RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. Combining radiation therapy with a corticosteroid, such as dexamethasone, may be an effective treatment for non-Hodgkin's lymphoma. PURPOSE: Phase II trial to study the effectiveness of radiation therapy and high-dose dexamethasone in treating older patients with primary CNS non-Hodgkin's lymphoma.
OBJECTIVES: * Assess the effectiveness of high-dose dexamethasone after whole-brain radiotherapy in maintaining response and preventing recurrence in elderly patients with primary central nervous system non-Hodgkin's lymphoma. * Assess the toxic effects of this regimen in these patients. * Assess the survival rate of patients after this regimen. * Identify the anatomic rates of recurrence and frequency of systemic involvement in patients treated with this regimen. * Identify the factors that appear to be associated with outcome in patients treated with this regimen. OUTLINE: Patients undergo whole-brain radiotherapy (WBRT) daily 5 days a week for 4.5 weeks. Beginning 30 days after WBRT is completed, patients receive high-dose dexamethasone IV on days 1-5 during course 1 and on day 1 only during all subsequent courses. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients are followed at 1 month after radiotherapy, every 3 months for 2 years, every 6 months for 3 years, and then annually thereafter. PROJECTED ACCRUAL: A total of 28 patients will be accrued for this study within 6 years.
