BACKGROUND: To understand the efficacy of gastrectomy combined with the resection of other organs and to refine the indications for this type of surgery, the records of 156 patients with carcinoma of the stomach directly invading adjacent organs or structures (T4 gastric carcinoma) were analyzed retrospectively. METHODS: The patients were divided into three groups, as follows: in group A, curative resection was performed by the combined resection of invaded organs or structures; in group B, although combined resection was performed, curative resection could not be performed because of the extent of lymph node metastasis, liver metastasis, and/or peritoneal metastasis; in group C, combined resection was not performed. RESULTS: In patients with peritoneal or liver metastasis, there was no significant difference in prognosis among the three groups. In patients without peritoneal and liver metastasis, the prognosis of group A was significantly better than that of group B or group C, irrespective of the extent of lymph node metastasis or the number of invaded organs. In these group A patients, the 5-year survival rates of those with localized tumors and no lymph node metastasis, those with localized tumors and lymph node metastasis, those with infiltrating tumors and no lymph node metastasis, and those with infiltrating tumors and lymph node metastasis were 100%, 56.2%, 57.1%, and 13.6%, respectively. CONCLUSIONS: Combined resection of involved organs should be carried out with curative intent in patients with localized gastric cancer or infiltrating gastric cancer without lymph node metastasis.
