F4-150

For details of chemotherapy-regimens, see references.

F4-151

The percentage of patients with CNS involvement. In most reports, this includes patients with CNS involvement at presentation. When specified, the percentage of patients with CNS involvement at presentation is shown in the next column.

B-symptoms, histology, extranodal involvement, response to therapy and gender are not associated with risk for CNS recurrence.
