“…To improve the situation, autologous bone marrow transplantation (ABMT) combined with high dose chemotherapy has been tried (Humblet et al, 1987;Symann et al, 1989;Souhami et al, 1989;Williams et al, 1989;Marangolo et al, 1989;Nomura et al, 1990;Lazarus et al, 1990;Gomm et al, 1991). This treatment has increased the number of patients with complete remissions (Humblet et al, 1987;Souhami et al, 1989) and improved relapse free-survival (Humblet et al, 1987;Symann et al, 1989), but, unfortunately, the long time survival rate has not increased significantly.…”
