简要总结
Randomized phase III trial to compare the effectiveness of radiation therapy with or without thalidomide in treating patients who have brain metastases. Radiation therapy uses high-energy x-rays to damage tumor cells. Drugs such as thalidomide may stop the growth of brain metastases by stopping blood flow to the tumor. It is not yet known whether radiation therapy is more effective with or without thalidomide in treating brain metastases.
详细描述
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.
