Extraocular Extension and Metastatic Intraocular Melanoma
Extrascleral extension usually confers a poor prognosis. For patients with gross tumor involvement of the orbit, treatment requires orbital exenteration often combined with preoperative or postoperative radiation therapy; however, there is no evidence that this radical surgery will prolong life. Most patients with localized or encapsulated extraocular extension are not exenterated. This subject is controversial.[1,2,3,4,5]
No effective method of systemic treatment has been identified for patients with metastatic ocular melanoma.
Skin cancers involve abnormal cell changes in the outer layer of skin.
It is by far the most common cancer in the world, accounting for 75% of all cancer diagnoses. Most cases are cured, but the disease is a major health concern because it affects so many people. The incidence of skin cancer is rising, even though most cases could be prevented by limiting the skin's exposure to ultraviolet radiation.
Skin cancer is about three times more common in men than in women, and the risk...
Check for U.S. clinical trials from NCI's list of cancer clinical trials that are now accepting patients with extraocular extension melanoma and metastatic intraocular melanoma. The list of clinical trials can be further narrowed by location, drug, intervention, and other criteria.
General information about clinical trials is also available from the NCI Web site.
