Rhabdomyosarcoma in children in the light of isotope ratio mass spectrometry

Polish Journal of Pathology, 2016
Rhabdomyosarcoma is the third most common solid tumor in children and the most common soft tissue sarcoma in this age group. However, 5-year survival is only observed in approximately 70% of cases, and the prognosis for patients with progressive disease is still poor.
