Title: Conditional survival and the prognostic value of serum carcinoembryonic antigen level
in oldest old with colorectal cancer
Version: 2 Date: 03 Mar 2023
Reviewer's report:
The conclusion of this paper that high CEA levels in elderly patients have a worse prognosis
does not have any clinical impact.
In the abstract, the context flow is awkward, and there is no mention of stages according to
CEA levels in the method part. Furthermore, it seems unnecessary to mention the Kaplan-Meier
method.
In Table 2, it seems strange that chemotherapy was seen as a poor prognostic factor in the
univariate analysis, but was seen as a good prognostic factor in the multivariate analysis.
