Abstract
Survivors of childhood solid tumors including Ewing sarcoma (ES) have an increased risk of secondary malignant neoplasms (SMNs) as a consequence of exposure to chemotherapy and/or radiation (see: Bhatia S, Sklar C. Nat Rev Cancer 2002;2:124-132). The most common hematologic SMNs are myelodysplasia (MDS) and acute myelogenous leukemia (AML). Acute lymphoblastic leukemia (ALL) is uncommon in this patient population, and Philadelphia chromosome positive (Ph+) ALL in particular, is rare. We report herein two cases of young adult patients who were both diagnosed with Ph+ ALL 19 years after successful treatment for ES with combined modality therapy. A review of the relevant literature follows the case reports.
