Zusammenfassung
Das Rhabdomyosarkom, das Osteosarkom und das Ewing-Sarkom sind die am häufigsten auftretenden malignen Tumoren des Muskuloskelettalsystems im Kindes- und Adoleszentenalter. Diese Erkrankungen repräsentieren etwa 10% der bei Kindern und Jugendlichen neu diagnostizierten Tumoren.
In den letzten beiden Jahrzehnten hat sich insgesamt die Prognose der Patienten mit solchen Malignomen deutlich gebessert. Einerseits aufgrund der Fortschritte in der Chemotherapie und orthopädischen Tumorchirurgie, andererseits nicht zuletzt aufgrund der zahlreichen Innovationen der radiologischen Diagnostik. Das präzise prätherapeutische Staging von Tumoren des Muskuloskelettalsystems liefert wichtige prognostische Informationen und beeinflusst das gesamte Therapiemanagement. Während bzw. nach erfolgter Therapie ist die Bildgebung ganz entscheidend im Follow-up und bei der Diagnostik einer möglichen Rezidiverkrankung.
Die moderne bildgebende Diagnostik maligner muskuloskelettaler Tumoren umfasst im Wesentlichen das konventionelle Röntgen, die Computertomographie (CT) und Magnetresonanztomographie (MRT) sowie die nuklearmedizinischen Untersuchungen Szintigraphie, Positronenemissionstomographie (PET) und PET-CT.
Abstract
Rhabdomyosarcoma, osteosarcoma and Ewing’s sarcoma are the most common malignant tumors of the musculoskeletal system in childhood and adolescence representing about 10% of newly diagnosed cancers in children and adolescents.
In the last two decades the prognosis of patients with such malignancies improved significantly. On the one hand because of the advances in chemotherapy and orthopedic surgery, on the other hand also because of the innovations in radiological diagnostics. The precise pre-therapeutical staging of tumors of the musculoskeletal system provides important prognostic information and has impact on the entire therapy management. During respectively after therapy, imaging is extremely important in the follow-up and in diagnosing a possible recurrent disease.
Modern imaging diagnostics of musculoskeletal tumors basically consist of conventional X-ray, of computed tomography (CT) and magnetic resonance imaging (MRI), and of modalities of nuclear medicine such as szintigraphy, positron emission tomography (PET) and PET CT.
