A childhood soft-tissue sarcoma, a cancer of muscle-like cells found anywhere from the eye socket to the bladder. Most children are cured with chemotherapy, surgery and radiation, and a fusion gene (PAX-FOXO1) now decides how intensively to treat.
Rhabdomyosarcoma (RMS) has two main types: embryonal (~70%, younger children, RAS-pathway mutations, favourable) and alveolar (~25%, adolescents, PAX3- or PAX7-FOXO1 fusion in ~80%, unfavourable). Fusion status has replaced histology in risk stratification since fusion-negative alveolar RMS behaves like embryonal. Sites range from orbit and parameningeal head and neck to genitourinary and extremity; risk groups combine site, size, nodal status, metastases, age and fusion status.
Therapy is VAC (vincristine, actinomycin D, cyclophosphamide) in North America or IVA (ifosfamide) in Europe, with local control by surgery and/or radiotherapy at week ~13. Key trial results: adding irinotecan (VAC/VI, ARST0531) did not improve outcomes but reduced cyclophosphamide exposure; maintenance vinorelbine-cyclophosphamide after standard therapy improved survival in high-risk localised disease (EpSSG RMS 2005, Lancet Oncol 2019); temsirolimus added to chemotherapy improved event-free survival in intermediate-risk disease (ARST1431, reported 2024). Metastatic disease (especially bone/marrow, age >10) has survival under 30% and is the target of the FaR-RMS international trial. Relapse is usually fatal outside low-risk cases.
Averages across everyone diagnosed, often years ago. A median is the middle of a group: half the people counted lived longer than the figure shown, and some lived far longer. Your stage, subtype, age, fitness and the treatment you receive matter more than the average, and the numbers are improving quickly.

Bone sarcomas favour the fast-growing ends of long bones (osteosarcoma) or the shaft (Ewing), soft tissue sarcomas the deep muscle compartments; spread is through the blood to the lungs, rarely via lymph nodes.
Lymph node spread is rare (except epithelioid, synovial, clear cell and rhabdomyosarcoma); sarcomas go through the blood to the lungs.

Bleeding that does not stop by itself, bleeding from more than one site, or new bruising in several places or one large area.
Cumulative dose: risk rises steeply above 400-550 mg/m² (see the anthracycline calculator).
UGT1A1*28 homozygotes: consider a lower starting dose (neutropenia). Cholinergic syndrome: atropine.
Take on an empty stomach or at bedtime to reduce nausea; PJP prophylaxis during concurrent chemoradiation.
Fatal if given intrathecally: label all syringes.
Reduce to 75% for CrCl 15-50.
