  Purpose
This randomized phase II trial studies how well giving busulfan, cyclophosphamide, and melphalan or busulfan and fludarabine phosphate before donor hematopoietic cell transplant works in treating younger patients with juvenile myelomonocytic leukemia. Giving chemotherapy before a donor hematopoietic transplant helps stop the growth of cancer cells. It may also stop the patient's immune system from rejecting the donor's stem cells. When the healthy stem cells from a donor are infused into the patient, they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. It is not yet known whether giving busulfan, cyclophosphamide, and melphalan or busulfan and fludarabine phosphate before a donor stem cell transplant is more effective in treating juvenile myelomonocytic leukemia.

Primary Outcome Measures:
  • EFS [ Time Frame: 18 months ]
    Will be estimated using the Kaplan-Meier method. An event is either TRM, primary or secondary graft failure, or relapse/non-response (as defined in protocol section 10). Time to event is time from transplant with patients who die between the start of the conditioning regimen and transplant given a time to event of zero.

  • TRM [ Time Frame: Day 100 ]
    Death prior to relapse or non-response. Time to TRM is defined as time from transplants to TRM. Patients who die between the start of the conditioning regimen and transplant will be considered a TRM with time to TRM of zero. Will be estimated as cumulative incidence using the Aalen-Johansen method.


Secondary Outcome Measures:
  • Graft failure rates [ Time Frame: Up to 5 years ]
    Will be estimated using the cumulative incidence via the method of Aalen and Johannsen. Failure to achieve an ANC >= 500/uL after 42 days, determined by 3 consecutive measurements on different days; OR < 5% donor cells in blood or bone marrow by day +42 (as demonstrated by a chimerism assay), without evidence of JMML.

  • Relapse/non-response rates [ Time Frame: Up to 5 years ]
    As defined in protocol section 10. Will be estimated using the cumulative incidence via the method of Aalen and Johannsen.
