This study evaluates observation, radiation therapy, combination chemotherapy, and/or surgery in children and young patients with soft tissue sarcoma. It included newly diagnosed patients with non-rhabdomyosarcoma soft tissue sarcoma. It was a Phase 3 study and has been completed.
The summary above is a plain-language rendering of the official record. The original English title is shown for reference.

Criteria are reproduced from the ClinicalTrials.gov record in the original English. Only the trial team can determine eligibility.

* Clear cell myomelanocytic tumor
* Intimal sarcoma
* Malignant peripheral nerve sheath tumor
* Dermatofibrosarcoma protuberans meeting both of the following criteria:
* Non metastatic disease
* Tumor must be grossly resected prior to study enrollment
* Embryonal sarcoma of the liver
* Unclassified STS that is too undifferentiated to be placed in a specific pathologic category (undifferentiated STS or STS NOS)
* Gross resection of the primary tumor ≤ 42 days prior to enrollment required except if any of the following circumstances apply:
* Non metastatic high-grade tumor \> 5 cm in maximal diameter and gross or microscopic residual tumor is anticipated after resection
* Tumor of either high- or- low-grade that cannot be grossly excised without unacceptable morbidity
* High-grade tumor with metastases
* Patients with metastatic low-grade tumor whose disease is amenable to gross resection at all sites must undergo gross resection of all sites prior to study entry
* Patients with a tumor recurrence after a gross total resection are not eligible
* Tumors arising in bone are not eligible
* Patients with epithelioid sarcoma, clear cell sarcoma, or clinical or radiologic evidence of regional lymph node enlargement must undergo sentinel lymph node biopsies or lymph node sampling to confirm the status of regional lymph nodes\* NOTE: \*Except in cases where the study radiologist reviews the imaging and indicates that a biopsy is not needed to confirm that the patient has lymph node involvement.
* If lymph node biopsies are positive for tumor (or the lymph nodes are classified as positive by the study radiologist), formal lymph node dissection must be done at the time of definitive surgery(prior to study entry for patients assigned to study regimen C)
* Patients with metastatic disease must undergo a biopsy to confirm the presence of metastatic tumor if all metastases are \< 1 cm in maximal diameter (except in cases where the study radiologist reviews the imaging and indicated that a biopsy is not needed to confirm that the patient has metastatic disease)

* 0.4 mg/dL (1 month to \< 6 months of age)
* 0.5 mg/dL (6 months to \< 1 year of age)
* 0.6 mg/dL (1 year to \< 2 years of age)
* 0.8 mg/dL (2 years to \< 6 years of age)
