Study Design
Endpoint Classification: Safety/Efficacy Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Treatment
Name: intensity-modulated radiotherapy Type: Radiation
Name: S-1 Type: Drug
Overall Status
The aim of this phase II trial was to evaluate the feasibility, efficacy and tolerability of intensity-modulated radiotherapy combined with S-1 based chemotherapy in patients with pathologically positive lymph node after completely resected gastric cancer. Furthermore, the investigators sought to compare the dosimetric differences between the volumetric-modulated arc therapy (VMAT), Tomotherapy and intensity-modulated radiotherapy (IMRT) techniques in treatment planning for gastric cancer as adjuvant radiotherapy.
