Among a cohort of Asian patients with uveal melanoma, their largest tumor basal diameter is most strongly associated with risk for metastasis and metastasis-related death, according to research results In uveal melanoma the most common site of metastatic disease is the liver, and a number of hepatic-directed therapies are available including surgery, radiofrequency ablation, and embolization. Conventional systemic chemotherapy has shown poor response rates in uveal melanoma. 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.

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. The baseline characteristics of the primary uveal melanoma were not associated with survival in patients with stage IV disease.

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. Metastasis. Because there are no lymphatic channels to the uveal tract, metastasis occurs through local extension and/or blood-borne dissemination.

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 Metastasis of uveal melanoma preferentially develops in the liver and is thought to be driven by high levels of growth factors such as epidermal-, insulin-like-, and hepatic growth factors .

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. Many independent studies have reported somatic genetic changes associated with high metastatic risk, such as monosomy of chromosome 3 and mutations in BAP1. Still, the mechanisms that drive metastatic

Uveal melanomas metastasize through the blood circulation, almost always to the liver. Such ‘metastatic disease’ develops almost exclusively in patients whose tumor shows particular genetic abnormalities, such as loss of chromosome 3 (‘monosomy 3’), BAP1 deletion, and a class 2 gene expression profile.

In a great number of patients with uveal melanoma, metastatic disease is not detected at diagnosis. Up to 50% of patients develop metastatic disease at any time from the initial UM diagnosis to several decades later. 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 management of such metastasis is uncertain due to its infrequency and, in the era of immunotherapy, the effect of these novel drugs on uncommon metastasis, such as to the thyroid, is unknown.
