The purpose of this study is to find out more about differences of the quality of life in patients undergoing total gastrectomy or proximal gastrectomy for adenocarcinoma of esophagogastric junction. To find a better reconstruction for patients who received total gastrectomy.

Overall, the incidence of stomach cancer worldwide is declining with geographical variation. However, an increase in the incidence rate of adenocarcinoma of esophagogastric junction, called cardia or AEG has been observed in recent years. AEG may represent a specific histopathological and biologic entity. In the treatment AEG there is argument over whether proximal gastractomy(PG) or total gastractomy (TG) should be done. The quality of life (QOL) of the patients following TG or PG arouses people's attention. The purpose of this study was to evaluate differences of the quality of life in patients undergoing total gastrectomy or proximal gastrectomy for adenocarcinoma of esophagogastric junction.

Inclusion Criteria:

• • Pathologically confirmed gastric malignant tumor at FUSCC (biopsy may be performed at other institutions but slides must be confirmed at FUSCC, as is routine care at our institution), and the patients be assessed can achieve R0 radical dissection through total gastrectomy or proximal gastrectomy by three specialists.
