Of these,26 patients(9.4%) had HDLN metastasis. First,we investigated the clinicopathological characteristics,their perioperative clinical outcomes,such as postoperative complications,and prognostic outcomes between patients with and without HDLN metastasis. Second,we detected the prognostic factors,particularly in patients with HDLN metastasis. Third,we assessed the therapeutic value of HDLN dissection to determine its optimal indication.RESULTS: The five-year overall survival rate of the patients with HDLN metastasis was 29%. Univariate and multivariate logistic regression analyses revealed that the tumour location(the middle or lower stomach [P = 0.005,OR = 5.88(95%CI: 1.61-38.1)] and p T category [T3 or T4,P = 0.017,OR = 4.45(95%CI: 1.28-21.3)] were independent risk factors for HDLNmetastasis. Cox proportional hazard analysis identified p N3 as an independent poor prognostic factor in the patients with HDLN metastasis [P = 0.021,HR = 5.17(95%CI: 1.8-292)]. For patients who underwent radical HDLN dissection,HDLN metastasis was a prognostic indicator in p N3 gastric cancer(P < 0.0001),but not p N1-2(P = 0.602). Furthermore,the index of therapeutic value of HDLN dissection for gastric cancer in the middle or lower stomach and the upper stomach was 3.4 and 0.0,respectively.CONCLUSION: We suggest that HDLN dissection should be indicated for p N1 or p N2 gastric cancers located at the middle or lower stomach.展开更多
