Brief Summary

Cord blood transplants (CBT) are a standard treatment for adults with blood cancers. MSK has developed a standard ("optimized") practice for cord blood transplant (CBT). This optimized practice includes how patients are evaluated for transplant, the conditioning treatment (standard chemotherapy and total body irradiation therapy) given to prepare the body for transplant, the amount of stem cells transplanted, and how patients are followed during and after transplant.The purpose of this study is to collect information about participant outcomes after CBT following MSK's optimized practice. The researchers will look at outcomes of the CBT treatment such as side effects, disease relapse, GVHD, and immune system recovery after CBT treatment.

Cord Blood Transplant

EXPERIMENTAL

Adult patients with high-risk hematologic malignancies and a suitable double-unit CB graft will undergo work-up to assess protocol eligibility. CB graft selection will be based on established MSKCC guidelines. Patients will receive standard conditioning with Cy 50 mg/kg, Flu 150 mg/m2, Thio 10 mg/kg, and TBI 400 cGy according to the eligibility criteria. GVHD prophylaxis will consist of CSA and MMF starting day -3. The double-unit CB graft will be infused on day 0 per standard practice. Optimized CBT practices, will be implemented in this protocol.

Drug: Conditioning ChemotherapyBiological: Cord blood graft

Interventions

Conditioning: Cyclophosphamide (CY) 50 mg/kg x1 (day -6), Fludarabine (FLU) 30 mg/m2 x5 (days -6 to -2), Thiotepa (THIO) 5 mg/kg x2 (days -5 \& -4), Total Body Irradiation (TBI) 200 cGy x2 (days -2 \& -1). GVHD prophylaxis: Cyclosporine (CSA) 3 mg/kg q12 hours \& Mycophenolate Mofetil (MMF) 15 mg/kg q8 hours (starting IV day -3).

Cord Blood Transplant

The double-unit CB graft will be infused on day 0 per standard practice.

  • Two prior stem cell transplants of any kind.
  • One prior autologous stem cell transplant within the preceding 12 months.
  • Prior allogeneic transplantation.
  • Prior involved field radiation therapy that would preclude safe delivery of 400cGy TBI in the opinion of Radiation Oncology.
  • Active and uncontrolled infection at time of transplantation.
  • HIV infection.
  • Seropositivity for HTLV-1.
  • Inadequate performance status/ organ function.
  • Pregnancy or breast feeding.
  • Patient or guardian unable to give informed consent or unable to comply with the treatment protocol including appropriate supportive care, long-term follow-up, and research tests.
