Hepatitis C virus (HCV) infection is associated with a myriad of extrahepatic manifestations (EHM), as well as the production of autoantibodies, including rheumatoid factor (RF). This study aims to elucidate whether serum levels of RF change before and after HCV eradication, and whether these changes differ according to the type of therapy used. This is a retrospective cohort study of adults with chronic HCV infection treated with interferon-free or interferon-based regimens.

Background And Aims: Metachronous recurrence frequently develops in patients with superficial esophageal squamous cell carcinomas (ESCCs) after curative endoscopic submucosal dissection (ESD), especially in those with multiple (>10) small Lugol-voiding lesions (LVLs) over the endoscopic background mucosa (ie, speckled pattern). We conducted a randomized controlled trial to investigate whether endoscopic radiofrequency ablation (RFA) for endoscopic background mucosal resurfacing (EBMR) can decrease the rate of metachronous neoplasia.

Methods: Patients who received curative ESD and whose Lugol staining showed a speckled pattern over the background mucosa were randomly assigned in a 1:1 ratio to receive either RFA (EBMR group) or endoscopic surveillance alone (control group).

Background: Vonoprazan, a potassium-competitive acid blocker, has demonstrated greater potency and a longer duration of acid suppression when compared to the proton pump inhibitors. However, data regarding the comparison between vonoprazan-based triple therapy with standard treatment for first-line Helicobacter pylori treatment are limited. This study aimed to compare the efficacy between 7-day vonoprazan-based triple therapy with high-dose amoxicillin (VAC-7) and 14-day extended sequential therapy (S-14).

Background And Aims: Endoscopic radiofrequency ablation (RFA) has shown good efficacy and safety in eradicating flat-type early esophageal squamous cell neoplasia (ESCN). However, post-RFA stricture is still a major concern, especially when treating ultralong-segment ESCNs. The aim of this study was to investigate the efficacy and safety of oral prednisolone to prevent post-RFA stricture.

Background: Patients with head and neck squamous cell carcinoma (HNSCC) frequently develop synchronous esophageal cancer (ESCC), but there is a lack of clinical predictors. The neutrophil to lymphocyte (NLR), platelet to lymphocyte (PLR), and lymphocyte to monocyte ratios (LMRs), reflect the balance between pro-cancer inflammation and anti-cancer immune responses, but their role in HNSCC and synchronous cancer remain uncertain.

Method: The study consecutively enrolled a total of 717 patients with newly diagnosed HNSCC who received pre-treatment esophageal endoscopic screening.

Kirsten rat sarcoma virus (KRAS) signaling drives pancreatic ductal adenocarcinoma (PDAC) malignancy, which is an unmet clinical need. Here, we identify a disintegrin and metalloproteinase domain (ADAM)9 as a modulator of PDAC progression via stabilization of wild-type and mutant KRAS proteins. Mechanistically, ADAM9 loss increases the interaction of KRAS with plasminogen activator inhibitor 1 (PAI-1), which functions as a selective autophagy receptor in conjunction with light chain 3 (LC3), triggering lysosomal degradation of KRAS.

Article Synopsis
  • The study evaluated the global prevalence of Helicobacter pylori (H pylori) infection in adults and children/adolescents, linking it to gastric cancer rates.
  • After reviewing nearly 17,000 articles, researchers found that H pylori infection prevalence dropped from 52.6% to 43.9% in adults but remained at 35.1% in children and adolescents from 2015 to 2022.
  • The decline in H pylori in adults was significant in certain regions, while the relationship between H pylori prevalence and decreasing gastric cancer incidence prompts the need for further large-scale clinical trials to confirm these findings.

Background/aims: Finite nucleos(t)ide analog (NA) therapy has been proposed as an alternative treatment strategy for chronic hepatitis B (CHB), but biomarkers for post-treatment monitoring are limited. We investigated whether measuring hepatitis B core-related antigen (HBcrAg) after NA cessation may stratify the risk of subsequent clinical relapse (CR).

Methods: This retrospective multicenter analysis enrolled adults with CHB who were prospectively monitored after discontinuing entecavir or tenofovir with negative HBeAg and undetectable HBV DNA at the end of treatment (EOT).

Background: Emerging laboratory and animal studies suggest that aspirin may prevent non-alcoholic fatty liver disease (NAFLD)-related hepatocellular carcinoma (HCC), however clinical evidence remains lacking.

Methods: Using Taiwan's National Health Insurance Research Database, we screened 145,212 NAFLD patients from 1997 through 2011. After excluding any confounding conditions, 33,484 patients who continuously received a daily dose of aspirin for 90 days or more (treated group), along with 55,543 patients who had not received antiplatelet therapy (untreated group), were respectively recruited.

Article Synopsis
  • * Researchers found that about 1.8% of patients experienced severe flares with hepatic decompensation within four years after discontinuing NUCs, with higher risks for those with cirrhosis, portal hypertension, older age, and male sex.
  • * The findings suggest that stopping NUC therapy should be approached cautiously in clinical practice, as severe complications can occur in a small percentage of patients.

Article Synopsis
  • Identifying germline pathogenic variants in cancer patients is essential for effective treatment and genetic counseling, particularly in pancreatic ductal adenocarcinoma (PDAC) cases.
  • Previous studies likely underestimated the prevalence of these variants in PDAC due to limited focus on only certain gene regions.
  • A recent cohort study utilizing whole genome sequencing found that 33.3% of PDAC patients had pathogenic variants, indicating that many more might exist beyond traditional sequencing methods.

Background: Helicobacter pylori infection is an important causal factor of gastric cancer and peptic ulcer disease and is associated with immune thrombocytopenic purpura and functional dyspepsia. In H pylori strains, point mutations in the 23S rRNA and gyrA genes are associated with clarithromycin resistance and levofloxacin resistance, respectively. Whether the efficacy of molecular testing-guided therapy is non-inferior to that of susceptibility testing-guided therapy for H pylori eradication is unclear.
