Reviewer’s report
Title: 
The impact of COVID-19 pandemic on colorectal cancer patients: A single-center retrospective
study
Version: 
1 
Date: 
27 Mar 2021
Reviewer's report:
The manuscript has been improved a lot. 
However, the sentence "As coronavirus is capable of transmission" need to be modified accordingly with
the other parts of the manuscript. 
I suggest to change it in " Due to the potential risk of fecal-oral transmission"
