Management of Hepatocellular Carcinoma in the Setting of Liver Cirrhosis

Cirrhosis is an increasing cause of morbidity and mortality in more developed countries, being the 14th most common cause of death worldwide. Hepatocellular carcinoma (HCC) consists a significant health issue worldwide, responsible for more than 1 million deaths annually. The incidence and mortality rates vary across different geographical areas. Between 60 and 90% of HCC patients already have liver cirrhosis, attributed mainly to chronic hepatitis B and C, alcohol abuse, and non-alcoholic fatty liver disease (NASH). The surgical management of HCC in the setting of liver cirrhosis with curative intent includes liver resection, ablation or microwave coagulation, and liver transplantation (LT). Liver resection in a cirrhotic liver with HCC is associated with lower survival rates compared with liver transplantation (LT), depending on the diseases’ stage but on the contrary liver resection could be potentially offered in a larger population compared to liver transplantation. One of the biggest limitations of liver resection is the risk of tumor recurrence, which is high, and it may exceed 70% 5 years after the procedure. Liver transplantation is considered the best treatment for hepatocellular carcinoma at early stages because it removes the tumor as well as the underlying cirrhotic liver

Bilateral Morgagni Hernia: Primary Repair without a Mesh

We present a case of bilateral Morgagni hernia in a 68-year-old male with an intermittent history of progressive onset of breath shortness and occasional cardiac arrhythmias. Diagnosis was made by clinical examination and the findings in a plain chest radiograph and was confirmed by computed tomography scan. The patient was operated electively and subjected to a transabdominal approach. A bilateral subcostal incision revealed a large right side anterior diaphragmatic defect with a hernia containing the ascending colon, the majority of the transverse colon and a huge amount of omentum. Also a second smaller defect was found on the left side with no hernia inside. After large bowel and omentum had been taken down to the peritoneal cavity, both defects were primarily closed using interrupted nylon sutures without the use of a mesh. The patient recovered very well, had an uneventful postoperative course and was released on the 5th postoperative day. 15-month follow-up failed to reveal any signs of recurrence

Minimally Invasive Surgery for Hepatocellular Carcinoma; Latest Advances

Surgical resection is the gold standard for hepatocellular carcinoma management for early stages of the disease. With advances in technology and techniques, minimally invasive surgery provides a great number of advantages for these patients during their surgery and for their post-operative care. The selection of patients following a multi-disciplinary approach is of paramount importance. Adding to this, the developments in laparoscopic instruments and training, as well as the promising advantages of robotic surgery along with other forms of technology, increase the pool of patients that can undergo operation safely and with good results worldwide. We review results from great centres worldwide and delineate the accurate multi-disciplinary approach for this

Molecular Signalling in Hepatocellular Carcinoma: Role of and Crosstalk among Wnt/β-Catenin, Sonic Hedgehog, Notch and Dickkopf-1

Hepatocellular carcinoma is the sixth most common cancer worldwide. In the majority of cases, there is evidence of existing chronic liver disease from a variety of causes including viral hepatitis B and C, alcoholic liver disease and nonalcoholic steatohepatitis. Identification of the signalling pathways used by hepatocellular carcinoma cells to proliferate, invade or metastasize is of paramount importance in the discovery and implementation of successfully targeted therapies. Activation of Wnt/β-catenin, Notch and Hedgehog pathways play a critical role in regulating liver cell proliferation during development and in controlling crucial functions of the adult liver in the initiation and progression of human cancers. β-catenin was identified as a protein interacting with the cell adhesion molecule E-cadherin at the cell-cell junction, and has been shown to be one of the most important mediators of the Wnt signalling pathway in tumourigenesis. Investigations into the role of Dikkopf-1 in hepatocellular carcinoma have demonstrated controversial results, with a decreased expression of Dickkopf-1 and soluble frizzled-related protein in various cancers on one hand, and as a possible negative prognostic indicator of hepatocellular carcinoma on the other. In the present review, the authors focus on the Wnt/β-catenin, Notch and Sonic Hedgehog pathways, and their interaction with Dikkopf-1 in hepatocellular carcinoma
