A Study Collecting Health Information to Understand and Prevent Gastric Cancer
What this study is about
The purpose of this study is to create a registry of participants with precursor lesions for gastric cancer, including gastric atrophy, intestinal metaplasia, and dysplasia. Normal controls and individuals with gastric cancer for comparison of baseline characteristics will also be enrolled.

Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Age ≥ 18 years old
- Able to read and understand English and Spanish
- Meet criteria for one of three potentially eligible study populations:
- Individuals with gastric atrophy, gastric intestinal metaplasia, or dysplasia: Had a previous diagnosis of or have been diagnosed by the investigation team with gastric atrophy, gastric intestinal metaplasia, or dysplasia of the gastric mucosa on pathology review from an endoscopic biopsy. Individuals who have a prior history of early gastric cancer may be included, if they were treated endoscopically and have no evidence of disease. Individuals who have a prior history of a cancer other than upper gastrointestinal cancer may also be included, if they have no evidence of disease for at least 1 year prior to study enrollment and are not undergoing active treatment for any malignancy at any time throughout the study period
- Healthy controls (average risk): Individuals with no history of cancer or gastric precursor lesions undergoing a clinically indicated endoscopy at MSK for workup or dyspepsia or reflux
- Gastric cancer cases: Individuals with a known diagnosis of early gastric adenocarcinoma undergoing surgical resection at MSK
Exclusion criteria
- Age \< 18 years old
- Women who are pregnant (may be enrolled after delivery)
- Individuals with a prior history of upper gastrointestinal surgery or a prior cancer who are undergoing active treatment for malignancy or have been diagnosed within 1 year prior to the study enrollment or with pancreatic cancer. (This does not include incidentally diagnosed primary gastric adenocarcinoma identified during study follow up. Individuals diagnosed with gastric carcinoid limited to the stomach will also be included, given their ongoing parallel risk for gastric adenocarcinoma.)
- Have severe comorbidities with expected survival time \<2 years or which would prevent them from undergoing routine elective EGD (at the discretion of the patient's provider and the study team)
- Individuals having Hereditary Diffuse Gastric Cancer Syndrome, mutations including CDH1 and CTNNA1, or more than one genetic mutation
- Exclude high risk esophageal and duodenal lesions including:
- Duodenal Adenoma
- Dysplasia or cancer at the esophagus or gastroesophageal junction
- Patients with an increased risk for biopsies during EGD, such as those with clotting disorders.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
