Objective To analyze the correlation of both the distance from lower edge of gastric cancer to pylorus and the Borrmann classification with metastasis of lymph node groups (LNG) 5 (suprapyloric) and 6 (infrapyloric). Methods There were 374 cases with gastric cancer including the group with LNG 5 and 6 metastasis and the group without LNG 5 and 6 metastasis. The critical ditance from lower edge of gastric cancer to pylorus which predicted LNG 5 and 6 metastasis was analyzed combined with the risk factors for LNG 5 and 6 metastasis. LNG 5 and 6 metastasis in patients with gastric cancer stage T1 and T2 (Borrmann Ⅱ) was analyzed. Results LNG 5 and 6 metastasis in patients with gastric cancer could be predicted using distance from lower edge of tumor to pylorus with the critical distance 3.75 cm. The rate of lymph node metastasis was 11.1% when the distance from lower edge to pylorus was longer than 3.75 cm. The independent risk factors for LNG 5 and 6 metastasis were gotten including the distance from the lower edge of tumor to pylorus, Borrmann classification, extent of differentiation of cancer, depth of infiltration, and gastric cancer stage. There was no statistical difference in metastasis of LNG 5 and 6 between stage T1 and stage T2 (Borrmann Ⅱ) of gastric cancer when the distance from lower edge of tumor to pylorus was longer than 3.75 cm (P>0.05). Conclusions There was no difference in LNG 5 and 6 metastasis between T1 and T2 (Borrmann Ⅱ) gastric cancer, when the distance from lower edge of tumor to pylorus was longer than 3.75 cm,
