Abstract
BACKGROUND: Inflammatory response is known to play a vital role in carcinogenesis and cancer progression. The prognostic relevance of monocyte-to-lymphocyte ratio (MLR), as a biomarker of inflammatory response has been demonstrated in patients with hematologic cancers. OBJECTIVES: In this study, we assessed the prognostic relevance of MLR in patients with resectable lung carcinoma. METHODS: Clinical records of 705 lung cancer patients who underwent radical resection at our hospital between October 2006 and January 2011 were retrospectively reviewed. The optimal cutoff value of MLR as a prognostic indicator was determined on receiver operating characteristic curve analysis. RESULTS: On multivariate analysis using Cox proportional hazards regression model, MLR was an independent predictor of both overall survival (hazard ratio [HR] 1.494, 95% confidence interval [CI] 1.158-1.927, P = .002) and disease-free survival (HR 1.547, 95% CI 1.172-2.043, P = .002). CONCLUSIONS: Preoperative MLR may be a simple, reliable prognostic marker for risk stratification and be used to guide treatment decision-making in lung cancer patients.
