Portal vein tumor thrombosis (PVTT) is a common phenomenon in hepatocellular carcinoma (HCC). Compared to HCC without PVTT, HCC with PVTT is characterized by an aggressive disease course, worse hepatic function, a higher chance of complications related to portal hypertension and poorer tolerance to treatment. Conventionally, HCC with PVTT is grouped together with metastatic HCC during the planning of its management, and most patients are offered palliative treatment with sorafenib or other systemic agents. As a result, most data on the management of HCC with PVTT comes from subgroup analyses or retrospective series...

INTRODUCTION: The only means of achieving long-term survival in hepatocellular carcinoma is complete tumor resection or liver transplantation. Patients with large hepatocellular carcinomas are currently not considered for liver transplantation. Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) is indicated in selected patients. We present the case of a patient with a huge hepatocellular carcinoma who underwent an ALPPS procedure. PRESENTATION OF CASE: A 57-year-old man initially presented with a tumor measuring 19cm×10cm in the right lobe of the liver...

BACKGROUND AND OBJECTIVES: Hepatic resection is established as the treatment for HCC. However, patients sometimes experience early recurrence of HCC (ER HCC) after curative resection. METHODS: A retrospective analysis was conducted for 193 patients with single HCC who underwent curative liver resection in our medical center between April 2000 and March 2013. We divided the cohort into two groups; early recurrence group (ER G) which experienced recurrence within 6 months after resection, and non-early recurrence group (NER G)...

Hepatocellular carcinoma (HCC) represents one of the leading causes of cancer death and has proved to be highly refractory to treatment. Extensive analysis of the disease has demonstrated that it arises predominantly in response to high-risk etiological challenges, most notably hepatitis virus. However, with evolving vaccination and the obesity epidemic, progressively more cases are associated with underlying metabolic dysfunction. Pathologically diverse forms of HCC are observed, and recent sequencing analysis has defined common events that target well-known cancer pathways including β-catenin/Axin, TP53, and RB/CDKN2A, as well as frequent aberrations in chromatin remodeling factors...

BACKGROUND: Hepatocellular carcinoma (HCC) is still a major health problem, often diagnosed at an advanced stage. The multikinase inhibitor sorafenib is to date the sole approved systemic therapy. Several signalling pathways are implicated in tumour development and progression. Among these pathways, the Ras/MAPK pathway is activated in 50-100% of human HCCs and is correlated with a poor prognosis. The aim of this work was to review the main intracellular mechanisms leading to aberrant Ras pathway activation in HCC and the potential therapeutic implications...

Hepatocellular carcinoma (HCC) is one of the most common tumors affecting man. It is the general feeling that only hepatectomy can give a chance for cure. However, less than 20% of patients can be resected, and other treatment modalities are required. Systemic (chemotherapy, hormonotherapy, immunotherapy) and loco-regional (intratumoral injection of alcohol, intra-arterial chemotherapy embolization, internal radiotherapy) approaches have been developed. In view of the small number of patients, tumor and patient heterogeneity, and difficulties in assessing tumor response, the real place of these treatments is difficult to evaluate...

Hepatocellular carcinoma represents one of the most challenging frontiers in liver surgery. Surgeons have to face a broad spectrum of aspects, from the underlying liver disease to the new surgical techniques. Safe liver resection can be performed in patients with portal hypertension and well-compensated liver function with a 5-year survival rate of 50%, offering good long-terms results in selected patients. With the advances in laparoscopic surgery, major liver resections can be performed with minimal harm, avoiding the wound and leak complications related to the laparotomies...
