Abstract
Background
The purpose of this multicenter study was to retrospectively investigate the prognostic significance of the tumor microenvironment, in relation to survival in a large cohort of patients with laryngeal squamous cell carcinoma (LSCC), using the method proposed by the International TILs Working Group in breast cancer.
Methods
All consecutive patients with biopsy-proven LSCC who underwent total laryngectomy (TL) between January 2014 and January 2023 were retrospectively included in the study. A retrospective review of medical records including surgical, pathological and follow-up reports was performed. The density of TILs was determined according to the recommendations of the International TILs Working Group.
Results
The study group included 186 patients with LSCC. High TILs were statistically correlated with reduced size and extension of primary tumor (pT stage) with a statistically significant value (S: p = 0.01; P: p = 0.0003) and without needs of salvage therapy (S: p = 0.03; P: p = 0.004). Low TILs were indicative of worse prognosis.
Conclusions
Our study confirmed the protective value of TILs and the prognostic role of the tumor microenvironment in LSCC; furthermore, our results showed that the score proposed by the International TILs Working Group for breast cancer can be applied to LSCC.
