RATIONALE: Drugs used in chemotherapy, such as methotrexate, cyclophosphamide, etoposide phosphate, dexamethasone, and cytarabine, work in different ways to stop cancer cells from dividing so they stop growing or die. Osmotic blood-brain barrier disruption uses certain drugs to open the blood vessels around the brain and allow anticancer substances to be delivered directly to the brain. Giving methotrexate, cyclophosphamide, and etoposide phosphate with osmotic blood-brain barrier disruption plus dexamethasone and cytarabine may kill more cancer cells.

PURPOSE: Phase II trial to study the effectiveness of giving methotrexate, cyclophosphamide, and etoposide phosphate with osmotic blood-brain barrier disruption plus dexamethasone and cytarabine in treating patients who have primary CNS lymphoma.

Primary Outcome Measures:
  • Survival as measured by clinical and radiographic response at 5 years after study treatment

Secondary Outcome Measures:
  • Overall survival as measured by clinical and radiographic response
  • Progression-free survival as measured by clinical and radiographic response until tumor progression
  • Quality of Life (QOL) as measured by EORTC QOL before and after study treatment, every 6 months for 2 years, and then annually

Enrollment: 22
Study Start Date: January 2000
Study Completion Date: July 2006
Primary Completion Date: July 2006 (Final data collection date for primary outcome measure)
Detailed Description:



  • Determine the toxicity and efficacy of methotrexate, cyclophosphamide, and etoposide phosphate administered in conjunction with osmotic blood-brain barrier disruption and dexamethasone and cytarabine in patients with primary CNS lymphoma.


  • Determine the ability to recruit an adequate number 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 this patient population.
  • Correlate neuropsychological outcomes with neuroimaging (MRI) outcomes in patients treated with this regimen.

OUTLINE: This is a multicenter study.

Patients receive methotrexate (MTX) intra-arterially over 10 minutes, cyclophosphamide IV over 10 minutes, and etoposide phosphate IV over 10 minutes on days 1 and 2 in conjunction with osmotic blood-brain barrier disruption. Patients also receive oral dexamethasone every 6 hours on days 2-15 (followed by a taper) and intraventricular or intrathecal cytarabine on day 14. Beginning 48 hours after the last dose of MTX, patients receive filgrastim (G-CSF)* subcutaneously once daily for 7-10 days or until blood counts recover. Treatment repeats every 4 weeks for 12 courses in the absence of disease progression or unacceptable toxicity.

NOTE: *Alternatively, patients may receive a single dose of pegfilgrastim, administered 24 hours after the completion of chemotherapy

Patients with intraocular lymphoma also receive MTX intravitreally twice weekly until the vitreous is clear of cells by slit lamp exam and then weekly for 1 month and monthly for 1 year.

Quality of life is assessed at baseline, at 6 months, at the completion of treatment, and then every 6 months for 2 years and 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 90 patients will be accrued for this study within 3 years.


Ages Eligible for Study:   16 Years to 75 Years   (Child, Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No


  • Histologically or cytologically confirmed intermediate- or high-grade primary CNS lymphoma by brain biopsy or cerebrospinal fluid or vitrectomy analysis
  • No more than 90 days since diagnosis
  • 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.
