简要总结
RATIONALE: Giving total marrow and total lymph node irradiation together with low doses of chemotherapy before a donor stem cell transplant helps stop the growth of cancer cells. It may also stop the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune cells and help destroy any remaining cancer cells (graft-versus-tumor effect).
PURPOSE: This phase I trial is studying the side effects and best dose of total marrow and total lymph node irradiation when given together with fludarabine and melphalan followed by donor stem cell transplant in treating patients with advanced hematological cancer that has not responded to treatment.
详细描述
OBJECTIVES:
Primary
- To determine the maximum tolerated dose of intensity-modulated total marrow and lymph node irradiation (TMLI) using helical tomotherapy in combination with a reduced-intensity preparative regimen comprising fludarabine phosphate and melphalan in patients undergoing allogeneic hematopoietic stem cell transplantation for advanced, relapsed or refractory hematological malignancies.
- To describe the toxicities of escalating doses of TMLI in these patients.
Secondary
- To describe the frequency of clinical response in patients treated with this regimen.
- To describe the frequency of primary and secondary engraftment failure in patients treated with this regimen.
- To describe the time to neutrophil and platelet engraftment in patients treated with this regimen.
- To describe the incidence of acute and chronic graft-versus-host disease in patients treated with this regimen.
- To describe the overall survival of patients treated with this regimen.
- To describe the progression-free survival of patients treated with this regimen.
