Enhanced Gastric Cancer Staging Using New N Classification System

This study developed and validated a new lymph nodal staging system for pt3-4n0-2m0 gastric cancer patients. The new classification, based on examined lymph nodes and lymph node ratio, outperformed the current system in prognostic prediction accuracy. The improved staging method emerged as an independent prognostic indicator, providing enhanced survival analysis for patients. Surgeons are encouraged to consider these factors for better postoperative prognosis assessment.
