Pearson’s correlation analysis underscored the direct association of CD1c, CD2, CD3, CD4, CD11c, CD14, CD20, CD44, CD56, CD63, CD69, CD86, CD105 and CD146 levels to the presence of the tumor, while CD24, CD31, and CD40 epitopes showed a significant positive correlation with nodal involvement (p < 0.01), despite not being overexpressed specifically in tumor samples compared to healthy ones. This evidence concerns the gene PECAM1 and neoplasm.
