A novel contour-like model enhances risk stratification for gastric cancer patients post-neoadjuvant therapy, improving surgical decision-making.

• The con-yptn model shows an AUC of 0.853 for predicting overall prognosis, significantly outperforming existing staging systems.
• High-risk patients identified by this model have notably worse survival outcomes compared to low-risk individuals.

Utilizing this model can refine patient selection for postoperative strategies, enhancing overall outcomes.
