Trial Identification

Brief Title: Microbiota in Gastric Cancer by Gastric Mucosal Brushing

Official Title: Microbiota Diversity and Composition in Gastric Cancer by Gastric Mucosal Brushing: a Cross-sectional Case-control Study

Study ID: NCT06325891

Conditions

Gastric Cancer

Study Description

Brief Summary: Many studies have shown a significant change of diversity and composition in gut microbiota across the gastric carcinogenesis process, particularly in patients with gastric cancer. However, there has been no analysis of gastric microbiota using the mucosal brushing technique, despite its favoring benefit in microbiota study. Therefore, this study aims to evaluate microbiota profile in patients with gastric cancer, compared to those without gastric cancer by using mucosal brush sampling. This will improve current knowledge of the potential role of the microbiome in patient gastric cancer as a future biomarker marker using brushing sampling.

Detailed Description: * Gut microbiota play role in mucosal immune response and strength gut integrity. The dysbiosis or imbalance of microbiota changes microecology and activates the inflammation in gastrointestinal mucosa. It also has been implicated in gastric carcinogenesis. * Up to date, many studies have shown a significant change of diversity and composition in gut microbiota across the gastric carcinogenesis process, particularly in patients with gastric cancer. Although, Helicobacter pylori infection is potential class I carcinogen in initial step of gastric carcinogenesis, only between 1% and 3% of patient with H. pylori infection develop gastric cancer. In addition, many current studies have revealed significant change in microbiome profile of patient with H. pylori-negative gastric cancers. Many studies have revealed significant change in microbiome profile of patient with H. pylori-negative gastric cancers. Therefore, the investigators have hypothesized that unidentified non-H. pylori bacteria play a role in gastric cancer development. * However, most of current studies of gastric microbiota in patients with gastric cancer have been conducted in Eastern Asia, particularly in China and Korea, there is still no published data from Thailand. Moreover, all previous studies have used gastric tissue biopsy method. There has been no analysis of gastric microbiota using the mucosal brushing technique, despite its favoring benefit in microbiota study * This study is pilot phase, cross-sectional and case-control study that aims to evaluate microbiota profile in patients with gastric cancer, compared to those without gastric cancer by using mucosal brush sampling. * According to previous studies, H. pylori had significant impact on the composition of gastric microbiota. Presence of H. pylori could affect the result of the study. Therefore pre-specified subgroup analysis of H.pylori infection and non-H.pylori infection will be perform. * Study protocol include * Age, gender, BMI, smoking history, history of PPI use within 3 months, history of infection within 2 weeks, history of antibiotic use within 3months, history of probiotic use within 3months, history of intraabdominal surgery, history of dietary supplement and herbal use will be recorded in case record form. * After consent, standard EGD will be performed. * The gastric mucosa using mucosal brushing with sterile sheathed brush, gastric mucosal biopsy by standard forceps biopsy and rapid urease test for evaluate H.pylori status will be done respectively. * The gastric mucosal specimen will be keep in sterile tube and immediate keep in freezing at -80C (allow room temperature \<2 hr) for 16sRNA sequencing analysis.
