Modified controlling nutritional status score: A refined prognostic indicator depending on the stage of gastric cancer

The role of controlling nutritional status (CONUT) score in predicting cancer survival remains uncertain. This study aimed to investigate the predictive value of the CONUT score and to develop a more appropriate scoring system beyond CONUT for gastric cancer. We retrospectively reviewed 1307 patients who underwent curative gastrectomy between 2009 and 2015. The CONUT and three modified scores with modified lipid components (L-CONUT: albumin/total lymphocyte count [TLC]/low density lipoprotein, H-CONUT: albumin/TLC/high density lipoprotein, and T-CONUT: albumin/TLC/triglyceride) were calculated. The predictive value of each scoring system on long-term survival was assessed. The values of the four nutritional scores were categorized into four groups (normal, light, moderate, and severe). The CONUT (P
