Two major and two minor tumor expression patterns of EpEX, Sox2 and vimentin were observed in the LMU cohort: High expression of EpCAM and Sox2, but lack of vimentin expression (EpEX/Sox2+/vimentin− 43.01%), high expression of all three antigens (EpEX/Sox2/vimentin+ 35.48%), high expression of EpCAM and vimentin, but lack of Sox2 expression (EpEX/vimentin+/Sox2− 7.53%) and high expression of EpCAM, but lack of Sox2 and vimentin expression (EpEX+/Sox2/vimentin− 3.23%). This evidence concerns the gene SOX2 and neoplasm.
