[Diagnosis and treatment of childhood soft tissue sarcomas]. / Gyermekkori lágyrészsarcomák diagnosztikája és kezelése.

ABSTRACT

Malignant tumors of mesenchymal origin are called sarcomas. Mesenchymal cells normally mature into skeletal muscle, smooth muscle, fat, fibrous tissue, bone and cartilage. Rhabdomyosarcoma (RMS) arises from immature mesenchymal cells that are committed to skeletal muscle lineage. However, it can also arise in tissues in which striated muscle is normally not found (such as the urinary tract). Undifferentiated sarcomas cannot be ascribed to any specific lineage. Treatment results improved significantly in the last decade by combined treatment (chemotherapy, surgery, irradiation, in some cases targeted therapy). Good treatment results can be achieved in pediatric oncology centers by early diagnosis and adequate treatment according to international treatment protocols.
