AI Article Synopsis
- An estimated 2.4 million Americans, including veterans, are chronically infected with hepatitis C (HCV) and it's linked to both liver cancer and potentially other extrahepatic cancers (EHCs).
- The study reviewed data from 1541 patients at a VA clinic to examine the impact of liver fibrosis and chronic HCV infection on the risk of developing EHCs.
- Findings indicated that older age and higher liver stiffness measurements are significantly associated with an increased risk of EHCs, particularly prostate, head and neck, lung, and hematologic cancers.
Article Abstract
Background And Aims: An estimated 2.4 million Americans, including more than 150,000 veterans, are chronically infected with hepatitis C virus (HCV). HCV is estimated to cause roughly 25% of all hepatocellular carcinoma. Although its mechanism is unknown, developing evidence suggests that chronic HCV infection is also associated with the development of extrahepatic cancers (EHCs). This paper aims to assess the relationship of hepatic fibrosis and chronic HCV with the risk of developing EHC.
Methods: We conducted a single-center retrospective chart review of 1541 patients linked to the hepatitis clinic at the Veterans Affairs (VA) Maryland Health Care System who underwent transient elastography for evaluation and management of liver disease from 2014 to 2018. Liver fibrosis was measured using ultrasound and transient elastography. Extrahepatic cancer and site was identified by a retrospective chart review.
Results: In adjusted analysis of EHCs, advanced age (OR: 1.97, 95% CI: 1.30-3.04), and higher measured stiffness (OR 2.19, 95% CI: 1.32-3.64) were associated with an increased likelihood of developing EHC, controlling for HBV infection, HCV exposure, heavy alcohol use, and body mass index.
Conclusions: We observed a significant association between increasing age and increasing levels of liver fibrosis with increased risk of EHC, notably prostate, head and neck squamous cell, lung, and hematologic cancers.

Congenital extrahepatic portosystemic shunt, also known as Abernethy malformation, is a rare anatomic vascular malformation. Patients with Abernethy malformation may present with abdominal pain, abnormal liver function tests, hepatopulmonary syndrome, pulmonary hypertension, and/or portosystemic encephalopathy. Accurate identification of the shunt and portal vein and effective management of complications is vital in these patients.

Background: AT-rich interaction domain 4B (ARID4B) is a transcriptional activator that regulates the phosphatidylinositol 3-kinase (PI3K)/AKT pathway in prostate cancer. However, the role of ARID4B in hepatocellular carcinoma (HCC) has remained unclear.
Methods: This study included 162 patients who had undergone primary hepatic resection for HCC between 2008 and 2019.

Given the increasing trend of cholecystectomy, it is imperative to reassess surgical and surveillance strategies in consideration of the potential long-term risks for digestive tract cancers. The objective of this study was to assess the risk of gastrointestinal (GI) and hepato-biliary-pancreatic (HBP) cancer incidence after cholecystectomy. The data for this cohort study was obtained from the National Health Insurance Service database in Korea.

Background/aim: Liver metastasis (LM), pre-dominant in pancreatic cancer, is associated with a dismal 5-year survival rate. Reports on the presence of fatty liver and liver fibrosis in LM are conflicting. Although liver biopsy is the standard diagnostic method for fibrosis, alternative, less invasive scoring models have been explored.

Background/aim: Predictors of recurrence following resection of hepatocellular carcinoma (HCC) are not fully established. This study investigated potential risk factors and prognostic scores for this situation.
Patients And Methods: In 297 patients undergoing resection of HCC between 2000 and 2021, risk scores and potential additional risk factors for intrahepatic and extrahepatic recurrence were assessed.
