title: [Subclassification of stage IV gastric cancer].
abstract: We studied the prognosis of 185 stage IV gastric cancer cases. The univariate analysis and multivariate analysis suggested that liver metastases (H) and peritoneal disseminations (P) were prognostic factors, the number of factors may be it, and lymph nodes metastases (N) and invasion to the other organs (T) were not it. Based on these findings, we proposed a subclassification of stage IV: IVa [T1-3N3-or T4N2] and IVb [the others]. The survival rates for IVa significantly exceeded those of IVb and did not differ from those of 25 stage IIIb gastric cancer cases.
