RESUMEN
We have several choices against bleeding and obstruction in advanced gastric cancer patients such as surgical or endoscopic therapy. But we have few reports about palliative radiation. We conduct this study that we perform palliative radiation for unresectable advanced gastric cancer patients between April 2006 and March 2014 in single center. In the aim of the therapy, to stop gastric bleeding were 8, and to improve obstruction depend on gastric cancer were 4. Response rate of stop bleeding was 63％, and improve obstruction was 50％. Median duration of stop bleeding was 103 day, and improve obstruction was 52 day. Overall survival time was 567 day, survival time after the start of radiotherapy was 105days. Radiotherapy was limited in cases because onset time of response needed in comparison with surgical or endoscopic therapy. However, given minimally invasive therapy and a certain response, we can choice it so much more.
