Target enrollment:
0
Participant gender:
All
Summary
RATIONALE: Chemoprevention therapy is the use of certain drugs to try to prevent the development or recurrence of cancer. Celecoxib may be effective in preventing cancer in patients with Barrett's esophagus. PURPOSE: Randomized phase II trial to study the effectiveness of celecoxib in preventing cancer in patients who have Barrett's esophagus.
Phase:
Phase 2
