✦ Synopsis

We performed univariate and multivariate analyses of possible prognostic factors related to postoperative clinical course of patients with advanced gastric cancer. Noncurative resection was done for 119 patients with hepatic metastasis, peritoneal seeding, extensive lymph node metastasis, or direct invasion to adjacent organs, either alone or in various combinations.

In the univariate analysis, 6 of 17 items such as peritoneal seeding, lymphatic invasion, vascular invasion, mode of invasion, extent of lymphadenectomy , and width of serosal invasion significantly correlated to the prognosis. The multivariate analysis indicated that three inherent pathologic factors, mode of invasion, lymph node metastasis, and hepatic metastasis, and one treatment factor, extent of lymphadenectomy , were significant variables predictive of the prognosis and that the prognosis was expected to be very poor in cases of infiltrative type, nodal involvement to tertiary nodes, presence of hepatic metastasis, and lymphadenectomy less than R3. Prognosis in terms of the extent of lymphadenectomy shows that extensive lymphadenectomy (R3) proved to be significantly effective in prolonging survival time, even after noncurative gastrectomy. We recommend extensive lymphadenectomy to prolong survival time for such patients.
