摘　　要：Objective： To investigate the recurrent patterns and factors involved in node-negative advanced gastric cancer after curative resection. Patients and Methods： Clinicopathological characteristics and prognostic outcomes of 310 patients who had lymph node-negative advanced gastric adenocarcinoma and received curative resection between 2002 and 2006 were retrospectively evaluated. Results： Among the 300 patients, 15 （5.0%） had locoregional recurrence, 5 （1.7%） had lymph node recurrence, 27 （9.0%） had peritoneal seeding recurrence, and 21 （7.0%） had hematogenous metastasis. Using multivariate analysis, we found that the maximum tumor diameter （P=0.014）, histological type （P=0.001） and Borrmann type （P=0.033） were independent factors predicting the locoregional recurrence. Lymph node recurrence was significantly affected by lymph node dissection （P=0.029） and lymphovascular invasion （P=0.004）. Clinicopathological factors predicting the peritoneal seeding recurrence were the depth of invasion （P=0.001） and Borrmann type （P=0.002）. In addition, lymphovascular invasion （P=0.013） and histological type （P=0.001） were significantly associated with hematogenous metastasis. Conclusion： Node-negative advanced gastric cancer has a high amount of peritoneal seeding and hematogenous metastasis.Objective： To investigate the recurrent patterns and factors involved in node-negative advanced gastric cancer after curative resection.
