Summary
RATIONALE: Giving chemotherapy drugs, such as cytarabine and mitoxantrone, before a donor stem cell transplant helps stop the growth of cancer cells and helps stop the patient's immune system from rejecting the donor's stem cells. When certain 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. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving cyclosporine, methotrexate, and methylprednisolone before or after transplant may stop this from happening. PURPOSE: This phase I/II trial is studying the side effects and best way to give high-dose cytarabine together with mitoxantrone in treating patients with juvenile myelomonocytic leukemia undergoing a second donor stem cell transplant.

Criteria
Inclusion Criteria:

- Patients age 0-18 with juvenile myelomonocytic leukemia (JMML) who have relapsed or
have residual disease after allogeneic HCT. Residual disease is defined as failure to
eradicate original disease without prior documentation of remission. Relapse is
defined as reappearance of i) leukocytosis with absolute monocytosis >1 x 10^8/L, ii)
presence of immature myeloid cells in the peripheral circulation in two consecutive
bone marrow specimens taken at least one month apart, or iii) presence of clonal
cytogenetic abnormality. The diagnosis of relapse will be supported by the return of
an abnormal cytogenetic marker (if present at diagnosis) or the presence of host cells
by RFLP or other method.

- Patients should be at least 6 months from first hematopoietic cell transplant (HCT) if
clinically stable. (If JMML is rapidly progressive, second HCT may be performed
earlier).

- Adequate major organ function including:

- Cardiac: ejection fraction ≥45%

- Pulmonary: FEV >50%, DLCO >50%

- Renal: creatinine clearance ≥40 mL/min

- Hepatic: no clinical evidence of hepatic failure (e.g. coagulopathy,
ascites)

- Karnofsky performance status ≥70% or Lansky score ≥50%

- Written informed consent.

Exclusion Criteria:

- Active uncontrolled infection within one week of HCT.
