A Phase I Study of S-1 in Combination With Radiotherapy in Locally Advanced or Recurrent Gastric Cancer
This is a Phase I trial of S-1 given in treatment days with an oral dose from 30mg/m2/d to
80mg/m2/d, concurrently with radiation in patients with locally advanced or locally
recurrent gastric cancer. Patients will be treated with external beam radiation therapy in a
standard manner. S-1 will be administered for 6 dose levels,30/40/50/60/70/80mg/m2/d.
Patients will be assessed for acute toxicities according to CTCAE 3.0.
Interventional
Endpoint Classification: Safety/Efficacy Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Treatment
