Core Tip
Core Tip: This large-scale, retrospective cohort study compared prognostic outcomes of gastric adenocarcinoma and gastric signet-ring cell carcinoma (GSRCC) and revealed heterogeneous survival risks. While no overall survival difference was observed, GSRCC demonstrated significantly worse prognosis in age ≥ 60 years, size ≥ 4 cm, and poor differentiation. A new nomogram incorporating seven clinicopathological variables demonstrated greater accuracy than traditional tumor node metastasis staging in predicting 1-, 3-, and 5-year overall survival (P < 0.001). Key innovations include the application of least absolute shrinkage and selection operator regression to address multicollinearity and propensity score matching to minimize baseline bias. Integration of the model into clinical workflows could enable real-time risk stratification and guide personalized therapy for resectable gastric cancer.
