Uveal melanoma metastasis

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. Metastatic uveal melanoma (MUM) is highly resistant to immunotherapy. One of the mechanisms for resistance would be the immune-suppressive tumor microenvironment. The mediansurvival of patients who first develop liver metastasis from uveal melanomais 5 to 7 months, as compared with 18 months for other initial sites of metastasis. 2-4 This poor prognosiscontinues despite treatment modalities such as chemoembolization.

The baseline characteristics of the primary uveal melanoma were not associated with survival in patients with stage IV disease. In the multivariate analysis, the following factors at first metastatic diagnosis were associated with improved overall survival: disease-free interval > 36 months; better performance status; and normal serum lactate dehydrogenase and gamma glutamyl transpeptidase levels.

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.

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. Patients with uveal melanoma metastatic to the liver who present without symptoms and receive local therapy as first-line treatment have longer progression-free survival (PFS) and overall survival (OS) than those who present with symptoms and receive other first-line therapies. Whole-body screening catches uveal melanoma metastasis.

Survival of patients following metastasis is poor at 6–12 months and the treatment of uveal melanoma has not benefited by the recent improvements for 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]. Diffuse melanoma is a variant of melanoma that exhibits horizontal growth pattern in a relatively flat configuration and displays a more aggressive course with invasion of the sclera, extrascleral extension, epithelioid cell type, and higher rate of metastasis. 14 In this analysis, diffuse melanoma represented 3% of all uveal melanoma, and Abstract.

Key words: eye, neoplasm, metastasis, melanoma. Uveal melanoma is the most common primary ocular malignancy in white people, accounting for 70% of all eye malignancies. It arises from the melanocytes in the uveal stroma.
