Lymph node metastasis of gastric cancer: comparison of Union International Contra Cancer and Japanese systems

Background:  The pN classification of gastric cancer (GC) in the Japanese system (Japanese Gastric Cancer Association; JGCA) is based on the site and distance of metastatic nodes from the primary tumour. Union International Contra Cancer (UICC) has recently proposed a classification system based on...

Description
Summary:Background:  The pN classification of gastric cancer (GC) in the Japanese system (Japanese Gastric Cancer Association; JGCA) is based on the site and distance of metastatic nodes from the primary tumour. Union International Contra Cancer (UICC) has recently proposed a classification system based on the number of nodes involved (TNM‐1997). The aim of the present study is to assess which classification system is more suitable for providing a prognosis in advanced GC with lymph node metastasis. Methods:  A total of 224 patients who underwent curative gastrectomy (R0: UICC−TNM and Resection A and B: JGCA) and D2 lymphadenectomy between 1990 and 1999, and diagnosed as pT2, pT3 and pT4 GC were enrolled. Patients were followed until the end of 2002. The disease‐free survival rates of patients were compared between the two‐stage systems (UICC−TNM and JGCA). Results:  Using the JGCA system, there was a significant difference between the two survival curves (pN0 and pN1, P = 0.025; pN1 and pN2, P
