Overview
If left untreated, 50% of patients with uveal melanoma may progress to develop metastasis. Common complications of uveal melanoma include glaucoma, vision loss, and metastasis. Prognosis is generally good for patients with iris melanoma, and the 10 year-survival for iris melanoma is approximately 95 percent and for ciliochoroidal tumors is 77 percent respectively.[1]
Natural History
The clinical course is unpredictable and metastatic disease can develop very late after a long disease-free interval. Uveal melanoma metastasizes haematogenously, predominantly to the liver.[2] Less than 4% of patients with uveal melanoma have detectable metastatic disease, at the time of diagnosis. However in further course about half of patients will develop metastases. When metastatic disease appears it unavoidably leads to death because of lack of effective systemic treatment.[1]
Complications
Complications of eye melanoma includes the following:[3]
- Eye melanomas that are large often cause vision loss in the affected eye and may cause complications, such as retinal detachment, that also cause vision loss. If small eye melanomas occur in critical parts of the eye they may cause some vision loss. There may be difficulty seeing in the center of the vision or on the side. Advanced eye melanomas can cause complete vision loss.
- Anterior chamber hemorrhage
- Corneal decompensation wth edema and band keratopathy
- Metastasis
Eye melanoma can spread outside of the eye and to distant areas of the body, including the liver, lungs and bones.
Complications of therapy of uveal melanoma
- Complications of radiotherapy include the following:
- Radiation retinopathy
- Radiation maculopathy
- Radiation opticopathy
- Maculopathy
- Cataract
- Neovascular glaucoma
- Vitreous haemorrhage
- Retinal detachment and dryness
- Radiation retinopathy, opticopathy and neovascular glaucoma are responsible for the majority of secondary visual loss and secondary enucleations after therapy.
Prognosis
Poor prognostic factors for systemic disease include the follwing:
- The mortality rate for small (< 2 - 3 mm apical height), medium (3 - 8 mm apical height) and large (> 8 mm apical height) melanoma is 16%, 32% and 53% in 5 years, respectively.[10]
- Choroidal nevi are considered benign if there diameter and thickness are approximately ≤5 mm and ≤ 1 mm respectively. The mortality risk from such a lesion is essentially zero.[11]
- Ciliary body involvement[12]
- Presence of orange pigment overlying the tumor[5]
- Extrascleral extension[13][14][15][16]
- Histological and cytological factors associated with higher risk of metastasis includes the following:
- Presence and extent of cells with epitheliod morphology
- Presence of looping extracellular matrix patterns
- Increased infiltration of immune cells[17]
- Staining with several immunohistochemical markers[18]
- Cell type
- Cell type is the most commonly used predictor of outcome following enucleation, with spindle-A cell melanomas carrying the best prognosis and epithelioid cell melanomas carrying the least favorable prognosis. Nevertheless, most tumors have an admixture of cell types, and there is no clear consensus regarding the proportion of epithelioid cells that constitutes designation of a tumor as mixed or epithelioid.
- Several additional microscopic features can affect the prognosis of intraocular melanoma, including:[19]
- Mitotic activity.
- Lymphocytic infiltration.
- Fibrovascular loops
- Extraocular extension, recurrence, and metastasis are associated with an extremely poor prognosis, and long-term survival cannot be expected. Systemic metastases may be wide spread, with the liver > lung > bone > kidney > brain being a common sites for tumor deposits.
- Uveal melanoma disseminates hematogenously, with a high propensity for liver, which is the most common (93%) site of metastasizing, followed by lung (24%) and bones (16%). It can also metastasize in brain and skin, or any other site in the body. The majority of patients with metastatic disease have metastases in multiple sites of body. Patients without liver metastases or with liver being not the first site of metastases have better prognosis.
- Patients with iris melanoma have better prognosis. In patients with iris melanoma at 5 and 10 years of follow up metastases were found in 4.1%, and 6.9%, respectively, compared to 15% and 25%, respectively, for choroidal melanomas. Ciliary body melanoma carries worse prognosis with metastases found at 5 and 10 years follow up in 19% and 33%, respectively.
- Uveal melanoma does not spread to regional lymph nodes, due to lack of lymphatic drainage in uvea except in rare cases of direct invasion of conjunctiva and then through conjunctival lymphatics to regional lymph nodes. Five-year survival rates for uveal melanoma ranges from 69% to 81.6% and ten-year survival rates from 57% to 62%. After detection of metastases 80% of patients die within 1 year, and 92% within 2 year. Long term survivals are rare in patients with uveal melanoma, and mean survival is only few months.[1]
- The 5-year mortality rate associated with metastasis from ciliary body or choroidal melanoma is approximately 30%, compared with a rate of 2% to 3% for iris melanomas.
- Overall survival depends on tumour size, extraocular spread, and metastases. Even small (<10 mm diameter, <3 mm thickness) tumors still carry a 10-15% 5-year mortality.
- The 10 year-survival for iris melanoma is approximately 95 percent and for ciliochoroidal tumors is 77 percent respectively.
- The most important genetic alteration associated with poor prognosis in uveal melanoma is inactivation of BAP1, which most often occurs through mutation of one allele and subsequent loss of an entire copy of chromosome 3 (monosomy 3 ) to unmask the mutant copy.[20] Because of this function in inactivation of BAP1, monosomy 3 correlates strongly with metastatic spread.[21]
- Where BAP1 mutation status is not available, gains on chromosomes 6 and 8 can be used to refine the predictive value of the monosomy 3 screen, with gain of 6p indicating a better prognosis and gain of 8q indicating a worse prognosis in disomy 3 tumors.[22]
- In rare instances, monosomy 3 tumors may duplicate the BAP1-mutant copy of the chromosome to return to a disomic state referred to as isodisomy. Thus, isodisomy 3 is prognostically equivalent to monosomy 3, and both can be detected by tests for chromosome 3 loss of heterozygosity.[23]
- Monosomy 3, along with other chromosomal gains, losses, amplifications, and LOH, can be detected in fresh or paraffin embedded samples by virtual karyotyping.
- The most accurate prognostic factor is molecular classification by gene expression profiling of uveal melanomas. This analysis has been used to identify two subclasses of uveal melanomas:[24] [25]
- Class 1 tumors that have a very low risk of metastasis.
- Class 2 tumors that have a very high risk of metastasis.
- Gene expression profiling outperforms all of the above-mentioned factors at predicting metastatic spread of the primary tumor, including monosomy 3.[26][27][28]
- The tumor node metastasis (TNM) staging system of the American Joint Committee on Cancer takes into account the key factors involved which are known to be of prognostic significance.[29][7]
- The prognosis is usually poor when local control is not achieved with the initial treatment.[30] [31]
- Detection of circulating tumor cells at the time of diagnosis is an independent risk factor for relapse and shortened survival in patients at high-risk based upon clinical parameters.[32][33]
- The prognosis for any patient with recurring or relapsing disease is poor, regardless of cell type or stage.
