Current diagnostic methods, including imaging and histopathology, have limited sensitivity and specificity. This study aims to develop and evaluate machine learning (ML) models that predict LNM in NSCLC using single-nucleotide polymorphism (SNP) data from The Cancer Genome Atlas.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>METHODS<\/jats:title>\n            <jats:p>A cohort of 542 patients with NSCLC with comprehensive SNP data were analyzed. After preprocessing, feature selection was performed using chi-square tests to identify SNPs significantly associated with LNM. Twelve ML models, including Logistic Regression, Naive Bayes, and Support Vector Machines, were trained and evaluated using bootstrapped data sets. Model performance was assessed using metrics such as accuracy, area under the receiver operating characteristic curve (AUC), and F1 score. Shapley additive explanations values were used for feature interpretability, and survival analysis was conducted to assess clinical outcomes.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>RESULTS<\/jats:title>\n            <jats:p>\n              Naive Bayes and Logistic Regression models achieved the highest predictive performance, with median AUCs of 0.93 and 0.91, respectively. Key SNPs, including mutations in\n              <jats:italic toggle=\"yes\">TANC2<\/jats:italic>\n              ,\n              <jats:italic toggle=\"yes\">KCNT2<\/jats:italic>\n              , and\n              <jats:italic toggle=\"yes\">CENPF<\/jats:italic>\n              , were consistently identified as predictive features. Survival analysis demonstrated significant differences in outcomes on the basis of model-predicted LNM status (log-rank\n              <jats:italic toggle=\"yes\">P<\/jats:italic>\n              = .0268). Feature selection improved model accuracy and robustness, highlighting the biological relevance of selected SNPs.\n            <\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>CONCLUSION<\/jats:title>\n            <jats:p>ML models leveraging primary tumor SNP data can enhance LNM prediction in NSCLC, outperforming traditional diagnostic methods.
