简要总结
RATIONALE: Antiemetic drugs may help to reduce or prevent vomiting in patients treated with radiation therapy. It is not yet known if ondansetron is more effective with or without dexamethasone in preventing vomiting caused by radiation therapy.
PURPOSE: This randomized phase III trial is comparing how well ondansetron works with or without dexamethasone in preventing vomiting in patients with cancer who are receiving radiation therapy to the upper abdomen.
详细描述
OBJECTIVES:
- Compare the effectiveness of ondansetron with or without dexamethasone as prophylaxis for radiation-induced emesis and nausea in patients receiving upper abdominal radiotherapy.
- Compare toxicity of these regimens in these patients.
- Compare quality of life of patients treated with these regimens.
OUTLINE: This is a randomized, double-blind, placebo-controlled, multicenter study. Patients are stratified according to radiotherapy field description (whole abdomen and pelvis vs partial abdomen and pelvis vs partial abdomen only). Patients are randomized to 1 of 2 treatment arms.
- Arm I: Patients receive oral ondansetron twice daily and oral dexamethasone daily for 5-7 days concurrently with the first 5 fractions of radiotherapy.
- Arm II: Patients receive oral ondansetron twice daily and oral placebo daily for 5-7 days concurrently with the first 5 fractions of radiotherapy.
Treatment continues in both arms in the absence of disease progression or unacceptable toxicity.
