A total of 226 patients were diagnosed with stage III distal gastric cancer, and lymph node metastases were found in 165 patients. Among patients with lymph node metastases, 79 cases had No. 7 lymph node metastasis, while 86 cases did not have No. 7 lymph node metastasis. The 5-year overall survival rate of patients with lymph node involvement was 34.4%, with No. 7 lymph node metastasis was 28.4%, and without No. 7 lymph node metastasis was 39.1%, which were not statistically significant according to Kaplan-Meier analysis (P=0.542).
