Abstract:
OBJECTIVETo explore whether neutrophil-lymphocyte ratio (NLR) is an effective prognostic marker in gastric cancer.
METHODSClinical data of 775 patients with gastric cancer in the First Affiliated Hospital of Sun Yat-sen University from 1994 to 2006 were analyzed retrospectively. According to preoperative NLR, the patients were divided into the low NLR group (NLR≤3.79, n=652) and the high NLR group (NLR>3.79, n=123). The 5-year survival rates of two groups of different TNM stage, different surgical intervention were separately analyzed.
RESULTSThe 5-year survival rates in the low NLR group and high NLR group were 44.0% and 12.2% respectively (P<0.01). In different TNM stages: stage I (97.8% vs 33.3%), stage II (55.4% vs 32.0%), stage IIIA (30.2% vs 11.1%), stage IIIB (15.5% vs 8.3%), stage IV (10.7% vs 2.1%), and in different surgical intervention: D1 curative gastrectomy (93.3% 33.3%), D2 group (51.3% vs 20.4%), D3 group (42.4% vs 10.5%), D4 group (14.3% vs 2.0%), and in palliative operation group (8.3% vs 2.2%). There were significant differences of 5-year survival rate in TNM staging and surgical procedures between the high and low NLR groups (all P<0.05).
CONCLUSIONPreoperative NLR may be a prognostic marker in patients with gastric cancer.
