Summary
Brief summary (as posted)
RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. Glutamine may be an effective treatment for acute diarrhea caused by radiation therapy. It is not known if glutamine is an effective treatment for acute diarrhea caused by radiation therapy. PURPOSE: Randomized double-blinded phase III trial to determine the effectiveness of glutamine in preventing acute diarrhea in patients who have pelvic cancer and who are receiving radiation therapy.

- description
- Beginning the first or second day of radiotherapy, patients receive oral glutamine twice daily, including the days that they do not receive radiotherapy. Patients continue on treatment throughout radiotherapy and continue 2 weeks postradiotherapy or until grade 3 diarrhea occurs. Patients are followed weekly for 4 weeks, then at 12 months, and then at 24 months after radiotherapy.
