Hepatocellular carcinoma with portal venous invasion has a poor prognosis. We report a case treated successfully by intra-arterial 5-fluorouracil with systemic pegylated-interferon-alpha-2b instead of conventional interferon-alpha. A 66-year-old man was admitted to our hospital, and diagnosed with hepatocellular carcinoma with portal venous invasion. Following informed consent, he was treated with eight week cycles of combination chemotherapy using intra-arterial 5-fluorouracil (500 mg/body/day i.a., days 1-5, 8-12 continuously) and pegylated-interferon-alpha-2b (100 microg body s.c., days 1, 8). No significant side effects were observed during his therapy. After 4 cycles, computed tomography scan revealed a partial response of tumor reduction. This is the first report of advanced hepatocellular carcinoma effectively treated using subcutaneous pegylated-interferon-alpha-2b with intra-arterial 5-fluorouracil. While the conventional therapy of interferon-alpha with 5-fluorouracil has significant side effects, no significant side effects were observed in our case. The use of subcutaneous pegylated-interferon-alpha-2b combined with intraarterial 5-fluorouracil, may improve patients' quality of life.

Purpose: To analyze survival and its predictors among patients with hepatocellular carcinoma (HCC) receiving transarterial chemoembolization (TACE) in Ethiopia.
Materials And Methods: We conducted a retrospective cohort study among patients who received TACE for HCC at MCM Hospital from December 1, 2016, to December 31, 2022. Data were extracted from patients' medical records, and vital status was ascertained from the patients' charts or by phone call to the next of kin.

Aflatoxin B1 (AFB1) is a class 1 carcinogen and mycotoxin known to contribute to the development of hepatocellular carcinoma (HCC), growth impairment, altered immune system modulation, and malnutrition. AFB1 is synthesized by Aspergillus flavus and is known to widely contaminate foodstuffs, particularly maize, wheat, and groundnuts. The mechanism in which AFB1 causes genetic mutations has been well studied, however its metabolomic effects remained largely unknown.

Hepatobiliary (HB) contrast agents are increasingly valuable diagnostic tools in MRI, offering a wider range of applications as their clinical use expands. Normal hepatocytes take up HB contrast agents, which are subsequently excreted in bile. This property creates a distinct HB phase providing valuable insights into liver function and biliary anatomy.

Background: Immune checkpoint inhibitors (ICIs) combined with anti-vascular endothelial growth factor (VEGF) have been the standard first-line treatment of hepatocellular carcinoma (HCC). However, the efficacy of this combination in post-line treatment is still unknown. This study aimed to evaluate the efficacy and safety of the combination of anti-PD-L1 envafolimab and novel humanized anti-VEGF suvemcitug as second-line treatment for patients with HCC.

Arsenic trioxide (ATO), the active ingredient in Chinese arsenic, effectively inhibits hepatocellular carcinoma (HCC) cell growth, but its clinical application is limited by the lack of a targeted delivery system. Phosphatidylinositol proteoglycan 3 (GPC3) is specifically expressed in HCC, and CPP44 is a cell-penetrating peptide that targets HCC cells. Here, we developed a liposome incorporating ATO with dual surface modifications of anti-GPC3 antibody and CPP44.
