NCT06798857Completed
Exploration of the Relationship Between Mismatch Repair Status of Colorectal Cancer and Lymph Node Metastasis Patterns and Pathological High-risk Factors
Source: ClinicalTrials.gov · Last updated 2 Dec 2025
Brief summary (registry, in English)
This study analyzed the differences in clinical baseline features and survival outcomes between pMMR and dMMR patients. The aim is to evaluate the impact of MMR status on overall survival and disease-free survival of colorectal patients, and to explore the population exempt from extended resection, so as to provide evidence-based medical evidence for the relationship between MMR status, lymph node metastasis pattern and clinicopathological risk factors in colon cancer patients.
