Cyclophosphamide Treatment Options in Maryland

RATIONALE: Drugs used in chemotherapy, such as clofarabine and cyclophosphamide, 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) may kill more cancer cells. PURPOSE: This phase I trial is studying the side effects and best dose of clofarabine and cyclophosphamide in treating patients with relapsed or refractory acute leukemia, chronic myelogenous leukemia, or myeloproliferative disorders.

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Umbilical cord blood transplantation may be able to replace immune cells that were destroyed by the chemotherapy or radiation therapy that was used to kill cancer cells. PURPOSE: Phase II trial to study the effectiveness of umbilical cord blood transplantation plus combination chemotherapy in treating patients who have hematologic cancer or nonmalignant hematologic disease.

RATIONALE: Giving low doses of chemotherapy, such as fludarabine, and radiation therapy before a donor bone marrow or stem cell transplant helps stop the growth of cancer cells. It also stops the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune system 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 cyclophosphamide, mycophenolate mofetil, and tacrolimus after transplant may stop this from happening. PURPOSE: This phase I trial is studying cyclophosphamide and/or mycophenolate mofetil with or without tacrolimus to see which is the best regimen in treating patients who are undergoing a donor bone marrow or stem cell transplant for hematologic cancer.

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. White blood cells from donors may be able to kill cancer cells in patients who have hematologic cancer that has recurred following bone marrow transplantation. PURPOSE: Phase I trial to study the effectiveness of combination chemotherapy plus infusion of donated white blood cells in treating patients who have hematologic cancer that has recurred after bone marrow transplantation.

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 if chemotherapy given before surgery is more effective with or without docetaxel given before or after surgery for breast cancer. PURPOSE: Randomized phase III trial to compare the effectiveness of chemotherapy using doxorubicin and cyclophosphamide with or without docetaxel in treating women who have stage II or stage III breast cancer.

Studies have shown that up to 26% of patients with systemic lupus erythematoses nephritis may suffer from membranous lupus nephropathy. The disease is characterized by high levels of protein in the urine and may eventually lead to kidney failure. This study will evaluate the effectiveness and toxic effects of immunosuppressive drug therapy in patients with membranous lupus nephropathy over a 12 month period. The major goal of this therapy is to decrease protein losses and ultimately prevent kidney failure. Patients enrolled in the study will undergo a routine history and physical examination. In addition, several diagnostic tests will be conducted including; chest x-ray ECG, blood and urine laboratory tests. Patients will be divided and grouped according to the severity of their disease as shown by kidney function. Each group will then randomly be subcategorized by different treatment plans. Each treatment plan will made up of immunosuppressive medications including prednisone, cyclophosphamide, cyclosporin A, and combinations of these drugs. Patients will receive the medications as directed by the study. The study will last 12 months and require patients to be admitted for two to five days before the study begins and once the study is completed. Patients will be followed as outpatients throughout the 12 month study. Read Less

This protocol is designed to test the feasibility of the administration of vincristine, adriamycin and cytoxan, alternating with the newly developed regimen ifosfamide VP-16 as well as the efficacy of this therapy in addition to radiotherapy in producing complete responses and disease-free survival in patients with Ewing's sarcoma, primitive sarcoma of bone, peripheral neuroepithelioma, and soft tissue sarcoma. This will not be a randomized study but will be comparable to the large data base of similar patients treated on successive Pediatric Branch studies. Read Less

This is a pilot feasibility trial of AC (Adriamycin, cyclophosphamide) chemotherapy with G-CSF (filgrastim) followed by infusional Taxol (paclitaxel) as adjuvant treatment for patients with high risk stage II and stage III breast cancer. Cycles will be 14 days in duration. After 3 fourteen day cycles of AC with filgrastim, patients will be treated with 3 fourteen day cycles of 96 hour infusional paclitaxel. The goal of this study will be to assess the toxicity and feasibility of administering dose-intensive AC chemotherapy followed by infusional paclitaxel in 14 day cycles. Read Less

Stage III patients may begin therapy prior to or following surgery. Patients with undrainable significant third space fluid collection (e.g., pleural effusions, ascites) are entered directly on Consolidation. Patients receive induction chemotherapy with methotrexate and fluorouracil every 2 weeks for 4 courses. Patients then receive two 3-week courses of consolidation therapy with cyclophosphamide, followed by daily granulocyte colony-stimulating factor until completion of leukapheresis. Patients next receive myeloablative doses of thiotepa followed by stem cell rescue and granulocyte colony-stimulating factor. After hematopoietic reconstitution, patients receive 24-hour infusions of paclitaxel every 3 weeks for 4 doses, followed by doxorubicin or vinblastine every 3 weeks for 4 doses. Patients are then evaluated for additional therapy (surgery, radiotherapy, or hormonal therapy) as appropriate. Patients are followed every 3 months for 1 year, then every 6 months. Read Less
