Background: Hepatitis B virus (HBV) is the leading cause of liver cancer, but the mechanisms by which HBV causes liver cancer are poorly understood and chemotherapeutic strategies to cure liver cancer are not available. A better understanding of how HBV requisitions cellular components in the liver will identify novel therapeutic targets for HBV associated hepatocellular carcinoma (HCC).
Main Body: The development of HCC involves deregulation in several cellular signalling pathways including Wnt/FZD/β-catenin, PI3K/Akt/mTOR, IRS1/IGF, and Ras/Raf/MAPK. HBV is known to dysregulate several hepatocyte pathways and cell cycle regulation resulting in HCC development. A number of these HBV induced changes are also mediated through the Wnt/FZD/β-catenin pathway. The lack of a suitable human liver model for the study of HBV has hampered research into understanding pathogenesis of HBV. Primary human hepatocytes provide one option; however, these cells are prone to losing their hepatic functionality and their ability to support HBV replication. Another approach involves induced-pluripotent stem (iPS) cell-derived hepatocytes. However, iPS technology relies on retroviruses or lentiviruses for effective gene delivery and pose the risk of activating a range of oncogenes. Liver organoids developed from patient-derived liver tissues provide a significant advance in HCC research. Liver organoids retain the characteristics of their original tissue, undergo unlimited expansion, can be differentiated into mature hepatocytes and are susceptible to natural infection with HBV.
Conclusion: By utilizing new ex vivo techniques like liver organoids it will become possible to develop improved and personalized therapeutic approaches that will improve HCC outcomes and potentially lead to a cure for HBV.

Background & Aims: This systematic literature review of qualitative findings aims to identify the perceived barriers and enablers for hepatocellular carcinoma (HCC) surveillance from patient and clinician perspectives.
Methods: A systematic search of databases using key term combinations with the following inclusion criteria: 1) qualitative and quantitative (survey) studies exploring barriers and enablers of HCC surveillance, and 2) qualitative and quantitative (survey) studies exploring barriers and enablers of enagagement in clinical care for patients with cirrhosis and/or viral hepatitis.
Results: The search returned 445 citations: 371 did not meet the study criteria and were excluded.

Rationale: Peliosis hepatis (PH) is a rare disease with few clinical reports and complex etiology. However, there have been no reports of hyperprolactinemia (HPRL) leading to PH at present. This paper, through case reports, expands the understanding of the etiology of PH and the pathological damage effect of prolactin (PRL).

Rationale: Peritoneal mucinous cystadenoma is rare in the clinic, lacks specific clinical manifestations, tumor markers, and imaging features, and is easily misdiagnosed and missed. Clinical practitioners should maintain a high level of vigilance. Here, we report a case of laparoscopic peritoneal mucinous cystadenoma stripping to improve our understanding of the disease.

Colorectal cancer is one of the most common malignant tumors in the world, and about 50% of its advanced patients will have liver metastasis. Preoperative assessment of the risk of liver metastasis in patients with colorectal cancer is of great significance for making individualized treatment plans. Traditional imaging examinations and tumor markers have some limitations in predicting the risk of liver metastasis.

Background: Few studies have explored the genetic changes and clinicopathological features of stage II/III gastric cancer (GC) patients with no tumor recurrence, early recurrence, or late recurrence after curative surgery.
Methods: In this study, 376 patients who underwent curative surgery for stage II/III GC were analyzed. The clinical and genetic features of patients with no recurrence, early recurrence (<2 years), and late recurrence (≥2 years) were compared.
