Primary malignant lymphoma of the brain. A report of 24 cases from the Norwegian Radium Hospital.

Between 1975 and 1987, 24 patients with primary central nervous system lymphoma were seen and treated at the Norwegian Radium Hospital. The overall median survival was 24 months. Patients with poor performance status (WHO 3-4) had a median survival of 3 months whereas patients with good performance status (WHO 0-2) had a median survival of 40 months (p < 0.0001). Patients who were not steroid-dependent after operation had a better survival than those patients who were steroid-dependent (p = 0.02). Nine patients were still living without evidence of disease at last follow-up, 18-130 months after the initial treatment.
