Summary
Study start date: January 1, 2000
Actual date on which the first participant was enrolled.OBJECTIVES: Primary * Determine the toxicity and efficacy of methotrexate, procarbazine, lomustine, dexamethasone, and cytarabine in patients with primary CNS lymphoma. Secondary * Determine the ability to recruit adequate numbers of patients for this study. * Compare progression-free and dementia-free survival with standard measures of overall survival, progression-free survival, disease-free survival, complete response rate, cognitive function, and quality of life of patients treated with this regimen. * Determine the feasibility of conducting a future phase III study of this treatment regimen in these patients. * Correlate neuropsychological outcomes with neuroimaging (MRI) outcomes in patients treated with this regimen. OUTLINE: This is a nonrandomized, multicenter study. * Induction chemotherapy: Patients receive methotrexate IV over 3 hours on days 1, 10, and 20 and intraventricularly or intrathecally (IT) over 5 minutes on days 1, 5, 10, and 15; oral procarbazine on days 1-7; oral lomustine on day 1; oral dexamethasone every 6 hours on days 1-14 followed by a taper (as tolerated); and cytarabine intraventricularly or IT over 5 minutes on days 1, 5, 10, and 15. Treatment repeats every 42 days for a total of 3 courses. Patients with intraocular lymphoma also receive methotrexate intravitreally twice weekly until the vitreous is clear of cells by slit lamp exam. Patients with stable or responding disease proceed to maintenance therapy. * Maintenance chemotherapy: Patients receive methotrexate IV over 3 hours and IT over 5 minutes on day 1; oral procarbazine on days 1-7; oral lomustine on day 1; oral dexamethasone every 6 hours on days 1-14 followed by a taper (as tolerated); and cytarabine intraventricularly or IT over 5 minutes on day 1. Treatment repeats every 42 days for a total of 5 courses. Patients with intraocular lymphoma also receive methotrexate intravitreally weekly for 1 month and then monthly for 1 year. Quality of life is assessed at baseline, at 6 months, at the completion of treatment, every 6 months for 2 years, and then annually thereafter. Patients are followed every 3 months for 1 year, every 6 months for 2 years, and then annually thereafter. PROJECTED ACCRUAL: A total of 180 patients will be accrued for this study within 3 years.

Criteria
DISEASE CHARACTERISTICS: * Histologically or cytologically confirmed intermediate- or high-grade primary CNS lymphoma documented by brain biopsy or cerebrospinal fluid or vitrectomy analysis * Diagnosed within the past 90 days * No systemic lymphoma NOTE: A new classification scheme for adult non-Hodgkin's lymphoma has been adopted by PDQ. The terminology of "indolent" or "aggressive" lymphoma will replace the former terminology of "low", "intermediate", or "high" grade lymphoma. However, this protocol uses the former terminology. PATIENT CHARACTERISTICS: Age * 16 to 75 Performance status * ECOG 0-3 OR * Karnofsky 40-100% Life expectancy * Not specified Hematopoietic * WBC at least 2,500/mm\^3 * Hematocrit at least 25% (transfusion allowed) * Absolute granulocyte count at least 1,200/mm\^3 * Platelet count at least 100,000/mm\^3 OR at least lower limit of normal (transfusion independent) Hepatic * Bilirubin no greater than 2.0 times upper limit of normal Renal * Creatinine clearance at least 30 mL/min Cardiovascular * Adequate cardiac function to tolerate general anesthesia Pulmonary * Adequate pulmonary function to tolerate general anesthesia Other * Not pregnant or nursing * Negative pregnancy test * Fertile patients must use effective contraception for 2 months before and during study participation * No other uncontrolled, clinically significant confounding medical condition within the past 30 days * No known allergy to study agents * HIV negative PRIOR CONCURRENT THERAPY: Biologic therapy * Not specified Chemotherapy * More than 4 weeks since prior chemotherapy (6 weeks for nitrosoureas) * Single-agent methotrexate administered within the past 14 days allowed Endocrine therapy * Not specified Radiotherapy * No prior cranial or spinal radiotherapy Surgery * Prior surgery or biopsy allowed
