Hepatocellular carcinoma (HCC) is the most common primary liver malignancy and is a leading cause of cancer-related death worldwide. In the United States, HCC is the ninth leading cause of cancer deaths. Despite advances in prevention techniques, screening, and new technologies in both diagnosis and treatment, incidence and mortality continue to rise. Cirrhosis remains the most important risk factor for the development of HCC regardless of etiology. Hepatitis B and C are independent risk factors for the development of cirrhosis. Alcohol consumption remains an important additional risk factor in the United States as alcohol abuse is five times higher than hepatitis C. Diagnosis is confirmed without pathologic confirmation. Screening includes both radiologic tests, such as ultrasound, computerized tomography, and magnetic resonance imaging, and serological markers such as α-fetoprotein at 6-month intervals. Multiple treatment modalities exist; however, only orthotopic liver transplantation (OLT) or surgical resection is curative. OLT is available for patients who meet or are downstaged into the Milan or University of San Francisco criteria. Additional treatment modalities include transarterial chemoembolization, radiofrequency ablation, microwave ablation, percutaneous ethanol injection, cryoablation, radiation therapy, systemic chemotherapy, and molecularly targeted therapies. Selection of a treatment modality is based on tumor size, location, extrahepatic spread, and underlying liver function. HCC is an aggressive cancer that occurs in the setting of cirrhosis and commonly presents in advanced stages. HCC can be prevented if there are appropriate measures taken, including hepatitis B virus vaccination, universal screening of blood products, use of safe injection practices, treatment and education of alcoholics and intravenous drug users, and initiation of antiviral therapy. Continued improvement in both surgical and nonsurgical approaches has demonstrated significant benefits in overall survival. While OLT remains the only curative surgical procedure, the shortage of available organs precludes this therapy for many patients with HCC.
The majority of patients who undergo liver transplantation (LT) spend some time in the intensive care unit during the postoperative period. For some, this is an expected part of the immediate posttransplant recovery period, whereas for others, the stay is more prolonged because of preexisting conditions, intraoperative events, or postoperative complications. In this review, 4 topics that are particularly relevant to the postoperative intensive care of LT recipients are discussed, with an emphasis on current knowledge specific to this patient group. Infectious complications are the most common causes of early posttransplant morbidity and mortality. The common patterns of infection seen in patients after LT and their management are discussed. Acute kidney injury and renal failure are common in post-LT patients. Kidney injury identification, etiologies, and risk factors and approaches to management are reviewed. The majority of patients will require weaning from mechanical ventilation in the immediate postoperative period; the approach to this is discussed along with the approach for those patients who require a prolonged period of mechanical ventilation. A poorly functioning graft requires prompt identification and appropriate management if the outcomes are to be optimized. The causes of poor graft function are systematically reviewed, and the management of these grafts is discussed.
Patients with end-stage lung disease complicated by cirrhosis are not expected to survive lung transplantation alone. Such patients are potential candidates for combined lung-liver transplantation (CLLT), however few reports document the indications and outcomes after CLLT. This is a review of a large single-center CLLT series. Eight consecutive CLLT performed during 2009-2012 were retrospectively reviewed. One patient received a third simultaneous heart transplant. Mean age was 42.5 6 11.5 years. Pulmonary indications included cystic fibrosis (CF) (n 5 3), idiopathic pulmonary fibrosis (n 5 2), a1-antitrypsin deficiency (AATD) (n 5 1) and pulmonary hypertension (n 5 2). Liver indications were CF (n 5 3), hepatitis C (n 5 2), AATD (n 5 1), cryptogenic (n 5 1), and cardiac=congestive (n 5 1). Urgency was reflected by median lung allocation score (LAS) of 41 (36.0-89.0) and median predicted FEV1 of 25.7%. Median donor age was 25 (20-58) years with median cold ischemia times of 147 minutes and 6.1 hours for lung and liver, respectively. Overall patient survival at 30 days, 90 days and 1 year was 87.5%, 75.0% and 71.4% respectively. One patient had evidence of acute lung rejection, and no patients had liver allograft rejection. Early postoperative mortalities (90 days) were caused by sepsis in 2 recipients who exhibited the highest LAS of 69.9 and 89.0. The remaining recipients had a median LAS of 39.5 and 100% survival at 1-year. Median length of stay was 25 days (7-181). Complications requiring operative intervention included bile duct ischemia (n 5 1) and bile leak (n 5 1), ischemia of the bronchial anastomosis (n 5 1), and necrotizing pancreatitis with duodenal perforation (n 5 1). This series reflects a large single-center CLLT experience. Sepsis is the most common cause of death. The procedure should be considered for candidates with LAS < 50. Liver Transpl 20:46-53, 2014.

Orthotopic liver transplantation has emerged as the standard treatment for end-stage liver disease. In the United States, the number of listed patients has tripled in the last two decades. Organ availability during the same period has plateaued at approximately 6000 grafts annually, resulting in a fivefold increase in wait-list mortality. The problem is not specific to the United States; European and Asian registries report similar shortages. Donor pool expansion strategies such as the use of living donors, cadaveric split livers, and "extended criteria donors"; (ECD) are being pursued. Used judiciously, ECD grafts provide an opportunity for addressing the shortage. Although there is no universally accepted definition of ECD, the term generally refers to donor factors predisposing recipients to poor initial graft function and/or increased long-term risk. These factors include advanced donor age, hypernatremia, prolonged warm ischemic time, pressor requirement, and donation after cardiac death. The transplant community is scrutinizing all factors to evaluate the degree of risk they impart on the recipient and the extent to which grafts can be "matched"; to maintain acceptable outcomes. We review the importance of selected factors and the impact of a "matching"; strategy to minimize recipient risk while optimizing graft use.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
