ABSTRACT
We compared the sensitivity and specificity of S-100 and MIA in advanced melanoma, in 96 patients with no evidence of disease (NED) and 86 patients with metastatic melanoma. Abnormal S100 (>0.2 microg/l) and MIA (>14 ng/ml) results were found in 1.1% and 3.2% of NED patients and in 59.3% and 54.6% of the patients with active melanoma (p<0.001). Using both tumor markers simultaneously, the sensitivity increased up to 69.8% with the same specificity 96.8%. S100 serum levels were not related to growth patterns. By contrast, MIA levels seemed to be related to the growth pattern, with higher levels in nodular melanoma (60.6+/-87.1 ng/ml) compared with acral-lentigous melanoma (11.9+/-5.4 ng/ml) (p=0.02). Likewise, S100 was related to the metastases site with significantly higher sensitivity and mean concentrations in patients with brain metastases (p=0.01) with the lowest in those with lung MI. MIA was related to the same metastases locations but without statistical significance. In summary, both S100 and ML4 are useful markers related to prognostic factors, being more effective when used in combination.
