Prognostic impact of platelet/lymphocyte and neutrophil/lymphocyte ratios in patients with gastric cancer: a multicenter study.

Background: Increasing amounts of evidence suggest patient-related systemic inflammatory response (SIR) as a powerful prognostic factor in cancer and applicability of SIR as a prognostic factor has been investigated.

Aim: To evaluate the prognostic significance of SIR, which is among routinely analysed blood parameters in patients with all stages of gastric cancer (GC).

Methods: A total of 245 patients with gastric cancer who were followed up and treated in four clinics of medical oncology were included in the study.
