Eligibility Criteria:
Inclusion Criteria:~* The patients who tested serum PG concentration test and H. pylori status at the time of ESD and revealed pathologically complete en bloc resection after ESD for EGC.~Exclusion Criteria:~* previous history of ER; proven pathologically incomplete resection or lympho-vascular invasion on the resected ESD specimen; additional treatment after ESD; and follow-up loss less than 2 years.

- Gender: ALL
- Minimum Age: 18 Years

- Healthy Volunteers: t

Study Arms:
- Negative H. pylori group (Type: None): The participants revealed negative findings of H pylori IgG and other invasive methods (rapid urease test or histology) at the time of ESD for EGC
- Previous H. pylori infection group (Type: None): The participants revealed positive findings of H pylori IgG and other invasive methods (rapid urease test or histology) at the time of ESD for EGC
- Eradicated H. pylori group (Type: None): The participants revealed to success for H. pylori eradication in those who were positive findings of H pylori IgG and other invasive methods (rapid urease test or histology) at the time of ESD for EGC
- Persistent H. pylori group (Type: None): The participants revealed to fail in H. pylori eradication in those who were positive findings of H pylori IgG and other invasive methods (rapid urease test or histology) at the time of ESD for EGC
