Bone tumours comprise about 5% of childhood neoplasms. Osteosarcoma is the most common sub-type and constitutes 60 % of all bone cancers. Incidence is similar in girls and boys and is increasing steeply with age. The most common localization of this tumour is long bones of the legs. Treatment including chemotherapy and surgery has led to an increase of the percentage of non-mutilating recovery. We present treatment results of 14 children with osteosarcoma.
