[Significant prognostic factors in stage IV gastric cancer]

The aim of this study was to evaluate clinicopathological variables, including the granulocyte-to-lymphocyte ratio(G/L ratio), as prognostic factors for Stage IV gastric cancer patients. A total of 70 patients treated for Stage IV gastric cancer were enrolled in this study. Univariate analysis indicated that age ≥70 years, performance status >2, resection not being performed, chemotherapy not being administered, high C-reactive protein(CRP)levels, and carbohydrate antigen 19-9 levels were significantly associated with poor survival. Multivariate analysis of these factors identified resection not being performed, chemotherapy not being administered, and high CRP levels as independent unfavorable factors of survival. Although the G/L ratio was not a prognostic factor for Stage IV gastric cancer patients in this study, further studies with greater number of patients are required to determine whether the G/L ratio is a significant biomarker associated with survival.
