title: Prognostic significance of histological type in gastric carcinoma with invasion confined to the stomach wall.
abstract: Survival was determined after resection for the two main histological types of gastric carcinoma, intestinal (n = 223) and diffuse (n = 170), in 393 patients with pT1 or pT2 tumours. Lymph node metastases were present in 94 patients. The 10-year survival rate was significantly lower for patients with intestinal-type than for those with diffuse-type carcinoma (72 versus 91 per cent, P < 0.005). In patients without nodal involvement, the 10-year survival rate was still lower for those with intestinal-type cancer (70 versus 94 per cent, P < 0.01). Recurrence of carcinoma was more often by haematogenous dissemination in patients with intestinal-type cancer. Although the results of resection for pT1 or pT2 gastric carcinoma can be acceptable, the introduction of adjuvant therapy based on histological findings may be necessary for patients with the intestinal type of cancer to prevent haematogenous spread of carcinoma to the liver.
