Prognostic value of NLR and PLR in oral squamous cell carcinoma patients: A cohort study from tertiary cancer center
Vandana Mohta, Renuka Badanale, Shilpa NellikkalABSTRACT
Introduction:
Oral cancer remains a major health burden in developing countries like India and across South-East Asia. There is a need for newer, cheaper, and reliable biomarkers to aid in early detection, prognosis, and personalized treatment strategies.
Methods:
A cohort study of 110 operated oral squamous cell carcinoma (OSCC) patients was conducted at a tertiary cancer center in India (January 2020–May 2021). Neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and clinicopathological features were analyzed using Statistical Package for the Social Sciences version 28.0. Associations with tumor characteristics were assessed via Mann–Whitney U and Chi-square tests. R curves and Youden’s index identified optimal NLR/PLR cutoffs. Overall survival (OS) and disease-free survival (DFS) were analyzed using Kaplan–Meier and compared with the log-rank test (
Results:
Among 110 patients (87 men, 23 women; age 22–72), buccal mucosa was the most common tumor site (42.7%), with most in stage IV. Mean follow-up was 15.5 months. NLR showed good prognostic value (AUC (area under the curve): 0.733; cutoff: 3.04), and PLR showed fair value (AUC: 0.640; cutoff: 131.28). Both were significantly higher in females (
Conclusion:
NLR and PLR are cost-effective, accessible prognostic biomarkers in OSCC and are significantly associated with recurrence, advanced disease, and survival outcomes.
