Abstract: PURPOSE: To investigate the value of derived neutrophils to lymphocyte ratio (dNLR) in predicting the survival and prognosis of patients with locally advanced oral squamous cell carcinoma(LAOSCC). METHODS: Patients of stage Ⅲ/ⅣA LAOSCC disease who accepted radical surgery and postoperative radiotherapy from a phase Ⅲ trial (NCT01542931) were enrolled. Based on their baseline clinical data and ten-year-follow-up visiting data, receiver operating characteristic curves (ROC) were built and area under the curve (AUC) was computed to determine dNLR cutoff points, according to Youden's index. The patients were then grouped into low dNLR group and high dNLR group. Kaplan-Meier estimates of survival and Cox proportional hazards models were used for longitudinal analysis. The primary outcome was overall survival (OS). The second outcome was disease-free survival(DFS), local recurrence-free survival(LRFS) and distant metastasis-free survival(DMFS). SPSS 25.0 software package was used for data analysis. RESULTS: A total of 115 patients with LAOSCC were enrolled in this study, with an average age of (54.5±10.7) years and an average follow-up time of (80.3±55.5) months. dNLR cutoff point was 1.555. Multivariate analysis showed dNLR was an independent negative predictive factor for survival (OS: HR=1.172, 95%CI: 1.028-1.337, P=0.018; DFS: HR=1.123, 95%CI: 1.001-1.282, P=0.050; LRFS: HR=1.137, 95%CI: 1.002-1.291, P=0.047; DMFS: HR=1.162, 95%CI: 1.020-1.324, P=0.024). CONCLUSIONS: dNLR is an independent negative predictive factor in patients with LAOSCC. Patients of lower baseline dNLR achieve better long-term prognosis.
