Long term survival in a patient with recurrent metastatic Ewing sarcoma treated with irinotecan and temozolomide

Abstract

Ewing sarcoma family of tumor is the second most common bone tumor in children and young adults, after osteosarcoma. Different chemotherapeutic regimens are used in treatment of relapsed/recurrent Ewing sarcoma. Promising results were achieved with combination of irinotecan and temozolomide. Our case was a 13-year-old female with relapsed Ewing sarcoma and after 12 cycles of irinotecan (20 mg/m2/10 days) and temozolomide (100mg/m2/5 days) treatment she had not any complaints, and her radiological lesions remained stable for 66 months. Irinotecan and temozolomide have been used successfully in treatment of relapsed/recurrent Ewing sarcoma, but there is a need for randomized prospective studies with larger patient groups for establishing the efficacy of this treatment protocol.
