Filter by:RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Some tumors become resistant to chemotherapy drugs. Combining PSC 833 with chemotherapy may reduce resistance to the drug, and allow more tumor cells to be killed. It is not yet known whether combination chemotherapy plus PSC 833 is more effective than combination chemotherapy alone in treating patients with relapsed or refractory multiple myeloma. PURPOSE: Randomized phase III trial to compare the effectiveness of combination chemotherapy with or without PSC 833 in treating patients with relapsed or refractory multiple myeloma.
RATIONALE: Giving antibiotics may be effective in preventing or controlling early infection in patients with multiple myeloma and may improve their response to chemotherapy. PURPOSE: This randomized clinical trial is studying antibiotics to see how well they work compared to no antibiotics in preventing early infection in patients with multiple myeloma.
RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Deoxycytidine may protect patients from the side effects of high-dose cytarabine. PURPOSE: Phase I trial to study the effectiveness of high-dose cytarabine given with deoxycytidine in treating patients who have refractory acute myelogenous leukemia or other lymphoma or leukemia.
RATIONALE: Drugs used in chemotherapy work in different ways to stop the growth of plasma cells, either by killing the cells or by stopping them from dividing. Having a peripheral stem cell transplant to replace the blood-forming cells destroyed by chemotherapy, allows higher doses of chemotherapy to be given so that more plasma cells are killed. By reducing the number of plasma cells, the disease may progress more slowly. PURPOSE: This phase II trial is studying how well giving high-dose melphalan together with peripheral stem cell transplant works in treating patients with primary amyloidosis or amyloidosis associated with multiple myeloma.
The purpose of this trial is to test the safety and immune response to four immunizations with this vaccine made from a protein produced by the patient's tumor. There is no guarantee or promise that this procedure will be successful
RATIONALE: Antifungal therapy with liposomal nystatin may reduce fever and neutropenia in patients undergoing treatment for hematologic cancer. It is not yet known whether liposomal nystatin is more effective than standard amphotericin B in treating patients with fever and neutropenia who are receiving chemotherapy for hematologic cancer or bone marrow transplantation for leukemia. PURPOSE: Randomized phase III trial to study the effectiveness of liposomal nystatin compared with standard amphotericin B to treat fever and neutropenia in patients receiving chemotherapy for hematologic cancer or bone marrow transplantation for leukemia.
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells. It is not yet known which combination chemotherapy regimen is most effective in treating patients with multiple myeloma. PURPOSE: Randomized phase III trial to compare the effectiveness of various combination chemotherapy regimens in treating patients with multiple myeloma.
RATIONALE: Reducing the amount of drugs used to prevent transplant rejection may help a person's body kill tumor cells. Giving biological therapy, such as interferon alfa, which may interfere with the growth of cancer cells, or combination chemotherapy, which uses different ways to stop tumor cells from dividing so they stop growing or die, may kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of reducing immunosuppression, and giving interferon alfa and combination chemotherapy, in treating patients who have malignant tumors that develop after organ transplant.
RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. PURPOSE: Phase II trial to study the effectiveness of suramin in treating patients who have refractory or relapsed multiple myeloma or Castleman's disease.
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage tumor cells. Combining peripheral stem cell transplantation with chemotherapy and radiation therapy may allow the doctor to give higher doses of radiation and chemotherapy drugs and kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of high-dose melphalan plus total-body irradiation and peripheral stem cell transplantation in treating patients with multiple myeloma in first relapse.
