PURPOSE: This phase II trial is studying how well tandem (two) autologous stem cell transplantation works in treating patients with primary systemic (AL) amyloidosis.
- Determine the tolerability of tandem autologous stem cell transplantation in patients with AL amyloidosis.
- Determine whether this regimen can convert a hematologic non-complete response (CR) to CR in these patients.
- Determine the overall survival of patients treated with this regimen.
- First transplantation: Patients receive filgrastim (G-CSF) subcutaneously once daily beginning 3 days before the initiation of stem cell collection and continuing until the day before the completion of stem cell collection. Patients may undergo bone marrow harvest if an inadequate number of peripheral blood stem cells are collected.
Patients receive high-dose melphalan IV over 20 minutes on days -3 and -2. Patients undergo autologous stem cell transplantation (ASCT) on day 0.
- Second transplantation: Within 6-12 months after the first ASCT, patients not achieving a complete response receive high-dose melphalan IV over 20 minutes on days -3 and -2 and a second ASCT on day 0.
Treatment continues in the absence of unacceptable toxicity.
Patients are followed at 3 and 6 months, 1 year, and then annually thereafter.
PROJECTED ACCRUAL: A total of 62 patients will be accrued for this study within 2-3 years.

Iodine I 131 Metaiodobenzylguanidine, Combination Chemotherapy, and Radiation Therapy in Treating Patients Who Are Undergoing an Autologous Peripheral Stem Cell or Bone Marrow Transplant for Relapsed or Refractory Neuroblastoma
RATIONALE: Radioactive drugs, such as iodine I 131 metaiodobenzylguanidine, may carry radiation directly to tumor cells and not harm normal cells. Drugs used in chemotherapy, such as carbo...

RATIONALE: Chemotherapy, such as busulfan, melphalan, and thiotepa, may destroy cancerous blood-forming cells (stem cells) in the blood and bone marrow. Giving the patient their healthy st...
Peripheral Blood (PB) or Bone Marrow (BM) from unrelated donors can serve as a graft source for hematopoietic cell transplantation. Currently, PB is most commonly used in roughly 80% of adult recipien...
As graft versus host disease (GVHD) rates are higher after unrelated donor transplantation, we examined whether there would be differences in transplant outcomes by graft type in children and adolesce...
Cardiac deposition of misfolded light chains is the leading cause of morbidity and mortality in patients with immunoglobulin (AL) amyloidosis. Cardiac defibrillators can be used in the management of p...
Bone remodeling takes place in the bone marrow environment. We investigated if levels of bone turnover markers (BTMs) differ between bone marrow and peripheral blood, if the bone marrow is an independ...
Transfer of HEMATOPOIETIC STEM CELLS from BONE MARROW or BLOOD between individuals within the same species (TRANSPLANTATION, HOMOLOGOUS) or transfer within the same individual (TRANSPLANTATION, AUTOLOGOUS). Hematopoietic stem cell transplantation has been used as an alternative to BONE MARROW TRANSPLANTATION in the treatment of a variety of neoplasms.
Transplantation of stem cells collected from the peripheral blood. It is a less invasive alternative to direct marrow harvesting of hematopoietic stem cells. Enrichment of stem cells in peripheral blood can be achieved by inducing mobilization of stem cells from the BONE MARROW.
Techniques for the removal of subpopulations of cells (usually residual tumor cells) from the bone marrow ex vivo before it is infused. The purging is achieved by a variety of agents including pharmacologic agents, biophysical agents (laser photoirradiation or radioisotopes) and immunologic agents. Bone marrow purging is used in both autologous and allogeneic BONE MARROW TRANSPLANTATION.
A cell-separation technique where magnetizable microspheres or beads are first coated with monoclonal antibody, allowed to search and bind to target cells, and are then selectively removed when passed through a magnetic field. Among other applications, the technique is commonly used to remove tumor cells from the marrow (BONE MARROW PURGING) of patients who are to undergo autologous bone marrow transplantation.
Agents that destroy bone marrow activity. They are used to prepare patients for BONE MARROW TRANSPLANTATION or STEM CELL TRANSPLANTATION.
Organ transplantation is the moving of an organ from one body to another or from a donor site to another location on the patient's own body, for the purpose of replacing the recipient's damaged or absent organ. The emerging field of regenerative ...
In a clinical trial or interventional study, participants receive specific interventions according to the research plan or protocol created by the investigators. These interventions may be medical products, such as drugs or devices; procedures; or change...
