Globally, one in six deaths is reported due to cancer suggesting the critical need for development of advanced treatment regimens. In this study, solid lipid nanoparticles (SLN) were prepared and appended with polyethylene glycol (PEGylated) galactose and a multikinase inhibitor sorafenib (SRFB) was used as chemotherapeutic drug, for treating hepatocellular carcinoma (HCC). The nanoparticles were evaluated for in-vitro and in-vivo performances to showcase the targeting efficiency and therapeutic benefits of the sorafenib loaded ligand conjugated nanoparticles (GAL-SSLN). When compared with SRFB or Sorafenib loaded SLN, GAL-SSLN showed superior cytotoxicity and apoptosis in HepG2 (human hepatocellular carcinoma cells). In addition, in-vivo pharmacokinetics and real time biodistribution studies in BALB/c mice showed that the surface conjugation of nanoparticles with galactose resulted in better pharmacokinetic performance and targeted delivery of the nanoparticles to liver. Results indicated that GAL-SSLN showed promising attributes in terms of targeting sorafenib to liver and therapeutic efficacy.

Cancer, a complicated disease characterized by aberrant cellular metabolism, has emerged as a formidable global health challenge. Since the discovery of abnormal aldolase A (ALDOA) expression in liver cancer for the first time, its overexpression has been identified in numerous cancers, including colorectal cancer (CRC), breast cancer (BC), cervical adenocarcinoma (CAC), non-small cell lung cancer (NSCLC), gastric cancer (GC), hepatocellular carcinoma (HCC), pancreatic cancer adenocarcinoma (PDAC), and clear cell renal cell carcinoma (ccRCC). Moreover, ALDOA overexpression promotes cancer cell proliferation, invasion, migration, and drug resistance, and is closely related to poor prognosis of patients with cancer.

Portal vein tumor thrombus (PVTT) is a poor prognostic factor for hepatocellular carcinoma (HCC) patients, highlighting the need for an oral drug delivery system that combines convenience, simplicity, biosafety, and improved patient compliance. Leveraging the unique anatomy of the portal vein and insights from single-cell RNA sequencing of the PVTT tumor microenvironment, we developed oral pellets using CaCO@PDA nanoparticles (NPs) encapsulating both doxorubicin hydrochloride and low molecular weight heparin. These NPs target the tumor thrombus microenvironment, aiming to break down the thrombus barrier and turn the challenge of portal vein blockage into an advantage by enhancing drug delivery efficiency through oral administration.

Hepatitis D virus (HDV) significantly influences the progression of liver diseases. Through clinical observations and database analyses, it has been established that patients coinfected with HDV and hepatitis B virus (HBV) experience accelerated progression toward cirrhosis, hepatocellular carcinoma (HCC), and liver failure compared to those infected solely with HBV. A higher viral load correlates with increased replicative activity, enhanced infectivity, and more severe disease manifestations.

Background/purpose: Dysbiosis of oral microbiota has been reported in late stage of chronic hepatitis B (CHB) infection with cirrhosis. CHB is characterized by the constant virus-induced liver injury which may lead to liver cirrhosis and hepatocellular carcinoma (HCC). However, some patients show normal liver function without antiviral treatment, associating with favourable prognosis.

Objective: This study aimed to investigate how dynamic contrast-enhanced CT imaging signs correlate with the differentiation grade and microvascular invasion (MVI) of hepatocellular carcinoma (HCC), and to assess their predictive value for MVI when combined with clinical characteristics.
Methods: We conducted a retrospective analysis of clinical data from 232 patients diagnosed with HCC at our hospital between 2021 and 2022. All patients underwent preoperative enhanced CT scans, laboratory tests, and postoperative pathological examinations.
