Purpose: To determine the frequencies of various echogenicity patterns in 153 consecutive unifocal hepatocellular carcinomas (HCCs) <2 cm detected in cirrhotic livers and to identify their relationships with clinical, laboratory, and microscopic features.
Patients And Methods: The tumors were classified as hypoechoic, hyperechoic, isoechoic, or nodule-in-nodule. Correlation was evaluated between hypoechoic and hyperechoic patterns and the following variables: age, gender, serum alphafetoprotein (AFP), tumor size, ultrasound features of liver parenchyma, cirrhosis etiology, and cyto/histological tumor grading.
Results: One hundred and seventeen tumors (76.4%) were hypoechoic, 26 (17.0%) were hyperechoic, 5 (3.3%) were isoechoic, and 5 (3.3%) had nodule-in-nodule patterns. The hyperechoic pattern was more common in patients under 69 years (25.0% vs. 11.3% in those under 69 years or older, P=0.033). Patients with a hyperechoic pattern displayed a trend towards lower AFP levels and higher prevalence of hepatitis C-related cirrhosis. The prevalence of well-differentiated tumors was identical (56.6% and 56.5%) in the hypoechoic and hyperechoic subgroups. AFP was higher than 400 ng/ml in only 11/153 cases (7.2%).
Conclusions: The hyperechoic pattern of HCC is by no means uncommon, particularly in patients under 70. Hyperechogenicity is not related to an increased frequency of well-differentiated tumors. AFP shows limited value as a confirmatory test of small HCC.

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.

Specific tumor-targeted gene delivery remains an unsolved therapeutic issue due to aberrant vascularization in tumor microenvironment (TME). Some bacteria exhibit spontaneous chemotaxis toward the anaerobic and immune-suppressive TME, which makes them ideal natural vehicles for cancer gene therapy. Here, we conjugated ZIF-8 metal-organic frameworks encapsulating eukaryotic murine interleukin 2 () expression plasmid onto the surface of VNP20009, an attenuated strain with well-documented anti-cancer activity, and constructed a TME-targeted delivery system named /ZIF-8@.

Hepatocellular carcinoma (HCC) with coexisting portal vein tumor thrombus (PVTT) is associated with poor patient outcomes. The efficacy and safety of neoadjuvant therapy in patients with HCC with PVTT remain a subject of debate. In the present study, a comprehensive search of electronic databases, including PubMed, Web of Science, Embase and the Cochrane Library, was conducted to identify studies evaluating the outcomes of neoadjuvant therapy in patients with HCC and PVTT.
