Objective: To compare the predictive values of eight staging systems for primary liver cancer in the prognosis of combined hepatocellular-cholangiocellular carcinoma (cHCC-CC) patients after surgery., Methods: The clinical data of 54 cHCC-CC patients who underwent hepatectomy or liver transplantation from May 2005 to Augest 2013 in Chinese PLA General Hospital were collected. We evaluated the prognostic value of the Okuda staging system, Cancer of the Liver Italian Program (CLIP) score, French staging system, Barcelona Clinic Liver Cancer (BCLC) staging system, 7th edition of tumour-node-metastasis (TNM) staging system for hepatocellular carcinoma and intrahepatic cholangiocarcinoma (ICC), Japan Integrated Staging (JIS) score, and Chinese University Prognostic Index. The distribution, Kaplan-Meier method, Log-rank test, and area under a receiver operating characteristic curve were used to compare the prognosis-predicting ability of these different staging systems in 54 cHCC-CC patients after surgery., Results: The TNM staging system for ICC and JIS score had a better distribution of cases. The 12-and 24-month survivals of the entire cohort were 65.5% and 56.3%, respectively. A Log-rank test showed that there was a significant difference existing in the cumulative survival rates of different stage patients when using TNM staging system for ICC (stage 1 vs. stage 2, P=0.012; stage 2 vs. stage 3-4, P=0.002), Okuda staging system (stage 1 vs. stage 2, P=0.025), and French staging system (stage A and stage B, P=0.045). The 12-and 24-month area under curve of TNM staging system for ICC, BCLC staging system, JIS score, and CLIP score were 0.836 and 0.847, 0.744 and 0.780, 0.723 and 0.764, and 0.710 and 0.786, respectively., Conclusion: The 7th edition of TNM staging system for ICC has superior prognostic value to other seven staging systems in cHCC-CC patients undergoing surgical treatment.

Background: The resection and reconstruction of the hepatic artery is often required in radical surgery for hilar cholangiocarcinoma. In this study, we report our experience in performing arterioportal shunting as an alternative for the arterial reconstruction., Methods: Four patients with hilar cholangiocarcinoma underwent extended left hepatectomy and caudate lobectomy combined with en bloc resection of the hepatic artery and arterioportal shunting with restriction of the arterial caliber. The efficacy of arterioportal shunting was assessed by computed tomography angiography (CTA)., Results: All the four patients recovered uneventfully without any complications. CTA showed a patent shunt and normal liver regeneration. No signs of portal hypertension were found at one year of follow-up., Conclusions: Arterioportal shunting with restriction of the arterial caliber appears to be a feasible and safe alternative for the microvascular reconstruction after hepatic artery resection in radical surgery for hilar cholangiocarcinoma.

Objective: To summarize the methods, safety and efficiency of surgical resection for hilar cholangiocarcinoma., Methods: The clinical and follow-up data of 48 patients with hilar cholangiocarcinoma underwent surgical resection from January 2003 to December 2007 were analyzed retrospectively. There were 26 male and 22 female, aged from 38 to 72 years old with a mean of 63.6 years old., Results: Perioperative management including percutaneous transhepatic biliary drainage applied in 19 cases and portal vein embolization applied in 2 cases. Eight patients were treated with extrahepatic bile duct resection with or without parital hepatic segment II resection, 10 cases with perihilar hepatic resection (segment IVB, partial V, partial VIII, I), 28 cases with extended hemihepatectomy and 2 cases with central hepatic resection (segment IVB, V, VIII, I). R0 resection rate was 89.5% and the operative mortality was 2.1%. The 1-, 3- and 5-year survival rate were 93.5%, 51.8% and 36.5%, respectively. Patients undergoing extended hepatic resection survived significantly longer than those undergoing partial hepatic resection (P = 0.034)., Conclusions: Extended hepatic resection for hilar cholangiocarcinoma offers good outcomes with an acceptable mortality rate.
