The analysis of literature revealed that men experience uveal melanoma (UM) more frequently and with worse prognosis. There are also descriptions of an aggressive course of UM in pregnant women. These facts prompted researchers to analyze the effect of sex hormones and pregnancy on the development and progression of UM. Many years of international experience have refuted the presence of a reliable difference between 5-year survival and 5-year survival without metastases between non-pregnant women with UM and pregnant women with UM. That data is regarded as level 3 evidence. The experts have concluded that UM is not a contraindication to current or future pregnancy, and exogenous hormones (oral contraceptives or hormone replacement therapy) do not affect the incidence and prognosis of UM. Publications provide evidence of expression of the receptors of certain sex hormones (ER, ERRα, LH and LHRH) in primary UM, as well as overexpression of the ESR1 and ESR2 genes in UM with poor predictive characteristics. Overall AR mRNA expression in UM was low, but it was higher in epithelial UMs. The fact of expression of estrogen receptors in UM gives grounds to experiment with them as a target for therapy.
