Sarcopenia with modified Glasgow prognostic score as a predictor of long-term survival in patients with gastric cancer.

Abstract

27 Background: Recent reports suggested that the Glasgow prognostic score (GPS), which is a preoperatively determined inflammation-based score, correlated with long -term survival in several types of cancers. The aim of this study is to create new prognostic index which is superior to modified GPS (mGPS) in gastric cancer. Methods: Seventy five patients with gastric cancer who underwent gastrectomy were enrolled in this study. Prognostic factors were searched for among clinocopathological factors and nutritional- or immune- parameters, including mGPS (J Gastoenterol 2011), neutrophil lymphocyte ratio (NLR), prognostic nutritional index (PNI), or sarcopenia. Cut of value were 3.0: NLR, 40: PNI, respectively. Sarcopenia was assessed by the following CT-based methods (Lancet 2011). Sarcopenia with mGPS (SarcoGPS) were defined as CRP was changed to sarcopenia. Results: The overall survival (OS) rate was significantly lower in mGPS:0 group than in mGPS:1,2 group (p < 0.05). The disease-free survival (DFS) rate didn’t differ in mGPS (N.S). The OS and DFS rate of high NLR group or sarcopenia group were significantly lower than those of low NLR group or non- sarcopenia group (p < 0.05). PNI did not differ significantly both in OS and DFS. SarcoGPS was the poor prognostic factor both in OS and DFS (p < 0.01) Conclusions: SarcoGPS is the new prognostic index, which is superior to mGPS, in gastric cancer.
