Cyclophosphamide Treatment Options in Washington, DC

RATIONALE: Surgery alone may be effective in treating children with neuroblastoma. PURPOSE: Phase III trial to study the effectiveness of surgery alone in treating children who have neuroblastoma. Read Less

RATIONALE: Drugs used in chemotherapy work in 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. Giving combination chemotherapy together with radiation therapy may kill more cancer cells. PURPOSE: This clinical trial is studying how well giving chemotherapy together with radiation therapy works in treating patients with acute lymphoblastic leukemia that has relapsed in the CNS and/or testes.

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 them in different ways may kill more cancer cells. It is not yet known which regimen of combination chemotherapy is more effective for acute lymphoblastic leukemia PURPOSE: Randomized phase III trial to compare different regimens of combination chemotherapy in treating children who have newly diagnosed acute lymphoblastic leukemia.

Scleroderma is a rare, long-term autoimmune disease in which normal tissue is replaced with dense, thick fibrous tissue. Normally, the immune system helps defend the body against disease and infection. In people with scleroderma, the immune system triggers fibroblast cells to produce too much of the protein collagen. The extra collagen becomes deposited in the skin and organs, causing hardening and thickening that is similar to the scarring process. Although scleroderma most often affects the skin, it also can affect other parts of the body, including the lungs, and in its most severe forms scleroderma can be life-threatening. Scleroderma-related interstitial lung disease is one example of a life-threatening scleroderma condition. In people with symptomatic scleroderma-related interstitial lung disease, scarring occurs in the delicate lung tissue, compromising lung function. The purpose of this study is to determine whether people with symptomatic scleroderma-related interstitial lung disease experience more respiratory benefits from treatment with a 2-year course of mycophenolate mofetil or treatment with a 1-year course of oral cyclophosphamide.

This pilot, phase II trial studies the side effects of giving bortezomib together with combination chemotherapy and to see how well it works in treating young patients with relapsed acute lymphoblastic leukemia or lymphoblastic lymphoma. Bortezomib 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 bortezomib together with combination chemotherapy may kill more cancer cells. Read Less

This study will develop a national cord blood bank for siblings of patients with hemoglobinopathies and thalassemia. Read Less

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Monoclonal antibodies such as rituximab can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. Peripheral stem cell transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more cancer cells. PURPOSE: Phase II trial to study the effectiveness of combining chemotherapy and rituximab with peripheral stem cell transplantation in treating patients who have mantle cell lymphoma. Read Less

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Monoclonal antibodies such as rituximab can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. Combining rituximab with combination chemotherapy may kill more cancer cells. PURPOSE: Phase II trial to study the effectiveness of combining rituximab with combination chemotherapy in treating patients who have previously untreated non-Hodgkin's lymphoma. 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 chemotherapy drug may kill more tumor cells. It is not yet known which combination chemotherapy regimen is most effective in treating aggressive non-Hodgkin's lymphoma. PURPOSE: Randomized phase II trial to compare the effectiveness of two combination chemotherapy regimens in treating patients who have previously untreated aggressive stage II, stage III, or stage IV non-Hodgkin's lymphoma. 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 untreated acute lymphoblastic leukemia. Read Less

RATIONALE: Peripheral blood stem cell transplant using stem cells from the patient or a donor may be able to replace immune cells that were destroyed by chemotherapy used to kill tumor cells. The donated stem cells may also help destroy any remaining cancer cells (graft-versus-tumor effect). PURPOSE: This phase II trial is studying how well autologous peripheral stem cell transplant followed by donor peripheral stem cell transplant works in treating patients with multiple myeloma.

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 and alternating regimens of chemotherapy in treating patients who have non-Hodgkin's lymphoma or acute lymphocytic leukemia.
