Association Between Microplastic Exposure and the Pathological Progression of Gastric Carcinogenesis

April 25, 2026 updated by: Yongquan Shi

Association of Microplastic Exposure With Pathological Stages of Gastric Mucosal Carcinogenesis: A Cross-Sectional Study

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.

Study Overview

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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Correlation between external exposure levels of microplastics and three pathological stages of gastric mucosal carcinogenesis
Time Frame: 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.
9 months

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Analysis of sources of high - risk microplastic exposure
Time Frame: 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.
9 months
Synergistic toxicity of microplastics and Helicobacter pylori
Time Frame: 9 months
Analyze whether microplastics synergistically promote gastric mucosal injury and increase the risk of canceration with Helicobacter pylori through interaction.
9 months
