Filter by:This phase I-II trial is intented to demonstrate tolerability (i.e. absence of severe non-hematological toxicity) and efficacy of intended intervention with repeated doses of Voraxaze, in addition to leucovorin (LV), in patients with renal impairment or renal failure during previous HD-MTX therapy. Patients will receive up to 6 cycles of HD-MTX treatment with 14 days between cycles (a maximum delay of 28 days is permitted in order to allow time for a patient to recover from the previous cycle).
The purpose of this study is to compare different estimates of calculating creatinine clearance by mathematical formula and compare them to creatinine clearance based on a timed urine collection in patients who received high-dose methotrexate for the treatment of primary CNS lymphoma or CNS involvement of systemic lymphoma.
Current standard treatments for lymphoma involving the central nervous system include chemotherapy or whole brain radiation therapy (WBRT). However, many patients do not respond to this treatment, and some of the patients who do respond relapse after treatment. Previous research has shown that a stem cell transplant of a patient's own cells (autologous stem cell transplant) may be more effective for some patients with lymphoma involving the CNS. In previous research using autologous stem cell transplants for lymphoma involving the CNS, a conditioning regimen consisting of the drugs thiotepa, busulfan and cyclophosphamide (TCE) was used. These drugs have been shown to enter the nervous system. In this research study, the investigators are adding the drug rituximab (Rituxan) to the drug cytarabine for the stem cell mobilization process. Cytarabine is a standard drug for mobilization. In addition, rituximab will be added to the conditioning regimen of thiotepa, busulfan and cyclophosphamide. Rituximab is approved by the FDA for the treatment of some types of lymphomas, but is not approved for use in lymphomas that involve the CNS. Rituximab is known to be able to enter the CNS. Previous research has suggested that it may help treat lymphoma that involves the CNS. The goal of this research study is to see if adding rituximab to the stem cell mobilization and conditioning regimens helps treat lymphoma that involves the central nervous system.
The purpose of this study is to evaluate the complete response (CR) rate after HD-MTX induction chemotherapy followed by alternative HD MTX-based and HD Cytarabine-based combination consolidation chemotherapy
The purpose of this study is to determine the safety of this new treatment offered in this study. PCNSL can be cured in less than half of patients with standard treatment, a combination of chemotherapy and brain radiation. Also, the combination of chemotherapy and brain radiation may result in serious lasting side effects. Most patients older than age 60 develop memory problems, difficulty walking or inability to control their bladder. Some patients younger than age 60 also develop these side effects.
