Active clinical trials for "Neoplasms, Plasma Cell"

The objective of this protocol is to assess therapeutic activity of thalidomide in previously untreated patients with asymptomatic multiple myeloma.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining bone marrow transplantation with chemotherapy may allow doctors to give higher doses of chemotherapy and kill more tumor cells. PURPOSE: This phase II trial is studying the side effects of giving a bone marrow transplant together with chemotherapy and to see how well it works in treating patients with refractory non-Hodgkin's lymphoma, Hodgkin's lymphoma, or multiple myeloma.

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: Monoclonal antibodies can locate tumor cells and either kill them or deliver tumor-killing substances to them. PURPOSE: Phase II trial to study the effectiveness of the monoclonal antibody rituximab in treating patients with multiple myeloma that is newly diagnosed.

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining chemotherapy with peripheral stem cell transplant may allow the doctor to give higher doses of chemotherapy drugs and kill more cancer cells. PURPOSE: This phase II trial is studying how well chemotherapy and peripheral stem cell transplant work in treating patients with multiple myeloma or primary systemic amyloidosis.

RATIONALE: Thalidomide may stop the growth of multiple myeloma by stopping blood flow to the cancer cells. Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining thalidomide with chemotherapy may kill more cancer cells. PURPOSE: Phase II trial to study the effectiveness of thalidomide, doxorubicin, and dexamethasone in treating patients who have untreated stage II or stage III multiple myeloma.

RATIONALE: White blood cells from donors may be able to kill cancer cells in patients with cancer that has recurred following bone marrow or peripheral stem cell transplantation. PURPOSE: Phase II trial to study the effectiveness of donated white blood cells in treating patients who have relapsed cancer following transplantation of donated bone marrow or peripheral stem cells.

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining chemotherapy with peripheral stem cell transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more cancer cells. Sometimes the transplanted cells are rejected by the body's normal tissues. Antithymocyte globulin may prevent this from happening. PURPOSE: Phase II trial to study the effectiveness of chemotherapy plus biological therapy followed by peripheral stem cell transplantation in treating patients who have hematologic cancer.

RATIONALE: Interleukin-2 may stimulate a person's white blood cells to kill cancer cells. PURPOSE: Phase I trial to study the effectiveness of interleukin-2 following bone marrow transplantation in treating patients who have hematologic cancer at risk of relapse.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining chemotherapy with peripheral stem cell transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more tumor cells. PURPOSE: Phase I/II trial to study the effectiveness of combination chemotherapy plus peripheral stem cell transplantation in treating patients who have multiple myeloma.
