Reviewer’s report
Title: 
A competing risk analysis of colorectal cancer recurrence after curative
surgery
Version: 
0 
Date: 
11 Dec 2021
Reviewer's report:
In this study, author retrospectively analyzed the risk factors of colorectal cancer
recurrence and concluded that the pathological factors with the highest CIF of
recurrence were T4 stage, N2 stage, and vascular invasion, and the best model
for predicting recurrence was determined to be the univariable model for N-
stage. Although this study included a large sample size, the study was not
obviously innovative, and the risk factors obtained were all recognized risk
factors for CRC recurrence. The clinical value of this study is very limited, so
the author needs to explore the clinical significance of these data in depth.
