Methods： 217 patients with GEJ who underwent surgical resection were retrospectively analyzed. The extent of lymphadenectomy was divided into 5 types （DO to D4） and the curability of operation was graded as A, B and C. Results： The patients had been treated as follows： 186 with proximal gastrectomy, 31 with total gastrectomy, 97 with a combined-visceral resection. The patients who underwent D1, D2 and D3 lymphadenectomy were respectively 158, 58 and 1. The patients who were performed with resection of grade A, B and C were 53, 107 and 57 respectively. All patients were performed with a lymphadenectomy and well registered. The lymph node metastasis occurred in 157 cases （72.4%）. The lymph node metastasis rate in the group 1, 2, 3, 4, 7, 9, 12 and 110 as well as in the pulmonary ligament group were higher than other groups. 2868 lymph nodes were removed, in which 655 （22.8%） demonstrated the existence of metastasis. The total lymph node metastatic degree in these groups was higher compared to the other groups. Conclusion： The survival rate in the D1 lymphadenectomy and D2 is similar for all patients, and there may be some differences in the 2nd and 3rd years for the DI lymphadenectomy and D2 in the stage-Ⅲb patients. The survival rate of D2 lymphadenectomy in stage Ⅲb is better than D1 and that of D2 lymphadenectomy is superior to D1 in stage-Ⅳ patients. The survival rate of grade A and B operation is much better than grade C, and the survival rate of grade A is also higher than B.展开更多
