Last Updated: 2017-01-18

Basic Information

• Recruitment Status: TERMINATED
• Clinical Phase: PHASE1
• Total Enrollment: 10 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2013-10-31

Brief Summary

The purpose of this study is to determine whether combination of TS-1 and concurrent and short-course radiotherapy is feasible in metastatic pancreatic cancer. The rationale of this study primarily bases on the good efficacy of gemcitabine plus TS-1 and the great potential of local control of concurrent chemoradiotherapy in pancreatic cancer.
