Surgical treatment of gallbladder cancer: An eight-year experience in a single center

Figure 1 Overall and disease-free survival. A: The overall survival curves for each stage are shown; B: The overall survival significantly differed between patients with stage ≤ IIB (blue line) and those with stage ≥ IIIA (red line) disease (P = 0.0080); C: Disease-free survival curves for each stage are shown; D: There was a significant difference in the disease-free survival of patients with stage ≤ IIB (blue line) and patients with stage ≥ IIIA (red line) disease (P = 0.0054).

Figure 2 The median overall and disease-free survival. A: The median overall survival of the 11 deceased patients was 1.66 years (0.16–3.36 years); B: The median disease-free interval of the 15 recurrent patients was 0.79 years (0.12–4.01 years).

Figure 3 Comprehensive flowchart of important points in our patients. Important points (e.g., preoperative diagnosis, surgical treatment, histopathological assessments, stage according to the tumor-node-metastasis classification and prognosis) are summarized. The final stages in each case are shown in parentheses. The outcomes in each case are also shown in parentheses (dead or alive). *Cases with invasive findings of the lymphoid duct and/or nerve plexuses on the histopathological assessment. †Cases with a positive margin at the surgical cut end of the biliary tract. CRT: Chemoradiotherapy; ENBD: Extrahepatic bile duct resection; LC: Laparoscopic cholecystectomy; LN: Lymph node.
