Gedetailleerde beschrijving
OBJECTIVES:
I. Compare the overall survival of patients with multiple brain metastases treated with radiotherapy with or without thalidomide.
II. Compare the time to tumor progression in patients treated with these regimens.
III. Compare the time to neuro-cognitive progression in patients treated with these regimens.
IV. Compare the cause of death distribution in patients treated with these regimens.
V. Compare the frequency of toxic effects of these regimens in these patients. VI. Evaluate and compare the quality of life of patients treated with these regimens.
OUTLINE: This is a randomized, multicenter study. Patients are stratified according to recursive partitioning analysis class (I vs II) and planned chemotherapy after whole brain irradiation (yes vs no). Patients are randomized to 1 of 2 treatment arms.
Arm I: Patients undergo radiotherapy once daily 5 days a week for 3 weeks. Arm II: Patients undergo radiotherapy as in arm I. Beginning on the first day of radiotherapy, patients receive oral thalidomide once daily.
Treatment with thalidomide continues for 2 years in the absence of disease progression or unacceptable toxicity. Quality of life is assessed at baseline, at completion of radiotherapy, and then every 2 months for 1 year.
Patients are followed every 2 months for 1 year, every 4 months for 1 year, every 6 months for 2 years, and then annually thereafter.
PROJECTED ACCRUAL: A total of 332 patients (166 per treatment arm) will be accrued for this study within 14.5 months.
