Patients were divided into training and internal test sets at a ratio of 7:3 using stratified sampling. Logistic regression analyses were performed to identify factors associated with distant metastasis, and six machine learning algorithms were developed and compared. SMOTE was applied only to the training set to address class imbalance. Multivariate logistic regression identified sentinel lymph node biopsy as an independent protective factor, whereas higher N stage and lower median household income were independent risk factors. Among the evaluated models, LightGBM showed relatively balanced overall performance and was selected as the optimal model. SHAP analysis identified N stage, sentinel lymph node biopsy record, and median household income as the most important predictors.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The LightGBM model demonstrated moderate predictive performance for distant metastasis risk stratification in patients with AM.
