OBJECTIVE To summarize the current world position on laparoscopic liver surgery. SUMMARY BACKGROUND DATA Multiple series have reported on the safety and efficacy of laparoscopic liver surgery. Small and medium sized procedures have become commonplace in many centers, while major laparoscopic liver resections have been performed with efficacy and safety(More)
BACKGROUND Patients undergoing liver transplantation for hepatocellular carcinoma within the Milan criteria (single tumour </=5 cm in size or </=3 tumours each </=3 cm in size, and no macrovascular invasion) have an excellent outcome. However, survival for patients with cancers that exceed these criteria remains unpredictable and access to transplantation(More)
BACKGROUND It is a challenge to identify patients who, after undergoing potentially curative treatment for hepatocellular carcinoma, are at greatest risk for recurrence. Such high-risk patients could receive novel interventional measures. An obstacle to the development of genome-based predictors of outcome in patients with hepatocellular carcinoma has been(More)
UNLABELLED Although HCC is the third-leading cause of cancer-related deaths worldwide, there is only an elemental understanding of its molecular pathogenesis. In western countries, HCV infection is the main etiology underlying this cancer's accelerating incidence. To characterize the molecular events of the hepatocarcinogenic process, and to identify new(More)
BACKGROUND & AIMS Small liver nodules approximately 2 cm are difficult to characterize by radiologic or pathologic examination. Our aim was to identify a molecular signature to diagnose early hepatocellular carcinoma (HCC). METHODS The transcriptional profiles of 55 candidate genes were assessed by quantitative real-time reverse-transcription polymerase(More)
Hepatocellular carcinomas represent the third leading cause of cancer-related deaths worldwide. The vast majority of cases arise in the context of chronic liver injury due to hepatitis B virus or hepatitis C virus infection. To identify genetic mechanisms of hepatocarcinogenesis, we characterized copy number alterations and gene expression profiles from the(More)
BACKGROUND & AIMS Hepatocellular carcinoma (HCC) recurs in approximately 70% of cases after resection. Vascular invasion by tumor cells can be classified as gross or microscopic (microvascular invasion [mVI]) and is a risk factor for recurrence. We examined a large cohort of patients with HCC who were treated by resection to identify features of mVI that(More)
UNLABELLED Current guidelines recommend surgical resection as the primary treatment for a single hepatocellular cancer (HCC) with Child's A cirrhosis, normal serum bilirubin, and no clinically significant portal hypertension. We determined how frequently guidelines were followed and whether straying from them impacted survival. BRIDGE is a multiregional(More)
Hepatocellular carcinoma (HCC) generally develops as a consequence of underlying liver disease, most commonly viral hepatitis. The development of HCC follows an orderly progression from cirrhosis to dysplastic nodules to early cancer development, which can be reliably cured if discovered before the development of vascular invasion (typically occurring at a(More)
BACKGROUND The incidence (0.6% to 1.3%) of primary hepatolithiasis (PHL), also known as Oriental cholangiohepatitis, is increasing in Western countries and the treatment remains challenging. We analyzed the outcomes of patients undergoing hepatic resection (HR) for PHL at a single Western center. STUDY DESIGN The records of all patients undergoing HR for(More)
