  • Patients who have had a major surgical procedure (such as laparotomy, thoracotomy, open biopsy, or resection of tumor) can only be enrolled on study > 28 days from such procedure
• Peripheral absolute neutrophil count (ANC) ≥ 750/μL
• Platelet count ≥ 75,000/μL (transfusion independent, defined as without transfusion for ≥ 1 week prior to enrollment)
• Hemoglobin ≥ 8.0 g/dL (may receive packed red blood cells [PRBC] transfusions)
• Bone marrow disease involvement of tumor is allowed, however, peripheral blood count criteria must still be met
• Creatinine clearance or radioisotope glomerular filtration rate (GFR) ≥ 70 mL/min/1.73 m^2 OR a serum creatinine based on age/gender as follows:
  • ≤ 0.4 mg/dL (for patients aged 1 month to < 6 months)
  • ≤ 0.5 mg/dL (for patients aged 6 months to < 1 year)
  • ≤ 0.6 mg/dL (for patients aged 1 to < 2 years)
  • ≤ 0.8 mg/dL (for patients aged 2 to < 6 years)
  • ≤ 1 mg/dL (for patients aged 6 to < 10 years)
  • ≤ 1.2 mg/dL (for patients aged 10 to < 13 years)
  • ≤ 1.4 mg/dL (for female patients aged ≥ 13 years)
  • ≤ 1.5 mg/dL (for male patients aged 13 to < 16 years)
  • ≤ 1.7 mg/dL (for male patients aged ≥ 16 years)
• Urine protein level:
  • Patients aged ≤ 17 years: Urine protein to creatinine (UPC) ratio should be calculated; UPC ratio must be ≤ 1 for patient to be eligible
  • Patients aged > 17 years: Urine protein should be screened by urine analysis; if protein is 2+ or higher, 24-hour urine protein must be obtained and the level must be < 1,000 mg for patient enrollment
• Total bilirubin ≤ 1.5 x upper limit of normal (ULN) for age
• Shortening fraction of ≥ 27% by echocardiogram or ejection fraction of ≥ 50% by radionuclide angiogram

Exclusion Criteria:

• Patients with botryoid histology, any stage or group, are ineligible
• Patients with embryonal histology, stage I or clinical group 1 at initial disease presentation, who present with local or regional recurrence, are ineligible
• Patients who previously received craniospinal irradiation are ineligible
• Patients who previously received vinorelbine, bevacizumab, temsirolimus, or any other direct vascular endothelial growth factor (VEGF)/vascular endothelial growth factor receptor (VEGFR-) or mammalian target of rapamycin (mTOR-) targeting agents are ineligible
• Patients with known central nervous system (CNS) disease (excluding intracranial/intraspinal extension secondary to local progression of a parameningeal or paraspinal primary), except for those with treated brain metastasis, are ineligible
  • Treated brain metastases are defined as having no ongoing requirement for steroids and no evidence of progression or hemorrhage after treatment for at least 3 months, as ascertained by clinical examination and brain imaging (magnetic resonance imaging [MRI] or computed tomography [CT]); stable dose of anticonvulsants are allowed; treatment for brain metastases may include whole-brain radiotherapy (WBRT), radiosurgery (RS; Gamma Knife, linear accelerator [LINAC], or equivalent), or a combination as deemed appropriate by the treating physician
  • Patients with CNS metastases treated within 3 months prior to enrollment by neurosurgical resection or brain biopsy are ineligible
• Patients who receive radiation or chemotherapy (inclusive of palliative intent) for first disease progression or relapse of rhabdomyosarcoma prior to enrollment are ineligible
• Female patients who are pregnant are ineligible
• Lactating females are not eligible unless they have agreed to discontinue breastfeeding
