SWEPT-SOURCE OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY IN CHOROIDAL MELANOMA: An Analysis of 22 Consecutive Cases

Conclusion: Swept-source optical coherence tomography angiography represents a valid imaging technique to evaluate patients affected by choroidal melanomas. In our series, SS-OCT-A disclosed the intrinsic microvasculature of the tumor in all cases despite their size, location, and history of previous treatments.

In the era of precision oncology, major strides are being made to use individual tumor information for clinical decision-making. Differing from traditional biopsy methods, the emerging practice of liquid biopsy provides a minimally invasive way of obtaining tumor cells and derived molecules. Liquid biopsy provides a means to detect and monitor disease progression, recurrence, and treatment response in a noninvasive way, and to potentially complement classical biopsy. Uveal melanoma (UM) is a unique malignancy, with diagnosis heavily reliant on imaging, few repeat biopsies, and a high rate of metastasis, which occurs hemato...

ysegül Tura The prolonged storage of glucose as glycogen can promote the quiescence of tumor cells, whereas the accumulation of an aberrant form of glycogen without the primer protein glycogenin can induce the metabolic switch towards a glycolytic phenotype. Here, we analyzed the expression of n = 67 genes involved in glycogen metabolism on the uveal melanoma (UM) cohort of the Cancer Genome Atlas (TCGA) study and validated the differentially expressed genes in an independent cohort. We also evaluated the glycogen levels with regard to the prognostic factors via a differential periodic acid-Schiff (PAS) staining. ...

AbstractPurpose of ReviewUveal melanoma is a distinct subtype of melanoma characterized by a unique biology and divergent response to immune therapies. In this review, we will discuss our current understanding of the pathophysiology of uveal melanoma, systemic treatment options for advanced disease, and potential future therapeutic directions.Recent FindingsAlthough treatment with single-agent checkpoint blockade has been generally disappointing, the results of combined checkpoint blockade are modestly more promising. Several alternative systemic therapeutic approaches have been or are currently being investigated, includi...

CONCLUSION AND IMPORTANCE: Optic nerve invasion in uveal melanoma may lead to neurotropic spread of melanoma cells with risk of intracranial and spinal cord metastasis. Neurological symptoms should raise the suspicion of clinicians regarding this complication, which is associated with increased melanoma-related mortality.

Contributor : Peiwei ChaiSeries Type : Genome binding/occupancy profiling by high throughput sequencingOrganism : Homo sapiensWe identified aberrant CTCF binding lead to a 3D chromosomal interactional driver in NTS locus that accelerates tumorigenesis of uveal melanoma. Both enhancer deletion and abolishing CTCF binding lead to the loss of chromosomal looping and triggered therapeutic efficacy in inhibiting tumorigenesis. Our study shed light on a functional chromosomal architecture induced enhancer hijacking, thereby provide novel concept of 3D-chromosomal conformation exploration.

AbstractBiological understanding of pigmentation and its association with clinicopathological implications in uveal melanoma (UM) risk is still unexplored. HECT and RLD Domain Containing E3 Ubiquitin Protein Ligase 2 (HERC2) and Pink-eyed dilution protein (P-protein) are the important markers that regulate pigmentation in eye. Therefore, our aim of the study was to investigate the expression of HERC2 and P-protein in the UM patients and correlate with patient outcome. Fifty-two formalin-fixed paraffin-embedded UM tissue samples were included to detect the expression of HERC2 and P-protein by immunohistochemistry and valida...
