Title: Gastric cancer diagnosed after Helicobacter pylori era dication in diabetes mellitus patients

Reviewer ’s report:  
 
In this retrospective study including a relatively large series of patients, the authors show that th e 
incidence and main characteristics of gastric cancers developing after H pylori eradication are 
not different in DM and non -DM patients.  
 
It is a rather expected finding as the epidemiological reported link between DM and gastric 
cancer is probably multif actorial with particularly a higher rate of infection.The paper is well 
written.  
 
In my opinion, the authors should emphasize that in both groups of patients, the only 
significative risk factor was the presence of a severe gastric atrophy at the initial gas troscopy 
suggesting the need for an endoscopic surveillance.
