A clinical study on intraperitoneal invasive recurrent gastric cancer (REC-G, 23 cases) and colorectal cancer (REC-C, 18 cases) was performed. In P₀, P₁ and P₂ cases of REC-C, the ratio of discharge was 100% in curative cases (CUR) and palliative cases (PAL) and 40% in unresected cases (UNR) and the mean survinal was 731, 468 and 174 days. In P₀ and P₁ cases of REC-C, the ratio of discharge was 100% in CUR, 80% in PAL and 67% in UNR and the mean survival was 1087, 443 and 306 days. The ratio of discharge and prognosis was better in CUR and PAL in both groups. In P₃ cases of REC-G, there was no CUR cases and the ratio of discharge was 67% in PAL and 29% in UNR and in P₂ and P₃ cases of REC-C, 75% in PAL and 33% in UNR. Concerning the mean survival, there was no difference between PAL and UNR though the ratio of discharge was better in PAL. In P₀, P₁ and P₂ cases of REC-G and P₀ and P₁ cases of REC-C, there was no decrease in survival according to operative stress of the resection if the resection was palliative. We concluded that operative treatment should be tried for intraperitoneal invasive recurence if there is a possibility of decreasing the symptoms.
