2020-07-30 · The authors concluded that increasing millimeter thickness of uveal melanoma was associated with increasing risk for metastasis. Clinical factors predictive of metastasis by multivariate analysis included increasing patient age, ciliary body location, increasing tumor diameter, increasing tumor thickness, tumor pigmentation, and subretinal fluid, intraocular hemorrhage, and extraocular extension.
The most common site of metastasis for uveal melanoma is the liver; the liver is the first site of metastasis for 80%-90% of ocular melanoma patients. Other common sites of metastasis include the lung, bones, and just beneath the skin (subcutaneous).
Uveal melanoma accounts for 85% of the ocular melanomas and has an increased risk of hematogenous spread, most commonly to the liver. After curative intent therapy like surgery and radiation, fifty percent of patients present with distant metastasis. Metastatic uveal melanoma (MUM) does not harbor typically targetable mutations, e.g., BRAF as in cutaneous melanoma. Uveal melanoma (UM) is the most frequently found primary intra-ocular tumor in adults. It is a highly aggressive cancer that causes metastasis-related mortality in up to half of the patients. The cause of uveal melanoma is unclear. Uveal nevi are common (5% of Caucasians), but rarely progress to melanoma.
Whole-body screening catches uveal melanoma metastasis. Whole-body screening catches uveal melanoma metastasis. Article: Ocular melanoma represents a small subset of total melanoma cases. Approximately 3.7% of melanoma cases are ocular, 1 and slightly over 80% of ocular melanomas are classified as uveal. 1,2 Most uveal melanomas occur from the choroid, with the remainder developing from the ciliary body or iris. 1 The rate of ocular melanoma is 8–10 times higher in white than black people, and it is About 100 new patients with metastatic uveal melanoma have been seen every year since 1999. Despite successful treatment of primary uveal melanoma, up to 50 percent will develop a systemic metastasis, and in 70 to 90 percent of those cases, the metastasis will be to the liver.
Uveal melanoma is the most prevalent primary intraocular malignant tumor in adults [1, 2].After initial diagnosis and treatment of the primary tumor, up to 50% of patients subsequently develop systemic metastasis [3, 4].
After curative intent therapy like surgery and radiation, fifty percent of patients present with distant metastasis. Metastatic uveal melanoma (MUM) does not harbor typically targetable mutations, e.g., BRAF as in cutaneous melanoma.
Bilateral uveal melanoma is rare, with an estimated lifetime prevalence of 1 in 50 million. 1 Unilateral multifocal uveal melanoma may be even more rare. 2 Most reported cases have occurred in the context of ocular or oculodermal melanocytosis, a predisposing factor for uveal melanoma. 3,4 In previously reported cases of multifocal uveal melanoma without such predisposing conditions or
In our cohort, elevated lactate dehydrogenase level (LDH) is an i … Abstract. Uveal melanoma represents ∼85% of all ocular melanomas and up to 50% of patients develop metastatic disease. Metastases are most frequently localised to the liver and, as few patients are candidates for potentially curative surgery, this is associated with a poor prognosis. There is currently little published evidence for the optimal management and treatment of metastatic uveal melanoma and the lack of effective therapies in this setting has led to the widespread use of systemic The cause of uveal melanoma is unclear. Uveal nevi are common (5% of Caucasians), but rarely progress to melanoma. Metastasis. Because there are no lymphatic channels to the uveal tract, metastasis occurs through local extension and/or blood-borne dissemination.
Uveal melanomas, albeit relatively uncommon in general, are the most common primary intraocular tumor in dogs and occur in dogs more than any other species.1,2 Uveal melanomas are considered benign in this species, although metastasis has rarely been reported.3-5 The term “melanocytoma” is typically reserved for benign melanocytic tumors and may be a more appropriate term when referring to
About 100 new patients with metastatic uveal melanoma have been seen every year since 1999. Despite successful treatment of primary uveal melanoma, up to 50 percent will develop a systemic metastasis, and in 70 to 90 percent of those cases, the metastasis will be to the liver.

Its incidence in the United States is 5.2 cases per 1 million population per year. Roughly half of patients develop metastatic disease. 2020-02-10 · Uveal melanoma (UM) is the most common primary eye malignancy in adults and up to 50% of patients subsequently develop systemic metastasis.
The liver may be the only metastatic site even though lung, bone and skin metastases can also form. Se hela listan på radiopaedia.org
Thyroid metastasis is a rare occurrence with cutaneous melanoma and even more uncommon with uveal melanoma.

The connection of BAP1 loss to uveal melanoma metastasis has been reinforced by multiple independent studies. 49, 50 This also raised the possibility of targeting deubiquitinating enzymes in uveal melanoma. 49 Subsequently, more germline mutations of BAP1 have been described in patients with uveal melanoma, suggesting that BAP1 screening can identify individuals who have a predisposition to
