Kaplan–Meier estimates of progression-free survival and overall survival according to histologic subtype. (A) The median progression-free survival was 5.0 months in the pancreato-biliary subtype, as compared with 6.1 months in the intestinal subtype. (B) The median overall survival was 10.3 months in the pancreato-biliary group, as compared with 28.3 months in the intestinal group.
