Brief Summary

After endoscopic resection of early gastric cancer (EGC), there remained concerned about the development of the metachronous gastric neoplasm (MGN). The aim of this study was to evaluate the role of H. pylori eradication for reducing MGN after ESD and the efficacy of serum pepsinogen (PG) for predicting development of MGN after endoscopic submucosal dissection (ESD) for EGC and to evaluate other risk factors for the incidence of MGN. The investigators enrolled the participants who were tested serum PG I and II at the time of ESD for EGC, from January 2007 to May 2013 in single tertiary center, retrospectively. The baseline characteristics of the participants, H. pylori status, and serum pepsinogen were analyzed for the development of the MGN.

Outcome Measures

Primary Outcomes (1)

  • To estimate the incidence (number of participants) of metachronous gastric neoplasm after ESD between H. pylori eradicated group and H. pylori persistent group

    The investigators were estimated the number of participants who found metachronous gastric neoplasm after ESD for EGC during follow up endoscopic surveillance. Then, the investigator will evaluate the statitistical difference in the incidence of the development of metachornous gastric neoplasm between H. pylori eradicated group and H. pylori persistent group.

    Up to 8 years after ESD for EGC

Secondary Outcomes (1)

  • To evaluate the incidence of metachronous gastric neoplasm after ESD based on diffferent cut off point of serum pepsinogen.

    Up to 8 years after ESD for EGC

Study Arms (4)

Negative H. pylori group

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

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

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

Drug: H pylori eradication

Persistent H. pylori group

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

Drug: H pylori eradication

Interventions

The regimen of H. pylori eradication was like that: 1-week conventional proton pump inhibitor (PPI) based triple therapy (lansoprazole 40 mg b.i.d., clarithromycin 500 mg b.i.d., and amoxicillin 1 g b.i.d. for a week) after confirmation of H. pylori infection. If the participants who initially failed to respond to the first eradication, they recommended to underwent second-line eradication therapy with the regimen of 7-day bismuth containing quadruple regimen \[lansoprazole 40 mg b.i.d., tripotassium dicitrate bismuthate (Denol; Greencross Co., Seoul, Korea) 300 mg q.i.d. (three tablets 30 min before meals and one tablet 2 hours after dinner), metronidazole 500 mg t.i.d., and tetracycline 500 mg q.i.d. for 1 week\]

Study Population

This study was designed to enroll patients in our ESD data registry, prospectively. Finally, we analyzed the data retrospectively. We enrolled about more than 1000 patients in our ESD registry. For this cohort study, we enrolled about 800 patients for analysis.

You may qualify if:

  • 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.

You may not qualify if:

  • 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.
