The MORAL score provides a simple, highly accurate tool for predicting recurrence and risk-stratification pre- and postoperatively.

Bridging LRT in HCC patients within MC does not improve post-LT survival or HCC recurrence in the majority of patients who fail to achieve cPR. The need for increasing LRT treatments and lack of alphafetoprotein response to LRT independently predict post-LT recurrence, serving as a surrogate for underlying tumor biology which can be utilized for prioritization of HCC LT candidates.

Cholestatic hepatitis C virus (HCV) is a rare form of recurrent HCV following liver transplantation (LT) without specific diagnostic criteria. An outcome-based method to improve its diagnosis and a description of its prognosis are needed. All 1-year post-LT protocol liver biopsy samples and biopsy samples initially reported to show cholestatic HCV from patients transplanted with HCV between February 2002 and December 2009 were reviewed for the inflammation grade, the fibrosis stage, and 4 cholestatic HCV features: ductular proliferation, canalicular cholestasis with or without intracellular cholestasis, hepatocyte swelling with or without lobular disarray, and sinusoidal/pericellular fibrosis. We used patient and graft survival to define histological criteria for cholestatic HCV, and compared the clinical features of these patients to those of patients with minimal or significant post-LT fibrosis. One hundred seventy-nine patients were analyzed, the median age was 56 years, and 73% were male. Patients with 3 or more of the 4 cholestatic HCV criteria had significantly worse survival (log-rank P < 0.001) regardless of the fibrosis stage, and this was used as our novel definition of cholestatic HCV. Using this definition, we found that 27 patients (15%) had cholestatic HCV, 53 (30%) had significant fibrosis (stage ≥ 2/4), and 99 (55%) had minimal fibrosis (stage < 2/4). The final model for clinical predictors of cholestatic HCV included donor age [odds ratio (OR) = 1.37 per decade, P = 0.04] and previous rejection (Banff grade ≥ 5; OR = 4.19, P = 0.002). Total bilirubin was the strongest laboratory predictor of cholestatic HCV (area under the curve = 0.93), whereas the HCV viral load was not a significant predictor. The final model of post-LT survival included the pathology group {cholestatic HCV [hazard ratio (HR) = 6.07, P < 0.001] and significant fibrosis (HR = 2.53, P = 0.02)}, donor age (HR = 1.49 per decade, P < 0.001), and cold ischemia time (HR = 1.11 per hour, P = 0.02). In conclusion, we propose diagnostic criteria for cholestatic HCV that include specific criteria (the presence of at least 3 of the 4 histopathological features on biopsy) and other supportive and exclusionary criteria. Older donor age and rejection increase the risk of cholestatic HCV, and an elevation in the total bilirubin level may help to identify these patients. These criteria must be validated prospectively.

Numerous epidemiological studies confirm that the prevalence of obesity and the cardiorenal metabolic syndrome (CRS) is extraordinarily high and that the rates have increased dramatically in the last three decades. In addition, epidemiological data demonstrate that obesity, the CRS, and diabetes are inextricably linked and are all associated with an increased incidence of a number of solid tissue cancers. The mechanisms for this association have been examined, including, but not limited to, higher levels of insulin and free levels of insulin-like growth factor and insulin resistance in obesity and the CRS. Mortality, morbidity, and the associated health care costs which are the link between obesity, the CRS, and diabetes are just beginning to be examined. In addition, we review the advantages of implementing lifestyle and surgical changes to modify obesity, lessening the development of the CRS, diabetes, and associated cancers. Epidemiological data regarding the general mechanisms of the pathogenesis of cancers associated with obesity, the CRS, and diabetes (specifically colon, pancreas, esophageal, liver, breast, prostate, thyroid, and renal carcinomas) are reviewed. The mechanisms by which obesity and other components of the CRS contribute to the pathogenesis of these cancers, such as hormone alterations and insulin-and insulin-like growth factor-dependent pathways of tumor pathogenesis, include the attending roles of inflammation and oxidative stress.
