Objective:
-To gather data about hereditary gastric cancer.
Eligibility:
- People at least 2 years old with personal or family history with a hereditary gastric cancer.

Design:
- Participants will be screened in a separate protocol.
- Participants will have:
- Physical exam

- Photos of skin lesions and other findings
- Gynecology consultation for women
- Cheek swab (some participants)
- For some participants, their relatives will be asked to join the study.
- Some participants will be asked to allow the study to get stored tissue samples for relatives who have died.
- Some samples will be sent to outside labs. All personal data will be protected. Samples will be destroyed when the study ends.

Read the detailed description
Background:
An estimated 1-3% of gastric cancer cases occur within a familial background as part of an inherited cancer syndrome.
Hereditary Diffuse Gastric Cancer (HDGC) is the most frequent form of familial gastric cancer and has been linked to a germline mutation in the CDH1 gene.
Gastric Adenocarcinoma and Proximal Polyposis of the Stomach (GAPPS) is a more recently described autosomal dominant syndrome characterized by fundic gland polyposis with antral sparing.
Other germline mutations that predispose to gastric cancer such as SDH (succinate dehydrogenase protein subunits) gene and CTNNA1 (alpha catenin).
Objectives:
Characterize the natural and clinical histories of hereditary gastric cancer syndromes.
Eligibility:
Individuals, and family members, who fulfill clinical criteria for a hereditary gastric cancer syndrome irrespective of previous genetic testing or treatment.
Design:
These rare families will be recruited to genetically confirm diagnosis and study the natural history of hereditary gastric cancers.
Genetic testing will be offered to gain appreciation of the effect of mutations on the relative activity of various germline and somatic mutations.
We will determine if there is a relationship between mutation and disease phenotype.

Questions about this trial
What is this clinical trial studying?
An observational study of Stomach Neoplasms and Stomach Cancer, run by National Cancer Institute (NCI) at 1 site in United States.
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 0 inclusion and 1 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: finished, as of the sponsor's last update on 5 Nov 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 United States. 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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Characterization of the natural and clinical histories of hereditary gastric cancer syndromes (time frame: 10 years). 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 NCT03030404, which also lists 9 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 5 Nov 2026.
