Survival analysis of ampullary adenocarcinoma stratified by the 3-gene model. a Location and function of the 3-genes with a significant (p < 0.05) association with overall survival. Kaplan-Meier curves for relapse-free (b) and overall survival (c). The solid line represents tumors with a collective gene expression score less than 0.45 that represent the ampullary subset with better OS. The dashed line represents tumors with a collective gene expression score greater than 0.45 that represent the ampullary subset with worse OS
