Chemotherapy in Treating Children With Recurrent or Refractory Sarcomas

• Status: Completed
• Trial end date: 1969-12-31
• Target enrollment: 0
• Participant gender: All

Summary

Phase II trial to study the effectiveness of topotecan in treating children who have recurrent, relapsed, or refractory sarcoma. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die.

• Phase: Phase 2
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: National Cancer Institute (NCI)
• Treatments: Topotecan

Criteria
