Cyclophosphamide Treatment Options in Delaware

This phase III trial studies the side effects of combination chemotherapy, 3-dimensional conformal radiation therapy, and an autologous peripheral blood stem cell transplant, and to see how well they work in treating young patients with atypical teratoid/rhabdoid tumor of the central nervous system. Giving high-dose chemotherapy before an autologous peripheral blood stem cell transplant stops the growth of cancer cells by stopping them from dividing or killing them. Giving colony-stimulating factors, such as G-CSF, helps stem cells move from the bone marrow to the blood so they can be collected and stored. Chemotherapy or radiation therapy is then given to prepare the bone marrow for the stem cell transplant. The stem cells are then returned to the patient to replace the blood-forming cells that were destroyed by the chemotherapy or radiation therapy. Read Less

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Giving combination chemotherapy after surgery may kill any tumor cells remaining following surgery. It is not yet known which regimen of combination chemotherapy is more effective in treating breast cancer with positive axillary lymph nodes. PURPOSE: Randomized phase III trial to compare the effectiveness of different regimens of combination chemotherapy in treating women who have undergone surgery for stage I, stage II, or stage IIIA breast cancer with positive axillary lymph nodes.

This randomized phase III trial is studying low-dose vincristine to see how well it works compared with high-dose vincristine when given together with different combination chemotherapy regimens in treating young patients with intermediate-risk relapsed B-cell acute lymphoblastic leukemia. Drugs used in chemotherapy work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) and giving the drugs in different ways and different doses may kill more cancer cells.. Read Less

RATIONALE: Monoclonal antibodies such as rituximab can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Colony-stimulating factors such as filgrastim may increase the numbers of immune cells found in bone marrow or peripheral blood and may help a person's immune system recover from the side effects of chemotherapy. Combining chemotherapy with rituximab and filgrastim may kill more cancer cells. PURPOSE: Phase II trial to study the effectiveness of combining rituximab with chemotherapy and filgrastim in treating patients who have Burkitt's lymphoma or Burkitt's leukemia. Read Less

RATIONALE: Drugs used in chemotherapy work in 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. It is not yet known which chemotherapy regimen combined with radiation therapy and/or surgery is more effective in treating Ewing's sarcoma or primitive neuroectodermal tumor. PURPOSE: Randomized phase III trial to compare the effectiveness of different chemotherapy regimens combined with radiation therapy and/or surgery in treating patients who have Ewing's sarcoma or primitive neuroectodermal tumor.

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Monoclonal antibodies such as gemtuzumab ozogamicin can locate cancer cells and either kill them or deliver cancer-killing substances to them without harming normal cells. Combining more than one drug or combining monoclonal antibody with chemotherapy may kill more cancer cells. It is not yet known which treatment regimen is more effective for acute myelogenous leukemia. PURPOSE: Randomized phase II trial to compare the effectiveness of three treatment regimens in treating patients who have relapsed or refractory acute myelogenous leukemia. Read Less

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 whether combining cyclophosphamide with fludarabine is more effective than fludarabine alone in treating chronic lymphocytic leukemia. PURPOSE: Randomized phase III trial to study the effectiveness of fludarabine with or without cyclophosphamide in treating patients who have chronic lymphocytic leukemia that has not been treated previously. Read Less

RATIONALE: Monoclonal antibodies, such as rituximab, can locate cancer cells and either kill them or deliver cancer-killing substances to them without harming normal cells. Drugs used in chemotherapy work in different ways to stop cancer cells from dividing so they stop growing or die. Combining rituximab with combination chemotherapy may kill more cancer cells. PURPOSE: This phase II trial is studying how well giving rituximab together with combination chemotherapy works in treating patients with newly diagnosed Waldenstrom's macroglobulinemia. Read Less

RATIONALE: Drugs used in chemotherapy, such as pentostatin, cyclophosphamide, and CAMPATH-1H work in different ways to stop cancer cells from dividing so they stop growing or die. Monoclonal antibodies, such as rituximab can locate cancer cells and either kill them or deliver cancer-killing substances to them without harming normal cells. Combining chemotherapy with monoclonal antibody therapy may kill more tumor cells. PURPOSE: This phase II trial is studying how well pentostatin, cyclophosphamide, rituximab, and CAMPATH-1H work in treating patients with relapsed or refractory B-cell chronic lymphocytic leukemia. Read Less

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage cancer cells. Combining more than one drug with radiation therapy may kill more cancer cells. It is not yet known which combination chemotherapy regimen is most effective in treating Hodgkin's lymphoma. PURPOSE: This randomized phase III trial is studying two different combination chemotherapy regimens and comparing how well they work, with or without radiation therapy, in treating patients with Hodgkin's lymphoma.

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 more effective for breast cancer. PURPOSE: Randomized phase III trial to compare the effectiveness of two combination chemotherapy regimens in treating women with breast cancer who have undergone surgery to remove the tumor.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. It is not yet known which regimen of chemotherapy is more effective for breast cancer. PURPOSE: Randomized phase III trial to compare the effectiveness of two different regimens of combination chemotherapy in treating women who have stage II or stage IIIA breast cancer that has spread to the lymph nodes.
