GSTT1 null genotype contributes to hepatocellular carcinoma risk: a meta-analysis.

Studies investigating the association between genetic polymorphism of glutathione S-transferase T1 (GSTT1) and hepatocellular carcinoma (HCC) risk have reported conflicting results. Therefore, we conducted this meta-analysis to provide more precise evidence. Databases including PubMed, Embase, SCOPUS, ISI Web of Science, and Wangfang were searched for relevant studies.

Clinical parameters predicting survival duration after hepatectomy for intrahepatic cholangiocarcinoma.

Background: Currently, the most effective treatment for intrahepatic cholangiocarcinoma (ICC) is complete hepatic tumour excision.

Objective: To identify the clinical parameters associated with survival duration for ICC patients following hepatectomy, and to construct a mathematical model for predicting survival duration.

Methods: Demographic data and clinical variables for 102 patients diagnosed with ICC, who underwent exploratory laparotomy at a single centre from July 1998 to December 2000 and were followed for an average of 24 months, were collected in 2011.

[Extended hepatic pedicle occlusion in major hepatectomy for primary liver cancer].

Objective: To evaluate the influence of extended hepatic pedicle occlusion (HPO) on hepatic ischemic/reperfusion (I/R) injury and intraoperative blood loss in major hepatectomy for primary liver cancer (PLC).

Methods: Between June 2001 and December 2005, a total number of 843 patients with PLC had been operated on. Those whose hepatic pedicle were occluded continuously for or longer than 30 min during hepatectomy were retrospectively reviewed (continuous HPO group) and compared to the patients whose hepatic pedicle were occluded for the same length of time but intermittently (intermittent HPO group).

[Surgical resection of hepatic tumor in segment IXb by anterior transhepatic approach].

Objective: To evaluate the feasibility and the effect of surgical resection of hepatic tumor originated from segment IXb.

Methods: The cases with hepatic tumors in segment IXb who had been operated on between March 2003 and January 2007 were retrospectively reviewed.

Results: A total of 15 tumors in segment IXb, including 13 primary liver cancers and 2 benign tumors with a mean diameter of (4.

[Surgical management of small intrahepatic lesions adjacent to the major vasculature].

Objective: To assess the feasibility and the significance of surgical resection of small intrahepatic lesions adjacent to the major vasculature.

Methods: The results of treatment were retrospectively reviewed in 40 patients who received operation for intrahepatic lesions less than 3 cm in diameter between Jan. 2003 and Dec.

[Surgical treatment for the giant hepatic carcinomas occupying the central part of the liver].

Objective: To evaluate the techniques and the effects of surgical resection of giant hepatic carcinomas which occupied the central part of the liver.

Methods: A retrospective study was carried out of hepatectomies performed for central giant hepatic carcinomas. The hepatic tumors included in this study were hepatocellular carcinomas, cholangiocarcinomas and hepatic metastases which situated in the central part of the liver (segment IV, V, VIII, I) with a diameter of larger than 10 cm and involved hepatocaval confluence, retrohepatic inferior vena cava (IVC) as well as hepatic portal.

Intermittent portal triad clamping in resection of liver tumors involving the hepatocaval confluence.

Objective: To review our experience in and the results of resecting liver tumors involving the hepatocaval confluence under intermittent portal triad clamping (PTC).

Methods: Sixty-eight consecutive patients with liver tumors involving the hepatocaval confluence underwent hepatectomies with liver parenchymal transections under intermittent PTC.

Results: All the tumors were successfully resected under PTC, except for one in which the infrahepatic inferior vena cava was concomitantly occluded in addition to PTC.

[Surgical treatment of hepatocellular carcinoma with tumor thrombus in the inferior vena cava].

Objective: To clarify the proper surgical procedure of treating hepatocellular carcinoma (HCC) with a tumor thrombus in the inferior vena cava (IVC).

Methods: Four patients with HCC with a tumor thrombus in the IVC underwent hepatectomy and thrombectomy. Following hepatectomy, tumor thrombus was removed by incising the wall of the IVC in 3 patients and from the hepatic vein in one patient.
