title: Prognostic factors in 140 adult patients with non-Hodgkin's lymphoma with systemic central nervous system (CNS) involvement. A single centre analysis.
abstract: We examined retrospectively the outcome of patients with non-Hodgkin's lymphoma (NHL) with systemic involvement of the central nervous system (CNS) registered at The Norwegian Radium Hospital (NRH) from 1980 to 1996, in order to evaluate our treatment strategy for these patients. 170 of 2561 patients (6.6%) had CNS involvement, 140 (5.5%) systemic CNS lymphoma (SCNSL) and 30 (1.2%) primary CNS lymphoma (PCNSL). Description of the patients, time of SCNSL diagnosis, symptoms at CNS diagnosis, treatment and survival were registered. The overall median survival for the 140 patients with SCNSL was 2.6 months (95% confidence interval (CI) 2.1-3.2), only 12 patients are alive in complete remission (CR). Patients with CNS involvement at diagnosis, relapse or progression during treatment for NHL had a median survival of 5.4 months (95% CI: 0.3-10.6), 3.8 months (95% CI: 0.0-9.1), and 1.8 months (95% CI: 1.0-2. 7), respectively (P=0.001). 5 of the 8 patients consolidated with high-dose therapy (HDT) are in CR. Paresis was the only symptom that predicted survival for SCNSL. Patients above 60 years of age with CNS involvement at progression or relapse and those with paresis at the time of CNS diagnosis have a dismal prognosis. For these patients supportive therapy only should be considered. For patients under 60 years of age with chemosensitive disease, the trend was toward better prospects, and they should be offered intensive chemo-radiotherapy including HDT with autologous stem cell support.
