[Course of metastatic osteogenic sarcoma treated with chemotherapy only (author's transl)].

The case of a six year old girl with metastatic (or primarily multifocal) osteogenic sarcoma is reported, which was treated with chemotherapy only. Within 15 months--the primary tumor regressed and at least a transient inactivation has resulted until now;--the pulmonary metastases showed no progression;--an osteoplastic destruction of the sacrum has completely regressed. At the time of report (15 months after initiation of treatment) neither on X-ray controls nor on bone scan signs of tumor regrowth are evident. The child is without any complaints and the leg has no loss of function.
