However, the expansion of indications is going to worsen the chronic scarcity of organs, and new strategies are needed to enlarge the donor pool. A possible source of organs could be developing split liver transplantation programs. We propose to refer donors aged 18-50 years unsuitable for pediatric patients and donors aged 50-60 years for split evaluation. This will generate new small left lateral grafts that can be used for resection and partial liver segment II-III transplantation with delayed total hepatectomy procedures, based on a national waiting list specifically for non-HCC oncologic patients. Centralized imaging review will streamline the donor-recipient matching process and address organizational challenges. Additionally, adopting an ex situ splitting technique during hypothermic oxygenated machine perfusion could further enhance logistical efficiency and improve graft viability. The proposed protocol (ALERT 50) will therefore promote the development of oncologic indications without affecting the standard waiting list and without competing with urgent or pediatric patients.</p>","PeriodicalId":18072,"journal":{"name":"Liver Transplantation","volume":" ","pages":""},"PeriodicalIF":4.7,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143007925","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Given this trend and the influence of hepatitis C (HCV) treatments, updated data on aging and changing etiologies in older patients with HCC are needed. This study examines age trends, clinical characteristics, and transplant outcomes by comparing older (70+), younger patients with HCC, and patients without HCC. All adult candidates for LT (18+) in the UNOS/OPTN registry (2012-2022) were analyzed and categorized by HCC status and age (<70 or 70+). Regression coefficients compared HCC and non-HCC registrants and recipients by age group. The aging trend among LT registrants was more pronounced in patients with HCC. From 2012 to 2022, the mean age of HCC registrants rose from 58.7 to 62.9, with those aged 70+ increasing from 4.2% to 15.0%. Non-HCC registrants saw minimal change, with a stable mean age of 53 years and a modest rise in those 70+ from 2.1% to 4.7%. HCV prevalence among patients with HCC decreased from 37.5% to 27.4%, while patients without HCC dropped from 14.8% to 5%. Posttransplant outcomes for older HCC recipients remained favorable, with 1-year and 5-year survival rates of 91% and 71%, respectively, comparable to older patients without HCC (87% and 69%). Among over 132,000 LT registrants from 2012 to 2022, the age of HCC candidates increased, with a growing proportion aged 70 and older, while the age and proportion of older adults among non-HCC registrants remained stable. This demographic shift underscores the importance of enhanced frailty assessments to improve outcomes for older patients with HCC.</p>","PeriodicalId":18072,"journal":{"name":"Liver Transplantation","volume":" ","pages":""},"PeriodicalIF":4.7,"publicationDate":"2025-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143007886","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Comprehensive studies assessing outcomes for pediatric candidates for rLT under the modern allocation policy are lacking. Organ Procurement and Transplantation Network data from January 1, 2010, to December 31, 2022, were obtained; exclusion criteria included candidates ≥18 years of age and those listed or transplanted for multiple organs. A total of 7645 children met the inclusion criteria, including 7162 candidates for pLT and 483 candidates for rLT. The candidates for rLT, despite a shorter median waitlist time to transplant (6.5 vs. 54 d for pLT), had significantly higher waitlist dropout rates and worse posttransplant outcomes. Vascular complications were the most common reason for primary graft failure. The small size of the recipient was a significant risk factor. Among those retransplanted, the timing of relisting was significantly associated with outcomes, with those relisted within 30 days from the pLT demonstrating considerably worse outcomes. Our findings emphasize the importance of a center's surgical expertise in performing transplants on small recipients to minimize postoperative complications leading to primary graft failure. Once relisted, the timing of suitable organ availability was vital.
