Title: Long-term Outcomes of Additional Surgery Versus Surveillance-Only Clinical
Decision for Early Colorectal Cancer Patients After Non-curative Endoscopic Resection: A
Meta-analysis
Version: 2 Date: 18 Jul 2024
Reviewer's report:
1. In the discussion section, the author mentioned “Li et al concluded that surveillance in patients
who receive non-curative ESD may be an alternative option for those with advanced age and
fewer high-risk factors for residual cancer or LN metastasis”, “the more preferred option for
these patients maybe additional surgery”. There are problems in the logical relationship between
these two paragraphs. The previous article concluded that only surveillance should be considered
for special groups such as the elderly, while the conclusion proposed by the author is for all
patients with early colorectal cancer who receive non-curable resection, this logic is confusing.
If the author wants to show that additional surgery should be performed all patients with early
colorectal cancer who receive non-curable resection, especially the elderly, he may consider
adding a subgroup analysis of the elderly.
2. There are some grammatical problems in the article, please revise it.
