Survival curves for patients who underwent negative-margin (R0) resection of gallbladder cancer with preservation of the extrahepatic bile duct. No patients were lost to follow-up. (a) Overall survival curve. The median survival was not reached. The estimated 3-year survival rate was 78%. (b) Survival curves according to lymph node status. Patients with N1 (n = 6) and Nx (n = 2) disease were pooled. Patients with N0 disease had significantly better survival than patients with N1/Nx disease (P = 0.04). No significant association emerged between survival and depth of tumour invasion. Nx, lymph node status not available in pathology report
