[Interleukin-6 in patients with uveal melanoma].

Studies of the blood serum and tears of patients with uveal melanoma revealed local (14.3%) and total-systems (11.1%) production of interleukin-6 (IL-6). Surgery stimulates IL-6 production in the serum (22.2%) and more so in tears (57.1%). The rate of IL-6 detection in the serum and the iridociliary localization of the tumor correlated with tumor development from stage T3 to stage T4. However, we failed to find out precisely the role of this cytokine.
