- Treatment-Related Mortality (TRM) Defined as Non Relapse Mortality (NRM) [ Time Frame: 100 Days ]NRM was defined as death from any cause other than disease progression or relapse and reported as percentage of participant deaths. Treatment related deaths after transplant are defined either by deaths which could not be attributed to disease relapse or progression or by deaths without previous relapse or progression. For TRM at day 100, Bayesian method of Thall, Simon, and Estey used to perform interim monitoring.

Ages Eligible for Study: | up to 65 Years (Child, Adult, Older Adult) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
Inclusion Criteria:
- Patients with biopsy-proven acute lymphoblastic leukemia, acute lymphoblastic lymphoma, or acute biphenotypic leukemia in remission or relapse.
- Adequate renal function, as defined by estimated serum creatinine clearance >60 ml/min.
- Bilirubin equal or less than 1.5 (unless Gilbert's Syndrome), serum glutamate pyruvate transaminase (SGPT) <3 X upper limit of normal and alkaline phosphatase <2 X upper limit of normal.
- Adequate pulmonary function with forced expiratory volume at one second (FEV1), forced vital capacity (FVC) and diffusion capacity of lung for carbon monoxide (DLCO) at least 45% of expected corrected for hemoglobin. Children unable to perform pulmonary functions must have an oxygen saturation greater than 92% at room air.
- Adequate cardiac function with left ventricular ejection fraction at least 45% on appropriate medical therapy. No uncontrolled arrhythmias or symptomatic cardiac disease.
- Zubrod performance status <2 or Lansky/Karnofsky PS equal or greater to 70%.
- Patients must have a related, genotypically HLA identical donor, or they must have a unrelated donor who is 8/8 HLA match by high resolution typing.
- Patient or patient's legal representative, parent(s) or guardian should provide written informed consent. Assent of a minor if participant's age is at least seven and less than eighteen years.
- Negative Beta Human Chorionic Gonadotropin (HCG) test in a woman with child bearing potential defined as not post-menopausal for 12 months and no previous surgical sterilization.
Exclusion Criteria:
- Patients with unresolved grade >2 non-hematologic toxicity from previous therapy. Patients with grade 2 toxicity will be eligible at the discretion of the PI.
- Patients with active central nervous system (CNS) disease.
- Evidence of acute or chronic active hepatitis or cirrhosis.
- Uncontrolled infection, including HIV, HTLV-1, hepatitis B or hepatitis C viremia.
- Patients greater than 65 years-old.
- Prior autologous or allogeneic hematopoietic stem cell transplant.
