Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Chronic atrophic gastritis (CAG) is acknowledged as the precancerous stage of gastric cancer (GC). The present study aims to explore Traditional Chinese Medicine (TCM) syndrome features in different stages of CAG malignant transformation respectively. The proposed study is a cross-sectional study based participant survey conducted in 4 hospitals in Beijing, China. After obtaining informed consent, a total of 2000 study patients will be recruited on-site in hospitals.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

CAG is acknowledged as the precancerous stage GC. Active treatment of CAG is vital in arresting malignant transformation. Traditional Chinese medicine (TCM) has been widely used in treating CAG and preventing GC in China. To date, few study has been conducted to assess the syndrome features of different stages of CAG malignant transformation combining TCM indicators.

The present study aims to explore TCM syndrome features in different stages of CAG malignant transformation. The proposed study is a registry study based participant survey conducted in 4 hospitals in Beijing, China. After obtaining informed consent, a total of 2000 eligible study patients will berecruited on-site in hospitals.

Comparative analysis of prevalence of presenting TCM features is conducted using frequency analysis and chi-squared tests, and expressed with composition ratios. Exploratory factor analysis,correspondence analysis, association rule analysis, hierarchical clustering analysis, and complex system entropy clustering analysis will be performed respectively for validating features of syndrome in different stages of CAG malignant transformation.

Previous reports on TCM syndrome features for CAG exist, but no studies have been undertaken base on large-sampled study design and detailed analysis in different stages of CAG malignant transformation respectively.

The outcome of our study has the potential to clerify core TCM pathogenesis of CAG, facilitate early intervention, and promote optimization of treatment strategies of CAG malignant transformation by TCM.
