Distribution and Analysis of Metastatic Lymph Nodes in Colorectal Cancer Patients (DIAMOND)
Source: ClinicalTrials.gov · Last updated 9 Jun 2026
Brief summary (registry, in English)
The goal of this observational study is to learn about the spatial distribution and significance of metastatic lymph nodes in colorectal cancer patients. The main question it aims to answer is: * 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.
