Study showed that majority of gastric cancer after Helicobacter pylori eradication develop in the endoscopic atrophic mucosa or at atrophic border, which is characterized as high degrees of histological atrophy and intestinal metaplasia. The endoscopic surveillance of gastric cancer after H. pylori eradication should be performed, always pay careful attention to the atrophic area.

2. What is/are the hypothesis? NA

 

 

 

3. What is/are the research Question(s)? Are there any possibilities that after helicobacter pylori eradication has a link between gastric mucosal atrophy and gastric cancer?

Urea breath test and histological assessments using endoscopic biopsy specimens obtain from non-pathological mucosa of the greater curvature of the gastric antrum and upper corpus.

 

 

 

 

 

Discussion (6 marks)
1. Strength of the study Study showed that majority of gastric cancer after Helicobacter pylori eradication develop in the endoscopic atrophic mucosa or at atrophic border, which is characterized as high degrees of histological atrophy and intestinal metaplasia. The endoscopic surveillance of gastric cancer after H. pylori eradication should be performed, always pay careful attention to the atrophic area.

 

 

 

2. Limitations of the study The study deserves more intensive study to establish the strategy for the early diagnosis, treatment and prevention of gastric cancer after H. pylori eradication.
