Cyclophosphamide Treatment Options in Texas

RATIONALE: Seneca Valley virus-001 may be able to kill certain kinds of tumor cells without damaging normal cells. Adding low dose cyclophosphamide (in part B of study) may help to kill even more tumor cells. PURPOSE: This phase I trial is studying the side effects and best dose of Seneca Valley virus-001 in treating young patients with relapsed or refractory neuroblastoma, rhabdomyosarcoma, or rare tumors with neuroendocrine features.

RATIONALE: Monoclonal antibodies, such as rituximab and yttrium Y 90 ibritumomab tiuxetan, can locate cancer cells and either kill them or deliver radioactive cancer-killing substances to them without harming normal cells. Drugs used in chemotherapy, such as prednisone, cyclophosphamide, doxorubicin, and vincristine, use different ways to stop cancer cells from dividing so they stop growing or die. Combining monoclonal antibody therapy with chemotherapy may kill more cancer cells. PURPOSE: This phase II trial is studying how well giving rituximab and combination chemotherapy together with yttrium Y 90 ibritumomab tiuxetan works in treating patients with previously untreated mantle cell lymphoma.

To investigate the safety and efficacy of two dose regimes of ofatumumab in combination with chemotherapy in previously untreated patients with B-CLL Read Less

RATIONALE: Drugs used in chemotherapy work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. A bone marrow or peripheral stem cell transplant using stem cells from the patient may be able to replace blood-forming cells that were destroyed by chemotherapy. This may allow more chemotherapy to be given so that more tumor cells are killed. PURPOSE: This phase III trial is studying how well giving combination chemotherapy with or without etoposide followed by an autologous stem cell transplant works in treating young patients with previously untreated malignant brain tumors.

The purpose of this study is to evaluate the toxicity and the effectiveness of high dose chemotherapy with HPC transplant Multiple Sclerosis that has failed at least two lines of therapy Read Less

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 I trial to study the effect on the body of combining cyclophosphamide with cisplatin, etoposide, and bleomycin in treating children who have newly diagnosed malignant germ cell tumors that are not in the brain and gonads.

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining chemotherapy with bone marrow transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more cancer cells. Radiation therapy uses high-energy x-rays to damage cancer cells. Combining chemotherapy, radiation therapy, and bone marrow transplantation may kill more cancer cells. PURPOSE: Randomized phase III trial to compare high-dose chemotherapy with or without total-body irradiation before bone marrow transplantation in treating children with 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 and giving the drugs in different combinations may kill more cancer cells. PURPOSE: Randomized phase III trial to compare the effectiveness of standard combination chemotherapy treatment with more intensive combination chemotherapy in treating children with acute lymphocytic leukemia. Read Less

RATIONALE: Drugs used in chemotherapy, such as carboplatin and vincristine, 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. Combining carboplatin and vincristine with radiation therapy followed by adjuvant chemotherapy may kill more tumor cells. PURPOSE: Randomized phase II trial to study the effectiveness of combination chemotherapy plus radiation therapy followed adjuvant chemotherapy in treating young patients who have newly diagnosed high-risk CNS embryonal tumors. 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. PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy in treating patients who have non-Hodgkin's lymphoma or acute lymphocytic leukemia. Read Less

The purposes of this study are: 1. To find the highest dose of monthly intravenous Zometa that can be given with daily low doses of cyclophosphamide by mouth to children with recurrent or refractory neuroblastoma without causing severe side effects. 2. To find out the side effects seen by giving Zometa and cyclophosphamide on this schedule at different dose levels. 3. To measure blood and urine levels of Zometa during treatment 4. To preliminarily evaluate the antitumor activity of Zometa and concomitant oral cyclophosphamide in children with recurrent and/or refractory neuroblastoma within the confines of a Phase I study. 5. To measure the effects of Zometa on markers of bone breakdown found in urine, blood, and bone marrow 6. To measure the effects of Zometa on the immune system. Read Less

RATIONALE: Bone marrow that has been treated to remove certain white blood cells may reduce the chance of developing graft-versus-host disease following bone marrow transplantation. PURPOSE: Randomized phase II/III trial to compare the effectiveness of treated bone marrow with that of untreated bone marrow in preventing graft-versus-host disease in patients with acute or chronic leukemia who are undergoing bone marrow transplantation.
