Medium and Large Choroidal Melanoma
Eye-sparing radiation therapy, either by plaque brachytherapy or external beam, is the preferred option for most patients with medium-sized choroidal melanoma. Enucleation remains the standard therapy for large, choroidal melanomas and melanomas that cause severe glaucoma or invade the optic nerve.
Standard treatment options:
Tumor growth pattern is a factor in the therapeutic decision. If there is a diffuse melanoma or if there is extraocular extension, enucleation should be considered, but radiation therapy can be employed for less extensive disease.
Medium-sized choroidal melanomas
- Plaque radiation therapy.[1-4]
- External-beam, charged-particle radiation therapy: This approach is offered at specialized referral centers. It requires careful patient cooperation, with voluntary fixation of gaze.[5-7]
- Local eye-wall resection.[8,9]
- Combined therapy, with ablative laser coagulation or transpupillary thermotherapy to supplement plaque treatment.[10,11]
- Enucleation. This approach is considered primarily for diffuse melanomas or for cases in which there is extraocular extension; radiation complications or tumor recurrence may sometimes make enucleation necessary.
Large choroidal melanomas
- Enucleation when the tumor is judged to be too large for eye-sparing approaches.
Check for U.S. clinical trials from NCI's list of cancer clinical trials that are now accepting patients with ciliary body and choroid melanoma, medium/large size. 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.References
