New lymph node classification systems outperform AJCC in predicting gastric cancer survival

Log odds of positive lymph nodes (lodds) and positive lymph node ratio (lnr) demonstrate superior predictive capabilities for survival in gastric signet ring cell carcinoma (gsrc) patients compared to the traditional AJCC n-category. Multivariate analysis reveals both lodds and lnr as significant prognostic factors, with improved sensitivity and specificity in predicting outcomes at 1, 3, and 5 years. Their robust performance suggests they could replace the n-category for better survival risk assessment in clinical applications.
