Abstract
Eight patients with acute lymphosarcoma cell leukemia or acute lymphoblastic leukemia received infusions of plasma containing a lymphotoxic factor. The lymphotoxic factor induced a transient fall in the number of βblastβ cell forms in the peripheral blood in six of the eight patients but did not produce sustained remissions.
Previous investigations have demonstrated that this lymphotoxic factor, found in the plasma of patients with active multiple sclerosis, is of low molecular weight and does not have the properties normally associated with an antibody. This factor appears to selectively interfere with ribonucleic acid synthesis in the thymusderived lymphocyte. Lymphotoxic factor activity was demonstrated in the serum of one patient during a remission in leukemia induced by a viral illness.

## Background: Children with acute lymphoblastic leukemia with multiple poor prognostic factors and who have a lymphomatous mass at diagnosis, whether of t- or non-t-immunophenotype, are at increased risk of short term remission and extramedullary recurrence, and are in need of better therapies. #
