Treating Patients With Recurrent PCNSL With Carboplatin/BBBD and Adding Rituxan To The Treatment Regimen
A Phase II Trial Involving Patients With Recurrent PCNSL Treated With Carboplatin/BBBD, by Adding Rituxan (Rituximab), An Anti CD-20 Antibody, To The Treatment Regimen
RATIONALE: Monoclonal antibodies, such as rituximab, can locate cancer cells and either kill them or deliver cancer-killing substances to them without harming normal cells. Drugs used in chemotherapy, such as carboplatin, cyclophosphamide, etoposide, etoposide phosphate, and cytarabine, use 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 tumor. Chemoprotective drugs such as sodium thiosulfate may protect normal cells from the side effects of carboplatin-based chemotherapy. Combining rituximab with chemotherapy given with osmotic blood-brain barrier disruption plus sodium thiosulfate may kill more cancer cells.
PURPOSE: Phase II trial to study the effectiveness of combining rituximab with combination chemotherapy given with osmotic blood-brain barrier disruption plus sodium thiosulfate in treating patients who have refractory or recurrent primary CNS lymphoma.

Conditions
Detailed Description
OBJECTIVES:
Primary
- Determine the efficacy of rituximab, carboplatin, cyclophosphamide, etoposide or etoposide phosphate and cytarabine administered in conjunction with osmotic blood-brain barrier disruption and high-dose sodium thiosulfate, in terms of complete response rate, in patients with refractory or recurrent primary CNS lymphoma.
Secondary
- Determine the overall survival and 2-year progression-free survival of patients treated with this regimen.
- Determine the quality of life and cognitive function of patients treated with this regimen.
- Determine the neurotoxicity of this regimen in these patients.
- Determine the percentage of patients with ototoxicity over time after treatment with this regimen.
- Determine the effect of delayed administration of sodium thiosulfate on granulocyte and erythrocyte counts in these patients.
OUTLINE: This is a multicenter study.
Patients receive rituximab IV on day 1. On days 2 and 3, patients receive carboplatin intra-arterially over 10 minutes, cyclophosphamide IV over 10 minutes, and etoposide or etoposide phosphate IV over 10 minutes in conjunction with blood-brain barrier disruption. Patients also receive high-dose sodium thiosulfate IV over 15 minutes administered 4 and 8 hours after carboplatin on days 2 and 3 and intraventricular or intrathecal cytarabine on day 14. Beginning 48 hours after the last dose of chemotherapy, patients receive filgrastim (G-CSF)* subcutaneously (SC) daily for 7-10 days or until blood counts recover. Treatment repeats every 4 weeks for up to 12 courses.
NOTE: * Alternatively, patients may receive a single dose of pegfilgrastim SC, administered 48 hours after the completion of chemotherapy
Patients with intraocular lymphoma also receive methotrexate intravitreally twice weekly until the vitreous is clear of cells by slit lamp exam; once weekly for 1 month; and then monthly for 1 year.
Quality of life is assessed at baseline, every 3 months during treatment, within 30 days of final treatment, then every 6 months for 1 year, and then annually thereafter.
Patients are followed monthly for 3 months, every 2 months for 8 months, every 3 months for 1 year, and then every 6 months thereafter.
PROJECTED ACCRUAL: A total of 11-25 patients will be accrued for this study within 7-10 years.
