Taken together, these findings suggest that deregulation of Fas, overexpression of FasL, and the inverse correlation between FasL overexpression and the presence of CD45+ tumor-infiltrating lymphocytes in CC tissues as reported previously (20), could indicate that FasL induced apoptosis in local (cervical) lymphocytes to favor the immune evasion of tumor cells. This evidence concerns the gene PTPRC and neoplasm.
