Lymph Node Yield and Lymph Node Ratio for Prognosis of Long-Term Survival in Gastric Carcinoma

Abstract

Long-term survival of patients with gastric cancer is still poor. Adequate lymphadenectomy is one of the key factors that influence the long-term results of surgery. However, there is still no complete knowledge about factors influencing the lymph node yield. In our study, we analyzed these factors. For many years, the TNM system has allowed estimating long-term survival, but there are many indications that the system, along with UICC/AJCC, should be enriched with additional elements. Lymph node ratio (LNR) seems to be such an element. In this study, we performed a comprehensive analysis of the effect of LNR on long-term survival in patients with gastric cancer.
