Candidates with hepatocellular carcinoma (HCC) within the Milan criteria (MC) receive standardized Model for End-Stage LIver Disease (MELD) exception points because of the projected risk of tumor expansion beyond the MC. Exception points at listing are meant to be equivalent to a 15% rusj if 90-day mortality, with additional points granted every 3 months, equivalent to a 10% increased morality risk. We analyzed the United Network for Organ Sharing database (January 1, 2005 to May 31, 2009) to compare the 90-day waitlist outcomes of HCC candidates and non-HCC candidates with similar MELD scores. ⋯ In multivariate logistic regression models, HCC candidates had significantly lower 90-day odds of waitlist removal for death or clinical deterioration (P < 0.001). Over time, the risk of waitlist removal for death or clinical deterioration was unchanged for HCC candidates (P = 0.17), whereas it increased significantly for non-HCC candidates. The current allotment of HCC exception points should be re-evaluated because of the stable risk of waitlist dropout for these candidates.

Liver transplantation may be complicated by massive intraoperative bleeding, and red blood cell (RBC) transfusions may be required. The storage duration or age of transfused RBCs has been shown to affect the morbidity and mortality of critically ill, trauma, and cardiac surgery patients. Here we investigate the effect of RBC age on the outcomes of liver transplant patients. ⋯ In conclusion, the RBC age is not associated with infection, organ rejection, or death in liver transplant patients. Patients who receive more blood have an increased risk of death. In a multivariate model, the MELD-Na score was not associated with increased mortality, and this is consistent with previous studies demonstrating that the MELD-Na score is a poor predictor of long-term survival after transplantation.

Comparative Study
Liver transplantation in septuagenarians receiving model for end-stage liver disease exception points for hepatocellular carcinoma: the national experience.
Current liver allocation policy in the United States grants liver transplant candidates with stage T2 hepatocellular carcinoma (HCC) a priority Model for End-Stage Liver Disease (MELD) score of 22, regardless of age. Because advanced age may portend an increase in all-cause mortality after transplantation for any diagnosis, the aim of this study was to examine overall posttransplant survival in elderly patients with HCC versus younger cohorts. Based on Organ Procurement and Transplantation Network data, Kaplan-Meier 5-year survival rates were compared. ⋯ In conclusion, although patients who are 70 years old or older compose a small fraction of transplant recipients in the United States, patients in this group undergoing transplantation for HCC form an even smaller subset. Overall, transplantation in this age group yields outcomes inferior to those for younger cohorts. However, unlike patients who are less than 70 years old and receive MELD exception points, overall liver transplant survival is not affected by HCC at an advanced age.

Acetaminophen-induced acute liver failure (ALF) is a complex multiorgan illness. An assessment of the prognosis is essential for the accurate identification of patients for whom survival without liver transplantation (LT) is unlikely. The aims of this study were the comparison of prognostic models [King's College Hospital (KCH), Model for End-Stage Liver Disease, Sequential Organ Failure Assessment (SOFA), and Acute Physiology and Chronic Health Evaluation II (APACHE II)] and the identification of independent prognostic indicators of outcome. ⋯ The KCH criteria had the highest specificity (83%) but the lowest sensitivity (47%), and the SOFA score had the best discriminative ability (AUC = 0.79). In conclusion, for patients with acetaminophen-induced ALF, the SOFA score performed better than the other prognostic scores, and this reflected the presence of multiorgan dysfunction. A further evaluation of SOFA with the KCH criteria is warranted.
