To compare the clinical outcome of autologous peripheral blood stem cell transplantation (APBSCT) and autologous bone marrow transplantation (ABMT) in treatment of patients with acute leukemia in first remission, 41 patients received APBSCT, 17 patients received unpurged ABMT and 30 patients received purged ABMT. The results showed that hematopoietic recovery was significantly earlier after APBSCT than that after purged or unpurged ABMT. The 3-year disease-free survival (DFS), relapse rate (RR) and transplant-related mortality (TRM) for all patients of 3 groups were 51.7%, 41.7% and 6.8%, respectively. DFS and RR were significantly influenced by disease types (ALL or AML) and intervals between diagnosis and CR(1) or CR(1) and transplant. The main causes of transplant-related death were infection and hemorrhage. After APBSCT, DFS, RR and TRM were 48.4%, 43.9% and 4.9%, respectively, and did not differ significantly from those found in unpurged ABMT (47.1%, 45.6% and 11.8%) or purged ABMT (66.5%, 29.6% and 6.7%). It is concluded that the clinical outcome of APBSCT is similar to unpurged or purged ABMT but APBSCT allows faster recovery of hematopoiesis and needs less transfusion support.

Combination chemotherapy and radiation therapy have contributed to the successful treatment of various cancer patients. But the development of second malignancies is an inevitable complication of long-term cytotoxic treatment. The most serious and frequent of such complications is acute myelogenous leukemia (AML). Therapy-related leukemia is generally fatal. Since the number of patients exposed to chemotherapy is increasing each year, the clinical significance of this entity cannot be underestimated. There have been many investigations of therapy-related leukemia, but in Korea published reports are rare. We describe four such cases, involving one older female with lung cancer and three children with acute lymphoblastic leukemia (ALL) and malignant lymphoma. Alkylating agents were used for chemotherapy, and in one case, topoisomerase II inhibitor. Irrespective of the causative agents, the latency periods were relatively short, and despite induction chemotherapy in two, all survived for only a few months. During the follow-up of patients treated for primary malignancies, the possibility of therapy-related leukemia should always be borne in mind.
