FIGURE 2. Kaplan-Meier survival curves for patients with pancreatic adenocarcinoma who underwent pancreaticoduodenectomy resulting in an R0 or an R1 resection. Median survival for 300 patients undergoing R0 resection was 27.8 months. Median survival for 60 patients undergoing R1 resection was 21.5 months (P = 0.027 on univariate analysis). On multivariate analysis, an R1 resection did not independently affect survival.
