          Abstract

          CD4(+) T cells play a central role in initiating and maintaining anticancer immune responses. However, regulatory CD4(+)CD25(+) T cells which express Foxp3 have also been shown to inhibit antitumor effector T cells. In view of these heterogeneous CD4(+) T-cell populations, this study was designed to determine the prognostic value of various tumor-infiltrating CD4(+) T-cell populations in head and neck squamous cell carcinoma. Eighty-four newly diagnosed untreated patients with histologically proven primary head and neck squamous cell carcinoma were included in this study. Double or triple immunofluorescence staining was done to assess and quantify the activated CD4(+)CD69(+) T cells, regulatory CD4(+)Foxp3(+) T cells, and mixed CD4(+)CD25(+) T cells comprising both activated and regulatory T cells. On univariate analysis, high levels of tumor-infiltrating CD4(+)CD69(+) T cells were correlated with both better locoregional control (P = 0.01) and longer survival (P = 0.01). Infiltration by regulatory Foxp3(+)CD4(+) T cells was positively associated with a better locoregional control of the tumor. Multivariate analysis showed that the only significant prognostic factors related to locoregional control were T stage (P = 0.02) and CD4(+)Foxp3(+) T-cell infiltration of the tumor (P = 0.02). In the Cox multivariate analysis, only two variables influenced overall survival probability: T stage (P = 0.036) and CD4(+)CD69(+) T-cell infiltration (P = 0.017). This study shows that tumor-infiltrating activated CD4(+)CD69(+) T cells are associated with a good prognosis in head and neck squamous cell carcinoma. In addition, regulatory Foxp3(+)CD4(+) T cells are positively correlated with locoregional control may be through down-regulation of harmful inflammatory reaction, which could favor tumor progression.
