[The analysis of failures in therapy of osteosarcoma in children treated according to SFOP-94 protocol in the studies of Polish pediatric solid tumors treatment group].
1998
: Between December 1989 and April 1998 twenty eight children aged from 5 to 20 years (18 female and 10 male) suffering from osteosarcoma were treated according to the OS-SFOP-94 protocol. Twenty four patients presented with localized tumor of extremities and four with pulmonary metastases. The majority of primary tumors exceeded 150 ml of volume. The primary preoperative chemotherapy consisted of adriamycin (70 mg/m2 every four weeks) and high-dose methotrexate (12 g/m2 every week). In 20 patients limb-salvage surgery was applied, in three children--amputation and in one child tibia resection with genu arthrodesis was applied. Five of 28 patients died, one because of treatment related infection, 2 non-responders with metastatic osteosarcoma due to progressive disease, and one because of local relapse with pulmonary metastasis non-responding to therapy, one because of treatment refusal. Twenty one from 25 children are alive from 5 to 51 months. Event frae survival of children with localized disease calculated according to Kaplan-Meier analysis was 64.17% in the 51st month. The main cause of failure in the treatment of osteosarcoma in children is primary and secondary progression of disease. The toleration and results of treatment for osteosarcoma in children according to the OS-SFOP-94 is satisfactory.
