The sensitivity and specificity of serum sCD163 in cutaneous melanoma were 84.6 and 87.0%, respectively (p = 0.0030; Figure 1B), whereas the sensitivity and specificity of serum sCD163 in non-cutaneous melanoma were 100 and 66.7%, respectively (p = 0.3154; Figure 2B). This evidence concerns the gene CD163 and cutaneous melanoma.
