[Results of Primary chemotherapy and Delayed Surgical Resection in Osteosarcoma (author's transl)]

Primary systemic therapy with delayed surgical intervention has been employed for the treatment of malignant bone tumours since 1977 at the Universitäts-Kinderklinik and III. Medizinische Abteilung Graz. Improved therapeutic results, as originally reported on a large number of patients at the Memorial Sloan Kettering Cancer Center (MSKCC) seem to have been attained with a small group of patients (n = 5).
