Objective:To study the regularity of advancing gastric cancer (AGC) lymph nodes metastasis,explain the clinical rationalization of undertaking R2 and R3 operations for removing AGC and the necessity of cleanup of lymph nodes in Ⅱ and Ⅲ stations. Methods:35 cases were undergone R2 and Rj operations. It was documented pathologically that there were 20 cases with middle-differentiated adenoma,9 with poor-differentiated adenoma,6 with mucus adenoma. Among them there were 35 cases with lymph node metastasis n1 ( + ), 26 cases with n2( + ), 3 with 113 ( + ). After operation the patients got well. 10 patients were followed-up for 5 years. The results show that 3 cases were survival without cancers and 6 died of cancer metastasis. Another 10 patients followed-up for 3 years were all well without cancers.9 cases followed-up for one year all existed well. Conclusion: R2 and R3 operations may cure AGC in some degree and increase markedly the survival rate. This kind of operation is feasible in clinic.
