Reviewer's report:  
 
A retrospective series of endoscopic cases of oesophageal a nd gastric cancers in the North 
eastern region of Turkey. It is not a randomized controlled trial nor has an inbuilt control arm, 
hence its weakness. Nevertheless, this is an article worthwhile of reading, as it describes the 
epidemiological differences of gastric cancers in different pa rt of Turkey, hence a different 
screening strategy should be adopted.  
 
 
The study adds to the body of evid ence that gastric cancer freque ncy and characteristics is very 
much region dependent, and this affects the screening, diagnosti c and treatment effort. It is a 
large series, and written in clear language, which makes it an interesting article on upper GI 
cancers epidemiology.
