Autologous bone marrow transplantation for adult advanced stage lymphoblastic lymphoma in first CR. A study of the NHLCSG.

Fourty successive adult patients with lymphoblastic lymphoma entered a study of sequential chemotherapy consisting of an intensive LSA-L2-type protocol to induce first complete remission. Twenty-one patients in first CR (median age 24 years, range 15-43), after receiving a conditioning regimen consisting of cyclophosphamide and total body irradiation, underwent autologous bone marrow transplantation. At this time fourteen patients are alive and well 5-72 months post-transplant (median follow-up 58 months) with an actuarial disease free survival of 66%. These early results suggest that high-dose chemoradiotherapy followed by autologous bone marrow transplantation may improve long-term disease free survival in advanced stage adult lymphoblastic lymphoma.
