title: Adjuvant therapy for osteosarcoma: preoperative and postoperative treatment.
abstract: Seventeen consecutive patients with osteogenic sarcoma participated in a prospective study to ascertain first, whether postoperative adjuvant chemotherapy or chemoimmunotherapy could reduce the incidence of distant metastases and second, whether in situ tumor cell destruction could be achieved with preoperative chemotherapy and radiation therapy. To date 14 of 17 patients (85%) are alive and free of disease for a median survival time of 11 months. Three patients developed recurrent disease, one with local recurrence in the tibia and two with pulmonary metastases. Limb salvage was attained in 12 patients by cadaver allografts and in one patient by radiation alone at 6 months.
