A Phase I Study of S-1 in Combination With Radiotherapy in Locally Advanced or Recurrent Gastric Cancer

Summary

The purpose of this study is to determine maximum tolerated dose (MTD), dose limiting toxicities (DLT) and recommend a proper dose for our phase II study of S-1 when combined with radiation therapy for locally advanced or recurrent gastric cancer.
