Reviewer's report:
I have these questions to ask the author:
1. On page 13, lines 10-13, I don't quite understand the meaning of the
sentence"According to the tumor malignant stage, tumor size, tumor marker and
lymphnode metastasis were not different between the two groups, with statistical
difference",please explain.
2.Do you have any reference standards 
for choosing inflammatory nutritional
factors?Why did you choose "NLR""NLR""mGPS""CRP/Alb'' 
for 
inflammatory
nutritional factors?
