Abstract

BACKGROUND/AIMS
Markers of inflammation have been associated with outcomes in various cancers. The purpose of this study was to evaluate whether systemic inf lammatory markers and their f luctuations can predict survival and chemotherapy response in patients with metastatic gastric cancer (mGC).
METHODS
We retrospectively reviewed the records of 502 patients who received first-line palliative chemotherapy for mGC between 2007 and 2013. The neutrophil-to-lymphocyte ratio (NLR) and modified Glasgow prognostic score (mGPS) were assessed before and after chemotherapy to evaluate their association with survival. The NLR values were categorized into two groups based on a cut-off value of 3; mGPS values were classified as high versus low.
RESULTS
High prechemotherapy NLR was significantly associated with poor overall survival on univariate analysis (p = 0.002). On multivariate analysis, high prechemotherapy NLR (hazard ratio, 1.43; p < 0.001) was an independent prognostic factor for poor overall survival. However, the prechemotherapy mGPS was not significantly associated with survival. Continuously high NLR or a shift to high NLR postchemotherapy was associated with poor chemotherapy response as well as survival, while NLR reduction was associated with a good response (linear by linear association, p < 0.001) and a favorable prognosis.
CONCLUSIONS
Prechemotherapy NLR can be used as a prognostic factor in mGC, while the postchemotherapy NLR value may predict the chemotherapeutic response and prognosis. In contrast, mGPS has limited prognostic utility in mGC.
