Successful treatment of non-Hodgkin's lymphoma of the central nervous system with BMPD chemotherapy followed by radiotherapy.
The treatment of patients with primary non-Hodgkin's lymphoma of the central nervous system (PCNSL) is still of limited success, as compared with other extranodal sites. The poor results obtained with radiotherapy alone can be improved by adding chemotherapy reaching a median survival up to over 30 months and 5-years-survival rate up to 35%. The optimal management for patients with CNS relapse of systemic lymphoma remains uncertain and their prognosis is even worse. Here, we describe our preliminary data on the treatment of patients with CNS lymphoma with a new regimen composed of CNS-penetrating drugs, namely: carmustine (BCNU) 80 mg/m2 i.v. dl, methotrexate 1500 mg/m2 over 24h i.v. d2, procarbacine 100 mg/m2 p.o. d1-8, and dexamethasone 3 x 8 mg p.o. d1-14. An average of 3 treatment courses were given under response control seen using CT-scan or NMR. Patients with positive CSF cytology received additionally intrathecal therapy with methotrexate. Until now between March 1994 and September 1997, 7 patients with PCNSL and 4 patients with CNS relapse of systemic lymphoma have been treated. The median age of the patients was 56 (range, 39-74); 5 patients were > or =60 years old. Three patients had multifocal disease. Whole brain radiotherapy with 4000 to 5000 cGy was given in 7 patients (cerebrospinal in 1 patient). Complete response at the end of chemotherapy was achieved in 6 patients, and a partial response in two. Most remarkably, 2 elderly patients (70 and 57 years), 1 patient with multifocal disease and 1 with simultaneous CNS and systemic relapse after chemotherapy had a complete remission lasting for 40 months, and a partial remission lasting for 37 months, respectively.
