Eligibility Criteria:
Inclusion Criteria:~1. No age restrictions~2. Only subjects who are not appropriate candidates for autologous or HLA-matched sibling hematopoietic cell transplants (HCT) may be enrolled.~3. Diseases eligible~   1. High Risk Neuroblastoma (NB): Must have progressed on or recurred after standard frontline therapy including autologous HCT, or be ineligible for autologous HCT.~  2. Ewing Sarcoma Family of Tumors (EWS) \[includes both bone and soft tissue Ewing and Peripheral Primitive Neuroectodermal Tumors (PNET)\]. Must have progressed on or recurred after standard frontline therapy which includes doxorubicin and ifosfamide.~  3. High-Risk Rhabdomyosarcoma (RMS) or Intermediate Risk Alveolar RMS recurring as more than loco-regional tumor: Must have progressed on or recurred after standard frontline therapy which includes chemotherapy with vincristine, actinomycin, and cyclophosphamide AND either surgery or radiotherapy.~  4. Osteosarcoma: Must have progressed or recurred after standard frontline therapy. If first relapse, must have recurred with a) ≥ 4 lung nodules; b) bilateral lung involvement; or c) relapse outside the lungs.~  5. CNS tumors: High risk malignant brain tumors that are recurrent or refractory to standard frontline therapy are eligible. Diagnoses include: Medulloblastoma, primitive neuro-ectodermal tumor (PNET), ependymoma, high grade (grade 3 or 4) glioma/astrocytoma, germ-cell tumor, or atypical teratoid-rhabdoid tumor (ATRT)~Exclusion Criteria~1. Rapidly-progressing disease prior to HCT, defined as clinical or radiographic evidence of disease progression ≤ 3 weeks prior to protocol registration despite previous achievement of stable or no disease (Appendix C \& D) (Note: after disease eligibility has been determined, additional imaging studies are not necessary during the three weeks before the start of conditioning unless there are clinical concerns).~2. Patients who have reached radiation threshold limits and are excluded from receiving 3 Gy TBI.~3. Diffuse intrinsic pontine gliomas (DIPG) are excluded.~4. Performance status: Karnofsky or Lansky \<60% Note: Patients who are unable to walk because of paralysis, but who are up in a wheelchair, will be considered ambulatory for the purpose of assessing the performance score~5. Patients, who in the opinion of the investigator, may not be able to comply with the treatment plan or safety monitoring requirements of the study Page 16 of 86 Children's Hospital of Wisconsin Medical College of Wisconsin PI: Monica S. Thakar, MD~6. Significant organ dysfunction that would prevent compliance with conditioning, GVHD prophylaxis, or would severely limit the probability of survival, defined as:~   1. Cardiac: For patients not taking inotropic medications and who do not have cardiac failure requiring therapy: Symptomatic coronary artery disease or ejection fraction \<35% or, if unable to obtain ejection fraction, shortening fraction of \<26%. If shortening fraction is \<26% a cardiology consult is required with the PI having final approval of eligibility. For patients taking inotropic medications: Patients displaying corrected cardiac function will be eligible, i.e., patients who take inotropic medications to maintain EF ≥ 35% and SF≥ 26% cardiac function eligibility.~  2. Pulmonary: DLCO \<40% TLC \<40%, FEV1 \<40% and/or receiving supplementary continuous oxygen~  3. Liver: Patient with clinical or laboratory evidence of liver disease will be evaluated for the cause of liver disease, its clinical severity in terms of liver function, bridging fibrosis, and the degree of portal hypertension. The patient will be excluded if he/she is found to have fulminant liver failure, cirrhosis of the liver with evidence of portal hypertension, alcoholic hepatitis, esophageal varices, a history of bleeding esophageal varices, hepatic encephalopathy, uncorrectable hepatic synthetic dysfunction evinced by prolongation of the prothrombin time, ascites related to portal hypertension, bacterial or fungal liver abscess, biliary obstruction, chronic viral hepatitis with total serum bilirubin \>3mg/dL, or symptomatic biliary disease~7. Patients with serious active infections~8. HIV seropositive patients~9. Patients with poorly controlled hypertension despite multiple antihypertensive medications~10. Fertile females who are unwilling to use contraceptive techniques during and for the twelve months following treatment, as well as females who are pregnant or actively breast feeding~11. Fertile males who are unwilling to use contraceptive techniques during and for the twelve months following treatment~12. Life expectancy severely limited by diseases other than malignancy~13. Patients who have received a prior allogeneic HCT are ineligible~DONOR SELECTION An Unrelated Donor Search is not required for entry on this trial. Lack of HLA-matched related or unrelated donors is not a requirement for entry on this trial.~A. Inclusion Criteria~1. Related, HLA-haploidentical donors who are identical for one HLA haplotype and mismatched for any number of HLA-A, -B, -C, DRB1 or DQB1 loci of the unshared haplotype.~2. Marrow will be prioritized as the hematopoietic stem cell source of choice. In cases where adequate stem cells cannot be collected, fresh (preferred) or cryopreserved donor PBSC may be substituted. In the case that PBSC are used, the donor must be 18 years of age or older.~3. HLA-haploidentical donor selection will be based on standard institutional criteria; otherwise no specific prioritization will be made amongst the suitable available donors.~B. Exclusion Criteria~1. Children less than 12 years of age (marrow) or less than 18 years of age (PBSC).~2. Children greater than or equal to 12 years of age who have not provided informed assent in the presence of a parent and an Attending physician who is not a member of the recipient's care team~3. Children greater than or equal to 12-17.9 years of age who have inadequate peripheral vein access to safely undergo apheresis~4. Donors unable or unwilling to undergo marrow harvest or PBSC collection for the initial HCT, storage of autologous blood prior to marrow harvest (if applicable), or apheresis one week after marrow harvest~5. Donors who are not expected to meet the minimum target dose of marrow cells (1 x 108 total nucleated cells/kg recipient weight) for the initial marrow HCT or PBSC transplant (5.0 x 106 CD34/kg recipient weight). The average nucleated cell content of harvested marrow is 22 x 106 nucleated cells/mL or 220 x 108 total nucleated cells/Liter~6. HIV-positive donors~7. Donors who are cross-match positive with recipient
