Patients And Methods: Sixty-two patients (39 males, 23 females: median age 14) with biopsy, chest computerised-tomography, technetium bone-scan and magnetic resonance imaging, were enrolled. Primary localisations were femur (44%) and tibia (26%).
Purpose: We analyzed the clinical features and outcome of patients with radiation-associated osteosarcoma treated during the era of contemporary chemotherapy.
Patients And Methods: The characteristics and outcome of 23 patients (17 males and six females) treated during childhood or adolescence for a solid tumor who later developed osteosarcomas within the radiation field between 1981 and 1996 were reviewed.
Results: The median dose of radiation delivered to the first cancer was 47 Gy.
