Résumé
Date de début de l'étude : 1 novembre 1994
Date à laquelle le premier participant a commencé l'étude.PROTOCOL OUTLINE: This is a randomized study. Tumor size and number are confirmed prior to randomization. Patients are stratified by participating institution. Patients are randomly assigned to 1 of 2 treatment groups. One group is treated with fractionated whole-brain irradiation using megavoltage equipment. The second group receives stereotactic radiosurgery plus fractionated whole-brain radiotherapy. Stereotactic radiosurgery involves irradiation of all tumors to the margins on stereotactic computerized tomography or magnetic resonance imaging. Either treatment may be administered first; the second treatment begins within 1 month of the first. Concurrent anticonvulsants and steroids are allowed. Patients are followed for change in size and number of tumors at 1, 3, and 6 months; follow-up clinical exams are performed at least every 2 months.
