During metastasis, they are thought to play a role in determining cancer cell distribution and target organs. The aim of this study was to examine the expression of the chemokine receptors CXCR4, CCR7 and CCR10 as well as their respective chemokine ligands (CXCL12, CCL19, CCL27) in human uveal melanomas.<\/jats:p><jats:p><jats:bold>Methods:\u2002<\/jats:bold> Seventy formalin\u2010fixed paraffin\u2010embedded uveal melanoma specimens from patients treated in 1996\u20131997 were examined using immunohistochemistry and evaluated using an immune reactive score (IRS).<\/jats:p><jats:p><jats:bold>Results:\u2002<\/jats:bold> The chemokine receptors CXCR4, CCR7 and CCR10 were primarily expressed in the cytoplasm of uveal melanoma cells, with CXCR4 (average IRS 8.2) and CCR7 (average IRS 5.7) showing the strongest expression, respectively. The chemokine ligand CCL19 demonstrated a moderate expression (average IRS 5.3), whereas the expression of receptor CCR10 (average IRS of 3.4), ligand CCL27 (average IRS 2.5) and ligand CXCL12 (average IRS 0.6) by uveal melanoma cells was low. A significant association between liver metastases and chemokine expression was found for CCR7 expression (p\u2003=\u20030.037) only. Comparison of liver metastasis and choroid uveal melanoma (35.3%, <jats:italic>n<\/jats:italic>\u2003=\u200312 of 34) versus ciliary body involvement (72.7%, <jats:italic>n<\/jats:italic>\u2003=\u20038 of 11) was significant (p\u2003=\u20030.030).<\/jats:p><jats:p><jats:bold>Conclusion:\u2002<\/jats:bold> Chemokine receptors are more strongly expressed on uveal melanoma cells than their ligands.
