Effects of Location and Extension of Portal Vein Tumor Thrombus on Long-Term Outcomes of Surgical Treatment for Hepatocellular Carcinoma

The role of surgical resection and thrombectomy for hepatocellular carcinoma (HCC) with portal vein tumor thrombus (PVTT) is controversial. This study aimed to evaluate the effects of the location and extent of PVTT on the long-term outcomes of surgical treatment for HCC. A total of 438 patients with HCC and PVTT underwent liver resection with or without thrombectomy. These 438 patients were divided into 2 groups: in group A, PVTT was located in the hepatic resection area or protruded into the first branch of the main portal vein beyond the resection line for <1 cm (286 patients), and in group B, PVTT extended into the main portal vein (152 patients). Concomitant thrombectomy was performed in 147 patients (51.4%) of group A and in all patients of group B. PVTT recurrence within 6 months after surgery in group B was significantly higher than that in group A: 76.9% vs. 11.3%. Remnant liver recurrence within 1 year after surgery was 45.0% in group A and 78.8% in group B. The cumulative 1-, 2-, 3-, and 5-year overall survival rates were 58.7%, 39.9%, 22.7%, and 18.1% for group A and 39.5%, 20.4%, 5.7%, and 0% for group B, respectively. The overall survivals were significantly better in group A than group B (P < .02). Liver resection with thrombectomy yielded better outcomes in the HCC patients with PVTT confined to the first or second branch of the main portal vein compared with PVTT extending into the main portal vein.BackgroundThe role of surgical resection and thrombectomy for hepatocellular carcinoma (HCC) with portal vein tumor thrombus (PVTT) is controversial.

Use of hepatectomy and splenectomy to treat hepatocellular carcinoma with cirrhotic hypersplenism

The aim of this study was to compare the outcome after simultaneous hepatectomy and splenectomy with that after hepatectomy alone for hepatocellular carcinoma with associated hypersplenism.

Long-term outcome of resection of large hepatocellular carcinoma.

The role of hepatectomy in the treatment of large hepatocellular carcinoma (HCC) is still controversial. This retrospective study evaluated whether the long‐term outcome of hepatectomy for large HCC improved over 14 years in one centre.

Chinese experience with hepatectomy for huge hepatocellular carcinoma

The risks and outcome of hepatic resection for huge hepatocellular carcinoma (HCC) are controversial.

Extent of liver resection for hilar cholangiocarcinoma.

The extent of liver resection for hilar cholangiocarcinoma (HC) remains controversial despite extensive studies. The aim of this study was to determine the safety and efficacy of minor and major hepatectomy, selected by predetermined criteria in patients with HC.

Modified technique of hepatic vascular exclusion: effect on blood loss during complex mesohepatectomy in hepatocellular carcinoma patients with cirrhosis

BackgroundHepatic veins remain patent during complete inflow occlusion (CIO) and bleeding from them may continue. Occlusion of the inferior vena cava (ICV) during CIO may reduce blood loss from hepatic veins. This study was designed to compare the overall outcomes after application of CIO with or without occlusion of the ICV below the liver in complex mesohepatectomy for hepatocellular carcinoma (HCC) patients with cirrhosis.Materials and methodsOne hundred and eighteen (118) patients were randomly assigned to CIO or a modified technique of hepatic vascular exclusion (MTHVE). Hemodynamic parameters were evaluated and the amount of blood loss, measurement of liver enzymes, and postoperative progress were recorded.ResultsBlood loss during liver transection in CIO groups was significantly greater than that in MTHVE group (P=0.046). Thus, incidence of blood transfusion was significantly greater in patients of the CIO group (P=0.041). There were no significant differences in liver enzyme changes, bilirubin, or morbidity in the postoperative period between the two groups.ConclusionsCIO with occlusion of the ICV below the liver is a safe, effective, and feasible technique during mesohepatectomy in HCC patients with cirrhosis. Excellent results were obtained with minimized bleeding, limited hepatic function damage, and low rate of postoperative complications.

Role of Mesohepatectomy with or without Transcatheter Arterial Chemoembolization for Large Centrally Located Hepatocellular Carcinoma

Background: The role of preoperative transcatheter arterial chemoembolization (TACE) for resectable hepatocellular carcinoma (HCC) was controversial. Methods: 246 patients with large centrally located HCC underwent mesohepatectomy (MH) and were divided into two groups: group A, 89 patients with preoperative TACE; group B, 157 patients without preoperative TACE. The aim was to evaluate the influence of preoperative TACE on postoperative complications and long-term results of patients with large centrally located HCC. Results: In the 89 patients of the TACE-MH group, a total of 123 (mean 1.4 per patient) preoperative TACEs were performed. The differences in postoperative complications (34.8 vs. 24.2%;p = 0.075) and overall hospital mortality (3.4 vs. 0.6%; p = 0.103) between the two groups were not significant. The postoperative recurrence rate in the remnant liver was higher in the MH group than in the TACE-MH group (79.6 vs. 73.0%), while the extrahepatic metastasis rate in the TACE-MH group was higher than that in the MH group (11.1 vs. 7.0%). Overall 1-, 3-, and 5-year survival rates were 87.1, 62.9, and 46.2%, respectively, for the TACE-MH group, and 82.2, 54.4, and 31.7%, respectively, for the MH group (p = 0.001); 1-, 3-, and 5-year disease-free survival rates were 75.0, 46.2, and 31.8%, respectively, for the TACE-MH group, and 69.6, 38.0, and 16.5%, respectively, for the MH group (p = 0.002). Conclusions: Long-term outcomes of patients with preoperative TACE were improved and the pattern of the recurrences after surgery was altered. The patients with large centrally located HCC could benefit more from this neoadjuvant treatment, although there was some influence of preoperative TACE on postoperative complications.

Alternative management of anatomical right hemihepatectomy using ligation of inflow and outflow vessels without hilus dissection.

Background and Aim:  The conventional method of anatomical right hemihepatectomy (ARHH) requires hilus dissection. We report a method without hilus dissection to minimize intraoperative bleeding.

Surgical treatment of hepatocellular carcinoma with cirrhotic esophageal varices and hypersplenism: a 184 case report

In treating hepatocellular carcinoma (HCC) patients with advanced cirrhosis, one of the most difficult problems is concomitant esophageal varices and hypersplenism. Whether these conditions should be treated surgically in association with HCC resection is still in debate. To elucidate whether esophageal devascularization or splenectomy is beneficial when simultaneously performed with liver resection in HCC patients with both varices and hypersplenism, HCC patients (n = 184) with esophageal varices and hypersplenism received one of the three treatments: simultaneous liver resection and esophageal devascularization (Group I, n = 41); simultaneous liver resection and splenectomy (Group II, n = 61); liver resection only (Group III, n = 82). The incidences of postoperative complications of the three groups were 31.7%, 29.5% and 24.4%, respectively, with no significant difference among them. The 5-year tumor-free survival rates for the group I, group II and group III were 34.1%, 36.1% and 37.8%, respectively. Variceal bleeding caused death by only 4.2% in group I, but by 14.3% in group II and 23.2% in group III. The survival rates in the group I and the group II were comparable to those in the group III, however, the recurrences of postoperative fatal variceal bleeding in group I and group II were significantly lower than those in group III. The results suggest that HCC patients with esophageal varices and hypersplenism should undergo hepatic resection plus esophageal devascularization or splenectomy if radical resection of HCC can be expected.
