Abstract
- Therapy-related myeloid neoplasms have been well characterized. However, precursor B-cell acute lymphoblastic leukemia in patients with prior malignancies is uncommon, and the effect of prior cytotoxic therapy on development of precursor B-cell acute lymphoblastic leukemia is controversial. Therapy-related precursor B-cell acute lymphoblastic leukemia has been reported occasionally. However, cytotoxic therapy-related precursor B-cell acute lymphoblastic leukemia has been reported in Korea only rarely. We herein describe two cases of therapy-related precursor B-cell acute lymphoblastic leukemia.
