Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • Healthy volunteers accepted
  • Adult, Older adult

Study population: Subjects for this clinical study were obtained from inpatients and outpatient follow-up patients attending the sub-center. Subjects will be identified by the investigator based on subject entry criteria and informed of the contents of the informed consent form. Subjects will have their feces collected at the time of clinic visit or at the time of physical examination and will be tested for fecal methylated DNA and H. pylori gastric cancer susceptibility genes.

Who may be able to join

  • Age ≥ 18 years old, male or female not limited.
  • Within 90 days, the gastroscopy and/or pathological results confirm the absence of gastric cancer.
  • Patients must be able to fully understand the informed consent form and be able to personally sign it.

Who cannot join

  • Severe heart, liver, kidney dysfunction, or mental illness.
  • History of malignant tumors in the upper gastrointestinal tract.
  • Pregnant women.
  • Those with unclear pathology.
  • Those with unsatisfactory sample retention (such as insufficient sample size).

About this study

Official title: Application of Fecal DNA Methylation and Fecal Helicobacter Pylori Gastric Cancer Susceptibility Genes in Clinical Diagnosis, Treatment, and Relapse and Metastasis of Gastric Cancer

Based on the detection technology of methylation sites in feces, combined or not combined with Helicobacter pylori gastric cancer susceptibility gene detection, an early diagnosis and detection system for gastric cancer is established, and the clinical diagnostic value of the detection system is evaluated. In addition, the study observed the association between different loci and post-treatment recurrence, metastasis, or long-term survival rate through long-term follow-up of gastric cancer patients; Follow up with individuals with benign diseases such as gastritis and healthy individuals, compare cases of gastric cancer, and compare their sample data during follow-up with controls who did not have the disease.

Being tested
Diagnostic Test: fecal methylation site-based testing and fecal Helicobacter pylori gastric cancer susceptibility gene-based testing
Medical subject headings
Stomach Neoplasms

What participants receive

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

  • Diagnostic Test: fecal methylation site-based testing and fecal Helicobacter pylori gastric cancer susceptibility gene-based testingDiagnostic test

    To establish an early diagnostic test system for gastric cancer based on the methylation site detection technology in feces, with or without the combination of Helicobacter pylori gastric cancer susceptibility gene detection, and then to evaluate the clinical diagnostic value of this test system.

What is being measured

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

  1. Positive predictive value of early diagnosis of gastric cancer

    Measured: baseline

Questions about this trial

What is this clinical trial studying?

An observational study of Gastric (Stomach) Cancer, run by Fudan University at 1 site in China.

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 3 inclusion and 5 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: under way, not looking for participants, as of the sponsor's last update on 31 Dec 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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?

Positive predictive value of early diagnosis of gastric cancer (time frame: baseline). 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 31 Dec 2025.
