title: [Efficacy of combined splenectomy in proximal gastric cancer with No.10 lymph node metastasis].
abstract: OBJECTIVE
  To explore the impact on prognosis of D(2) lymphadenectomy combined with splenectomy in patients of advanced proximal gastric cancer with No.10 lymph node metastasis.
  
  
  METHODS
  Clinical data of 216 patients of advanced proximal gastric cancer with No.10 lymph node metastasis undergone D(2) curative resection in our hospital from January 1980 to December 2002 were analyzed retrospectively. Among them, 73 underwent simultaneous splenectomy (splenectomy group), while 143 without splenectomy (spleen-preserving group). The 5-year survival rate, the mean numbers of dissected No.10 lymph nodes and metastatic No.10 lymph nodes, the complication morbidity and mortality were compared between the two groups.
  
  
  RESULTS
  The 5-year survival rates of splenectomy group and spleen-preserving group were 30.0% and 19.7% respectively, whose difference was significant(P<0.05). The mean numbers of dissected No.10 lymph nodes and metastatic No.10 lymph nodes in splenectomy group were significantly greater than those in spleen-preserving group(P<0.05). Splenectomy, invasion depth and gastrectomy type were independent prognostic factors. The survival rates of T(3) patients in splenectomy group and spleen-preserving group were 38.7% and 18.9% respectively, whose difference was significant (P<0.05). The survival rates of patients undergone total gastrectomy in splenectomy group and spleen-preserving group were 33.4% and 20.7% respectively, whose difference was significant (P<0.05). The complication morbidity and mortality in splenectomy group were 24.7% and 4.1%, while in spleen-preserving group were 17.5% and 3.5% respectively, whose differences were not significant(P>0.05).
  
  
  CONCLUSIONS
  Splenectomy is benefit for No.10 lymph node dissection in patients with advanced proximal gastric cancer. To improve the prognosis, total gastrectomy combined with splenectomy should be recommended for patients of T(3) proximal gastric cancer with No.10 lymph node metastasis. Simultaneous splenectomy dose not increase the complication morbidity and mortality.
