Abstract: | Objective: The purpose of this study was to evaluate the predictive power of the platelet to albumin ratio (PAR) on survival outcomes of patients with non-small-cell lung cancer (NSCLC).Patients and Methods: In all, 198 patients with NSCLC were recruited. The X-tile software was performed to identify the optimal cutoff values for PAR, platelet to lymphocyte ratio (PLR), and neutrophil to lymphocyte ratio (NLR). The Kaplan–Meier method, univariate and multivariate analyses Cox regression were used to analyze the prognostic factors for overall survival (OS).Results: In all, 198 patients were enrolled, containing 146 (73.7%) men and 52 (26.3%) women. The optimal cutoff values for PAR, PLR, and NLR were 8.8×109, 147.7, and 3.9, respectively. Patients with PAR > 8.8 × 109 (P <0.001), PLR > 147.7 (P <0.001), and NLR >3.9 (P = 0.007) were associated with poor OS. Multivariate analyses found that PAR was an independent predictor in NSCLC patients (hazard ratio HR]: 4.604, 95% confidence interval CI]: 2.557–8.290, P <0.001).Conclusion: Preoperative PAR is a useful and potential prognostic biomarker in NSCLC patients who have received primary resection. |
