Is choroidal melanoma hereditary?


Is eye melanoma hereditary?

Intraocular melanoma can run in families, although it is rare. Usually, it is due to a mutation or change in a gene called BAP1, which is mostly linked with metastatic uveal eye cancer. This gene change is also seen in other cancer types, such as kidney cancer and mesothelioma.

How common is choroidal melanoma?

Choroidal melanomas are relatively rare, with an incidence of approximately five to six cases per one million people, which equates to about 1,400 cases in the United States each year.

What causes choroidal melanoma?

Evidence points to sunlight exposure as a likely contributor to the development of choroidal melanoma. Predisposing diseases for uveal melanomas include a family history of uveal melanoma, uveal nevus, congenital ocular melanocytosis, dysplastic nevus syndrome, and xeroderma pigmentosum.

Is choroidal melanoma fatal?

The tumors also can spread (metastasize) to other parts of the body. The liver is the most common site for metastasis. If it spreads, this cancer can be fatal.

Is ocular melanoma a death sentence?

“Overall, melanoma of the eye spreads and leads to death in approximately 30% to 50% of patients,” she said. “When it spreads it most often enjoys living in the liver and the lungs. And once it spreads, the life survival is under 1 year.

How long does it take for eye melanoma to spread?

Based on the aggressiveness of the particular tumor, as defined by clinical and genetic features, metastasis may be detected as early as 2-3 after diagnosis and rarely as late as decades after treatment.

Can choroidal melanoma be cured?

Even though the melanoma is cured and in remission in the eye, life-long systemic monitoring for metastasis is necessary, as metastasis could have occurred before the eye cancer was discovered.

How long does it take choroidal melanoma to spread?

The median time from diagnosis of choroidal melanoma to diagnosis of metastasis was 44.8 months (3.7 years).

Can choroidal melanoma spread?

Choroidal Melanoma is the most common primary intraocular malignant tumor and the second most common intraocular tumor, behind metastases. It is estimated that up to 50% of patients with choroidal melanoma develop metastatic disease, despite successful treatment of the primary tumor.

How aggressive is ocular melanoma?

This is an aggressive type of cancer that can potentially spread to other areas of the body, most often to the liver. Immediate treatment is often necessary. The approach depends on the size and placement of the tumor, and the stage at which it is found. The two most common treatments are radiation therapy and surgery.

What is the prognosis for melanoma of the eye?

The 5-year survival rate for eye melanoma is 82%. When melanoma does not spread outside the eye, the 5-year relative survival rate is about 85%. The 5-year survival rate for those with disease that has spread to surrounding tissues or organs and/or the regional lymph nodes is 71%.
