Abstract

BACKGROUND/AIMS:

Gastric cancer (GC) is the second leading cause of cancer-related deaths worldwide and is the most frequent cancer in Iran. Epstein-Barr virus (EBV) has been shown to be associated with gastric cancer. The present study was carried out to investigate the prevalence of Epstein-Barr virus (EBV) associated gastric cancer among Iranian patients.

METHODS:

Ninety formalin fixed paraffin-embedded cases of gastric cancer were studied. The specimens were investigated for the presence of the EBV genome by quantitative real-time polymerase chain reaction.

RESULTS:

Of ninety specimens, EBV was detected in six cases (6.66%). The mean age for patients EBV-positive gastric carcinomas was 72.1 years, whereas the mean age for the entire group was 65.7 years. Four out of 64 (6.25%) male patients and 2 out of 26 (7.69%) female cases were positive for EBV. According to anatomic location, EBV was detected in 4 out of 39 (10.25% ) gastric cancer were located in cardia and 2 out of 26 (7.69%) gastric cancer were located in middle/corpus.

CONCLUSIONS:

The present study shows that the frequency of EBV-associated gastric carcinoma in Iran isĀ  low. Differences of EBV-associated gastric carcinoma incidence in different countries may reflect the epidemiologic factors and dietary habits. Further analysis of clinical pathology features of EBV-associated gastric carcinoma using a larger number of cases would give invaluable insights into its etiology.
