the most common primary intraocular tumor in adults. In the last two decades the Hadassah-Hebrew University Medical Center ocular oncology clinic has become a referral center for uveal melanoma patients. OBJECTIVES To describe the characteristics of uveal melanoma patients in Israel, their treatment modalities and outcomes during the years 1988-2007. METHODS Dat...

OBJECTIVE To review the evidence for molecular genetic testing of uveal melanoma in the context of prognostic indicators of metastasis and tumour-related mortality. DESIGN Review of the literature and personal experiences of the authors. METHODS We conducted a MEDLINE, Embase, and PubMed literature search (1980-2011) for English-language abstracts and full-text references regarding molecula...
