Additional Information

Official title Randomized Controlled Trial to Evaluate Splenectomy in Total Gastrectomy for Proximal Gastric Carcinoma: JCOG0110
Description European clinical trials of gastrectomy showed that splenectomy is an important risk factor for post-operative morbidity and mortality. Retrospective comparisons suggested that splenectomy is associated with poor long term survival. However, Japanese studies revealed that 20 - 30 % of patients with non-early carcinoma in the proximal stomach have nodal metastasis in the splenic hilum and therefore, pancreas-preserving splenectomy is part of the standard operation in specialized centers where splenectomy is not considered a risk factor for operative mortality. There have been no prospective randomized trials to evaluate the survival benefit of splenectomy in total gastrectomy for proximal gastric cancer. Comparison: Total gastrectomy with pancreas-preserving splenectomy versus total gastrectomy without splenectomy
