Abstract
We report the late results of resection in 281 patients with gastric carcinoma extending to adjacent organs. In 92 without incurable factors (peritoneal dissemination, liver metastasis and widespread nodal involvement) the 5-year survival rate was 36.7 per cent in those treated by gastrectomy and complete removal of the invaded organ. This value is significantly higher than the 17.4 per cent recorded in those undergoing gastrectomy alone or with incomplete removal of the invaded organs (P < 0.05). In 189 patients with incurable factors, the 5-year survival rates were 5.4 and 2.8 per cent respectively in cases of complete and incomplete excisions. This tendency was similar in patients with a single invaded organ and also in those with plural organ involvement. In potentially curable patients treated by complete excision, the probability of long-term survival was statistically better than that following incomplete excision only when the pancreas was involved (P <0.05). We recommend complete excision of invaded organs, irrespective of the number or site of organs involved, provided that there is no evidence of incurable factors.
