Clinical inflammatory biomarkers associated with the tumor stage of gastric cancer: retrospective analysis of a Hospital in Peru during the years 2018–2020

Introduction: Gastric cancer is a disease with a high rate of morbidity and mortality in the world. Objective: To determine which clinical inflammatory biomarkers are associated with the tumor stage of gastric cancer of the oncology service of the Hospital María Auxiliadora in Lima, Peru, during the years 2018-2020. Method: ology: Observational, analytical, cross-sectional and retrospective study. There was a sample of 110 patients. The PR values ​​were obtained from the absolute frequencies of the variables: serum albumin, Platelet-Lymphocyte Ratio (PLR) and Neutrophil-Lymphocyte Ratio (NLR). Results: : The average age was 63,727±13.85. 55.45% were female. The most frequent histopathological type was intestinal adenocarcinoma with 62.73%. In the bivariate analysis, an association was found between INL (PR:6.88 CI95% 2.36-20 p<0.001), IPL (PR:2.55 CI95% 1.68-3.86 p<0.001) and serum albumin (PR:3.16 CI95% 1.91-5.24 p<0.001) in the advanced clinical stage. The multivariate analysis found a relationship between INL and clinical stage (PR:4.11 CI95% 1.25-13.49 p=0.020) Conclusion: INL is an independent predictive factor in relation to the clinical stage of gastric cancer in this study.
