Disease

Reviewer's report:  
 
The authors made a substantial effort and improved the manuscript which can be published after 
the following minor change will be performed:  
 
It is not correct to include NECs under the term GNEN type 3. The most optimal is to pr esent 
type 3 (well differentiated) separately from NECs (poorly differentiated). An alternative solution, 
if the previous will not be performed, is that the authors will add a meaning that they used the 
GNEN term including both Type 3 and NECs (and not as it is presented that GNEN type 3 
encompass also NECs). Likewise, a similar change it is suggested to be made at the table 1 page 
29 where Type 3 column appears (the column should be named GNEN and underneath to 
explain that includes both type 3 and NECs). Otherwise someone can argue, as I mentioned in 
my first review of the manuscript, that the classification is not correctly presented as type 3 
lesions are well differentiated and NECs are poorly differentiated lesions.
