摘要: Abstract Background Most nomograms for Gastric Cancer (GC) were developed to predict overall survival (OS) after curative resection. The Italian Research Group (GIRCG) prognostic scoring system (PSS) was designed the recurrence risk treatment based on pathologic tumor stage and performed (D1–D2/D3 lymphadenectomy). This study carried out externally validate GIRCG's PSS. Patients methods Adopting same criteria used by GIRCG build PSS, 185 patients with GC operated intention selected. median follow-up period 77.8 months (1.93–150.8) all 102.5 (60.9–150.8) free of disease. NRI (net reclassification improvement) calculated estimate improvement in using PSS place TNM system. Results occurred 70 (37.8%) patients. mean time 22.2 (range 1.9–98.1) months. For recurrence, gain proportion 0.257 (p Conclusion which predicts likelihood radical surgical GC, is more accurate than mainly high-risk Yet, does not have effectiveness low-risk patients, overestimating chance occurs even disease-free
