Active clinical trials for "Precursor Cell Lymphoblastic Leukemia-Lymphoma"

The reason for doing this study is to determine whether a new method of blood stem cell transplant (also known as bone marrow transplant) is able to treat acute lymphocytic leukemia. Blood stem cells are the "seed cells" necessary to make all blood cells. This new method of transplant uses a combination of low dose radiation and chemotherapy that may be less toxic and cause less harm than a conventional transplant. This lower dose transplant is called a "nonmyeloablative transplant". Researchers want to see if using less radiation and less chemotherapy combined with new immune suppressing drugs after the transplant will help a stem cell transplant to work. Researchers hope that this treatment will cure acute lymphocytic leukemia with fewer side effects. Researchers are hoping to see a mixture of recipient and donor blood cells after transplant. This mixture of donor and recipient blood cells is called "mixed chimerism". Researchers hope that donor cells will attack and eliminate the leukemia. This is called the "graft-versus-leukemia" effect. In addition, after the transplant, white blood cells from the donor may be given to enhance or "boost" the graft-versus-leukemia effect, and hopefully remove all remaining cancer cells. This study is being done because at the present time blood stem cell transplantation (or bone marrow transplantation) is the only known curative therapy for acute lymphocytic leukemia. Because of age or underlying health status acute lymphocytic leukemia patients have a higher likelihood of experiencing severe harm from a conventional blood stem cell transplant. Researchers are doing this study to see if this new nonmyeloablative method of low dose radiation and low dose chemotherapy given before transplant and immune suppressive drugs after transplant will help make the transplant safer and also cure acute lymphocytic leukemia

This phase I trial is studying the side effects and best dose of FR901228 in treating children with refractory or recurrent solid tumors or leukemia. Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die

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. It is not yet known which regimen of chemotherapy is more effective for acute lymphoblastic leukemia. PURPOSE: This randomized phase III trial is comparing four regimens of combination chemotherapy to see how well they work in treating children with newly diagnosed acute lymphoblastic leukemia.

RATIONALE: Radiation therapy uses high-energy x-rays to damage cancer cells. Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Peripheral stem cell transplantation may allow doctors to give higher doses of chemotherapy drugs and kill more cancer cells. PURPOSE: Phase I/II trial to study the effectiveness of radiation therapy and chemotherapy plus peripheral stem cell transplantation in treating patients who have high-grade lymphoma or acute lymphoblastic leukemia.

This clinical trial studies fludarabine phosphate, low-dose total body irradiation, and donor stem cell transplant in treating patients with hematologic malignancies or kidney cancer. Giving chemotherapy drugs, such as fludarabine phosphate, and total-body irradiation before a donor peripheral blood stem cell transplant helps stop the growth of cancer cells. It may also stop the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune cells and help destroy any remaining cancer cells (graft-versus-tumor effect). Giving an infusion of the donor's T cells (donor lymphocyte infusion) after the transplant may help increase this effect. Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving cyclosporine before the transplant and cyclosporine and mycophenolate mofetil after the transplant may stop this from happening.

Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. This phase II trial is studying how well topotecan hydrochloride works in treating children with meningeal cancer that has not responded to previous treatment

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Peripheral stem cell transplantation may be able to replace immune cells that were destroyed by chemotherapy and radiation therapy. Sometimes the transplanted cells are rejected by the body's normal tissues. Mycophenolate mofetil and donor white blood cells may prevent this from happening. PURPOSE: Phase I/II trial to determine the effectiveness of combination chemotherapy and total-body irradiation followed by peripheral stem cell transplantation in treating patients who have acute lymphoblastic 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. PURPOSE: Phase II trial to study the effectiveness of two treatment regimens for patients in developing countries with diffuse non-Hodgkin's lymphoma and acute lymphoblastic leukemia.

This phase I trial is studying how well ipilimumab works after allogeneic stem cell transplant in treating patients with persistent or progressive cancer. Monoclonal antibodies can locate cancer cells and either kill them or deliver cancer-killing substances to them without harming normal cells.

This phase I/II trial is studying the side effects of biological therapy and to see how well it works in treating patients with advanced myelodysplastic syndrome, chronic myeloid leukemia, acute myeloid leukemia, or acute lymphoblastic leukemia. Biological therapies, including immunotherapy, can potentially be used to stimulate the immune system and stop cancer cells from growing. Immunotherapy given to patients who have undergone donor stem cell transplantation may be a way to eradicate remaining cancer cells
