OBJECTIVE: To investigate the rule of lymph-node @entity3 in @entity356 and the rational extent of lymph node dissection. METHODS: Clinicopathological data of 77 @entity1 with @entity356 were reviewed and the relationship between extent of lymph-node dissection and prognosis was analyzed retrospectively. RESULTS: (1) The lymph node @entity3 rates were 64.9% for N(1), 14.3% for N(2) and 10.4% for N(3). (2) No lymph node @entity3 was detected in T(1) stage @entity5 and maximum diameter of less than 2.0 cm. The lymph node @entity3 rates were 20% for T(2), 68.2% for T(3) and 82.8% for T(4) respectively. (3) Lymph node No.1, 3, 2 were often involved in the @entity3 of lymph node group 1, and No.7, 8, 10, 9 in Group 2. In lymph node group 3, lymph node @entity3 rates were 6.5% for No.5, 1.3% for No.6, 1.3% for No.16 and 2.6% for No.107-110. (4) The five-year survival rates were 36.5% for D(3), 31.3% for D(2), and 22.7% for D(1) lymphadenectomy respectively. The survival rates of @entity1 undergone D(2) and D(3) lymphadenectomy were significantly higher than that undergone D(1) dissection (P<0.05). CONCLUSION: D(2) or more than D(2) lymphadenectomy associated with enlargement of esophageal hiatus via laparotomy, lower partial esophagectomy and total gastrectomy is able to achieve surgical resectability and improve the survival rate of @entity356 @entity1 .
