Objectives: The role of the immune system in head and neck squamous cell carcinoma is controversial. The aim of our study was to analyze full blood counts and distribution of T cell subsets in patients affected by laryngeal squamous cell cancer (LSCC) and their association with clinical variables and survival. Study design: Retrospective study. Methods: We analyzed the levels of platelets, lymphocytes, and neutrophils, as well as the CD4+, CD8+, and CD3+ T-cell subpopulations by cytofluorometry in LSCC patients. A cohort of healthy patients was used as control group. The disease-specific survival (DSS) was considered as survival outcome. Results: Sixty-five LSCC patients and 48 controls were enrolled. In LSCC patients, neutrophils were higher than in the healthy group (P < .0001). The neutrophil-to-lymphocyte ratio (NLR) and the platelet-to-lymphocyte ratio (PLR) were both higher in LSCC patients (P < .0001). In patients treated for recurrent disease, the CD8+/CD3+ ratio was increased (P = .02), while the CD4+/CD8+ (P = .03) and CD4+/CD3+ (P = .04) ratios were lower. In patients with lymph node metastases, leukocytes (P = .03), CD3+ (P = .04), and CD4+ (P = .0098) were all higher. Among Stages III-IV patients, low lymphocyte and low leukocyte count were associated with worse DSS. Conclusion: Our data demonstrate that NLR and PLR are significantly increased in LSCC. Lower CD4+/CD8+ and CD3+/CD8+ ratios are related to recurrent disease and a higher level of CD3+ and CD4+ is associated with nodal metastasis.

Abstract

The aim of our study was to analyze full blood counts and distribution of T cell subsets in patients affected by laryngeal squamous cell cancer (LSCC) and their association with clinical variables and survival. Study design: Retrospective study. Methods: We analyzed the levels of platelets, lymphocytes, and neutrophils, as well as the CD4+, CD8+, and CD3+ T-cell subpopulations by cytofluorometry in LSCC patients. A cohort of healthy patients was used as control group. The disease-specific survival (DSS) was considered as survival outcome. Results: Sixty-five LSCC patients and 48 controls were enrolled. In LSCC patients, neutrophils were higher than in the healthy group (P < .0001). The neutrophil-to-lymphocyte ratio (NLR) and the platelet-to-lymphocyte ratio (PLR) were both higher in LSCC patients (P < .0001). In patients treated for recurrent disease, the CD8+/CD3+ ratio was increased (P = .02), while the CD4+/CD8+ (P = .03) and CD4+/CD3+ (P = .04) ratios were lower.
