Malignancy
NO
To reveal the factors associated with metachronous and synchronous gastric and esophageal cancers in patients after endoscopic submucosal dissection (ESD) for primary early gastric cancer
Efficacy
The 5-year cumulative incidence rate of metachronous gastric cancers according to smoking in Helicobacter pylori (H. pylori)-eradicated patients who underwent ESD for early gastric cancers
1) The association between the incidence of metachronous gastric cancer (MGC) and smoking, drinking, body mass index, diabetes mellitus, preferences for salty taste, intake of green vegetables, intake of green tea, gastric atrophy diagnosed by endoscopy, and pepsinogen (PG) level before eradication of H. pylori
2) The association between the incidence of MGC and the detailed information of smoking
3) The establishment of cut-off value of PG level after H. pylori eradication for predicting the incidence of MGC
4) The comparison of cumulative incidence rate of MGC between H. pylori-eradicated cases and H. pylori-negative cases (those who never underwent H. pylori eradication)
5) The association between incidence of MGC and PG level before eradication of H. pylori
6) The association between incidence of MGC and change rate of PG level before and after eradication of H. pylori
7) The association between incidence of synchronous gastric cancer and factors related to life-style, H. pylori, and PG level
8) The incidence rate of esophageal cancer and factors associated with the incidence of esophageal cancer in patients who underwent ESD for early gastric cancer
9) The cumulative incidence rate of MGC and factors associated with the incidence of MGC in patients who underwent ESD for primary early gastric cancer that occurred in H. pylori-eradicated patients
10) The location of MGC
11) The association between incidence of synchronous gastric cancer and ALDH2-genotype, ADH1B-genotype, or the alcohol intake
12) The association between incidence of MGC and ALDH2-genotype, ADH1B-genotype, the alcohol intake, or cessation of drinking
13) The association between incidence of esophageal cancer in patients who underwent ESD for early gastric cancer and ALDH2-genotype, ADH1B-genotype, the alcohol intake, or cessation of drinking

In H. pylori-infected patients, H. pylori eradication will be performed, and their serum PG will be measured. Examination by esophagogastroduodenoscopy (EGD) will be performed 6 months after ESD for early gastric cancer. Annual EGD and assessment of smoking and drinking will be performed after ESD.
