Cases of stage IV gastric cancer accounted for 30.6% of the cases of gastric cancer subjected to laparotomy and for 23.2% of the cases of gastric cancer treated by resection. By curatice operation, the cases were broken down to absolute cure 11 cases, relative cure 14 cases, relative non-cure 49 cases and absolute non-cure 243 cases. The mean number of days of survival after operation was 1222, 686, 897 and 293 days respectively, there being a significant difference (p<0.005) between the absolute non-cure and relative cure. The prognosis of inoperable stage IV gastric cancer (129 cases) was significantly poor (p<0.0001) compared with stage IV gastric cancer for which resection was done (320 cases). As for the prognosis by the type of operation, there was a significant difference (p<0.0001) among partial resection and total gastrectomy, subtotal gastrectomy, but no difference was found between other types of operation. As for the stage IV factors, cases of single factor accounted for 40.6%. The late result was best in factor S, followed by factor P, factor N and factor H in this order. In the 2 factor cases, the survival period was the longest in SP followed by SN, HN, PN and SH, but no significant difference was found between them except SP>SH (p<0.05), nor was there any significant difference between the 3 factor cases. Regarding the number of non-cure factors with the residue of cut end cancer added, cases with 1 factor accounted for 35.3%, of which late result was significantly better compared with the cases having 2 or more factors. We concluded that it is reasonable that of the cases of stage IV gastric cancer, those of n4, P2-3 and H1-3 be subclassified as IVb., 長崎大学医療技術短期大学部紀要 = Bulletin of the School of Allied Medical Sciences, Nagasaki University. 1993, 6, p.63-72}, pages = {63--72}, title = {Stage Ⅳ胃癌切除症例の検討}, volume = {6}, year = {1993} }
