Version: 1 Date: 29 Jan 2020
Reviewer: Zuoyi Jiao
Reviewer's report:
Dear authors:
Thank you for inviting me to evaluate the article titled "The diffuse-type gastric cancer epidemiology
enigma". After I read this article carefully, I made the following suggestions:
1. It is recommended to add a table to compare the epidemiological characteristics of intestinal and
diffuse gastric cancer;
2. Since the author mentions that the incidence of diffuse gastric cancer has not decreased, it is
recommended that the authors comment on how to reduce the incidence;
3. It is recommended that the authors express their unique opinions on the diagnosis and treatment of
diffuse gastric cancer in the conclusion.
I sincerely hope that my suggestions can help you.
Yours sincerely
Zuoyi Jiao
