Gastric cancer is one of the most common malignant tumors in the digestive tract and poses a serious threat to human health.Early warning and diagnosis can increase the 5-year survival rate by more than 60%.In recent years,machine learning methods have achieved rich results in predicting the precancerous state of gastric cancer.This article first discussed the significant features of the precancerous state of gastric cancer from the aspects of endoscopic images,biochemical markers,gene expression,and traditional Chinese medicine syndromes,and analyzed the advantages and disadvantages of traditional machine learning methods,deep learning methods and various fusion methods by combining the research results of the precancerous state of gastric cancer predicted by machine learning methods.It proposed three suggestions for carrying out multi-center,large-sample cohort studies and building shared data platforms,realizing multi-modal data fusion and enhancing the interpretability of the model,providing methodological references for the“early diagnosis and treatment”of gastric cancer.
