CtDNA-guided Selection of Adjuvant Chemotherapy Regimens for Elderly Colon Cancer Patients After Surgery: a Single-center, Randomized, Controlled Study

• Status: RECRUITING
• Trial end date: 2034-12-31

Summary

The goal of this clinical trial is to explore the disease-free survival period of elderly patients with high-risk stage II and stage III colon cancer based on ctDNA detection. The main questions it aims to answer are:

Can ctDNA detection effectively guide the assessment of disease-free survival in elderly patients with high-risk stage II and stage III colon cancer? What is the correlation between postoperative ctDNA status and patient imaging as well as prognosis in elderly patients?

Secondary objectives include:

Evaluating the correlation between postoperative ctDNA status and patient imaging, as well as prognosis, in elderly patients.

Analyzing the positive rate of postoperative ctDNA and the ctDNA clearance rate.

Additionally, an exploratory objective of this study is to investigate recurrence models for postoperative patients.

Participants will undergo ctDNA testing to assess their disease status and will be monitored for disease-free survival. Imaging studies will also be conducted to correlate with ctDNA findings. The study aims to gain a deeper understanding of the role of ctDNA in predicting prognosis and monitoring disease recurrence in elderly patients with colon cancer.
