RATIONALE: Radiation therapy uses high-energy x-rays to kill cancer cells. It is not yet known which regimen of low-dose radiation therapy is more effective in treating follicular non-Hodgkin's lymphoma.
PURPOSE: This randomized phase III trial is studying two different regimens of low-dose radiation therapy (24Gy versus 4Gy) to compare how well they work in treating patients with follicular or marginal zone non-Hodgkin's lymphoma.
|Condition or disease||Intervention/treatment||Phase|
|Lymphoma||Radiation: radiation therapy||Phase 3|
- Compare the local progression-free interval in patients with follicular non-Hodgkin's lymphoma (NHL) treated with 2 different regimens of low-dose radiotherapy.
- Compare acute toxicity at 4 weeks in patients treated with these regimens.
- Compare late toxicity in patients treated with these regimens.
- Compare tumor response at 12 weeks in patients treated with these regimens.
- Compare overall survival in patients treated with these regimens.
- Assess the health economics of these regimens in these patients.
OUTLINE: This is a multicenter, randomized study. Patients are randomized to one of two treatment arms.
- Arm I 4Gy: Patients undergo low-dose radiotherapy once daily on days 1 and 2.
- Arm II 24Gy: Patients undergo low-dose radiotherapy once daily on days 1-5, 8-12, 15, and 16.
In both arms, treatment continues in the absence of disease progression or unacceptable toxicity.
After completion of study therapy, patients are followed up for 5 years.
