About this study

Official title: A Multicenter, Observational Clinical Study Evaluating the Application of Multi-Omics Tumor-agnostic Technology for Localizing Postoperative Local Recurrence and Distant Metastasis in Colorectal Cancer

With high incidence and mortality rate, the effective therapeutic options of colorectal cancer remain limited. Up to 50% of patients with colorectal cancer will develop metastatic disease. Recurrent lesions can be diagnosed and characterized only when tumors have reached a certain volume by present radiologic imaging techniques such as CT and MRI. The exploration of differentiated clinical applications specifically for local recurrence versus distant metastasis remains an unmet need. The aim of this study is to explore methylation, fragmentomic, and cfRNA markers associated with local recurrence and distant metastasis of colorectal cancer by multi-omics approaches. By constructing a predictive model for the localization of post-treatment recurrence and metastasis, this study will compare the accuracy of different technical approaches in predicting the localization of recurrence and metastasis after colorectal cancer treatment.

What is being measured

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

  1. Area Under the Receiver Operating Characteristic Curve (AUC) of the prediction models based on methylation, fragmentomics, and cfRNA data for local recurrence and distant metastasis localization in colorectal cancer

    The AUC is calculated from the Receiver Operating Characteristic (ROC) curve to evaluate the discriminatory performance of the prediction model developed by use of methylation, fragmentomics, and cfRNA data. Model performance will be assessed on the validation cohort.

    Measured: At baseline (at the time of study enrollment, prior to any surgical or anti-tumor treatment)

Secondary outcomes (2)
  1. Accuracy of the prediction models based on methylation, fragmentomics, and cfRNA data for colorectal cancer recurrence and metastasis localization

    Accuracy is defined as the proportion of correctly predicted samples (true positives + true negatives) among the total number of samples in the validation cohort.

    Measured: Baseline (at enrollment)

  2. Sensitivity and specificity of individual omics technologies (methylation, fragmentomics, and cfRNA)

    Comparison of predictive performance of three individual technical approaches for localization of recurrent and metastatic lesions.

    Measured: Baseline (at enrollment)

Questions about this trial

What is this clinical trial studying?

An observational study of Metastatic Colorectal Cancer (CRC), run by The First Affiliated Hospital with Nanjing Medical University.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: opening soon, as of the sponsor's last update on 6 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.

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?

Contact Yanhong Gu, PhD (+025-68307881, YanhongGu@njmu.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Area Under the Receiver Operating Characteristic Curve (AUC) of the prediction models based on methylation, fragmentomics, and cfRNA data for local recurrence and distant metastasis localization in colorectal cancer (time frame: At baseline (at the time of study enrollment, prior to any surgical or anti-tumor treatment)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 6 Jul 2026.
