• Status: Not yet recruiting
• Trial end date: 2021-12-01
• Target enrollment: 0
• Participant gender: All

Summary

This study evaluates the efficacy and safety of surgical intervention in patients with focally progressive GISTs after imatinib treatment. The enrolled patients will be randomized to receive surgery following imatinib 400 milligram per day (MG/d) or only tyrosine kinase inhibitor (Imatinib 600 MG/d or Sunitinib 37.5 MG/d).

• Phase: N/A
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: Shanghai Zhongshan Hospital
• Treatments: Imatinib Mesylate; Sunitinib
