We performed a retrospective analysis of 46 patients with histologically confirmed hepatocellular carcinoma (HCC) who were treated with transarterial embolization (TAE) of the hepatic arteries. To induce permanent embolization, microspheres (Embosphere; 100 to 700 micron) and a mixture of ethiodized oil (Lipiodol Ultrafluide) with cyanoacrylate (Glubran) was injected. A total of 106 TAE procedures were performed. Cumulative survival rates were calculated. No patient died during embolization or within the first 24 hours. Severe procedure-related complications were observed in 2 patients. At the time of analysis, 38 of 46 patients were alive. The 180-, 360-, 520-, and 700-day cumulative survival rates for the total study population were 80.6%, 70.7%, 70.7%, and 47.1%, respectively, with a median survival of 666 days. TAE with the use of microspheres and Lipiodol and cyanoacrylate for unresectable HCC is a feasible treatment modality. Bland embolization with the use of microspheres can be used in patients for whom chemoembolization is not desired.

Despite the pivotal role of cytotoxic T lymphocytes (CTLs) in anti-tumor immunity, a substantial proportion of CTL-rich hepatocellular carcinoma (HCC) patients experience early relapse or immunotherapy resistance. However, spatial immune variations impacting the heterogeneous clinical outcomes of CTL-rich HCCs remain poorly understood. Here, we compared the single-cell and spatial landscapes of 20 CTL-rich HCCs with distinct prognoses using multiplexed in situ staining and validated the prognostic value of myeloid spatial patterns in a cohort of 386 patients.

Supervillin (SVIL), the biggest member of the villin/gelsolin superfamily, has recently been reported to promote the metastasis of hepatocellular carcinoma by stimulating epithelial-mesenchymal transition (EMT). However, little is known about the roles of SVIL in the migration of colorectal cancer cells. Here, we investigated the effects of SVIL on the migration of cisplatin-resistant colorectal cancer cells.

Objectives: We aimed to study sarcopenia for its significance in predicting the effect of hepatic artery intervention (HAI) plus lenvatinib on hepatitis B-related hepatocellular carcinoma (HCC) complicated with diabetes mellitus (DM).
Materials And Methods: Hepatitis B-related HCC patients complicated with DM (n = 102) visiting during January 2021 and December 2023 were retrospectively selected. Computed tomography was performed to detect the third lumbar vertebra for its muscle cross-sectional area.

Hepatocellular carcinoma (HCC) is one of the leading causes of cancer-related death worldwide. However, the molecular mechanism underlying the occurrence and development of HCC remains unclear. We are interested in the function of m6A methylation enzyme WTAP in the occurrence and development of HCC.

Given the crucial role of mitochondria in the prognosis and treatment of hepatocellular carcinoma (HCC), we aim to develop two independent mitochondrial scoring systems to separately predict patient prognosis and the likelihood of transarterial chemoembolization non-response (TACE NR). Mitochondria-related candidate genes were selected and analyzed using univariate Cox and LASSO Cox regression analyses to create a risk prognosis score (RPS). Univariate and LASSO logistic regression analyses were used to establish the risk diagnosis score (RDS).
