Localized plaque radiation therapy is a type of internal radiation therapy that may be used for tumors of the eye. Radioactive seeds are attached to a disk, called a plaque. The plaque is placed directly on the wall of the eye where the tumor is located. The side with the seeds faces the eyeball and delivers radiation to the eye. The plaque, which is often made of gold, helps protect nearby tissues from radiation damage.
Plaque radiotherapy of the eye. A type of radiation therapy used to treat eye tumors. Radioactive seeds are placed on one side of a thin piece of metal (usually gold) called a plaque. The plaque is sewn onto the outside wall of the eye. The seeds give off radiation which kills the cancer. The plaque is removed at the end of treatment, which usually lasts for several days.
Charged-particle external beam radiation therapy is a type of external-beam radiation therapy. A special radiation therapy machine aims tiny, invisible particles, called protons or helium ions, at the cancer cells to kill them with little damage to nearby normal tissues. Charged-particle radiation therapy uses a different type of radiation than the x-ray type of radiation therapy.
Gamma Knife therapy is a type of stereotactic radiosurgery used for some melanomas. This treatment can be given in one treatment. It aims tightly focused gamma rays directly at the tumor so there is little damage to healthy tissue. Gamma Knife therapy does not use a knife to remove the tumor and is not an operation.
Photocoagulation is a procedure that uses laser light to destroy blood vessels that bring nutrients to the tumor, causing the tumor cells to die. Photocoagulation may be used to treat small tumors. This is also called light coagulation.
Thermotherapy is the use of heat from a laser to destroy cancer cells and shrink the tumor.
New types of treatment are being tested in clinical trials.
Information about clinical trials is available from the NCI Web site.
Patients may want to think about taking part in a clinical trial.
