Objective To evaluate the status of lymph node metastasis and reasonable procedure in gastric cancer. Methods The incidence of metastases from gastric cancer to various regional lymph node stations was studied in 1 505 patients with gastric cancer. The patients underwent surgical resection from January 1995 to December 2004.Results Lymph node metastasis were observed in 928 of 1 505 cases (61.7%). Lymph node metastasis frequency was found in groups No.1 （32.9%），No.3 （28.7%）， No.2 （20.4%）， and No.7 （18.6%） at upper third stomach cancer；in groups No.3 （32.5%）， No.4 （24.7%）， No.7 （20.6%）， and No.1 （17.3%） at middle third stomach cancer； in groups No.6 （33.7%）， No.3 （31.3%）， No.4 （25.6%）， and No.7 （21.5%） at lower third stomach cancer. Conclusions Distribution of metastatic lymph node is clearly related to the location of the tumor. Anatomical extent of lymph node metastases in gastric cancer provid surgical guidance for surgeons.
