Aim: This case-control study investigated the effects of kimchi, soybean paste, fresh vegetables, nonfermented alliums, nonfermented seafood, nonfermented soybean foods, and the genetic polymorphisms of some metabolic enzymes on the risk of gastric cancer in Koreans.
Methods: We studied 421 gastric cancer patients and 632 age- and sex-matched controls. Subjects completed a structured questionnaire regarding their food intake pattern. Polymorphisms of cytochrome P450 1A1 (CYP1A1), cytochrome P450 2E1 (CYP2E1), glutathione S-transferase mu 1 (GSTM1), glutathione S-transferase theta 1 (GSTT1) and aldehyde dehydrogenase 2 (ALDH2) were investigated.
Results: A decreased risk of gastric cancer was noted among people with high consumption of nonfermented alliums and nonfermented seafood. On the other hand, consumption of kimchi, and soybean pastes was associated with increased risk of gastric cancer. Individuals with the CYP1A1 Ile/Val or Val/Val genotype showed a significantly increased risk for gastric cancer. Increased intake of kimchi or soybean pastes was a significant risk factor for the CYP1A1 Ile/Ile, the CYP2E1 c1/c1, the GSTM1 non-null, the GSTT1 non-null, or the ALDH2 *1/*1 genotype. In addition, eating soybean pastes was associated with the increased risk of gastric cancer in individuals with the GSTM1 null type. Nonfermented alliums were significant in individuals with the CYP1A1 Ile/Ile, the CYP2E1 c1/c2 or c2/c2, the GSTT1 null, the GSTT1 non-null, or the ALDH2 *1/*2 or *2/*2 genotype, nonfermented seafood was those with the CYP1A1 Ile/Ile, the CYP2E1 c1/c1, the ALDH2 *1/*1 genotype or any type of GSTM1 or GSTT1. In homogeneity tests, the odds ratios of eating kimchi for gastric cancer according to the GSTM1 or GSTT1 genotype were not homogeneous.
Conclusion: Kimchi, soybean pastes, and the CYP1A1 Ile/Val or Val/Val are risk factors, and nonfermented seafood and alliums are protective factors against gastric cancer in Koreans. Salt or some chemicals contained in kimchi and soybean pastes, which are increased by fermentation, would play important roles in the carcinogenesis of stomach cancer. Polymorphisms of the CYP1A1, CYP2E1, GSTM1, GSTT1, and ALDH2 genes could modify the effects of some environmental factors on the risk of gastric cancer.

We report the case of a 68-year-old female patient who had a gastrointestinal stromal tumor involving muscularis propria of the gastric body that was removed through submucosal tunneling endoscopic resection, with favorable follow-up after 5 years, with no signs of recurrence.

The role of Helicobacter pylori in the pathogenesis of peptic ulcers and gastric adenocarcinoma is widely known; however, it is not entirely understood how bacterial infection is closely related to the genesis of follicular gastritis and some types of gastric lymphoma. Diagnosing and pathogenic mechanisms follicular gastritis remain challenging. Therefore, this article aims to examine the role of H.

Helicobacter pylori (H. pylori) is the primary etiological agent of gastric adenocarcinoma, which affects over 60% of the global population, with a significant prevalence in Latin America. Given its impact on the affected population, it is crucial to understand the diagnostic tools available for detecting this infection.

Unlabelled: Endoscopic submucosal dissection (ESD) is the technique of choice in the management of early gastric cancer. Recently, it is also considered as an absolute indication in selected cases of early undifferentiated gastric cancer (U-EGC).
Objectives: In the present study, the first documented cases of ESD in patients with U-EGC are presented and analyzed.
