Abstract

The major obstacle to wider exploration of autologous bone mar-row transplantation in the lymphohematopoietic malignancies is the problem of subdetectable levels of tumor cells in the marrow of patients in complete remission. We report here a patient with a lymphoblastic lymphoma who exhibited a testicular and hematologic relapse. After reinduction therapy, marrow was collected from the patient, treated in vitro with a monoclonal anti T-cell anti-body (α-leu-1), and reinfused after supralethal doses of chemoradiotherapy. The patient exhibited prompt hematologic recovery and his post-transplant course has been benign over more than 20 months of follow-up. He has shown a persistent lymphocytosis of the bone marrow, but most of the marrow lymphocytes are morphologically mature and do not bear the surface antigens characteristic of his initial tumor. Measurements of immunologic function show persistently low levels of serum IgG, but recovery to normal levels of IgA and IgM. Lymphocyte proliferative responses to alloantigens and mitogens are normal. Moreover, the patient has not exhibited any tendency toward recur-rent infection. We conclude that treatment of bone marrow with a monoclonal antibody under conditions that lyse all tumor cells bearing the T-cell antigen, leu-1, is not associated with clinically significant inhibition of hematologic or immunologic recovery. Furthermore, the patient’s continued disease-free status suggests that the antibody treatment may have been effective in eliminating all clonogenic tumor from the remission marrow.
