However, the correlation between preoperative osteopenia and the prognosis of gastric cancer (GC) remains unclear. The aim of this study was to reveal the importance of preoperative osteopenia as a prognostic factor in patients undergoing gastrectomy for GC. Patients and Methods: We enrolled 251 patients who had undergone curative surgery for histopathologically diagnosed gastric adenocarcinoma from January 2008 to December 2012. BMD was calculated as the average pixel density (Hounsfield units) within a circle of the mid-vertebral core at the bottom of the 11th thoracic vertebra on preoperative computed tomography. Results: Osteopenia had a high area under the curve and predictive value for both overall survival (OS) and disease-specific survival (DSS). The study cohort was categorized into an osteopenia group and non-osteopenia group based on the optimal BMD cutoff values for OS (157.5) and DSS (195) determined by receiver operating characteristic analysis. The multivariate analysis revealed that OS (hazard ratio=3.607, p<0.001) and DSS (hazard ratio=2.797, p=0.03) were significantly worse in patients with than without preoperative osteopenia. Conclusion: Preoperative osteopenia is associated with poor OS and DSS in patients undergoing gastrectomy for GC.
