Background:

Gastric cancer is a complex disease influenced by genetic and clinical factors.
Accurate preoperative staging is crucial for effective treatment planning.
Existing methods may not fully capture the multifactorial nature of gastric cancer.

Purpose of the Study:

To develop and evaluate an artificial neural network (ANN) model for predicting gastric cancer tumor staging.
To identify key clinicopathological and genetic factors influencing gastric cancer staging.
To assess the utility of genetic polymorphisms in preoperative cancer staging.

Main Methods:

Retrospective analysis of clinical and pathological data from 121 primary gastric cancer patients.
Evaluation of genetic polymorphisms in candidate genes.

Application of an ANN model to predict tumor stage and determine factor importance.

Main Results:

The ANN model achieved an accuracy of 81.82% using the Quick training method.
Significant factors for tumor staging included patient age and polymorphisms in p21, IL-1, IL-4, and p53 genes.
The study identified the relative impact of various genetic and clinical factors.

Conclusions:

ANN analysis of genetic polymorphisms and clinicopathological data is a promising approach for gastric cancer staging.
This strategy can pinpoint crucial genetic, clinical, and pathological predictors.
The findings support the development of a prognostic staging system for individualized patient care.
