Bone marrow transplantation for severe aplastic anemia secondary to temozolomide

Radiotherapy (RT) and concomitant/adjuvant therapy with temozolomide (Temodar) is a common treatment regimen for children and adults with glioma. Although temozolomide is generally well tolerated with temporary myelosuppression as the primary dose-limiting toxicity, irreversible bone-marrow aplasia after treatment with temozolomide has been reported. We report the case of an adolescent patient with a high-grade glioma who, after >2 years of event-free survival, underwent successful bone marrow transplantation for treatment of temozolomide-induced severe aplastic anemia (SAA).
