Background: The histologic classification of rhabdomyosarcoma (RMS) as alveolar (aRMS) or embryonal (eRMS) is of prognostic importance, with the aRMS being associated with a worse outcome. Specific gene fusions (PAX3/7::FOXO1) found in the majority of aRMS have been recognized as markers associated with poor prognosis and are included in current risk stratification instead of histologic subtypes in localized disease. In metastatic disease, the independent prognostic significance of fusion status has not been definitively established.

Background: Orbital rhabdomyosarcoma (RMS) is often limited to the orbital cavity and has a favorable prognosis. In some cases, the tumor can erode the orbital bone and behave as a parameningeal RMS (PM-RMS); thus, it is treated more intensively. However, the current protocols do not provide any guidance on how to consider different grades of bone erosion (BE) that can vary widely, hampering a uniform classification and the subsequent treatment assignment.

Rhabdomyosarcoma (RMS) is the most common soft tissue malignancy in childhood, accounting for 3% of all pediatric malignancies and 50% of all pediatric soft tissue sarcomas. In adolescents and young adults (AYA) however, RMS comprises only 6.5% of all soft tissue sarcomas.

Background: Rhabdomyosarcoma (RMS) is a rare malignant soft tissue sarcoma (STS), accounting for almost 50% of pediatric STSs. Due to its heterogeneity, RMS presents challenges in diagnosis and treatment, with prognosis varying depending on multiple factors. Tumors localized in the other site (OTH)-including the paraspinal, perianal, thoracic, abdominal, pelvic, and perineal regions-are generally classified as unfavorable.
