Experience with a cooperative bone marrow transplantation program in Stockholm

Area of Science:

• Hematology
• Oncology
• Transplantation Medicine

Background:

• Bone marrow transplantation (BMT) is a critical treatment for hematologic malignancies and aplastic anemia.
• The feasibility of BMT outside highly specialized centers remains a key consideration for wider patient access.

Purpose of the Study:

• To evaluate the efficacy and safety of bone marrow transplantation for severe aplastic anemia (SAA) and acute leukemia.
• To determine if BMT can be successfully performed using standard hospital resources.

Main Methods:

• A cooperative bone marrow transplantation program included 27 patients (ages 1-55).
• Patients with SAA and acute leukemia in remission underwent BMT.
• Outcomes were assessed based on survival rates, complications, and resource utilization.

Main Results:

• For severe aplastic anemia (SAA), 75% (6/8) of patients survived between 3 months and 4.5 years post-transplant.
• For acute leukemia in remission, 76% (13/17) of patients survived 1-16 months post-transplant; all deaths occurred in patients over 17.
• No relapses were observed in the leukemia cohort, and transplantations were performed using only ordinary hospital resources.

Conclusions:

• Bone marrow transplantation is a viable and successful treatment for SAA and acute leukemia in remission.
• The success of these transplantations using standard resources supports their implementation outside specialized BMT units.
• Pediatric patients with acute leukemia demonstrated particularly favorable outcomes, with all children surviving and remaining relapse-free.
