Share 35 was implemented in 2013 to direct livers to the most urgent candidates by prioritizing Model for End‐Stage Liver Disease (MELD) ≥ 35 patients. We aim to evaluate this policy's impact on costs and mortality. Our study includes 834 wait‐listed patients and 338 patients who received deceased donor, solitary liver transplants at Mayo Clinic between January 2010 and December 2014. Of these patients, 101 (30%) underwent transplantation after Share 35. After Share 35, 29 (28.7%) MELD ≥ 35 patients received transplants, as opposed to 46 (19.4%) in the pre–Share 35 era (P = 0.06). No significant difference in 90‐day wait‐list mortality (P = 0.29) nor 365‐day posttransplant mortality (P = 0.68) was found between patients transplanted before or after Share 35. Mean costs were $3,049 (P = 0.30), $5226 (P = 0.18), and $10,826 (P = 0.03) lower post‐Share 35 for the 30‐, 90‐, and 365‐day pretransplant periods, and mean costs were $5010 (P = 0.41) and $5859 (P = 0.57) higher, and $9145 (P = 0.54) lower post‐Share 35 for the 30‐, 90‐, and 365‐day posttransplant periods. In conclusion, the added cost of transplanting more MELD ≥ 35 patients may be offset by pretransplant care cost reduction. Despite shifting organs to critically ill patients, Share 35 has not impacted mortality significantly. Liver Transplantation 23:11–18 2017 AASLD.

The presence of an intrahepatic cholangiocarcinoma (iCCA) in a cirrhotic liver is a contraindication for liver transplantation in most centers worldwide. Recent investigations have shown that “very early” iCCA (single tumors ≤2 cm) may have acceptable results after liver transplantation. This study further evaluates this finding in a larger international multicenter cohort. The study group was composed of those patients who were transplanted for hepatocellular carcinoma or decompensated cirrhosis and found to have an iCCA at explant pathology. Patients were divided into those with “very early” iCCA and those with “advanced” disease (single tumor >2 cm or multifocal disease). Between January 2000 and December 2013, 81 patients were found to have an iCCA at explant; 33 had separate nodules of iCCA and hepatocellular carcinoma, and 48 had only iCCA (study group). Within the study group, 15/48 (31%) constituted the “very early” iCCA group and 33/48 (69%) the “advanced” group. There were no significant differences between groups in preoperative characteristics. At explant, the median size of the largest tumor was larger in the “advanced” group (3.1 [2.5‐4.4] versus 1.6 [1.5‐1.8]). After a median follow‐up of 35 (13.5‐76.4) months, the 1‐year, 3‐year, and 5‐year cumulative risks of recurrence were, respectively, 7%, 18%, and 18% in the very early iCCA group versus 30%, 47%, and 61% in the advanced iCCA group, P = 0.01. The 1‐year, 3‐year, and 5‐year actuarial survival rates were, respectively, 93%, 84%, and 65% in the very early iCCA group versus 79%, 50%, and 45% in the advanced iCCA group, P = 0.02. Conclusion: Patients with cirrhosis and very early iCCA may become candidates for liver transplantation; a prospective multicenter clinical trial is needed to further confirm these results.

Although short‐term risks of living donor hepatectomy have been well defined, little is known about the longterm impact. We aimed to perform a systematic follow‐up to screen for unanticipated health consequences of liver donation. All donors who were more than 1 year from donation were invited for a systematic evaluation including physical and laboratory assessment, quality of life questionnaire, and magnetic resonance imaging (MRI)/magnetic resonance cholangiopancreatography (MRCP). Those unable to return were offered the questionnaire and laboratory assessment at home. Out of our total of 97 donors, 45 returned for a full assessment and 23 completed labs and survey locally (total n = 68; 70%) after a median of 5.5 years (1.5‐10.9 years) after donation. The only laboratory abnormality was a significant decrease in platelet count (median 198 ×109/L versus 224 ×109/L before donation; P < 0.001), whereas 93% of patients were still above normal limits. No late biliary strictures or other structural abnormalities were found on MRI/MRCP. Liver regeneration was complete. Spleen volume did significantly increase (median 278 cm3 versus 230 cm3 before donation; P < 0.001) without resulting in lowered platelets (P = 0.73). The most common complaints were persistent incisional numbness and changed bowel habits. Seven donors (11%) reported problems obtaining insurance. The vast majority (97%) would have donated again. In conclusion, longterm outcome following liver donation appears satisfactory. None of our donors have developed occult biliary strictures, failure of regeneration, abnormal liver function, or other important health consequences after a median of 5.5 years from surgery. These findings can be used when counseling potential donors in the future. Liver Transplantation 22 934–942 2016 AASLD

In April 2012, the Organ Procurement and Transplantation Network (OPTN) implemented an online explant pathology form for recipients of liver transplantation who received additional wait‐list priority for their diagnosis of hepatocellular carcinoma (HCC). The purpose of the form was to standardize the data being reported to the OPTN, which had been required since 2002 but were submitted to the OPTN in a variety of formats via facsimile. From April 2012 to December 2014, over 4500 explant forms were submitted, allowing for detailed analysis of the characteristics of the explanted livers. Data from the explant pathology forms were used to assess agreement with pretransplant imaging. Explant data were also used to assess the risk of recurrence. Of those with T2 priority, 55.7% were found to be stage T2 on explant. Extrahepatic spread (odds ratio [OR] = 6.8; P < 0.01), poor tumor differentiation (OR = 2.8; P < 0.01), microvascular invasion (OR = 2.6; P < 0.01), macrovascular invasion (OR = 3.2; P < 0.01), and whether the Milan stage based on the number and size of tumors on the explant form was T4 (OR = 2.4; P < 0.01) were the strongest predictors of recurrence. In conclusion, this analysis confirms earlier findings that showed an incomplete agreement between pretransplant imaging and posttransplant pathology in terms of HCC staging, though the number of patients with both no pretransplant treatment and no tumor in the explant was reduced from 20% to <1%. In addition, several factors were identified (eg, tumor burden, age, sex, region, ablative therapy, alpha‐fetoprotein, Milan stage, vascular invasion, satellite lesions, etc.) that were predictive of HCC recurrence, allowing for more targeted surveillance of high‐risk recipients. Continued evaluation of these data will help shape future guidelines or policy recommendations. Liver Transplantation 22 757–764 2016 AASLD.

The evolution of metabolic and cardiovascular disease (CVD) complications after liver transplantation (LT) is poorly characterized. We aim to illustrate the prevalence of obesity and metabolic syndrome (MS), define the cumulative incidence of CVD, and characterize risk factors associated with these comorbidities after LT. A retrospective review of 455 consecutive LT recipients from 1999 to 2004 with an 8‐ to 12‐year follow‐up was performed. Obesity increased from 23.8% (4 months) to 40.8% (3 years) after LT. Increase in body mass index predicted MS at 1 year after LT (odds ratio, 1.1; P < 0.001, per point). CVD developed in 10.6%, 20.7%, and 30.3% of recipients within 1, 5, and 8 years, respectively. Age, diabetes, hypertension, glomerular filtration rate < 60 mL/minute, prior CVD, ejection fraction < 60%, left ventricular hypertrophy, and serum troponin (TN) > 0.07 ng/mL were associated with CVD on univariate analysis. Age (hazard ratio [HR], 1.03; 95% confidence interval [CI], 1.01‐1.06; P = 0.019), diabetes (HR, 1.78; 95% CI, 1.09‐2.92; P = 0.022), prior history of CVD (HR, 2.46; 95% CI, 1.45‐4.16; P < 0.001), and serum TN > 0.07 ng/mL (HR, 1.98; 95% CI, 1.23‐3.18; P = 0.005) were independently associated with CVD in the long term. Smoking history (ever), sex, hyperlipidemia, and serum ferritin levels were not predictive of CVD. Tacrolimus use versus noncalcineurin‐based immunosuppression (HR, 0.26; 95% CI, 0.14‐0.49; P < 0.001) was associated with reduced risk of CVD but not versus cyclosporine (HR, 0.67; 95% CI, 0.30‐1.49; P = 0.322). CVD is common after LT. Independent of MS, more data are needed to identify nonconventional risk factors and biomarkers like serum TN. Curbing weight gain in the early months after transplant may impact MS and subsequent CVD in the long term. Liver Transpl 21:889‐896, 2015. © 2015 AASLD.
