Overview
Common risk factors in the development of uveal melanoma are cutaneous and iris nevi, host pigmentation factors, and ultraviolet light exposure, caucasian race, and certain inherited skin disorders such as dysplastic nevus syndrome and ocular melanocytosis.
Risk Factors
Common risk factors in the development of uveal melanoma include:[1][2][3]
Cutaneous and iris nevi
- The risk of progression of iris nevi to melanoma at 5, 10, 15, and 20 years is 3, 4, 8, and 11 percent, respectively. Significant risks factors associated with an increased risk of transformation include younger age, inferior location, diffuse pigmentation, presence of blood in the lesion, ectropion, and a feathery margin.[4]
- Generally, choroidal melanoma arises in pigmented nevi. The risk of progression to melanoma at 5, 10, and 15 years is 9, 13, and 17 percent, respectively.[5]
- Significant risk factors associated with an increased risk of transformation of choroidal nevi to choroidal melanoma include the following:
- Thickness greater than 2 mm,
- Subretinal fluid accumulation
- Symptoms such as decreased vision and presence of flashes or floaters
- Presence of orange pigment
- Distance from the optic nerve less than 3 mm,
- Hollow rather than solid on ultrasound
- Absence of a halo.
Host pigmentation factors
- Light eye color
- Fair skin color
- Propensity to sunburn
Ultraviolet light exposure
Caucasian race
Inherited skin disorders
- Certain inherited skin disorders such as dysplastic nevus syndrome may increase the risk of developing melanoma on skin and in eye. Some people with ocular melanocytosis with abnormal skin pigmentation involving the eyelids and adjacent tissues and increased pigmentation on their uvea have an increased risk of developing eye melanoma.
- Approximately 0.6% uveal melanomas are considered to be familial. Uveal melanomas may occur as a part of familial syndromes such as xeroderma pigmentosa, Li-Fraumeni syndrome and familial breast and ovarian cancer. Approximately 0.0017% of the primary uveal melanoma patients were in the setting of familial atypical mole and melanoma syndrome (FAMM). Patients with this syndrome were relatively young with a mean age of 40 years. An association of neurofibromatosis type 1 and uveal melanoma has also been suggested as both are of neural crest origin. Oculodermal and ocular melanocytosis, dysplastic nevi and cutaneous melanoma are associated with an increased risk of uveal melanoma development. Ocular and oculodermal melanocytosis are approximately 35 to 70 times more common in uveal melanoma patients.[6]
