Abstract

Abstract Gastric cancer is the second leading cause of cancerrelated deaths worldwide and it seems that environmental and lifestyle factors and infection with Helicobacter pylori (H.pylori) have had a major role in the etiology of gastric cancer. The aim of this study was to investigate the presence of H. pylori DNA in archival gastric tissues of patients with gastric cancer disease by rapid, sensitive and specific technique of Scorpion Realtime PCR. This retrospective cross-sectional study was performed on 285 paraffin embedded gastric specimens of patients who were pathologically proved for gastric cancer admitted in Bou- Ali, Shahid Rajaie and Dehkhoda hospitals and Bahar and Farzam private laboratory in Qazvin city in Iran during 2009 and 150 paraffin embedded pathological specimens of patients with other proved diagnosis other than gastric cancer. Results of our Scorpion Realtime PCR analysis showed that DNA of H. pylori DNA was present in 78.42 % of our total specimens. Modified McMullen’s Staining of paraffin embedded sections was positive in 210 patients. Also we were not able to finding significant relationship between demographic characteristics of our studied patients and presence of H. pylori DNA in their formaldehyde fixed paraffin embedded gastric tissues samples. Existence of H. pylori in gastric tissue samples of patients with gastric cancer is controversial and our results indicated that in our studied specimens prevalence of H.pylori was significantlymore than recent published reports.
