Low-Dose Radiation Therapy in Treating Patients With Follicular or Marginal Zone Non-Hodgkin's Lymphoma

Phase 3
Completed
Conditions
Lymphoma
Interventions
Radiation: radiation therapy
Registration Number
NCT00310167
Lead Sponsor
University College, London
Brief Summary

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.

Detailed Description

OBJECTIVES:

Primary

* Compare the local progression-free interval in patients with follicular non-Hodgkin's lymphoma (NHL) treated with 2 different regimens of low-dose radiotherapy.

Secondary

* 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.
