Trial Summary

What is the purpose of this trial?

RATIONALE: Giving chemotherapy drugs, such as fludarabine phosphate and melphalan, and HT before a donor stem cell transplant helps stop the growth of cancer cells. It also helps 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. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving HT together with fludarabine phosphate and melphalan before a transplant may stop this from happening. PURPOSE: This clinical trial studies helical tomotherapy (HT), fludarabine phosphate, and melphalan followed by donor stem cell transplant in treating patients with hematologic malignancies.

Eligibility Criteria

This trial is for patients with certain blood cancers like AML, high-risk MDS, or ALL. They must be able to lie still in a body cast for treatment sessions and have good heart, lung, liver, and kidney function. Excluded are those with specific leukemia types (AUL), prior extensive radiation therapy, HIV infection, uncontrolled infections or serious recent infections.

Inclusion Criteria

I can lie on my back for 30 minutes without moving, even if it means I might need sedation.

Patients must have less than 15% peripheral blasts

Recipient, or recipient's parents, or recipient's legal guardians must have signed a voluntary, informed consent in accordance with institutional and federal guidelines

Experimental Treatment

Group I: Treatment (enzyme inhibitor, radiation therapy, transplant)Experimental Treatment4 Interventions

PREPARATIVE REGIMEN\*: Patients receive fludarabine phosphate IV on days -7 to -3 and melphalan IV on day -2. Patients also undergo helical tomotherapy twice daily on days -7 to -4. TRANSPLANTATION: Patients undergo allogeneic hematopoietic stem cell transplantation on day 0. NOTE: \*Treatment begins 2 days earlier in patients receive tacrolimus and/or sirolimus for GVHD prophylaxis.

Fludarabine Phosphate is already approved in Canada, Japan for the following indications:
