Description:
The investigators hypothesize that long-term disease-free survival (DFS) in patients with
JMML can be achieved with a treatment of busulfan (BU), cyclophosphamide (CY) and melphalan
(L-PAM) followed by hematopoietic cell transplantation (HCT).

Purpose
The investigators hypothesize that long-term disease-free survival (DFS) in patients with
JMML can be achieved with a treatment of busulfan (BU), cyclophosphamide (CY) and melphalan
(L-PAM) followed by hematopoietic cell transplantation (HCT).
Detailed Description
Prior to transplantation, subjects will receive BUSULFAN via the central venous line, six
times a day for four days, CYCLOPHOSPHAMIDE via the central venous line once a day for two
days, and MELPHALAN via the central venous line for one day. Busulfan, cyclophosphamide, and
melphalan are given to destroy the subject's leukemia. As well, these drugs will destroy the
subject's own immune system to help ensure the new bone marrow takes and grows after
transplantation.
On the day of transplantation, bone marrow or umbilical cord blood from the donor will arrive
to the bone marrow transplant unit and be transfused via venous line. These new cells will
replace the subject's bone marrow.
