Gastric Carcinoma, Gastric Precancerous Lesions, Gastritis Chronic, Intestinal Metaplasia
Conditions
Brief summary
The objective of this clinical trial is to explore the correlation between the level of microplastic exposure and the risk of gastric mucosal carcinogenesis, and to evaluate the strength of its effect as an independent risk factor. The main questions it aims to answer include: Does the level of microplastic exposure increase the risk of gastric mucosal carcinogenesis? Can the correlation between the level of microplastic exposure and gastric mucosal carcinogenesis, as well as the sources of high - risk microplastic exposure, be explored through a questionnaire on external microplastic exposure? Researchers will complete a design structured questionnaire and ask participants to fill it out carefully and truthfully to determine whether the level of microplastic exposure increases the risk of gastric mucosal carcinogenesis.
Detailed description
The study will categorize participants into three groups based on endoscopic and/or histopathological findings: chronic non-atrophic gastritis, precancerous lesions, and gastric cancer. Basic demographic information, \*Helicobacter pylori\* infection status, and plastic exposure assessment scores will be recorded for each group.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Correlation between external exposure levels of microplastics and three pathological stages of gastric mucosal carcinogenesis | 9 months | The investigators evaluated the correlation between external exposure to microplastics and the three pathological stages of gastric mucosal carcinogenesis based on the patients' final diagnosis results and the completed questionnaires they filled out. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Analysis of sources of high - risk microplastic exposure | 9 months | Analyze the sources of high-risk microplastic exposure by comparing the scores of each item in the questionnaires of the three groups of participants. |
| Synergistic toxicity of microplastics and Helicobacter pylori | 9 months | Analyze whether microplastics synergistically promote gastric mucosal injury and increase the risk of canceration with Helicobacter pylori through interaction. |
