简要总结
To determine the efficacy of high-dose topotecan, cyclophosphamide and melphalan in patients with Multiple Myeloma.
详细描述
Patients in this study will have a catheter (a tube) placed in the vein below the collarbone. Most of the drugs used in the study will be given through the catheter. Blood stem cells will be collected through this tube also.
Before treatment starts, patients will have a complete physical exam, including blood and urine tests. A dentist will perform a dental exam either at M.D. Anderson or elsewhere. A chest x-ray and bone x-rays will be done. An EKG and a heart scan will be done to test heart function. A breathing test will be done. Patients will also be screened for HIV and Hepatitis.
Blood stem cells will be collected from patients when white blood cell counts are normal. This will be after earlier chemotherapy or after a bone marrow growth factor (G-CSF) has been given. Collecting stem cells takes about 3 hours. It takes from 1 to 6 sessions to get the needed amount of cells. The process is called apheresis. A machine is attached to the catheter, and blood is drawn. The machine removes the stem cells from the blood and the blood is then returned to the body through the catheter. G-CSF is injected under the skin twice a day during the time the stem cells are collected. The stem cells are stored frozen and will be used later to help patients recover from the high-dose chemotherapy.
After stem cells are collected, patients will receive high-dose chemotherapy. Cyclophosphamide is given over 2 hours on Days 1 - 3. Melphalan is given on Days 4 and 5. Topotecan is given over 30 minutes on Days 1 - 5, right after cyclophosphamide or melphalan. On Day 6, no drugs are given. On Day 7, some or all of the stem cells will be reinfused. G-CSF will be given once a day until blood counts return to normal.
Patients must stay in the hospital for the high-dose drug treatment. The length of stay will be about 3 weeks. Blood tests will be done daily while in hospital, then once a week for the first month. A bone marrow sample will be taken on Day 30. Blood samples will be taken 4 times in the first year and once a year after that. Thyroid gland tests and a bone marrow test will be done once a year.
