Active clinical trials for "Leukemia, Lymphoid"

The purpose of this study is to determine the side effects and antitumor response of patients with lymphoid malignancies to Deoxycoformycin (DCF)/Pentostatin.

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 fludarabine in treating patients who have chronic lymphocytic leukemia that has not been previously treated.

This phase II trial studies how well giving fludarabine phosphate, cyclophosphamide, tacrolimus, mycophenolate mofetil and total-body irradiation together with a donor bone marrow transplant works in treating patients with high-risk hematologic cancer. Giving low doses of chemotherapy, such as fludarabine phosphate and cyclophosphamide, and total-body irradiation before a donor bone marrow transplant helps stop the growth of cancer cells by stopping them from dividing or killing them. Giving cyclophosphamide after transplant may also stop the patient's immune system from rejecting the donor's bone marrow stem cells. The donated stem cells may replace the patient's immune system cells and help destroy any remaining cancer cells (graft-versus-tumor effect). Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving tacrolimus and mycophenolate mofetil after the transplant may stop this from happening

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Oblimersen may help fludarabine and cyclophosphamide kill more cancer cells by making them more sensitive to the drugs. It is not yet known if fludarabine and cyclophosphamide are more effective with or without oblimersen. PURPOSE: Randomized phase III trial to compare the effectiveness of fludarabine and cyclophosphamide with or without oblimersen in treating patients who have relapsed or refractory chronic lymphocytic leukemia.

This phase I/II trial studies whether a new kind of blood stem cell (bone marrow) transplant, that may be less toxic, is able to treat underlying blood cancer. Stem cells are "seed cells" necessary to make blood cells. Researchers want to see if using less radiation and less chemotherapy with new immune suppressing drugs will enable a stem cell transplant to work. Researchers are hoping to see a mixture of recipient and donor stem cells after transplant. This mixture of donor and recipient stem cells is called "mixed-chimerism". Researchers hope to see these donor cells eliminate tumor cells. This is called a "graft-versus-leukemia" response.

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Giving the drugs in different combinations may kill more cancer cells. Bone marrow transplantation allows the doctor to give higher doses of chemotherapy and kill more cancer cells. PURPOSE: Phase II trial to compare the effectiveness of combination chemotherapy with or without donor bone marrow transplantation in treating infants who have previously untreated acute lymphoblastic leukemia.

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining more than one drug may kill more cancer cells. PURPOSE: Phase I/II trial to study the effectiveness of combining UCN-01 with fludarabine in treating patients who have relapsed or refractory chronic lymphocytic leukemia or lymphocytic lymphoma.

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining more than one drug may kill more cancer cells. Bone marrow transplantation may allow the doctor to give higher doses of chemotherapy and kill more cancer cells. Radiation therapy uses high-energy x-rays to damage cancer cells. PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy, bone marrow transplantation, and radiation therapy in treating infants with acute lymphoblastic leukemia.

RATIONALE: Drugs used in chemotherapy work in different ways to stop cancer cells from dividing so they stop growing or die. Combining chemotherapy with allogeneic or autologous stem cell transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more cancer cells. It is not yet known whether stem cell transplantation is more effective than standard chemotherapy in treating acute lymphoblastic leukemia. PURPOSE: This randomized phase III trial is studying how well stem cell transplantation works compared to standard combination chemotherapy in treating patients with acute lymphoblastic leukemia in first remission.

The goal of this clinical research study is to learn if intensive chemotherapy, combined with imatinib mesylate (Gleevec, STI571) given for 8 courses over 6 months, followed by maintenance imatinib mesylate plus chemotherapy for 2 years, followed by imatinib mesylate indefinitely can improve Philadelphia-positive acute lymphoblastic leukemia. The safety of this treatment will also be studied.
