Transarterial radioembolization (TARE) is a recommended locoregional strategy for intermediate hepatocellular carcinoma (HCC), whereas, the effect is insufficient to reverse the immunosuppression tumor microenvironment, and the overall benefits for patients remain to be improved. In this study, a multifunctional microsphere (MS) I-ICT/R848-MS is developed to propose an approach combined with TARE, icaritin (ICT) and immune modulator resiquimod (R848). ICT and iodine-131 (I) radiation can induce immunogenic cell death, which, in combination with R848, will boost dendritic cell (DC) maturation.

Background: In radioembolization therapy for hepatic malignancies, the accurate estimation of lung shunt fraction (LSF) is crucial to minimize the risk of radiation-induced pneumonitis and fibrosis due to hepatopulmonary shunting of yttrium-90 (90Y)-microspheres. This study aimed to compare the accuracy and precision of LSF estimation using technetium-99m macroaggregated albumin single photon emission computed tomography ([99mTc]Tc-MAA SPECT) LSF, [99mTc]Tc-MAA planar LSF, and 90Y PET LSF in patients undergoing 90Y-radioembolization.
Material And Methods: A retrospective study was conducted involving 15 patients diagnosed with hepatocellular carcinoma (HCC) or liver metastases and planned to undergo transarterial radioembolization with 90Y SirSpheres after multidisplinary team discussion.
Transarterial Chemoembolization Plus Camrelizumab and Rivoceranib versus Camrelizumab and Rivoceranib Alone for BCLC Stage C Hepatocellular Carcinoma.

Purpose: Camrelizumab and rivoceranib together provide a new first-line treatment approach for unresectable hepatocellular carcinoma (HCC). Meanwhile, transarterial chemoembolization (TACE) is an effective method for the local control of the HCC. The study compared the clinical benefit and safety between TACE with camrelizumab-rivoceranib and camrelizumab-rivoceranib alone for Barcelona Clinic Liver Cancer (BCLC)-C HCC patients.

This article explores the integration of Eastern and Western perspectives on the use of dexamethasone and N-acetylcysteine as premedications in transarterial chemoembolization for hepatocellular carcinoma (HCC). By examining key concerns raised by Western researchers, particularly regarding the different etiologies of liver cirrhosis, and contrasting them with robust clinical data from Asia, this article highlights the necessity for region-specific research and proposes future directions for global HCC management.

In the clinic, Lipiodol chemotherapeutic emulsions remain a main choice for patients diagnosed with hepatocellular carcinoma (HCC) via the mini-invasive transarterial chemoembolization (TACE) therapy. However, the poor stability of conventional Lipiodol chemotherapeutic emulsions would result in the fast drug diffusion and incomplete embolization, inducing systemic toxicity and impairing the efficacy of TACE therapy. Therefore, it is of great importance to construct alternative formulations based on commercial Lipiodol to achieve the improved efficacy and safety of HCC treatment.
