Backgrounds/Aims This study explored the initial institutional experience of using gold fiducial markers for stereotactic body radiotherapy (SBRT) in treating malignant hepatic tumors using real-time ultrasound-computed tomography (CT)/magnetic resonance (MR) imaging fusion-guided percutaneous placement.
Methods From May 2021 to August 2023, 19 patients with 25 liver tumors that were invisible on pre-contrast CT received fiducial markers following these guidelines. Postprocedural scans were used to confirm their placement. We assessed technical and clinical success rates and monitored complications. The implantation of fiducial markers facilitating adequate treatment prior to SBRT, which was achieved in 96% of the cases (24 of 25 tumors), was considered technical success. Clinical success was the successful completion of SBRT without evidence of marker displacement and was achieved in 88% of cases (22 of 25 tumors). Complications included one major subcapsular hematoma and marker migration into the right atrium in two cases, which prevented SBRT.
Results Among the treated tumors, 20 of 24 (83.3%) showed a complete response, three of 24 (12.5%) remained stable, and one of 24 (4.2%) progressed during an average 11.7-month follow-up (range, 2-32 months).
Conclusions This study confirms that percutaneous gold fiducial marker placement using real-time CT/MR guidance is effective and safe for SBRT in hepatic tumors, but warns of marker migration risks, especially near the hepatic veins and in subcapsular locations. Using fewer markers than traditionally recommended-typically two per patient, the outcomes were still satisfactory, particularly given the increased risk of migration when markers were placed near major hepatic veins.
This review examines the transformative role of external beam radiotherapy (EBRT) in managing hepatocellular carcinoma (HCC), spotlighting the progression from traditional EBRT techniques to advanced modalities like intensity-modulated radiotherapy (RT), stereotactic body RT (SBRT), and innovative particle therapy, including proton beam therapy and carbon ion RT. These advancements have significantly improved the precision and efficacy of RT, marking a paradigm shift in the multimodal management of HCC, particularly in addressing complex cases and enhancing local tumor control. The review underscores the synergistic potential of integrating RT with other treatments like transarterial chemoembolization, systemic therapies such as sorafenib, and emerging immunotherapies, illustrating enhanced survival and disease control outcomes. The efficacy of RT is addressed for challenging conditions, including advanced HCC with macrovascular invasion, and RT modalities, like SBRT, are compared against traditional treatments like radiofrequency ablation for early-stage HCC. Additionally, the review accentuates the encouraging outcomes of particle therapy in enhancing local control and survival rates, minimizing treatment-related toxicity, and advocating for continued research and clinical trials. In conclusion, the integration of RT into multimodal HCC treatment strategies, coupled with the emergence of particle therapy, is crucial for advancing oncologic management, emphasizing the need for relentless innovation and personalized treatment approaches.
Background/Aim The aim of this study was to compare the therapeutic efficacy of ablation and surgery in solitary hepatocellular carcinoma (HCC) measuring ≤5 cm with a large HCC cohort database.
Methods The study included consecutive 2,067 patients with solitary HCC who were treated with either ablation (n=1,248) or surgery (n=819). Th e patients were divided into three groups based on the tumor size and compared the outcomes of the two therapies using propensity score matching.
Results No significant difference in recurrence-free survival (RFS) or overall survival (OS) was found between surgery and ablation groups for tumors measuring ≤2 cm or >2 cm but ≤3 cm. For tumors measuring >3 cm but ≤5 cm, RFS was significantly better with surgery than with ablation (3.6 and 2.0 years, respectively, P=0.0297). However, no significant difference in OS was found between surgery and ablation in this group (6.7 and 6.0 years, respectively, P=0.668).
Conclusion The study suggests that surgery and ablation can be equally used as a treatment for solitary HCC no more than 3 cm in diameter. For HCCs measuring 3-5 cm, the OS was not different between therapies; thus, ablation and less invasive therapy can be considered a treatment option; however, special caution should be taken to prevent recurrence.

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 Since the introduction of laparoscopy for liver resection in the 1990s, the performance of laparoscopic liver resection (LLR) has been steadily increasing. However, there is currently no data on the extent to which laparoscopy is used for liver resection. Herein, we investigated the extent to which laparoscopy is performed in liver resection and sought to determine whether surgeons prefer laparoscopy or laparotomy in the posterosuperior (PS) segment.
Methods For this retrospective observational study, we enrolled patients who had undergone liver resection at the Samsung Medical Center between January 2020 and December 2021. The proportion of LLR in liver resection was calculated, and the incidence and causes of open conversion were investigated.
Results A total of 1,095 patients were included in this study. LLR accounted for 79% of the total liver resections. The percentage of previous hepatectomy (16.2% vs. 5.9%, P<0.001) and maximum tumor size (median 4.8 vs. 2.8, P<0.001) were higher in the open liver resection (OLR) group. Subgroup analysis revealed that tumor size (median 6.3 vs. 2.9, P<0.001) and surgical extent (P<0.001) in the OLR group were larger than those in the LLR group. The most common cause of open conversion (OC) was adhesion (57%), and all OC patients had tumors in the PS.
Conclusions We investigated the recent preference of practical surgeons in liver resection, and found that surgeons preferred OLR to LLR when treating a large tumor located in the PS.

Fibrolamellar hepatocellular carcinoma (FLHCC) is a rare malignant hepatic cancer with characteristics that differ from those of typical hepatocellular carcinoma (HCC). Unlike conventional HCC, FLHCC is common in young patients without any underlying liver disease and is known to be associated with a unique gene mutation. This cancer type is rare in Asia, with only a few cases being reported in Korea. We report a case of FLHCC in a young woman that successfully underwent surgical resection. The efficacy of alternative treatments, such as transarterial chemoembolization or systemic chemotherapies, has not yet been established. To conclude, early diagnosis and appropriate surgical resection are important for the treatment of FLHCC.

Hepatocellular adenoma is a benign tumor of the liver occurring predominantly in young women taking oral contraceptives. The malignant transformation of hepatocellular adenoma into hepatocellular carcinoma has rarely been reported. Herein, we report the case of an elderly male patient with hepatocellular carcinoma that developed from hepatocellular adenoma. The patient’s high risk for surgery and conflicting biopsy and imaging results made it difficult to determine the treatment direction. Eventually, the mass was completely removed by laparoscopic left hemi-hepatectomy without complications.

In the Barcelona Clinic Liver Cancer staging system, intermediate stage hepatocellular carcinoma (HCC) is defined as large multinodular tumors without vascular invasion or extrahepatic spread in an asymptomatic patient with good performance status. Intermediate stage HCC includes various subgroups and it is characterized by extensive heterogeneity. Current guidelines recommend transarterial chemoembolization (TACE) as the standard treatment modality for patients with intermediate stage HCC. Although TACE provides improved survival benefits compared with supportive care for patients with intermediate stage HCC, all of them are not good candidates for TACE. TACE refractoriness is another obstacle to effective treatment of patients with intermediate stage HCC. Given that many studies recently reported improved survival in patients treated with hepatic resection over TACE, we reviewed the survival outcomes of TACE and hepatic resection as a treatment strategy of intermediate stage HCC.
Although surgical resection is a curative treatment option for solitary hepatocellular carcinoma, high recurrence rate contributes to dismal long-term prognosis after curative resection. Early recurrence within 2 years after surgery is associated with intrahepatic metastasis of primary tumor. Liver regeneration after hepatic resection can accelerate tumorigenesis in remnant liver. Treatment strategies for intrahepatic recurrence after curative resection include salvage transplantation, repeated resection, local ablation, and transarterial chemoembolization (TACE).
Here, we report a 51-year-old male who was presented with a single large tumor located at segment 4. The patient was initially treated with surgical resection, but intrahepatic recurrence occurred only 4 months after surgery. He achieved complete remission with repeated TACE and has survived without recurrence for 4 years so far.
Hepatocellular carcinoma (HCC) with portal vein invasion has a poor prognosis. Treatments
such as transarterial chemoembolization (TACE), radiation therapy (RT), sorafenib are done
as a first line treatment. But in case of incomplete response to first line treatment, there’s
no established guideline about salvage treatment. We present a 47 year-old male who was
diagnosed as HCC with portal vein invasion. He was treated with RT and repeated TACE,
but remnant viable tumor was observed. Surgical resection was performed as a salvage
treatment, and HCC was completely removed. He has been followed up over 3 years, but there
was no recurrence.
Brain metastasis is a rare condition of extraheptaic metastases in hepatocellular carcinoma
(HCC). Patients with hepatocellular carcinoma and brain metastasis have rapidly worsened
neurologic signs and symptoms, therefore it is regarded to oncologic emergency. Current
recommended treatments for brain metastasis are surgical resection or gamma-knife surgery
with/without whole brain radiation therapy (RT). However, patients with brain metastasis
have a very poor prognosis after adequate treatment. Here, we report a 62-year-old man with
HCC and brain metastasis who had long term survival after surgical resection and whole brain
RT. (J Liver Cancer 2016;16:38-41)
Although surgical resection can provide best treatment outcome with curative intent,
patients with relatively early stage of hepatocellular carcinoma (HCC) can get benefit of this
treatment. Barcelona Clinic Liver Cancer (BCLC) staging system limits surgical resection to
patients with single HCC with well-preserved liver function, which is often challenged in real
practice, especially from Asian countries. During last two decades, surgical outcomes have
made remarkable progress approaching zero mortality in many reports. In this review, areas
that surgical indications can be expanded beyond BCLC staging system will be discussed,
especially in Asian population. (Journal of Liver Cancer 2015;15:1-3)
According to updated BCLC guideline, radiofrequency ablation (RFA) is now accepted as a standard treatment for
hepatocellular carcinomas (HCCs) smaller than 2 cm in diameter in patients who are not considered for liver transplantation. This
is because of acceptable local tumor control and survival gain of RFA for small HCCs compared to those of surgical resection.
However, for RFA to be a standard treatment of small HCCs, not only expertise of operator but also optimal guiding and ablation
techniques such as fusion imaging, contrast-enhanced ultrasonography, artificial ascites, and switching monopolar RFA using
multiple electrodes are necessary. Since RFA and surgical resection are equally effective for very early stage HCC; tumor
location (i.e., central vs. peripheral location, proximity to central bile duct) and individual condition of patients should be taken
into consideration for choosing appropriate treatment. Microwave ablation, which is an emerging thermal ablation technique, is
expected to play a key role in the local ablation therapy of small HCCs in the near future. However, more evidence and data is
required to verify the efficacy of microwave ablation for the treatment of small HCCs.
Cure by single modality for advanced hepatocellular carcinoma (HCC) is difficult. Therefore, multidisciplinary approaches are
needed to get a better outcome for advanced HCC. In this paper, we report a case of advanced HCC treated with curative surgical
resection after downstaging by hepatic arterial infusion chemotherapy (HAIC). A 50-year-old male patient had a maximum 16.0
cm sized HCC in the right lobe. He achieved a partial response after 2 cycles of HAIC with 5-FU (750 mg/m2) and cisplatin (25
mg/m2). After completion of 6 cycles, he received a curative right hepatectomy and the histopathology revealed 95% of tumor
necrosis. He is under follow-up without recurrence at 14 months of surgery. This case suggests that surgery after downstaging by
HAIC may provide good clinical outcome in advanced HCC.
Surgical resection for hepatocellular carcinoma (HCC) is one of the managements, showing improved long term survival.
Nowadays, it is being accepted as the main curative treatment. However, the biggest problem we used to face is that surgery
cannot be applied at the point of presentation in many patients due to advanced stage. Here we present a case of 54 years old
female, who had transarterial chemoembolization (TACE) and sorafenib due to advanced stage of HCC, and later underwent
curative surgery due to remarkable response. She had a CT scan of abdomen, which showed multiple huge masses. HCC was
confirmed by ultrasonography-guided liver biopsy. TACE was performed once. After TACE, the size of masses increased.
Therefore, sorafenib was administered and then continued for 9 months. As partial response was obtained at that time, surgical
resection was successfully done. In the pathological report of removed tumor, we could confirm total necrosis of tumor. Now, its
been 6 months and she is followed up without any recurrence.
