Summary

Evaluation of the prognostic potential of tumor-infiltrating lymphocytes and PD-L1 expression in non-metastatic squamous cell carcinoma of the head and neck

Detailed description

The role of the immune system in the process of tumor growth and progression in head and neck (HaN) cancer has become of increasing importance. In the last years, the concept of tumor immune microenvironment (TIME) with the presence of tumor cells (TC) and infiltrating immune cells (IC) has been intensively studied. The results of available clinical studies suggest a positive impact of tumor-infiltrating lymphocytes (TILs) on the prognosis of HNSCC patients and their overall (OS) and cancer specific survivals. Beside TILs, an integral component of TIME is the immunosuppressive activity represented by inhibitory signalling molecules expressed on tumor cells (TCs) and immune cells (ICs). One of these molecules is programmed death-ligand 1 (PD-L1), which inhibits the cytotoxic immune response mediated by T-lymphocytes. The aim of this observational cohort study is to assess the prognostic potential of novel immune biomarkers in patients with HNSCC tumors stage I-IVb treated with radical radiotherapy and radiochemotherapy. Specifically, the association between high and low TILs infiltration and OS and cancer specific survival parameters will be investigated. As well as the association between high and low PD-L1 expression and OS and cancer specific survival parameters will be investigated. This is a non-interventional study conducted in one institution - Department of oncology, University hospital Ostrava. The tumor immunoprofile defined by the presence of immune biomarkers (TIL, PD-L1) will be evaluated in each patient from biopsy specimens in representative hematoxylin and eosin stained sections by immuno-histochemistry. The Cox proportional risk model will be used to estimate the prognostic potential of each of the biomarker.
