The value of pretreatment glucose-to-lymphocyte ratio for predicting survival of metastatic gastric cancer.

To demonstrate the prognostic importance of glucose-to-lymphocyte ratio (GLR) in metastatic gastric cancer (mGC). Retrospectively, 159 mGC patients were enrolled. Kaplan-Meier curve and Cox regression analysis were used to determine the prognostic value of the systemic immune inflammation index (SII), neutrophil-to-lymphocyte ratio (NLR), prognostic nutritional index (PNI) and GLR. Progression-free survival (PFS) and overall survival (OS) were associated with NLR, PNI, SII and GLR by univariate analysis. Moreover, OS was associated with Eastern Cooperative Oncology Group performance status and the chemotherapy regimen. In multivariate analysis, only GLR was found to be independently prognostic for both PFS and OS. In mGC, GLR may be a new prognostic marker for both OS and PFS.
