Background The patatin-like phospholipase domain-containing protein 3 (PNPLA3) I148M variant has been implicated in metabolic dysfunction-associated steatotic liver disease (MASLD), but its role in hepatocellular carcinoma (HCC) development is unclear. This study examines the association between the PNPLA3 I148M variant and HCC occurrence.
Methods A total of 562 MASLD patients, with and without HCC, were prospectively and consecutively enrolled at two university-affiliated hospital between June 2024 and June 2025. Genomic DNA was extracted from buccal swabs or liver biopsy samples, and single nucleotide polymorphism (SNP) genotyping was performed to determine the rs738409 genotype at codon 148 of PNPLA3. The histological grade of HCC was assessed using the Edmondson-Steiner (ES) grading system in patients who underwent core-needle liver biopsy.
Results Among 474 non-HCC patients, the GG genotype was found in 39.9%, GC in 37.1%, and CC in 23.0%. In 88 HCC patients, these frequencies were 45.5%, 36.4%, and 18.2%, respectively. No significant differences in GG genotype distribution were observed between HCC and non-HCC groups (P = 0.509), nor in subgroups by sex, age, obesity status, cirrhosis status, Fibrosis-4 Index, or Liver Stiffness Measurement. However, among HCC patients with histological grading, the GG genotype was significantly associated with higher ES grades (P = 0.0076).
Conclusions The PNPLA3 I148M GG genotype was not significantly associated with increased HCC occurrence in Korean MASLD patients within the present cohort. Although the GG genotype is known to play a role in development and progression of MASLD, further studies are warranted to clarify its contribution to tumor initiation and dedifferentiation.

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.
Hepatocellular carcinoma (HCC) is a cytotoxic chemotherapy-resistant tumor and most HCCs arise in a background of liver cirrhosis of various causes. Although the IMBrave150 trial showed remarkable advancements in the treatment of unresectable HCC with atezolizumab plus bevacizumab (AteBeva), therapeutic outcomes were unsatisfactory in more than half of the patients. Accordingly, many ongoing trials combine conventional modalities with new drugs such as immune checkpoint inhibitors for better treatment outcomes, and they are expected to benefit patients with limited responses to conventional treatment. Here, two patients with advanced stage HCC with preserved liver function and good performance status showed partial response after treatment with combination or sequential therapy of AteBeva, hepatic arterial infusion chemotherapy, radiation therapy, and transarterial chemoembolization. These findings indicate the efficacy of multidisciplinary treatment against advanced HCC. Additional studies are required to establish optimal treatment strategies.

Background/Aims Lenvatinib was recently proven to be non-inferior to sorafenib in treating unresectable hepatocellular carcinoma (HCC) in a phase-3 randomized controlled trial. In this study, we investigated whether the response to lenvatinib was affected by tumor immunogenicity.
Methods Between May 2019 and April 2020, nine patients with intermediate-to-advanced HCC, who were treated with lenvatinib after liver biopsy, were enrolled. Immunohistochemical staining and multi-color flow cytometry were performed on specimens obtained from liver biopsy.
Results Among the nine patients enrolled, four showed objective responses (complete responses+partial responses). Immunohistochemical staining for CD3, CD68, and programmed cell death ligand 1 (PD-L1) demonstrated that patients with objective responses showed marked infiltration of T cells and PD-L1-expressing macrophages in intra-tumoral and peri-tumoral tissues compared to those without objective responses. A significant difference in the numbers of infiltrated T cells, both in the intra-tumoral (P<0.01) and peri-tumoral regions (P<0.05), were identified between responders and non-responders. Regarding the number of infiltrated macrophages, no significant difference was found between the responders and non-responders, although the number of PD-L1-expressing tumor-associated macrophages was significantly higher in responders than that in non-responders (P<0.05).
Conclusions Tumor immunogenicity, as indicated by T cell and PD-L1-positive macrophage infiltration, affects lenvatinib response in unresectable HCC.

Despite recent advances in the treatment of hepatocellular carcinoma (HCC), the prognosis
of patients with extrahepatic metastasis from HCC still remains dismal. The current study
presents a case of HCC that was metastatic to the pelvis and describes successful treatment
with multidisciplinary approach to the skeletal metastasis. The patient was a 67-year-old
male who presented with right pelvic pain 28 months following right hepatectomy for HCC.
Computed tomography and magnetic resonance imaging indicated a solitary bone metastasis
without intrahepatic recurrence. Complete response was achieved with multidisciplinary
management including sorafenib, transarterial embolization, surgery to remove the
metastatic mass and radiotherapy after surgery. A post-operative follow-up 15 months later
found that the patient remained in good health with maintained complete response. This case
suggests that a multidisciplinary approach can achieve long-term cancer-free survival and
prolonged life expectancy beyond palliative care for patients with solitary bone metastasis
after curative surgery for HCC.
Background/Aims Metronomic (MET) chemotherapy is a treatment characterized by
frequent infusion of low doses of chemotherapeutic agent without extended break. The aim
of this study is to evaluate the efficacy of MET chemotherapy compared with transarterial
chemoembolization (TACE) in patients with child B class advanced hepatocellular carcinoma
(HCC). Methods Seventy-three patients with child B class advanced HCC were analyzed between
April, 2007 and August, 2013 according to two treatment groups: (i) MET chemotherapy group
(n=43, Epirubicin 35 mg/body surface area [BSA] every 4 weeks, and cisplatin 15 mg/BSA and
5-fluorouracil 50 mg/BSA weekly for 3 weeks) via an implantable port system with 1 week
break. (ii) TACE group (n=30, Adriamycin 20-50 mg) every 4 weeks. Primary endpoint was
overall survival (OS). Results The median survival times in the MET and TACE groups were 4.5 months and
3.1 months, respectively. The overall survival rate showed significantly better in the MET
treatment group than in the TACE group (P=0.039). When the factors affecting patient
OS were analyzed, MET chemotherapy (P=0.038, hazard ratio {HR} 0.538 [95% confidence
interval {CI} 0.299-0.967]) was independently associated with OS. Larger maximal tumor size,
extrahepatic metastasis and advanced stage also were significant factors for OS (P=0.009, HR
1.064 [95% CI 1.014-16.064]; P=0.014, HR 2.120 [95% CI 1.164-3.861]; P=0.019, HR 2.046 [95% CI
1.125-3.720], respectively). Conclusions MET chemotherapy showed survival benefit than TACE in patients with child
class B advanced HCC. Therefore, MET chemotherapy may be considered as a treatment
option for advanced HCC with poor liver function. (J Liver Cancer 2015;15:92-99)
