Objectives: Increasing evidence has demonstrated that upregulation of
programmed death cell ligand-1 (PD-L1) and FOXP3-positive regulatory T cells in
different malignancies plays a critical role in tumor progression. In the present
study, the evaluation of PD-L1 and FOXP3 tissue expressions in a spectrum of
cervical neoplasms were performed. Material and method:
Immunohistochemical PD-L1 and FOXP3 expressions were evaluated in a total of 107
formalin-fixed, paraffin-embedded uterine cervical neoplasm specimens, and their
association with some pathological parameters was tried to be elucidated.
Results: Cases with low or high squamous intraepithelial lesion (n =
59), squamous cell carcinoma (n = 27), adenosquamous carcinoma (n = 15) and
adenocarcinoma (n = 6) were included in this study. Tumoral PD-L1 was detected in
most squamous cell carcinomas while it was found in almost none of the
intraepithelial lesions (p
