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.
Background:
Mortality caused by cardial gastric cancer in Chile, is increasing. Previously we demonstrated an association between Epstein Barr virus and this specific location of gastric cancer.
Aim:
To perform a clinical and molecular characterization of cardial gastric cancer associated to Epstein Barr virus.
Material And Methods:
Epstein Barr virus was identified in 93 cardial gastric tumors, by in situ hybridization. Clinical and pathological features, survival and expression of p53 and c-erbB2 were compared between tumors with or without the presence of the virus.
Results:
Twenty two (23.6%) tumors expressed Epstein Barr virus. No difference in sex or age of patients with tumors positive or negative for the virus was observed. Epstein Barr positive tumors had a tendency to have a higher frequency of Bormann III endoscopic appearance and a lower frequency of p53 accumulation (p=0.06). Five years survival was 67% and 42% of tumors positive and negative for the presence of the virus, respectively (p=0.57).
Conclusions:
Our results, although not significant, show a tendency towards unique characteristics of cardial gastric tumors associated to Epstein Barr.
