PURPOSE: The neutrophil-to-lymphocyte ratio is a simple biomarker that reflects the balance between the systemic inflammatory and immunity status. Here we investigate the prognostic role of pre-treatment neutrophil-to-lymphocyte ratio (NLR) in an Asian cohort of oropharyngeal squamous cell carcinoma (OPSCC) patients.
METHODS: A retrospective review of OPSCC patients from a tertiary institution was conducted. The NLR was calculated from the haematological specimen taken within a month before treatment. Survival rates were estimated via the Kaplan-Meier method, and Cox proportional hazards regression was performed for univariable and multivariable analyses. The NLR cutpoint was determined using maximally selected log-rank statistics.
RESULTS: In a cohort of 148 OPSCC patients, 43% were p16-positive and 44% were p16-negative, with a median follow-up of 24 months. The p16-positive patients were younger (median age 62 vs. 67 years) and exhibited a lower prevalence of heavy smoking (47% vs. 69%). The p16-negative cases frequently presented at an advanced disease stage (74% vs. 41%), with a history of previous radiotherapy (26% vs. 3%). The p16-negative patients displayed a higher median NLR (2.91 vs. 2.49). The 3-year disease-specific survival (DSS) in p16-positive was higher compared to p16-negative patients (89.9% vs. 41.6%). The optimal NLR cutpoint was determined as 3.56 and predicted for decreased DSS (hazard ratio [HR] 2.59, p = 0.004). Multivariable analysis revealed smoking, high NLR ≥ 3.56, and p16-negativity as independent variables associated with poorer DSS and overall survival (OS) across the cohort.
CONCLUSION: A high NLR is independently prognostic of poorer DSS in OPSCC, independent of p16 and smoking status. A NLR of more than 3.56 was highly prognostic for poorer survival and warrants further validation in larger cohorts of OPSCC.
