To investigate the status of insulin resistance, metabolic syndrome, dyslipidemia, and serum adiponectin levels in patients with uveal melanoma and choroidal nevus were investigated. Our study included 86 patients with uveal melanoma, 38 patients with choroidal nevus, and 86 controls. Uveal melanomas were classified as small, medium, and large on the basis of Collaborative Ocular Melanoma Study (COMS) criteria. Patients with uveal melanoma had significantly higher homeostatic model assessment scores compared with patients with choroidal nevus (P < 0.001). Patients with uveal melanoma and choroidal nevus had significantly lower levels of serum adiponectin compared with controls (P < 0.001). Patients with uveal melanoma who developed systemic metastases had significantly lower levels of serum adiponectin levels compared with patients with nonmetastases during follow-up (P=0.018). When the largest tumors (COMS III) were compared, ciliary body melanomas were associated with significantly lower levels of serum adiponectin than choroidal melanomas. In patients who were treated with enucleation, epitheloid predominant and mixed cell-type tumors were associated with lower levels of serum adiponectin compared with tumors with spindle cell type, but this did not reach statistical significance. By providing an antiapoptotic and proangiogenic environment, low serum adiponectin levels and insulin resistance may play a role in promoting the growth of uveal melanocytic tumors and may contribute toward a more aggressive clinical course, adversely affecting the prognosis.
