||MT2003-13 Autologous Transplantation for Multiple Myeloma
||This clinical trial is studying how well giving cyclophosphamide and melphalan followed by an autologous stem cell transplant together with dexamethasone and thalidomide works in treating patients with previously treated multiple myeloma.
||Patients receive high-dose cyclophosphamide IV, filgrastim (G-CSF) and undergo stem cell collection. Patients with an insufficient number of stem cells are removed from study. Beginning 2-4 weeks later, patients deemed suitable by the principal investigator receive high-dose melphalan IV and undergo autologous peripheral blood stem cell transplantation. Patients also receive G-CSF (growth hormone) until blood counts recover. Patients may receive radiotherapy. After blood counts recovery, patients receive maintenance therapy comprising dexamethasone and thalidomide. Treatment with dexamethasone and thalidomide may continue for up to 1 year in the absence of unacceptable toxicity.
||Drugs used in chemotherapy, such as cyclophosphamide, melphalan, and dexamethasone, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. A stem cell transplant may be able to replace blood-forming cells that were destroyed by chemotherapy. Giving chemotherapy with a stem cell transplant, using stem cells from the patient, may allow more chemotherapy to be given so more cancer cells are killed. Thalidomide may stop the growth of cancer cells by blocking blood flow to the cancer. Giving maintenance therapy, using dexamethasone and thalidomide, after an autologous stem cell transplant may kill any cancer cells that remain.
