BACKGROUND: In cutaneous melanoma, the S-100-beta serum level is recognized as a marker of metastatic disease. OBJECTIVES: To determine whether S-100-beta is present in the serum of patients with uveal melanoma and to test whether the serum concentration of S-100-beta is related to known clinical and histopathological prognostic factors in these patients. METHODS: The S-100-beta concentration was measured in serum samples collected from 64 patients with uveal melanoma before enucleation and from 58 healthy control subjects. A 2-site immunoluminometric assay was used to quantify the S-100-beta concentration in serum. S-100-beta concentrations in the serum from patients were compared with clinicopathological tumor variables, sex, occurrence of metastasis, and survival. RESULTS: Thirty-seven (57.8%) of 64 patients with uveal melanoma showed detectable levels of serum S-100-beta. There was, however, no significant difference between serum levels of patients and control subjects (P =.71). Statistical analysis showed no significant correlation between S-100-beta concentration and any of the clinicopathological tumor variables, occurrence of metastases, or survival. Only sex was correlated with S-100-beta serum levels, which was not observed in the control group. CONCLUSIONS: In our study on patients with uveal melanoma, the S-100-beta serum concentration was not correlated with any investigated prognostic factor and was not of prognostic value itself. Female patients appeared to have higher S-100-beta concentrations than male patients.
