| Descripción: | Introduction High values of neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) are related with poor prognosis in patients with gastric cancer. However, this association has been rarely assessed in Hispanic populations that show important clinicopathological differences to Asian and Caucasian patients. In this study, we determined the prognostic value of these biomarkers in Hispanic patients from Costa Rica. Materials and Methods We retrieved data regarding pre-treatment NLR and PLR, as well as clinical variables from medical records of 381 consecutive gastric cancer patients treated in four major hospitals in Costa Rica between 2009 and 2012. Univariate and multiple Cox regression analyses were performed to assess the value of NLR and PLR as predictors of overall survival (OS) and disease-free survival (DFS). The best cutoff point was based on the maximization of the Log-rank test. Results Median follow-up was 13.21 months. In univariate analysis, a NLR ≥ 5 was associated with reduced DFS (hazard ratio (HR) 2.31; 95% confidence interval (CI) 1.78–3.00; p < 0.001) and poor OS (HR 2.24; 95% CI 1.72–2.92; p < 0.001). Similarly, a PLR ≥ 350 was associated with worse DFS (HR 2.28; 95% CI 1.70–3.06; p < 0.001) and poor OS (HR 2.33; 95% CI 1.73–3.13; p < 0.001). After adjustment for potential confounders, multivariate analysis revealed that only the NLR ≥ 5 was independently associated with worse DFS (HR 1.97; 95% CI 1.44–2.47) and OS (HR 1.59; 95%CI 1.15–2.28). Conclusions NLR ≥ 5 was independently associated with worse OS and DFS in Hispanic patients with gastric cancer. |
