Insights

Epstein Barr virus (EBV) may be linked to unique features in cardial gastric cancer. While not statistically significant, EBV-positive tumors showed trends toward specific appearances and survival rates.

Area of Science:

  • Gastroenterology
  • Oncology
  • Virology

Context:

  • Cardial gastric cancer mortality is rising in Chile.
  • Previous research indicated a link between Epstein Barr virus (EBV) and this cancer subtype.

Purpose:

  • To conduct a clinical and molecular characterization of cardial gastric cancer associated with EBV.
  • To compare clinical and pathological features, survival rates, and protein expression (p53, c-erbB2) between EBV-positive and EBV-negative tumors.

Summary:

  • Epstein Barr virus was detected in 23.6% of 93 cardial gastric tumors using in situ hybridization.
  • EBV-positive tumors showed a trend towards Bormann III endoscopic appearance and lower p53 accumulation.
  • Five-year survival rates were 67% for EBV-positive tumors versus 42% for EBV-negative tumors, though not statistically significant.

Impact:

  • The study suggests potential unique characteristics of EBV-associated cardial gastric cancer.
  • Findings may inform future research into targeted therapies and diagnostic markers for this specific cancer subtype.

Barrett Esophagus-I: Introduction

Barrett's esophagus is a medical condition where the esophageal mucosa is significantly damaged by stomach acid or other digestive fluids, often due to long-term exposure associated with gastroesophageal reflux disease (GERD). In GERD, a weakened or abnormally relaxed lower esophageal sphincter allows stomach acid to flow persistently into the esophagus.
This constant acid exposure transforms the esophagus's pink mucosal lining (stratified squamous epithelium) into a type of lining more similar...

Barrett Esophagus-II: Clinical Manifestations and Management

Individuals with Barrett's esophagus are often asymptomatic, but they may experience symptoms commonly associated with GERD, such as heartburn and acid regurgitation. Additional symptoms can include difficulty swallowing, chest pain, unintentional weight loss, blood in the stool (which may appear black, tarry, or bloody), and episodes of vomiting.
To diagnose Barrett's esophagus, healthcare providers often recommend an endoscopy for those showing symptoms of acid reflux. The procedure entails...

Gastritis II: Pathophysiology

The pathophysiology of gastritis begins with the colonization of the stomach lining by Helicobacter pylori (H. pylori). This bacterium spreads mainly via the oral-oral route through saliva or shared utensils, and can also be transmitted in overcrowded or unhygienic environments through contaminated water, despite its brief survival outside the body.ColonizationOnce ingested, H. pylori enters the stomach and begins colonization by navigating through the mucus layer lining the stomach wall. It...

Rous Sarcoma Virus (RSV) and Cancer

Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
RSV is a retrovirus that contains two copies of a plus-strand  RNA genome. Its genome consists of four main open...
