Types of treatment for eye melanoma

• Surgery
• Radiation therapy

• Immunotherapy
• Targeted therapy

Surgery

Surgery may be done under a local anaesthetic with sedation or under a general anaesthetic. You may need to stay in hospital for a period of time.

What are the types of surgery for eye melanoma?

Radiation therapy

Radiation therapy uses high-energy rays to destroy cancer cells. It may be used:

• after surgery, to destroy any remaining cancer cells and stop the cancer coming back
• if the cancer can’t be removed with surgery
• instead of removing the eye (enucleation)
• if the cancer has spread to other parts of the body.

Radiation therapy doesn’t hurt and is given over a set time period. It’s given in different ways.

Plaque brachytherapy

A small disc (a plaque) containing radioactive material is put over the tumour during surgery. You may have a general anaesthetic (so you are asleep) or a local anaesthetic with sedation (so you are awake but relaxed and feel no pain). You stay in hospital for 2–7 days with the disc in place. Then you have a short operation to remove the disc and go home.

For more information, visit The Royal Victorian Eye and Ear Hospital to read their fact sheet on Plaque Radiotherapy.

Stereotactic radiation therapy

This uses radiation in the form of x-ray beams. A large machine directs multiple small beams of radiation to precisely target the tumour in high doses. You usually need 5 sessions given over 10 days. This is planned during your first appointment. You will meet with a radiation oncologist and lie on an examination table for a CT scan (in the same position as during treatment). A mesh mask keeps your head still, but can make some people feel anxious. The specialist will plan the treatment area, type of radiation and how to deliver the right dose.

Radiation therapists then deliver the treatment sessions over a number of days. A treatment session doesn’t take very long and you can usually go home after each one.

Proton beam radiation therapy

This uses proton beams rather than x-ray beams. Protons release most of their radiation within the cancer, protecting nearby tissue. Treatment is given in high doses over several days. Proton therapy is most useful near very sensitive areas. It’s not currently operating in Australia but may be available in the future. Talk to your radiation oncologist about your options.

Laser therapy or photodynamic therapy

Laser treatment uses an infrared laser to heat and destroy cancer cells. Laser treatment is sometimes combined with photodynamic therapy, which uses a laser combined with a light-sensitive drug to destroy cancer cells. The drug is injected into your vein and makes the cells in your body more sensitive to light. The treatment is painless, but you will be sensitive to light for several days after treatment.

Immunotherapy

Immunotherapy is a drug treatment that uses your body’s immune system to fight cancer. Immunotherapy for uveal melanoma that has spread is available for eligible patients (visit eviQ for more information). Other immunotherapy drugs may become available, and some are being investigated in clinical trials. Ask your doctor if these treatments are suitable for you.

Targeted therapy

Targeted therapy is a drug treatment that targets specific features of cancer cells to stop the cancer growing and spreading. Drugs are given as tablets or through a drip into a vein. They travel through the body like chemotherapy, but they work in a more focused way. A clinical trial is testing targeted therapy for eye melanoma. Your doctors may test the cancer cells (from a biopsy) to see if this treatment is likely to work for you.
