RESUMO
We report a now 74-year-old patient who was successfully treated with a methotrexate (MTX)-ssbased polychemotherapy protocol (Bonn protocol) for primary central nervous system lymphoma (PCNSL) in 1996. When presenting with an unusually late relapse after 13 years of tumor-free survival the diagnosis was made on the basis of clinical and radiological criteria. In the context of the very limited treatment options for recurrent PCNSL, it is reassuring that the re-application of high dose-MTX-based polychemotherapy, including intraventricular treatment, again succeeded in a sustained complete response with still low neurotoxicity.

After failure of temozolomide, there is no established standard salvage chemotherapy for patients with recurrent glioblastoma (GBM). Two phase II trials combining ifosfamide, carboplatin and etoposide chemotherapy (ICE) showed favorable results. We therefore applied the ICE protocol to 13 patients (10 GBM, 3 anaplastic astrocytomas). Partial or complete remissions were not observed. None of the 13 patients survived progression-free for 6 months. Our retrospective analysis suggests that the ICE regimen is not effective in patients with recurrent high-grade glioma if applied at second or third relapse.

BACKGROUND: In a previous trial (NOA-01), the combination of nimustine and teniposide showed efficacy in previously untreated glioblastoma (GBM). After establishing temozolomide as standard first-line therapy in GBM patients, the nimustine (ACNU)/teniposide (VM-26) combination has been employed as salvage chemotherapy for recurrent GBM. However, data on the toxicity and efficacy of this regimen in recurrent GBM are lacking. PATIENTS AND METHODS: In two neurooncological centers, all patients with recurrent GBM treated with nimustine (90 mg/m(2), day 1/42) and teniposide (45-70 mg/m(2), days 1-3/42) were analyzed retrospectively for progression-free survival (PFS), overall survival (OS) and toxicity. RESULTS: Thirty-five patients (median age 51 years, range 25-71 years) were identified. Six months after chemotherapy initiation, PFS was 29% and the median OS 6 months; 23% of patients were alive > or = 1 year after initiation of nimustine-teniposide chemotherapy. Grade 4 hematotoxicity was observed in 12 of 35 patients (34%) and in 14 of 83 evaluable chemotherapy courses (17%). CONCLUSIONS: The benefit of the nimustine-teniposide combination is moderate in patients with recurrent GBM. The data support the efficacy of the nimustine-teniposide chemotherapy, but the rate of high-grade hematotoxicity is increased.
