In 2024, a nationwide conflict between the South Korean government and the medical community, the medical-policy conflict, profoundly impacted healthcare delivery. This study aimed to evaluate the changes in the management of hepatocellular carcinoma (HCC) following this crisis. We analyzed retrospective real-world data from university hospitals in the Seoul Metropolitan Area, supplemented with national healthcare data from the Health Insurance Review and Assessment Service. The analytical variables included changes in workforce composition, initial treatment modalities, HCC stage distribution, quality indicators for HCC care, regional and institutional variations in care delivery, and liver transplantation (LT) volume. A comparison between 2023 and 2024 revealed a marked decline in the number of medical trainees, a rise in the proportion of physician assistants, a 28.9% reduction in newly initiated HCC treatments, and an increased rate of stage IV diagnoses. Several quality indicators, including rates of multidisciplinary care and patient education, declined. The volume of LTs decreased by approximately 20% nationwide, with some regions ceasing LT procedures. The results suggest that serious disruptions occurred in HCC care following the conflict. The significant decrease in initial treatment and number of LT procedures, more advanced stages at diagnosis, and declining quality metrics indicate the emergence of healthcare gaps. Without the recovery of the clinical workforce and the reestablishment of a stable healthcare delivery system, the management of serious diseases such as HCC will remain structurally vulnerable. National-level efforts are urgently required to address regional disparities and restore essential medical services.

This survey aimed to collect expert opinions from multidisciplinary specialists involved in the management of hepatocellular carcinoma (HCC) in Korea regarding real-world criteria for systemic therapy indications. In response to discrepancies between national reimbursement policies and clinical decision-making, members of the Korean Liver Cancer Association and Korean Association for the Study of the Liver participated in a web-based survey from February 4 to 14, 2025. A total of 89 respondents, primarily experienced clinicians, provided their views on major clinical scenarios including infiltrative HCC, bilobar multifocal disease, huge tumors, vascular invasion, extrahepatic metastasis, and transarterial chemoembolization (TACE) refractoriness. There was high agreement for including infiltrative HCC (69.7%), suspected portal vein invasion (70.8%), and TACE refractoriness (82.0%) as systemic therapy indications. TACE refractoriness, in particular, aligns with current guideline definitions. Additionally, over half of respondents (51.7%) supported extrahepatic metastasis under similar conditions. Notably, multidisciplinary discussion was emphasized across scenarios, but many respondents also favored allowing primary physician discretion in select cases. This report provides consolidated expert input to inform future updates to reimbursement policies and promote alignment with real-world clinical practice. These findings may help bridge the gap between national coverage criteria and clinical decision in systemic therapy for HCC.
Backgrounds/Aims In hepatocellular carcinoma (HCC), which exhibits high mortality and recurrence rates globally, the traits of cancer stem cells (CSCs) that significantly influence recurrence and metastasis are not well understood. CSCs are self-renewing cell types identified in most liquid and solid cancers, contributing to tumor initiation, growth, resistance, recurrence, and metastasis following chemo-radiotherapy or trans-arterial chemoembolization therapy.
Methods CSCs are classified based on the expression of cell surface markers such as CD133, which varies depending on the tumor type. Proteomic analysis of liver cancer cell lines with cancer stem cell potential and HCC cancer cell lines lacking stem cell propensity was conducted to compare and analyze specific expression patterns.
Results Proteomic profiling and enrichment analysis revealed higher expression of the calcium-binding protein S100 family in CD133+ Huh7 cells than in CD133- or wild-type cells. Furthermore, elevated expression of S100 family members was confirmed in an actual CD133+ liver cancer cell line via protein-protein network analysis and quantitative polymerase chain reaction (qPCR).
Conclusion The S100 family members are not only new markers of cancer stem cells but will also assist in identifying new treatment strategies for CSC metastasis and tumor advancement.
Approximately 80% of hepatocellular carcinoma (HCC) cases arise in sub-Saharan Africa and Eastern Asia, following a similarly high prevalence of chronic hepatitis B virus (HBV) carriers in these regions. The etiology and epidemiology of HCC have recently changed worldwide. Although HBV infection is the main contributor to HCC development, a slow but continuous decline in HBV infection rates has been reported since 1990. Owing to the widespread use of direct-acting antivirals, the incidence of hepatitis C virus-related HCC has remarkably decreased in Japan and European countries. In Korea, Taiwan, and Singapore, the incidence of HBV-related HCC has significantly decreased owing to vaccination against HBV. Globally, while HBV accounted for more than half of HCCs in 1990, this had decreased to 42% in 2019. In contrast, the proportion of patients with alcoholic- and nonalcoholic steatohepatitis (NASH) increased from 13% to 18% and from 5% to 6%, respectively. NASH-related HCC has characteristics that differ from those of virus-associated HCC. Compared with other etiologies, patients with NASHassociated HCC are older, have a higher body mass index, and have higher rates of type 2 diabetes mellitus, hypertension, hyperlipidemia, and cardiovascular disease. Nonalcoholic fatty liver disease (NAFLD)-associated HCC is also known to develop in the absence of cirrhosis, unlike alcohol-related and autoimmune liver diseases. Because patients with NAFLD usually have diabetes or obesity, surveying this population is challenging. Optimal selection of the target population and surveillance tools among patients with NAFLD needs to be determined.

Background/Aim Despite the increasing proportion of elderly patients with hepatocellular carcinoma (HCC) over time, treatment efficacy in this population is not well established.
Methods Data collected from the Korean Primary Liver Cancer Registry, a representative cohort of patients newly diagnosed with HCC in Korea between 2008 and 2017, were analyzed. Overall survival (OS) according to tumor stage and treatment modality was compared between elderly and non-elderly patients with HCC.
Results Among 15,186 study patients, 5,829 (38.4%) were elderly. A larger proportion of elderly patients did not receive any treatment for HCC than non-elderly patients (25.2% vs. 16.7%). However, OS was significantly better in elderly patients who received treatment compared to those who did not (median, 38.6 vs. 22.3 months; P<0.001). In early-stage HCC, surgery yielded significantly lower OS in elderly patients compared to non-elderly patients (median, 97.4 vs. 138.0 months; P<0.001), however, local ablation (median, 82.2 vs. 105.5 months) and transarterial therapy (median, 42.6 vs. 56.9 months) each provided comparable OS between the two groups after inverse probability of treatment weighting (IPTW) analysis (all P>0.05). After IPTW, in intermediate-stage HCC, surgery (median, 66.0 vs. 90.3 months) and transarterial therapy (median, 36.5 vs. 37.2 months), and in advanced-stage HCC, transarterial (median, 25.3 vs. 26.3 months) and systemic therapy (median, 25.3 vs. 26.3 months) yielded comparable OS between the elderly and non-elderly HCC patients (all P>0.05).
Conclusions Personalized treatments tailored to individual patients can improve the prognosis of elderly patients with HCC to a level comparable to that of non-elderly patients.

Background/Aim The profile of patients with hepatocellular carcinoma (HCC) has changed globally; the role of etiology in predicting prognosis of HCC patients remains unclear. We aimed to analyze the characteristics and prognosis of Korean patients with HCC according to disease etiology.
Methods This retrospective observational study included patients diagnosed with HCC between 2010 and 2014 in a single center in Korea. Patients with HCC aged <19 years old, had coinfection with other viral hepatitis, had missing follow-up data, were Barcelona Clinic Liver Cancer stage D, or died before 1 month were excluded.
Results A total of 1,595 patients with HCC were analyzed; they were classified into the hepatitis B virus (HBV) group (1,183 [74.2%]), hepatitis C virus (HCV) group (146 [9.2%]), and non-B non-C (NBNC) group (266 [16.7%]). The median overall survival of all patients was 74 months. The survival rates at 1, 3, and 5 years were 78.8%, 62.0% and 54.9% in the HBV group; 86.0%, 64.0%, and 48.6% in the HCV group; and 78.4%, 56.5%, and 45.9% in the NBNC group, respectively. NBNC-HCC has a poorer prognosis than other causes of HCC. Survival was significantly longer in the HBV group with early-stage HCC than in the NBNC group. Furthermore, survival was shorter in patients with early-stage HCC and diabetes mellitus (DM) than in those without DM.
Conclusions The etiology of HCC affected clinical characteristics and prognosis to some extent. NBNC-HCC patients showed shorter overall survival than viral-related HCC patients. Additionally, the presence of DM is an additional important prognostic factor in patients with early-stage HCC.

Hepatocellular carcinoma (HCC) with distant metastasis is an absolute contraindication for liver transplantation (LT). However, it is still unclear whether LT is feasible or acceptable in such patients, albeit after being treated with a multidisciplinary approach and after any metastatic lesion is ruled out. We report one such successful treatment with living donor LT (LDLT) after completely controlling far-advanced HCC with inferior vena cava tumor thrombosis and multiple lung metastases. The patient has been doing well without HCC recurrence for eight years since LDLT. The current patient could be an anecdotal case, but provides a case for expanding LDLT indications in the context of advanced HCC and suchlike.

Hepatocellular carcinoma (HCC) primarily originates in the liver with hepatic differentiation. However, HCCs are not homogenous, and approximately 35% of HCC cases are classified as histopathological variants that present distinct pathologic characteristics. In particular, the lymphocyte-rich variant is the rarest subtype accounting for less than 1% of HCCs, which is not well known to date about molecular features and pathophysiology. Herein, we present a case of a patient who was suspected of metastatic liver cancer and confirmed as lymphocyte-rich HCC pathologically. A 78-year-old woman who underwent a right hemicolectomy for colon cancer was referred to our hospital for a newly detected liver mass. We could not make a decision because of insufficient evidence for diagnosis from imaging studies. After resection, we found that it was a lymphocyte-rich HCC. The pathologic features and prognostic trends of this subtype are also discussed.

Background/Aims Programmed death receptor 1 (PD-1) is a promising new target for treatment of patients with hepatocellular carcinoma (HCC). A high expression level of programmed death-ligand 1 (PD-L1) is a possible prognostic indicator for poor outcome in other malignancies. Here, we investigated the clinical significance of PD-1 and PD-L1 in patients with HCC.
Methods We enrolled patients with HCC who underwent surgical resection at Severance Hospital between 2012 and 2017 and investigated the levels of PD-L1 in HCC tissues (tPD-L1) and PD-L1/PD-1 in serum (sPD-L1/sPD-1). We also aimed to determine whether expression levels correlated with clinical and histological features.
Results A total of 72 patient samples were analyzed. The median sPD-L1 and sPD-1 levels were 25.72 and 341.44 pg/mL, respectively. A positive correlation was detected between tPD-L1 and sPD-1 levels (R2=0.426, P<0.001). The median sPD-1 level increased linearly with tPD-L1 score (P=0.002). During the follow-up period, HCC recurred in eight (11.1%) patients and liverrelated mortality occurred in eight (11.1%) patients. Higher sPD-L1 levels (≥19.18 pg/mL) tended to be associated with liver-related mortality (hazard ratio 6.866; 95% confidence interval, 0.804-58.659, P=0.078). sPD-1 levels of patients treated with nivolumab as a second-line therapy changed serially, and a >50% reduction in sPD-1 levels was observed immediately after nivolumab administration. However, sPD-1 level was not associated directly with prognosis in patients with advanced HCC.
Conclusions The results demonstrated that PD-L1 and PD-1 levels changed according to the immunotherapy. However, no significant association with clinical outcome in patients with HCC was detected.

Liver transplantation for patients with hepatocellular carcinoma (HCC) within the Milan criteria
generally yields a 4-year overall survival rate of 75% and 4-year recurrence free survival rate of 83%.
But, many HCC patients present with the disease beyond the Milan criteria. On the other hands, the
overall survival of patients with advanced HCC with portal vein invasion is very poor. We report a
case of successful living donor liver transplantation for advanced HCC with portal vein invasion by
down-staging through radioembolization, hepatic arterial infusion chemotherapy, and stereotactic
body radiation therapy.
Surgical resection is mainstay treatment of hepatocellular carcinoma (HCC). However, its
prognosis is poor, because of the high incidence of HCC recurrence (cumulative 5-year HCC
recurrence rate of 70-80%). The most common site of HCC recurrence is the remnant liver, and
extrahepatic recurrence occurs in 6.7-13.5% of patients. Because the tumor characteristics in
extrahepatic recurrence are usually multiple and aggressive, the optimal treatment modality
has not yet been determined. We report a case of complete remission and long term survival
over 60 months in patient with extrahepatic metastasis after curative resection of HCC
by aggressive treatment, which include lung resection for lung metastasis, radiotherapy
for mediastinal lymph node metastasis, and systemic chemotherapy.
Background/Aims Hepatocellular carcinoma (HCC) with Barcelona Clinic Liver Cancer (BCLC)
intermediate stage includes a highly heterogeneous population. Here, we aimed to subclassify
hepatocellular carcinoma with BCLC intermediate stage for better prognostification. Methods Between 2003 and 2008, 325 patients who were newly diagnosed as HCC with
BCLC intermediate stage were considered eligible. Tumor factor and liver function were used
for sub-classification. Overall survival (OS) was analyzed using Kaplan-Meier method with a
comparison by log-rank test. Results A total of 325 patients with intermediate stage HCC were analyzed. Patients with
tumor size ≥7 cm, tumor number ≥4 and Child-Pugh class B had the worse OS compared
to those with tumor size <7 cm, tumor number <4 and Child-pugh class A, respectively (all
P<0.05). These three variables affected the OS independently from multivariate Cox regression
analysis (all P<0.05). So, using these three variables, patients were finally sub-classified as
those with fulfilling none of three factors (B-a), one of three factors (B-b), two of three factors
(B-c) and all of three factors (B-d) with the median OS of 39.2, 20.6, 12.0 and 8.3 months with
statistical significances (all P<0.05 between B-a and B-b, between B-b and B-c, and between
B-c and B-d), respectively. Conclusions Sub-classification of HCC with BCLC intermediate stage may be useful in not only
prognostification but also guidance of treatment strategies. (J Liver Cancer 2016;16:17-22)
Sorafenib, the first-approved molecular targeted agent (MTA), is actively used in patients with
advanced hepatocellular carcinoma (HCC) worldwide. Accumulating experiences suggest
that the efficacy of this drug is modest and the adverse events are not minimal, although
those are manageable. Given that newer drugs targeting various molecules involved in
hepatocarcinogenesis have been failed to show efficacy compared with sorafenib, the
perspectives regarding development of novel MTA appear to be gloomy. Nonetherless, it is
necessary to maximize the efficacy of sorafenib by combining this drug with locoregional
therapies and by finding biomarkers predicting the outcomes of patients treated with
sorafenib. A series of data indicate that combining sorafenib and locoregional therapies
including transarterial chemoemolization could improve patients outcome. Unfortunately,
there has been no biomarkers identified which could predict the response to sorafenib. Global
investigation of therapeutic decisions in HCC and of its treatment with sorafeNib (GIDEON)
is a global, non-interventional, observational study to evaluate the safety and efficacy of
sorafenib, particularly in patients with Child-Pugh B. The final report of GIDEON study is going
to be published soon, and the Korean GIDEON data suggest that sorafenib in patients with
decreased liver function might be safe and effective as in patients with Child-Pugh A. The way
to conquer HCC using molecular approach is still long and the era of immune-oncology seems
to get started. (Journal of Liver Cancer 2016;16:12-16)
Hepatocellular carcinoma (HCC) is one of the cancers with poor prognosis. However, surgical
resection is the treatment of choice as curative aim for early HCC with preserved liver function.
A 5 year survival rate after curative resection is over 50%. We experienced a case of rapidly
recurred HCC with bone metastasis after surgical resection. In our case, microscopically
microvessel invasion was present after resection. Microvascular invasion (MVI) is an important
factor to influence survival and/or HCC recurrence. So we suggested the patients with MVI
need to follow up intensively and adjuvant therapy may be considered.
Yttrium-90 radioembolization has emerged as a novel therapy for hepatocellular carcinoma
(HCC) of intermediate or advanced stage. Yttrium-90 has characteristics of short half-life and
tissue penetration depth. Potent anti-cancer effect by this isotope enables to kill the tumor
for 6 months after administration. Although transarterial chemoembolization (TACE) is the
standard modality for multinodular HCC without vascular invasion, big size or numerous nodules
does not allow enough treatment effect of TACE. Post-embolization syndrome resulting
poor quality of life, liver dysfunction and hepatic arterial damage are other pitfalls of TACE.
In several studies, radioembolization showed survival comparable to TACE, shorter hospital
stay and less treatment sessions. In advanced HCC with portal vein invasion, radioembolization
demonstrated similar or better survival compared with sorafenib. The atrophy of lobe
treated by radioembolization and hypertrophy in the contralateral lobe can be called radiation
lobectomy, which makes it possible to perform a following curative therapy. The role of
radioembolization in unresectable HCC in terms of downstaging or bridge to transplantation
needs to be further studied. Radioembolization is contraindicated in HCC patients with main
portal vein occlusion and with poor liver function. The International guidelines for HCC have
some limitations and thus rooms for radioembolization to be incorporated.
