Stratification analysis of the optimal model based on 3 independent clinical factors in the training set.
| Independent clinical factors | 3-year AUC | 5-year AUC |
|---|---|---|
| Molecular type | ||
| MSS/TP53+ | 0.860 | 0.816 |
| MSS/TP53− | 0.843 | 0.800 |
| MSI | 0.677 | 0.717 |
| MSS/EMT | 0.782 | 0.881 |
| Recurrent status | ||
| Yes | 0.664 | 0.748 |
| No | 0.812 | 0.730 |
| Operation type | ||
| TG | 0.765 | 0.804 |
| STG | 0.770 | 0.684 |
AUC – area under the curve; MSS – microsatellite stable; TP53+ – tumor protein 53 active; TP53− – tumor protein 53 inactive; MSI – microsatellite instability; EMT – epithelial-mesenchymal transition; TG – total gastrectomy; STG – subtotal gastrectomy.
