An educational tool as an aid for making decisions about the initial treatment of gastric cancer.

e14684 Background: Tools for making individualized numerical estimates of outcomes and to provide useful information are revolutionizing medicine. We have produced such a tool for decision making for patients with gastric cancer [GC] for whom neo/adjuvant therapy might be an option to be considered. Methods: We widely reviewed the medical literature and meta-analyses about adjuvant and neoadjuvant treatment for potentially resectable [GC]. We also reviewed the guidelines' statements about what is considered appropriate treatment for patients. In addition we used information about individual prognosis based on information from the SEER registry, the AJCC, and also as supplemented from the medical literature. Results: Examination of the medical literature shows the value of adjuvant chemotherapy and radiation for [GC]. For example, and recent GASTRIC meta-analysis of 31 trials found that a benefit for overall survival (hazard ratio [HR], 0.82; 95% CI, 0.76-0.90) and for disease-free survival (HR, 0.82; 95% ...
