Alpha-fetoprotein (AFP) is a classic biomarker for hepatocellular carcinoma (HCC). AFP-positive HCC (AFP HCC) has been intensively investigated; however, the genomic, transcriptomic and microenvironmental characteristics of AFP-negative HCC (AFP HCC) remain to be deciphered. Here we show that tumors display mild differences in genetic alterations between AFP HCC and AFP HCC patients, while AFP HCC exhibits hyperactive arachidonic acid metabolism. Furthermore, the transcription activity of androgen receptor (AR) is significantly increased in AFP HCC and plays a positive regulatory role in arachidonic acid metabolism and its metabolite 11,12-epoxyeicosatrienoic acid (11,12-EET). The tumor-derived 11,12-EET exhibits high affinity for EGFR that promotes the migration and tube formation of endothelial cells in vitro. Combination of lenvatinib and bicalutamide (an AR antagonist) enhances the therapeutic efficacy for AFP HCC. Overall, we uncover the AR-mediated hyperactive arachidonic acid metabolism in AFP HCC, and reveal AR-11,12-EET-EGFR axis-induced angiogenesis, providing a promising strategy of combined AR antagonist with lenvatinib for AFP HCC treatment.

Hematogenous metastases of hepatocellular carcinoma (HCC) to the small intestine are rare. In most cases, hematogenous metastasis is symptomatic, including perforation or bleeding, and the prognosis is poor. A 63-year-old man had lower right abdominal pain, and small intestinal obstruction due to chronic inflammation of the foreign body was suspected on computed tomography.

Background: Hepatocellular carcinoma (HCC) patients who underwent transarterial chemoembolization (TACE) have heterogeneous clinical outcomes. Accurate prognosis prediction and risk stratification are crucial for individualized treatment. We sought to develop a novel prognostic model for overall survival (OS) that incorporated contemporary clinical and laboratory factors for estimating individual prognosis.

Background: Patients with hepatocellular carcinoma (HCC) with major vascular invasion (MaVI) have a poor prognosis. In this study, we aimed to develop a nomogram model for predicting the prognosis of HCC with MaVI.
Methods: Data of 2211 patients were extracted from the Surveillance, Epidemiology, and End Results (SEER) database on September 25, 2024.

The elevation of serum alpha-fetoprotein (AFP) is frequently observed in patients with chronic hepatitis C (CHC). In most cases, the level decreased after antiviral treatment. This study investigated the relationship between post-treatment AFP normalization and the risk of hepatocellular carcinoma (HCC) in CHC patients without baseline HCC.

To evaluate the value of a multiparametric MRI-based nomogram on predicting response to transcatheter arterial chemoembolization (TACE) in virus-associated hepatocellular carcinoma (HCC) patients; METHODS: This study enrolled 235 and 51 patients from Center 1 and 2, respectively. All patients underwent baseline MRI scans before treatment. The least absolute shrinkage and selection operator (LASSO) regression method was used to screen radiomics features from intra- and peri-tumor areas to establish the radiomics signatures (RS).
