[A case of unresectable gastric cancer with poor ingestion].
We encountered cases of unresectable gastric cancer in which patients had difficulty with ingestion because of pyloric stenosis and diffuse invasion. We examined the improvement in the quality of life(QOL)of patients and the effect and usefulness of S-1 treatment in such cases. The median survival time(MST; 310 days)of patients who received S-1 as primary treatment was significantly longer than that(105 days)of patients who did not receive S-1 treatment(p=0.0001). Of the 25 patients who underwent gastrojejunostomy, S-1 was administered to 10 patients(MST: 384 days). The MST of patients who received drugs other than S-1 was 121 days. Thus, the MST of patients who did receive S-1 was significantly longer than that of patients who did not receive S-1. In univariate analysis, oral ingestion, performance status(PS), best supportive care(BSC), and S-1 administration were prognostic factors. Of these factors, oral ingestion(p=0.0278, hazard ratio[HR]: 2.992)and S- 1 administration(p=0.0002, HR: 14.956)were prognostic factors in multivariate analysis. Gastrojejunostomy is desirable for the treatment of cases of unresectable gastric cancer with poor ingestion. In addition, the use of postoperative chemotherapy with S-1 alone or with S-1 as combination therapy may help improve prognosis.
