Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
* What is the spatial distribution pattern of metastatic lymph nodes in patients with colorectal cancer?
* Can the spatial distribution pattern of metastatic lymph nodes in patients with colorectal cancer guide clinical practice? Participants should undergo regular follow-up examinations for at least 5 years after the surgery.
