Abstract

Background/aim

The role of tumour-infiltrating CD45Ro⁺ T-cells in oral squamous cell carcinoma (OSCC) is unclear. This study aimed to evaluate prognostic biomarkers for OSCC.

Patients

We determined the density of tumour-infiltrating CD45Ro⁺ T cells in the parenchyma and stroma at the tumour centre (TCe) and invasive front (IF) and examined the association between the density of these cells and histopathological status in 142 patients.

Results

Five-year overall survival (OS) and recurrence-free survival were favourable in patients with high CD45Ro⁺ T-cell density in the TCe stroma. OS was favourable in patients with high CD45Ro⁺ T-cell density in the IF stroma. Stepwise Cox regression model analysis indicated that CD45Ro⁺ T-cells in the stroma of the IF and TCe were an independent prognostic factor for OS.

Conclusion

CD45Ro⁺ T-cells in the stroma of the IF and TCe play a role in cancer immune surveillance and may be a useful prognostic factor.
