T regulatory cell markers in oral squamous cell carcinoma: Relationship with survival and tumor aggressiveness.

Tumor-infiltrating lymphocytes (TILs) are a heterogeneous cell family which plays an important role in tumor-associated immune response. Of these, T regulatory (Treg) cells have also been shown to inhibit anti-tumor response. We aimed to evaluate the expression of T regulatory cell markers (CD4, CD25, CTLA-4 and FoxP3) in samples of oral cavity squamous cell carcinoma (OCSCC) and lip SCC (LSCC) by immunohistochemistry.
