title: [Evaluation of splenectomy in total gastrectomy for gastric cancer].
abstract: It has been well accepted that extensive prophylactic lymphadenectomy is certainly effective for elevating cure rate after gastric cancer surgery, however, regarding to the prophylactic splenectomy the arguments are controversial. We studied the value of splenectomy in total gastrectomy for gastric cancer by examining the late survival rates, the accuracy of intraoperative judgement of splenic hilar lymph node metastasis and postoperative changes of serum immunosuppressive factors. In curatively resected stage III cases without splenic hilar lymph node metastasis, the nonsplenectomized group showed a significant better late survival rate than the splenectomized group, 5-year survival rate being 59.9% in the former and 30.8% in the latter. In cases with splenic hilar lymph node metastases, 2 of 9 splenectomized patients survived more than 10 years. In cases of noncuratively resection, splenectomy did not enhance the survival rate. Although further clinical randomized study is needed to draw a definitive conclusion, we had better take a splenic reserve operation for the patients without splenic hilar lymph node metastasis. On the other hand, splenectomy should be performed in cases with splenic hilar lymph node metastases.
