Background: Hepatocellular carcinoma (HCC) is one of the most common cancers in men and the third most common cancer in woman in Thailand. This retrospective study was designed to assess the prevalence, clinical manifestations, treatment outcomes and prognosis of HCC in the central region of Thailand. Materials and Methods: The authors retrospectively reviewed all HCC patients aged more than 15 years old in Thammasat university hospital (TUH) during the period from January 2007 to December 2012. Clinical information, biochemical tests and radiologic findings were collected from review of medical records. Results: There were 308 patients with HCC, which accounted for the prevalence of 5.19% of all cancers diagnosed in TUH during the study period. Of these, 125 (40.5%) had complete information retrievable from their medical records and met the inclusion criteria, 99 (79.2%) were males. The mean age was 57.4 years. A quarter of HCC patients in this study presented without any symptom before diagnosis. The common clinical presentations in the remaining patients were hepatomegaly 64/125 (51.2%), abdominal pain 56/125 (44.8%) and ascites 16/125 (20.8%). Cirrhosis was seen in almost all patients (92.8%). The most common causes of HCC in this study were chronic hepatitis B (49.6%) and C (19.2%). Based on Barcelona Clinic Liver Cancer staging, 75.4% presented at intermediate or late stage. Patients receiving curative therapy with either surgical treatment or radiofrequency ablation had significantly longer survival time after the HCC diagnosis than the palliative therapy group (11.0 months vs 4.0 months, p value= 0.004). The mean survival time after the HCC diagnosis was 10.5 months. Conclusions: The common causes of HCC in central region of Thailand were chronic hepatitis B and C. Surgical therapy or RFA seemed to provide better outcomes than other treatments but only in patients with early stage lesions. Most of the patients in this study presented with advanced diseases and had grave prognosis. Appropriate screening patients at risk for HCC might be an appropriate way to achieve early diagnosis and improve the treatment outcome.

Hepatocellular carcinoma (HCC) has been one of the most fatal malignant tumors worldwide and its associated morbidity and mortality remain of significant concern. Based on in-depth reviews of serological diagnosis of HCC, in addition to AFP, there are other biomarkers: Lens culinaris agglutinin-reactive AFP (AFP-L3), descarboxyprothrombin (DCP), tyrosine kinase with Ig and eprdermal growth factor (EGF) homology domains 2 (TIE2)-espressing monocytes (TEMs), glypican-3 (GPC3), Golgi protein 73 (GP73), interleukin-6 (IL-6), and squamous cell carcinoma antigen (SCCA) have been proposed as biomarkers for the early detection of HCC. The diagnosis of HCC is primarily based on noninvasive standard imaging methods, such as ultrasound (US), dynamic multiphasic multidetector-row CT (MDCT) and magnetic resonance imaging (MRI). Some experts advocate gadolinium diethyl-enetriamine pentaacetic acid (Gd-EOB-DTPA) MRI and contrast-enhanced US as the promising imaging madalities of choice. With regard to recent advancements in tissue markers, many cuting-edge technologies using genome-wide DNA microarrays, qRT-PCR, and proteomic and inmunostaining studies have been implemented in an attempt to identify markers for early diagnosis of HCC. Only less than half of HCC patients at initial diagnosis are at an early stage treatable with curative options: local ablation, surgical resection, or liver transplant. Transarterial chemoembolization (TACE) is considered the standard of care with palliation for intermediate stage HCC. Recent innovative procedures using drug-eluting-beads and radioembolization using Yttrium-90 may exhibit beneficial effects in HCC treatment. During the past few years, several molecular targeted agents have been evaluated in clinical trials in advanced HCC. Sorafenib is currently the only approved systemic treatment for HCC. It has been approved for the therapy of asymptomatic HCC patients with well-preserved liver function who are not candidates for potentially curative treatments, such as surgical resection or liver transplantation. In the USA, Europe and particularly Japan, hepatitis C virus (HCV) related HCC accounts for most liver cancer, as compared with Asia-Pacific regions, where hepatitis B virus (HBV) may play a more important role in HCC development. HBV vaccination, while a vaccine is not yet available against HCV, has been recognized as a best primary prevention method for HBV-related HCC, although in patients already infected with HBV or HCV, secondary prevention with antiviral therapy is still a reasonable strategy. In addition to HBV and HCV, attention should be paid to other relevant HCC risk factors, including nonalcoholic fatty liver disease due to obesity and diabetes, heavy alcohol consumption, and prolonged aflatoxin exposure. Interestingly, coffee and vitamin K2 have been proven to provide protective effects against HCC. Regarding tertiary prevention of HCC recurrence after surgical resection, addition of antiviral treatment has proven to be a rational strategy.

Hepatocellular carcinoma (HCC) is the sixth most common cancer and second leading cause of cancer-related death in the world. The aggressive but not always predictable pattern of HCC causes the limited treatment option and poorer outcome. Many researches had already proven the heterogeneity of HCC is one of the major challenges for treatment option and prognosis prediction. Molecular subtyping of HCC and selection of patient based on molecular profile can provide the optimization in the treatment and prognosis prediction. In this review, we have tried to summarize the molecular classification of HCC proposed by different valuable researches presented in the logistic way.

Objective: To investigate the changes of serum vascular endothelial growth factor (VEGF), soluble interleukin-2 receptor (SIL-2R) and hepatocyte growth factor (HGF) contents in patients with primary hepatocellular carcinoma (HCC) before and after percutaneous microwave coagulation therapy (PMCT) and determine their clinical significance. Materials and Methods: Fasting venous blood (3 mL) from 81 patients with primary HCC diagnosed by pathology was collected in the mornings 1 day before PMCT, and 1 day, 7 days and 1 month after PMCT, and then the serum was separated and stored in $-70^{\circ}C$. The contents of VEGF, SIL-2R and HGF were detected by enzyme linked immunosorbent assay (ELISA). Results: The serum VEGF, SIL-2R and HGF contents in 81 patients with primary HCC had obviously dynamic changes before and after PMCT. By comparison to 1 day after PMCT with pre-operation, there was no statistical significance regarding VEGF and SIL-2R contents (P>0.05), but HGF content showed significant difference (P<0.01). Compared with pre-operation, VEGF, SIL-2R and HGF contents 7 days and 1 month after PMCT all manifested significant differences (P<0.01). By comparison to 7 days with 1 month after PMCT, there was no statistical significance regarding the VEGF content (P>0.05), whereas SIL-2R and HGF contents showed significant change (P<0.01). Conclusions: The contents of serum VEGF, SIL-2R and HGF have obviously dynamic changes in primary HCC before and after PMCT, and their joint detection is expected to be an effective hematologic evaluation index of PMCT for primary HCC.

The incidence of hepatocellular carcinoma (HCC) is continuously increasing worldwide, with approximately 1 million new cases expected annually by 2025. Data from the Korean Central Cancer Registry in 2023 revealed that the survival rate of patients with HCC was only 40%, unlike patients with other major cancers with a 5-year survival rate of up to 80%, highlighting the need for improved outcomes. The prognosis of HCC significantly changed following research on immune checkpoint inhibitors (ICIs). Several studies have demonstrated that the overall survival of patients treated with first-line combination therapies, such as atezolizumab (anti-PD-L1) and bevacizumab (anti-VEGF) or durvalumab (anti-PD-L1) and tremelimumab (anti-CTLA-4), was higher than that of patients treated with sorafenib. Research to identify biomarkers that can predict ICI responses is ongoing, enabling the selection of suitable patients before drug initiation. Moreover, studies of the tumor microenvironment in HCC enhance our understanding of immune responses, helping us identify new therapeutic strategies. Additionally, clinical trials are being conducted for emerging immunotherapies beyond ICIs, such as adoptive cell therapy. Based on these ongoing scientific researches and the development of various therapeutic modalities, multiple options are being established for patients with HCC who do not respond well to first-line treatments. Consequently, treatment options and survival rates of patients with advanced HCC could be significantly enhanced in the future.

To unveil and delineate the elements applicable to the radiation protection of a femoral entry shield, calculate its mass attenuation coefficient, and demonstrate its dose reduction efficacy for interventional radiologist performing transarterial embolization (TAE) of ruptured hepatocellular carcinoma (rHCC). The lead equivalency of the shield was firstly validated. Electron microscopy was used to confirm the femoral entry shield being lead-free and to analyze the elemental content, with which the mass attenuation coefficient of the shield was calculated. An adult phantom, irradiated at the upper abdomen to simulate the TAE of rHCC, was used together with a dosimeter attached to the palm of a hand phantom. The dose rates at the hand phantom were measured, with the rHCC clinical protocol, without and with the femoral entry shield placed over the right femoral access site of the adult phantom. Without using the shield, the average hand dose rate was measured to be 0.325 µSv/sec. While using the shield, it was determined to be 0.110 µSv/sec. There was significant 66% dose reduction to the hand dose of IRs performing angiographic intervention with the femoral entry shield.

Hepatocellular carcinoma (HCC) is a biologically heterogeneous tumor characterized by varying degrees of aggressiveness. The current treatment strategy for HCC is predominantly determined by the overall tumor burden, and does not address the diverse prognoses of patients with HCC owing to its heterogeneity. Therefore, the prognostication of HCC using imaging data is crucial for optimizing patient management. Although some radiologic features have been demonstrated to be indicative of the biologic behavior of HCC, traditional radiologic methods for HCC prognostication are based on visually-assessed prognostic findings, and are limited by subjectivity and inter-observer variability. Consequently, artificial intelligence has emerged as a promising method for image-based prognostication of HCC. Unlike traditional radiologic image analysis, artificial intelligence based on radiomics or deep learning utilizes numerous image-derived quantitative features, potentially offering an objective, detailed, and comprehensive analysis of the tumor phenotypes. Artificial intelligence, particularly radiomics has displayed potential in a variety of applications, including the prediction of microvascular invasion, recurrence risk after locoregional treatment, and response to systemic therapy. This review highlights the potential value of artificial intelligence in the prognostication of HCC as well as its limitations and future prospects.

Hepatocellular carcinoma (HCC) is the most frequent type of malignant liver tumor and a high impact health problem worldwide. The prevalence of HCC is particularly high in many Asian and African countries. Some HCC patients have no symptoms prior to diagnosis and many of them therefore present at late stage and have a grave prognosis. The well-established causes of HCC are chronic hepatitis B virus (HBV) or chronic hepatitis C virus (HCV) infection or alcoholic cirrhosis and nonalcoholic steatohepatitis. The Barcelona Clinic Liver Cancer (BCLC) Staging System remains the most widely used for HCC management guidelines. To date, the treatments for HCC are still very challenging for physicians due to limited resources in many parts of the world, but many options of management have been proposed, including hepatic resection, liver transplantation, ablative therapy, chemoembolization, sorafnib and best supportive care. This review article describes the current evidence-based management of HCC with focus on early to advance stages that impact on patient overall survival.

Hepatocellular carcinoma (HCC) is the sixth most common cause of death worldwide and the main cause of primary liver cancer. The principle problem of HCC is the poor prognosis, since advanced HCC reportedly has a median survival of only 9 months. The standard therapies are sorafenib and regorafenib, but the outcomes remain unclear. We report a 60-year-old man with advanced HCC with right adrenal gland metastasis and portal vein tumor thrombosis, who showed a complete response to multiple applications of an interdisciplinary therapy.
