Systemic-inflammation-based score can predict prognosis in metastatic gastric cancer patients before first-line chemotherapy

Aim: Systemic inflammatory response affects survival of gastric cancer (GC) patients. This study was carried out to create a prognostic inflammatory-based score to predict survival in metastatic GC (mGC) before first-line chemotherapy. Materials & methods: We studied the prognostic value of neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio in 151patients with mGC at the diagnosis. Results: Median overall survival (OS) was significantly lower in patients with high NLR. Performance status 1-2according to the Eastern Cooperative Oncology Group scale and NLR were predictors of shorter OS at multivariate analysis. Based on these results, we defined a prognostic OS score, showing a better median OS in favorable risk group. Conclusion: Elevated pretreatment NLR and Eastern Cooperative Oncology Group are independent predictors of shorter OS in mGC patients before first-line chemotherapy.
