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

Study population: Subjects were recruited mainly from communities in Tongling, Anhui Province. The subjects were identified by the investigator based on the enrollment criteria and were informed about the contents of the informed consent form.

Who may be able to join

  • Age ≥40 years, male or female.
  • No contraindications to endoscopy and able to cooperate with endoscopy.
  • Patients must be able to fully understand the informed consent form and be able to sign the informed consent form in person.

Who cannot join

  • A history of diagnosed gastric cancer or other malignant tumors of the digestive tract.
  • Comorbid severe underlying conditions (e.g., severe cardiopulmonary insufficiency, liver or renal failure, etc.) that are likely to result in a short life expectancy or render long-term follow-up impractical.
  • Severe mental illness or incapacity to participate in the study due to lack of civil behavior.

About this study

Official title: A Prospective Study of Gastric Cancer Screening Based on Fecal Multi-Target DNA Analysis Combined With a Risk Questionnaire

This is a prospective study designed to evaluate the efficacy of a multi-target fecal DNA test for the early detection of gastric cancer. The test combines Helicobacter pylori gene detection with analysis of fecal methylated DNA markers. The primary objective is to assess whether each method, individually or in combination, can facilitate earlier diagnosis of gastric cancer. All participants will undergo the multi-target fecal DNA test and complete the gastric cancer risk questionnaire.

Read the detailed description

Sample Selection:

The study will be conducted in selected communities within Tongling City, with a total of 10000-15000 residents recruited

Participants Recruitment:

  • Participation is voluntary. All subjects must provide written informed consent at the time of recruitment.
  • Well-trained investigators will conduct face-to-face interviews to administer the gastric cancer risk questionnaire.

Tests and Follow-up:

  • Initial Screening: All participants will provide a stool sample for the multi-target DNA analysis (including H. pylori susceptibility testing and methylated DNA markers) and complete a questionnaire.
  • Definition of Screening Positive: A participant will be considered screening positive if they test positive on the fecal multi-target DNA test or are identified as high-risk through the questionnaire.
  • Diagnostic Workup: All screening-positive individuals will be referred for a confirmatory diagnostic workup. Briefly, the endoscopist will conduct a fiberoptic endoscopy and perform a pathological biopsy.
  • Follow-up: Screening-positive individuals who are not diagnosed with gastric cancer in the first year will be entered into an annual follow-up program.
  • Biobanking: Residual fecal samples will be stored at the biobank of Fudan University Shanghai Cancer Center for future biomarker research.

What is being measured

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

  1. Sensitivity and specificity of the fecal multi-target DNA test and questionnaire screening for gastric cancer

    To compare the sensitivity and specificity of the fecal multi-target DNA test and questionnaire screening for gastric cancer.

    Measured: 2 years

Secondary outcomes (4)
  1. Positive and negative predictive values of the fecal multi-target DNA test and the questionnaire screening method

    To compare the positive and negative predictive values of the fecal multi-target DNA test and the questionnaire screening method

    Measured: 2 years

  2. Number needed to screen to identify one gastric cancer

    To calculate and compare the number of participants needed to screen to identify one case of gastric cancer using the fecal DNA test versus the questionnaire.

    Measured: 2 years

  3. Early diagnosis rate of gastric cancer

    To compare the early gastric cancer detection rate achieved by the fecal multi-target DNA testing and the questionnaire.

    Measured: 2 years

  4. Diagnosis rate of precancerous lesions associated with gastric cancer

    To compare the detection rate of the fecal multi-target DNA testing and the questionnaire for precancerous lesions associated with gastric cancer

    Measured: 2 years

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: looking for participants now, as of the sponsor's last update on 25 Feb 2026. 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?

Contact Dazhi Xu, PhD (86-18121299796, xudzh@fudan.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Sensitivity and specificity of the fecal multi-target DNA test and questionnaire screening for gastric cancer (time frame: 2 years). 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 25 Feb 2026.
