A total of 77 patients were diagnosed with stage IV distal gastric cancer, and lymph node metastases were found in 40 patients. Of these, 20 patients had No. 7 lymph node involvement, while the other 20 cases did not have lymphatic invasion. The 5-year overall survival rate of patients was 7.2%, with No. 7 lymph node metastasis was 5%, and without No. 7 lymph node metastasis was 12%, which were not statistically significant (P=0.852).
