JHOC-NABTT-9607, NCI-T97-0049

Objectives

I.    Determine the response rate of primary central nervous system lymphoma 
to induction therapy with systemic methotrexate.

II.   Assess the time to progression, site of relapse, and toxicity of 
systemic methotrexate in patients with primary central nervous system lymphoma.

III.  Assess the survival time and quality of life of this patient population.

Entry Criteria

Disease Characteristics:


Histologically proven primary central nervous system lymphoma of the following
types:
 Non-Hodgkin's B-cell lymphoma by brain biopsy or resection
 Intracranial disease by positive cytology or immunohistochemical diagnosis of
  monoclonality
 Vitreal lymphoma with measurable intracranial tumor

Disease must be confined to eye, brain, leptomeninges, or CSF


Prior/Concurrent Therapy:


Biologic therapy:
 No prior transplant 
  
Chemotherapy:
 No prior chemotherapy for primary central nervous system lymphoma
 No concurrent chemotherapy

Endocrine therapy:
 No concurrent immunosuppressive treatment

Radiotherapy:
 No prior cranial radiotherapy 

Surgery:
 Prior biopsy or resection allowed

Other:
 At least 1 week since salicylates, non-steroidal anti-inflammatory drugs, or
  sulfonamides


Patient Characteristics:


Age:
  18 and over

Performance status:
  Karnofsky 60-100%

Life expectancy:
  At least 2 months

Hematopoietic:
 WBC at least 1500/mm3
 Platelet count at least 100,000/mm3

Hepatic:
 Bilirubin no greater than 2.0 mg/dL
 SGOT/SGPT no greater than 4 times upper limit of normal

Renal:
 Creatinine no greater than 2.0 mg/dL OR
 Creatinine clearance at least 50 mL/min

Other:
 Not allergic to methotrexate
 Not HIV positive
 No preexisting immunosuppression
 Not pregnant or nursing
 No prior malignancy within 5 years except basal cell skin cancer or carcinoma
  in situ of the cervix

Expected Enrollment

A total of 25 patients will be accrued for the study.

Outline

Patients receive induction chemotherapy with high-dose methotrexate 
intravenously every 14 days for 4 to 8 courses of treatment.  Patients with 
complete response receive consolidation therapy with methotrexate for 2 more 
courses, followed by maintenance therapy with monthly methotrexate IV for 11 
months.  Patients not achieving a complete response after 8 courses of 
induction therapy are removed from study.

Quality of life is assessed before treatment, then at 3 and 12 months, and
annually thereafter.  Patients are followed for survival every 2 months or 
until death.

Note: The purpose of most clinical trials listed in this database is to test new cancer treatments, or new methods of diagnosing, screening, or preventing cancer. Because all potentially harmful side effects are not known before a trial is conducted, dose and schedule modifications may be required for participants if they develop side effects from the treatment or test. The therapy or test described in this clinical trial is intended for use by clinical oncologists in carefully structured settings, and may not prove to be more effective than standard treatment. A responsible investigator associated with this clinical trial should be consulted before using this protocol.
