title: Efficacy of extended lymphadenectomy in the noncurative gastrectomy for advanced gastric cancer.
abstract: OBJECTIVE
  We retrospectively analyzed clinicopathologic data on 83 patients with advanced gastric cancer who underwent noncurative gastrectomy, with respect to the relation between the extent of lymphadenectomy and survival benefit.
  
  
  METHODS
  These 83 patients were divided into 44 patients with limited or simple lymph node dissection (D0 in 14 and D1 in 30: Group A) and 39 patients with extended lymph node dissection (D2: Group B).
  
  
  RESULTS
  The 1-year survival rate in Group B (82.1%) was significantly higher than in Group A (49.0%). However, the 3-year and 5-year survival rates did not significantly differ between Group A versus Group B, 39.7% versus 25.7% and 39.7% versus 20.5%, respectively. Median survival time after surgery with and without distant metastasis in Group B (21.5 months) was longer than in Group A (16.4 months), although not significant.
  
  
  CONCLUSIONS
  While gastrectomy with extended lymphadenectomy did not contribute to improve long-term survival in patients with noncurable advanced gastric cancer, the utility of extended lymph node dissections may be relevant to improved locoregional control, at least in the prognosis within 1 year after surgery. Not only extended lymphadenectomy but also aggressive chemotherapy may be needed to improve the long-term survival for such patients.
