Tumor Microenvironment and Immune Response in Lip Cancer

ABSTRACT:

Simple Summary

The presence of tumor-infiltrating lymphocytes (TILs) in the tumor milieu has been linked to better patient prognosis and response to chemo-radiotherapy in head and neck carcinoma, among other malignancies. We studied 60 cases of squamous cell carcinoma of the lip to assess the presence of TILs and their subpopulations and tertiary lymphoid structures (TLSs) in the invading front and inner stroma of the tumor. Thereafter, we investigated the impact of histopathological parameters and prevailing conditions of the tumor microenvironment (TME) in TIL and TLS density. Lip SCCs appeared as more immunogenic compared to other HNCs. Poor lymphocytic infiltration was related to larger tumors, higher invasive ability, dense presence of activated stroma fibroblasts and express
