Reviewer’s report
Title: 
The New American Joint Committee on Cancer T Staging System for
Stomach: Increased Complexity without Clear Improvement in Predictive
Accuracy for Endoscopic Ultrasound
Version: 
3 
Date: 
25 Jul 2020
Reviewer's report:
The authors have almost satisfactorily reviewed their paper according to the
reviewers' criticisms.
However, a minor issue is still present under EUS equipment page 4 line 35
Please delete "A curved heteroscope with" and start the sentence with "A 360°
radial..."
As I have previously mentioned, the term "heteroscope" is wrong
