Figure 2. OS curves of 17 patients who underwent R0 resection. The 5-year OS rate was significantly better (A) in patients with pancreatic invasion than in those with duodenal invasion (54.5% vs. 0%; P = 0.048) and (B) in patients with differentiated tumors than in those with undifferentiated tumors (68.6% vs. 0%; P = 0.004).
