The Milan criteria have been adopted by United Network for Organ Sharing (UNOS) to preoperatively assess outcome in patients with hepatocellular carcinoma (HCC) who receive orthotopic liver transplantation (OLT). These rely solely on radiographic appearances of the tumor, providing no measure tumor biology. Recurrence rates, therefore, remain around 20% within criteria. neutrophil-lymphocyte ratio (NLR) is an indicator inflammatory status previously established as a prognostic colorectal...
To identify medical predictors of futility in recipients with laboratory Model End-Stage Liver Disease (MELD) scores 40 or more at the time orthotopic liver transplantation (OLT).Although survival benefit for transplant patients highest MELD is indisputable, and economic effort to bring these acuity through OLT presents a major challenge every center.This study was undertaken analyze outcomes undergoing during period February 2002 December 2010. The analysis focused on futile outcome...
To evaluate the effect of pretransplant bridging locoregional therapy (LRT) on hepatocellular carcinoma (HCC) recurrence and survival after liver transplantation (LT) in patients meeting Milan criteria (MC).Pre-LT LRT mitigates tumor progression waitlist dropout HCC within MC, but data its impact post-LT remain limited.Recurrence-free were compared among 3601 MC with without utilizing competing risk Cox regression consecutive from 20 US centers (2002-2013).Compared 747 LT recipients not...
Priority is given to patients with hepatocellular carcinoma (HCC) receive liver transplants, potentially causing significant regional disparities in organ access and possibly outcomes this population. Our aim was assess these by comparing long waiting time regions (LWTR, 5 9) short (SWTR 3 10) analyzing the United Network for Organ Sharing (UNOS) database. We analyzed 6,160 HCC who received exception points 3, 5, 9, 10 from 2002 2012. Data 9 were combined compared data 10. Survival studied...
Objective: The aim of this study was to assess improvements in long-term survival after liver transplant by analyzing outcomes recipients who survived beyond 1 year. Summary Background Data: Gains short-term following transplantation have been gratifying. One-year 1986 66% improved over 92% 2015. However, little is known about why has not seen similar success. Methods: We analyzed 111,568 from 1987 2016 using the Kaplan-Meier method for time-to-event analysis and multivariable Cox...
Background and Aims The Organ Procurement Transplantation Network recently approved liver transplant (LT) prioritization for patients with hepatocellular carcinoma (HCC) beyond Milan Criteria (MC) who are down‐staged (DS) locoregional therapy (LRT). We evaluated post‐LT outcomes, predictors of down‐staging, the impact LRT in beyond‐MC HCC from U.S. Multicenter Transplant Consortium (20 centers, 2002‐2013). Approach Results Clinicopathologic characteristics, overall survival (OS),...
Background and Aims The surge in unhealthy alcohol use during the COVID‐19 pandemic may have detrimental effects on rising burden of alcohol‐associated liver disease (ALD) transplantation (LT) USA. We evaluated effect temporal trends for LT including ALD. Approach Results Using data from United Network Organ Sharing, we analyzed wait‐list outcomes USA through March 1, 2021. In a short‐period analysis, patients listed or transplanted between June 2019, February 29, 2020, were defined as...
The aim of the study was to determine rate, predictors, and impact complete pathologic response (cPR) pretransplant locoregional therapy (LRT) in a large, multicenter cohort hepatocellular carcinoma (HCC) patients undergoing liver transplantation (LT).LRT is used mitigate waitlist dropout for with HCC awaiting LT. Degree tumor necrosis found on explant has been associated recurrence overall survival, but not evaluated study.Comparisons were made among receiving pre-LT LRT (n = 802) without...
With continuing improvements in medical devices and more than a decade since the 2006 United Network for Organ Sharing (UNOS) allocation policy, it is pertinent to assess survival among patients on heart transplantation waiting list, especially given recently approved 2018 UNOS policy.To outcomes transplant list during past 3 decades examine association of ventricular assist (VADs) policy with survival.A retrospective cross-sectional used database perform an analysis 95 323 candidates...
The clinical course of COVID-19 in pediatric solid organ transplant recipients remains ambiguous. Though preliminary experiences with adult have been published, literature centered on the population is limited.
