ConclusionOur data showed that non-canonical NF κB proteins were significantly higher in metastatic cases and associated with poor outcome of the patients. Furthermore, the p52 protein could be used as a potential therapeutic biomarker for metastatic cases in uveal melanoma.

We examined these patterns with digital image analysis and transmission electron microscopy, and correlated them with BAP-1 expression, gene expression class, macrophage infiltration, and metastatic disease in full tumor cross-sections and intratumor regions. Methods: Thirty-two enucleated eyes with UM were stained immunohistochemically (BAP-1, laminin, CD31, and CD68) and with PAS without hematoxylin counterstain. Retrospective data on gene expression class and patient survival were retrieved. Tumor sections were digitally scanned and analyzed with the QuPath Bioimage analysis software, and imaged with transmission el...

ConclusionsCollectively our data suggest that a nonselective beta ‐blocker may be effective against melanoma. For the first time, we show potent anti‐tumor effects in UM cells following propranolol administration and expression of β1 and β2 adrenoceptors in patient tissue.

Kiilgaard Donia Svane Uveal melanoma (UM) is the most common intraocular malignancy in adults and shows a high rate of metastatic spread. As randomized clinical trials with immune checkpoint inhibitors (ICI) have not been performed in patients with metastatic UM, we analyzed the real-world outcomes in a nationwide population-based study. Clinical data of patients with UM were extracted from the Danish Metastatic Melanoma database, a nationwide database containing unselected records of patients diagnosed with metastatic melanoma in Denmark. Survival before (pre-ICI, n = 32) and after (post-ICI, n = 94) the appro...

AbstractBackgroundUveal melanoma (UM) is a rare cancer that arises from melanocytes in the uveal tract of the eye. Despite effective treatment for primary UM,> 50% of patients develop metastatic disease. There is currently no effective treatment for metastatic UM and median life expectancy is

ConclusionsThe PEMDAC study has demonstrated that combined HDAC- and PD-1-inhibition can result in clinical efficacy in metastatic uveal melanoma with manageable toxicities. The obtained data warrant further investigation to address clinical and immunological characteristics of patients achieving clinical benefit.Clinical trial identificationNCT02697630 (Registered 3 March 2016).

ConclusionsTreatment with MART-1 TCR transduced peripheral blood T cells expanded in presence of IL-7 and IL-15 led to severe dose-dependent toxicity with a maximum tolerated dose of 10 x 107 transduced cells. Despite observed responses, toxicity limited further development and use of this MART-1 TCR cellular therapy in MM patients.

In this study, we found that: (a) high expression of lncRNAMIR155 host gene (MIR155HG) was closely related to better overall survival (OS) in cholangiocarcinoma (CHOL), lung adenocarcinoma (LUAD), and skin cutaneous melanoma (SKCM), and have better disease ‐free survival (DFS) in CHOL. Meanwhile, the high level ofMIR155HG was associated with poorer OS in glioblastoma multiforme (GBM), kidney renal clear cell carcinoma (KIRC), brain lower grade glioma (LGG), and uveal melanoma (UVM). (b) The expression ofMIR155HG was significantly correlated with infiltrating levels of immune cells and immune molecules, especially with im...

Publication date: Available online 26 September 2019Source: Progress in Retinal and Eye ResearchAuthor(s): Kyra N. Smit, Martine J. Jager, Annelies de Klein, Emine KiliҫAbstractUveal melanoma is an aggressive malignancy that originates from melanocytes in the eye. Even if the primary tumor has been successfully treated with radiation or surgery, up to half of all UM patients will eventually develop metastatic disease. Despite the common origin from neural crest-derived cells, uveal and cutaneous melanoma have few overlapping genetic signatures and uveal melanoma has been shown to have a lower mutational burden. As a conse...
