Out of 1041 patients who underwent surgery for gastric cancer between 1968 and 1987, 120 patients suffered from early gastric cancer (11.5%). Until 1976, early gastric cancer was treated along the lines of surgical treatment of benign ulcer disease, i.e. by partial 2/3-gastric resection without lymphadenectomy, even though malignancy had been confirmed preoperatively in all cases. Since 1979 oncological criterias (subtotal or total gastrectomy with lymphadenectomy) have gained importance in treating early gastric carcinoma. In the case of mucosal carcinoma, the extent of surgical intervention does not have any influence on the 10-year survival rate. In treating submucosal carcinoma 10-year survival rates of 72.9 (+/- 7.2%) can only be achieved by performing total gastrectomy and lymphadenectomy whereas the 10-year survival rate after performing partial 2/3-gastric resection alone (p = 0.01) is only 17.6 (+/- 9.2%). Since mucosal and submucosal carcinoma cannot accurately be differentiated preoperatively, surgical intervention must be carried out in an oncological sense. The fact that 2/3 partial gastric resection does not generally ensure adequate therapy implies that local procedures are even less sufficient. Even in cases of mucosal infiltration only, local procedures such as laser therapy and local excision of the tumour cannot be considered being a curative approach, since hereby the probability of lymph node metastases (4%) is not taken into account.
