Cyclophosphamide Treatment Options in San Diego, CA

This phase II/III trial is studying the side effects and how well giving dasatinib together with combination chemotherapy works in treating young patients with newly diagnosed acute lymphoblastic leukemia (ALL). Dasatinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. 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 dasatinib together with combination chemotherapy may kill more cancer cells. Read Less

Patients will be asked to participate in this study because patients have been diagnosed with high-risk neuroblastoma, a common childhood cancer which has aggressive features. If left untreated, high-risk neuroblastoma is fatal. Children with high-risk neuroblastoma often respond to current available treatments, but there is a high risk that the cancer will return. This study will test the safety of giving standard induction treatment for high-risk neuroblastoma without one of the drugs commonly used to prevent side effects. Current treatment for high-risk neuroblastoma includes anti-cancer drugs (chemotherapy), surgery, radiation therapy and high-dose chemotherapy with hematopoietic stem cell rescue. Treatment takes about one year to complete and occurs in 3 phases: induction, consolidation, and maintenance. This study is limited to the induction phase of treatment. Induction therapy includes six chemotherapy drugs given in different combinations every 3 weeks for a total of 6 courses. For the past decade, induction chemotherapy has been followed by a drug called granulocyte colony stimulating factor (G-CSF, filgrastim, peg-filgrastim, Neupogen, or Neulasta) to prevent side effects from the chemotherapy. G-CSF is routinely given to patients with high risk neuroblastoma after chemotherapy to stimulate white blood cell production and shorten the time period when the absolute neutrophil count (ANC), a type of white blood cell, is low after chemotherapy. G-CSF is known to shorten the period of low ANC by approximately 3 days. When the ANC is lowest, a patient is most at risk of getting a bacterial infection. Recent lab experiments in mice have shown that neuroblastoma tumor cells may respond to G-CSF by growing faster and metastasizing (spreading to other parts of the body). There have been no clinical trials comparing the survival of children with high risk neuroblastoma with or without G-CSF. This clinical trial is the first step towards giving induction chemotherapy with less G-CSF. The goal of this study is to determine if it is safe to give induction chemotherapy to children with neuroblastoma without giving G-CSF routinely. Read Less

RATIONALE: Drugs used in chemotherapy, such as vincristine, irinotecan, ifosfamide, etoposide, doxorubicin, cyclophosphamide, and dactinomycin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving high-dose combination chemotherapy together with radiation therapy may kill more tumor cells. PURPOSE: This phase III trial is studying how well giving high-dose combination chemotherapy together with radiation therapy works in treating patients with newly diagnosed metastatic rhabdomyosarcoma or ectomesenchymoma.

This randomized phase III trial is studying tacrolimus, methotrexate, and sirolimus to see how well they work compared to tacrolimus and methotrexate in preventing graft-versus-host disease in young patients who are undergoing donor stem cell transplant for intermediate-risk or high-risk acute lymphoblastic leukemia in second complete remission and high risk acute lymphoblastic leukemia in first remission. Giving chemotherapy, such as thiotepa and cyclophosphamide, and total-body irradiation before a donor stem cell transplant helps stop the growth of cancer cells. It also helps 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). Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving tacrolimus, methotrexate, and sirolimus after the transplant may stop this from happening. It is not yet known whether tacrolimus and methotrexate are more effective with or without sirolimus in preventing graft-versus-host disease. Read Less

RATIONALE: Specialized radiation therapy that delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Giving chemotherapy before surgery may shrink the tumor so that it can be removed during surgery. PURPOSE: Phase II trial to determine the effectiveness of specialized radiation therapy either alone or after chemotherapy and second surgery in treating children who have undergone surgery for localized ependymoma.

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. It is not yet known which regimen of combination chemotherapy is most effective for lymphoblastic lymphoma. PURPOSE: This randomized phase III trial is studying different regimens of combination chemotherapy to compare how well they work in treating children or adolescents with newly diagnosed stage III or stage IV lymphoblastic lymphoma.

This randomized phase II trial studies how well giving busulfan, cyclophosphamide, and melphalan or busulfan and fludarabine phosphate before donor hematopoietic cell transplant works in treating younger patients with juvenile myelomonocytic leukemia. Giving chemotherapy before a donor hematopoietic transplant helps stop the growth of cancer cells. It may also stop the patient's immune system from rejecting the donor's stem cells. When the healthy stem cells from a donor are infused into the patient, they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. It is not yet known whether giving busulfan, cyclophosphamide, and melphalan or busulfan and fludarabine phosphate before a donor stem cell transplant is more effective in treating juvenile myelomonocytic leukemia.

The primary objective of the study is to compare the complete response (CR) rate of bendamustine and rituximab (BR) with that of standard treatment regimens of either rituximab, cyclophosphamide, vincristine, and prednisone (R-CVP) or rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) in patients with advanced, indolent non-Hodgkin's lymphoma (NHL) or mantle cell lymphoma (MCL).

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. Giving more than one drug (combination chemotherapy) may kill more tumor cells. Monoclonal antibodies, such as bevacizumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Bevacizumab may also stop the growth of breast cancer by blocking blood flow to the tumor. Giving chemotherapy and bevacizumab before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. Giving bevacizumab after surgery may kill any tumor cells that remain after surgery. It is not yet known which chemotherapy regimen is more effective with or without bevacizumab in treating breast cancer. PURPOSE: This randomized phase III trial is studying six different chemotherapy regimens to compare how well they work with or without bevacizumab in treating women with stage I, stage II, or stage IIIA breast cancer that can be removed by surgery.
