Extraocular Extension and Metastatic Intraocular Melanoma
Extrascleral extension confers a poor prognosis. For patients with gross tumor involvement of the orbit, treatment requires orbital exenteration. However, there is no evidence that such 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. Available clinical trials should be considered as an option for these patients.
Note: Separate PDQ summaries on Skin Cancer Prevention, Skin Cancer Treatment, and Levels of Evidence for Cancer Screening and Prevention Studies are also available.
The only widely proposed screening procedure for skin cancer is visual examination of the skin, including both self-examination and clinical examination.
In asymptomatic populations, the effect of visual skin examination on mortality from nonmelanomatous skin cancers is unknown. Further, the evidence...
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.
