Reviewer's report:  
 
Thank you for the opportunity to review the manuscript, "Surgical Treatment and Prognosis of 
Gastric Neuroendocrine Neoplasms: A Singlecenter  
Experience".  Please see below for comments and questions:  
 
1.  Please make sure to su bmit your manuscript for English review.  There are several phrases 
and wordings throughout the paper which are not quite right.  
(ex.  Line 187 - "statistically significant significances").  
2.  Is there literature to support at D2 resection for gastric ne uroendocrine tumors?  
3.  It is not usually considered standard of care to operate on G3 lesions consistent with small 
cell NET.  Can you please provide the rationale for operating on the highly aggressive cohort?  
4.  What is the role for palliative resecti on in NET?  
5.  Lines 234 -237 - spell out abbreviations.  
6.  After controlling for tumor factors, was endoscopic resection still significant for overall 
survival?  
7.  In your discussion, there is a lot of talk about other NEN - small bowel, rectum, pancreas.  
Please confirm that the study is specific for "Gastric"?  
8.  Delete "and so on" line 326 -327. 
9.  Have you considered looking at the effect of chemo only in th e more advanced stage disease 
patients?  
10.  Please include a limitations paragraph.  
11.  What will be the next step in the research?  
12.  Stages I and II cross on the KM curve at 5 years.  Please comment.
