About this study

Official title: Based on the Application of Peripheral Blood Polygene Methylation Markers in Postoperative Recurrence Monitoring of Colorectal Cancer

This study dynamically monitored the prognosis of stage I-IV colorectal cancer patients who could receive radical surgical resection by detecting the levels of polygene methylation in plasma samples from patients with colorectal cancer. In patients with colorectal cancer feasible radical surgery, plasma ctDNA methylation detection was performed before and after surgical treatment and during regular follow-up to explore the predictive effect of plasma ctDNA methylation status at different time points on postoperative recurrence. To explore whether postoperative dynamic monitoring of plasma ctDNA methylation can be used for adjuvant chemotherapy efficacy evaluation and whether it can indicate tumor recurrence and metastasis earlier than imaging examination.

Read the detailed description
  1. Patients initially diagnosed with primary colorectal cancer were enrolled for screening, and plasma samples 1-2 days before radical bowel resection were collected for polygene methylation detection.
  2. The postoperative follow-up was 2 years, and the reexamination included CT/MRI imaging assessment, blood CEA, and dynamic monitoring of plasma ctDNA methylation level. Blood samples were collected for 9 times.
  3. Results analysis: To explore the application value of ctDNA methylation-MRD detection in the prediction of postoperative tumor recurrence risk after radical resection of colorectal cancer; The correlation between preoperative ctDNA methylation level and prognosis of early colorectal cancer.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

Study groups in NCT05444491
Study groupRoleWhat they receive
MRD positive groupColonAiQ polygene methylation test was performed on peripheral blood plasma samples from the enrolled patients 4 weeks after surgery. If gene methylation levels in the samples exceeded the threshold, the patients were enrolled in the MRD positive group. The 2-year total tumor recurrence rate of patients in the MRD positive group was calculated, and the positive prediction rate of postoperative plasma ctDNA methylation-MRD detection results for 2-year tumor recurrence rate after colorectal cancer radical resection was calculated.
MRD negative groupColonAiQ polygene methylation test was performed on peripheral blood plasma samples from the enrolled patients 4 weeks after surgery. If the gene methylation level detected in the samples did not exceed the threshold, the patients were enrolled in the MRD negative group. The 2-year total tumor recurrence rate of patients in the negative MRD group was calculated, and the negative prediction rate of postoperative plasma ctDNA methylation-MRD test results for 2-year tumor recurrence rate after radical resection of colorectal cancer was calculated.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. To establish a clinical cohort for colorectal cancer

    It is expected that 800 patients with primary colorectal cancer diagnosed clinically will be enrolled for screening. Plasma samples 1-2 days before radical bowel resection will be collected for ColonAiQ polygene methylation test. Follow-up will be conducted 2 years after surgical resection, including CT/MRI imaging evaluation and blood CEA, etc. And dynamic monitoring of plasma ctDNA methylation level. Blood samples were collected for 9 times.

    Measured: assessed up to 36 months

  2. To investigate the prediction and monitoring effect of plasma ctDNA methylation on postoperative recurrence of primary colorectal cancer patients after radical surgery

    To investigate the role of peripheral plasma ctDNA methylation level at different time points in the monitoring of disease recurrence after radical bowel resection for primary colorectal cancer, the multi-gene methylation detection of peripheral plasma ctDNA was conducted before, after and during the postoperative follow-up period.

    Measured: assessed up to 36 months

Is this clinical trial currently recruiting?

The record says: under way, not looking for participants, as of the sponsor's last update on 31 Jul 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 7 sites in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

To establish a clinical cohort for colorectal cancer (time frame: assessed up to 36 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05444491, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 31 Jul 2025.
