[Gastrojejunostomy followed by chemotherapy with S-1 in unresectable gastric cancer with pyloric stenosis].

We investigated the efficacy of gastrojejunostomy followed by S-1-based chemotherapy for unresectable gastric cancer with pyloric stenosis. We performed gastrojejunostomy and S-1-based chemotherapy in 14 unresectable gastric cancer patients with gastric outlet obstructions between April 2006 and June 2010. Although there were two complications after surgery, no treatment-related deaths were observed. The response rate of the S-1-based chemotherapy was 41.7%, and the median survival after surgery was 12.3 months. All patients were tolerating a regular diet and a significant improvement in oral intake lasted for at least 6 months. In conclusion, gastrojejunostomy followed by chemotherapy with S-1 appears to be an effective treatment modality for unresectable gastric cancer with pyloric stenosis. It enables us to practice S-1-based standard chemotherapy for advanced gastric cancer and improve the quality of life of patients.
