PURPOSE: We have developed and evaluated a CNS-targeted chemotherapy regimen based on the pharmacokinetic properties of the individual drugs in the combination. PATIENTS AND METHODS: In a twin-track study, 16 patients with secondary CNS lymphoma (SCNSL) and 8 with primary CNS lymphoma (PCNSL) were treated with IDARAM which comprised idarubicin 10 mg/m(2) i.v., days 1 and 2; dexamethasone 100 mg, 12-h infusion, days 1, 2 and 3; cytosine arabinoside (ARA-C) 1.0 g/m(2), 1-h infusion, days 1 and 2; methotrexate 2.0 g/m(2), 6-h infusion, day 3 (with folinic acid rescue); and cytosine arabinoside 70 mg plus methotrexate 12 mg, intrathecally, days 1 and 8. Two cycles were delivered at 3-weekly intervals. After response assessment, patients received adjuvant cranial radiotherapy (40 Gy over 20 fractions). RESULTS: The series comprised 24 patients, 11 male and 13 female. Their median age was 53 years (range 21 to 73 years). Grade 4 neutropenia and thrombocytopenia occurred in the majority of patients treated. Of the eight PCNSL patients, seven achieved complete remission (CR). Four remained in CR at the time of this report with a median duration of follow-up of 25 months (range 11 to 42 months). Of the 16 SCNSL patients, 12 achieved CR. Seven patients remained in CR at the time of this report with a median duration of follow-up of 24 months (range 18 to 57 months). CONCLUSION: This study suggests that IDARAM is an effective regimen in both PCNSL and SCNSL and is suitable for further development and evaluation.
