[A comparative study of therapeutic effects of total versus proximal subtotal gastrectomy in adenocarcinoma of the gastric cardia].

485 patients with adenocarcinoma of the gastric cardia operated in our hospital. 283 cases were treated with total gastrectomy, and 202 cases were treated with proximal subtotal gastrectomy. The age, sex, clinical stage, size of tumour, radicality of surgical resection, lymph node involvement, tumour depth penetration and histological type had no significant difference in the two groups. Analysis of survival rates failed to demonstrate any significant difference between the two types of surgical operation for TNM stage I and II. Total gastrectomy resulted in significantly higher survival rate than proximal subtotal gastrectomy for stage III. The 3- and 5-year survival rate of TNM stage III patients increased by 14.6% and 15.1%, respectively (P < 0.05). Extended total gastrectomy was usually applied for stage IV patients without distant metastasis. If the neoplasm had spread beyond the confines of extended total gastrectomy, in order to eliminate obstruction or bleeding, palliative proximal subtotal gastrectomy or total gastrectomy should be considered.
