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: 
4 
Date: 
20 Sep 2020
Reviewer's report:
This article has been improved to some extent.
1. Page 8, Line 22-23; Authors described as "(1) compared with the 7th/8th
edition, the 6th edition T staging system may be more accurate and adaptable for
the EUS T stage". Instead of explaining that the old version is better than the
latest version, you had better explain the characteristics of latest version
compared to the old version. However, the comparison between older and
current editions itself may not be so significant.
