OBJECTIVES/HYPOTHESIS: Elevated inflammatory biomarkers such as C-reactive protein (CRP) and the recently identified neutrophil/lymphocyte ratio (NLR) were demonstrated to be associated with prognosis in human cancers. The aim of our present study is to analyze the relationship of preoperative levels of CRP and NLR with clinicopathological factors and prognosis in oral squamous cell carcinoma (OSCC) patients. STUDY DESIGN: Retrospective study. METHODS: This study was performed on 226 OSCC patients between July 2007 and April 2012. Their serum CRP levels and NLR were measured preoperatively. RESULTS: CRP level ≥ 5.0 mg/L was significantly associated with NLR ≥ 2.44 (linear regression, P < .001). Elevated CRP and NLR were significantly associated with pathological tumor status (P < .001), pathologic nodal metastasis (P < .001), tumor depth (≥10 mm vs. <10 mm, P < .001), disease-free survival (P < .001), and overall survival (P = .001). The influence of CRP level and NLR on disease-free survival (hazard ratio [HR] = 2.259, 95% confidence interval [CI] = 1.170-4.361) and overall survival (HR = 2.176, 95% CI = 1.116-4.245]) still existed after adjusting for tumor status, lymph node metastasis, and tumor cell differentiation. CONCLUSIONS: The present study demonstrates that elevated CRP is an independent prognostic factor in OSCC. Elevated NLR in the high CRP group identifies patients at high risks of recurrence and shorter survival. Incorporating NLR into CRP level therefore has significant potential as a biomarker for risk stratification in OSCC.
