[CNS complications and their prevention in malignant non-Hodgkin's lymphoma (author's transl)].

Among 334 patients (aged 15-57 years) with malignant non-Hodgkin's lymphoma there were 14 who developed CNS complications, none in 144 with lymphoma of low malignancy. Lymphoblastic lymphoma predominated amoung those with CNS involvement. In adults with this form treatment should therefore be undertaken to prevent such complications. The study confirms the need for histological subclassification in malignant non-Hodgkins's lymphoma.
