The two most common treatments are radiation therapy and surgery. Depending on the size and placement of the tumor, vision may be preserved. In advanced cases, aggressive treatment may be necessary, and vision is lost. When an eye must be removed, patients can opt for reconstructive surgery, including the use of an artificial eye, or prosthesis.
What are the prognosis and treatment options for melanoma of the eye?
The prognosis (chance of recovery) and treatment options depend on the following: How the melanoma cells look under a microscope. The size and thickness of the tumor. The part of the eye the tumor is in (the iris, ciliary body, or choroid). Whether the tumor has spread within the eye or to other places in the body.
What is melanoma and how is it treated?
Melanoma is the deadliest form of skin cancer. In the early stages, melanoma can be treated successfully with surgery alone and survival rates are high, but after metastasis survival rates drop significantly. Therefore, early and correct diagnosis is key for ensuring patients have the best possible prognosis.
What is the best treatment for cancer in the eye?
Radiation offers the best chance of preserving vision in the eye, but some people who have radiation may eventually need surgery, too. Large melanomas: The standard treatment for these cancers is usually radiation. Proton beam therapy and stereotactic radiation therapy are usually used first.
What are the treatment options for ciliary body melanoma?
Ciliary body melanomas. These rare cancers can be treated with either surgical removal of the tumor, if it is small enough, or radiation therapy. In more advanced cases or if there is serious eye damage, enucleation (removal of the eyeball) may be needed.
What is the life expectancy of someone with metastatic ocular melanoma?
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%.
Is aggressive melanoma treatable?
Treatment for early-stage melanomas usually includes surgery to remove the melanoma. A very thin melanoma may be removed entirely during the biopsy and require no further treatment. Otherwise, your surgeon will remove the cancer as well as a border of normal skin and a layer of tissue beneath the skin.
How aggressive is ocular melanoma?
Although rare, melanomas of the conjunctiva tend to be more aggressive than most uveal melanomas. They are more likely to grow into local structures and spread to distant organs like the liver and lungs where the situation can become life-threatening.
Is ocular melanoma a death sentence?
Choroidal melanoma is a disease with a high mortality rate, usually irrespective of the chosen treatment modality. About 30-50% of patients with choroidal melanoma will die within 10 years from diagnosis and treatment. Death is usually secondary to distant metastases, and the risk is greatest in larger tumors.
What is aggressive melanoma?
Nodular melanoma is a type of skin cancer. It is the most aggressive form of melanoma because it grows and spreads quickly and can often go unnoticed.
How successful is immunotherapy for melanoma?

How are the stages of melanoma assigned?
Melanoma stages are assigned using the TNM system. The stage of the disease indicates how much the cancer has progressed by taking into account the size of the tumor, whether it’s spread to lymph nodes, and whether it’s spread to other parts of the body.
What is stage 0 melanoma?
Stage 0 melanoma is also called melanoma in situ. This means that your body has some abnormal melanocytes. Melanocytes are the cells that produce melanin, which is the substance that adds pigment to the skin. At this point, the cells could become cancerous, but they’re simply abnormal cells in the top layer of your skin.
What is the name of the cancer that starts as a dark mole on the skin?
Melanoma is a kind of cancer that begins in the skin cells that create the pigment melanin. Melanoma usually starts as a dark mole on the skin. However, it can also form in other tissue, such as the eye or mouth. It’s important to keep an eye on moles and changes in your skin, as melanoma can be deadly if it spreads.
How do doctors diagnose melanoma?
A doctor can identify a possible melanoma during a physical exam and confirm the diagnosis with a biopsy, where the tissue is removed to determine if it’s cancerous. But more sophisticated technology, such as PET scans and sentinel lymph node biopsies, are necessary to determine the cancer’s stage or how far it’s progressed.
How thick is a stage 1 tumor?
Stage 1. In stage , the tumor is up to 2 mm thick. It may or may be ulcerated, which indicates whether the tumor has broken through the skin. The cancer has not spread to nearby lymph nodes or to distant parts of the body. For stage 0 and stage 1, surgery is the main treatment.

If there's a risk that the cancer has spread to the lymph nodes, your doctor may recommend a procedure known as a sentinel node biopsy. During a sentinel node biopsy, a dye is injected in the area where your melanoma was removed. The dye flows to the nearby lymph nodes.
What is the stage of melanoma?
Melanoma is staged using the Roman numerals 0 through IV. At stage 0 and stage I, a melanoma is small and has a very successful treatment rate. But the higher the numeral, the lower the chances of a full recovery. By stage IV, the cancer has spread beyond your skin to other organs, such as your lungs or liver.
How does thickness affect melanoma?
The thickness of a melanoma helps doctors decide on a treatment plan. In general, the thicker the tumor, the more serious the disease. Thinner melanomas may only require surgery to remove the cancer and some normal tissue around it.

ABSTRACT
Melanoma is the deadliest form of skin cancer. In the early stages, melanoma can be treated successfully with surgery alone and survival rates are high, but after metastasis survival rates drop significantly. Therefore, early and correct diagnosis is key for ensuring patients have the best possible prognosis.
Introduction
At the basal level of the epidermis sit the melanocytes, which produce the UV absorbing pigment melanin. Melanocytes make up a minority cell population in the epidermis, with only 1500 melanocytes per square millimeter, and divide infrequently, less than twice per year.
History of melanoma
Melanoma is generally thought of as a modern disease exacerbated by migration of fair skinned people to areas nearer the equator and by modern sun-seeking behavior. However, although melanoma incidence rates have certainly skyrocketed in modern times, melanoma is an ancient disease that has been documented throughout history.
Molecular defects
When melanoma was first recognized as a disease in the 1800s it was classified based on where the tumor arose. In the 1960s melanomas began to be classified based on histologic patterns.
Diagnosis and prognosis of melanoma
The early classification of melanoma was based on where the tumor arose from (existing nevus, acquired melanocytic lesion, blemish free skin), but in the 1960s a prominent dermatologist, Wallace Clark, suggested that melanoma ought to be classified based on histological features instead, thus revolutionizing the way melanoma was diagnosed.
Treatment
Surgical removal of the tumor and surrounding healthy tissue is the primary treatment for localized melanoma, and sentinel lymph node biopsy is performed in patients whose tumors are greater than 0.8 mm thick or are thinner than this but ulcerated (stage pT1b or greater).
Conclusion
Melanoma is an incredibly virulent disease. It is a heterogenous and complex disease, which can make it difficult to diagnose and treat. Understanding the mechanisms that lead to melanomagenesis and allow melanomas to evade the immune system will give us new strategies for diagnosis and treating the disease.
