Eleven autologous bone marrow transplantations (ABMT) were performed in 10 patients with T lymphoblastic lymphoma. All patients were grafted because of a very bad prognosis: 2 cases of progressive disease (1 primary failure, 1 resistant relapse): 0/2 alive, 2 late complete remissions: 1/2 alive, 7 sensitive relapses (2/7 alive). Finally, 3 out of 10 patients are survived. This salvage therapy for a failure of a front line strategy with 78% disease-free survival without ABMT seems of interest. ABMT is still indicated as salvage therapy for 20% of these patients.
