Recently, treatment of leukemia has shown remarkable progress. Development of new antileukemic drugs, improvements in supportive care and rapid progress in bone marrow transplantation have resulted in considerable changes in responses in refractory leukemia. Chemotherapy for Acute leukemia: By the introduction of Mitoxantrone and etoposide and a new combination chemotherapy including them, a high remission rate of acute leukemia is obtained, but because of the high relapse rate the 5-year survival rates in our center were 20% for adult ALL and 18% for ANL. In order to reduce the relapse rate, a new regimen containing intensive consolidation treatments is now being studied in a nation-wide cooperative study. BMT: In 1987, 160 BMTs including 75 acute leukemia and 28 CML, were registered in Japan. The improvements in the management of graft versus host disease (GVHD) and infections in the granulocytopenic period has contributed to the marked increase in the long-term survival rate after BMT. In our center the long-term survival rate rose from 20% before 1984 to 85% after 1985. Colony stimulating factor: Macrophage-colony stimulating factor (M-CSF) and granulocyte colony stimulating factor (G-CSF) were studied in Japan. In the double-blind placebo controlled study of M-CSF, a significantly shorter duration of granulocytopenia, as well as a significantly lower rate of failure of BMT (i.e., death or retransplant) was observed. In the phase II study of G-CSF, a rapid recovery of granulocytes after chemotherapy or BMT and marked efficacy on infection in granulocytopenic patients were observed.

Mitoxantrone (Mito) is presently used in an increasing number of malignancies including leukemias, breast carcinomas and solid tumors. With it has come increased incidence of post remission cytopenias and delayed engraftment following autologous bone marrow transplantation (ABMT). We evaluated engraftment in 18 patients who underwent allogeneic BMT (allo-BMT) following a preparative regimen that included high dose Mito (60 mg m2). Sixteen patients with malignant disease (AML 10, ALL 3, CML 2, MDS 1) and two with non-malignant disease (SCID 1, osteopetrosis 1) underwent non-T cell depleted allo-BMT. Fourteen patients with malignancies were transplanted at an advanced stage of disease while only two patients were standard risk patients. Of the 18 patients, 12 were females and six males, with a median age of 30.5 (0.3-48) years. Nine patients, (breast cancer 3, malignant lymphoma 4 and AML 2), who underwent ABMT following preparative regimens with comparable doses of Mito, served as controls. Engraftment following allo-BMT was normal and not statistically different from engraftment following ABMT. Five patients, who underwent allo-BMT, developed >grade II acute graft versus host disease (GVHD) and two developed chronic GVHD. After a median follow up of 28 (6-42) months, five patients are alive (one with disease). In summary, engraftment following high dose Mito and allo-BMT is not statistically different from engraftment following ABMT. Controlled studies with a larger group of standard risk patients are needed to elucidate the role of Mito in conditioning regimens pre-BMT.
