NCT ID NCT01514045
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is building a registry of people with gastric cancer, a family history of it, or a specific gene mutation (CDH1). Participants fill out online questionnaires and provide saliva, blood, or tissue samples. The goal is to learn more about what causes stomach cancer and how genetics might affect treatment and survival. No new treatments are being tested.
