With the advances in transplant oncology in recent years, the role of liver transplantation has expanded to make curative treatment a possibility for a wider patient population. We highlight strategies in Hong Kong, China that have enabled preoperative prognostication for judicious patient selection, downstaging therapy to definitive treatment, and postoperative therapies that have provided a growing role for liver transplantation in patients with more advanced hepatocellular carcinoma.

Background:Hepatocellular carcinoma (HCC) is a leading cause of cancer-related mortality. While liver transplantation (LT) provides the best long-term survival, it is constrained by organ scarcity and strict criteria. Liver resection (LR) is often the initial treatment for patients with solitary tumors and preserved liver function. The high recurrence rates associated with LR has prompted the exploration of sequential living donor liver transplantation (seq LDLT) after LR as a strategy for HCC patients with high-risk of ***:We analyzed data from 27 adult patients who underwent seq LDLT after LR for HCC at Kaohsiung Chang Gung Memorial Hospital (KCGMH) between June 1994 and December 2023. Patients were selected based on high-risk histopathological features post-LR or as part of downstaging strategy. Outcomes measured included overall survival (OS) and disease-free survival (DFS).Results:Among 765 HCC patients who underwent LDLT, 204 received LR before LDLT, and 27 underwent seqL DLT. Five patients (19%) underwent living donor liver transplantation (LDLT) following LR as a downstaging strategy while the rest received seqL DLT as a preemptive strategy. The median age was 53.5 years with 85%males. Chronic hepatitis B was the predominant underlying disease (74%). The 1-, 3-, and 5-year OS and DFS rates were 100%, 96.0%, 96.0%and 100%, 96.2%, 96.2%, respectively, with two patients experiencing HCC recurrence. One patient died from HCC recurrence. High-risk histopathological features included microvascular invasion (52%), satellite nodules (15%), multiple tumors (26%), tumors> 5 cm(19%), and a total tumor diameter> 10 cm (7%).Conclusions:Seq LDLT offers a promising, tailored approach for managing HCC with adverse histopathologic features. Combining seq LDLT, downstaging strategies, and multidisciplinary treatments can achieve satisfactory OS and DFS in carefully selected patients, highlighting the need for refined criteria to identify the best candidates.
