Cyclophosphamide Treatment Options in Texas

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining chemotherapy with peripheral stem cell transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more cancer cells. PURPOSE: Randomized phase III trial to compare the effectiveness of two regimens of combination chemotherapy in treating patients who have intermediate-grade or immunoblastic 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 different regimens of combination chemotherapy in treating patients with newly diagnosed mantle cell lymphoma. Read Less

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.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Colony-stimulating factors such as filgrastim may increase the number 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. Peripheral stem cell transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more tumor cells. It is not yet known which treatment regimen is more effective for breast cancer. PURPOSE: Randomized phase III trial to compare the effectiveness of chemotherapy plus filgrastim with filgrastim alone in treating women undergoing peripheral stem cell transplantation for stage II, stage III, or metastatic breast cancer.

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining chemotherapy with peripheral stem cell transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more cancer cells. PURPOSE: Phase I/II trial to study the effectiveness of high-dose chemotherapy plus peripheral stem cell transplantation in treating patients with chronic myelogenous or acute leukemia. Read Less

RATIONALE: Peripheral stem cell transplantation may be able to replace immune cells that were destroyed by the chemotherapy or radiation therapy used to kill tumor cells. Sometimes the transplanted cells are rejected by the body's normal tissues. Transplanting donated cells that have been treated with psoralen may prevent this from happening. PURPOSE: Phase I trial to study the effectiveness of chemotherapy, radiation therapy, and psoralen-treated donor cells in treating patients who are undergoing peripheral stem cell transplantation for hematologic cancer.

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. PURPOSE: Phase II trial to study the effectiveness of bone marrow transplantation in treating patients with chronic lymphocytic leukemia. Read Less

This study is for patients with chronic granulomatous disease (CGD), which is a disorder of the immune system that puts them at risk for severe infections. CGD is caused by a genetic defect that stops or prevents the white blood cells from killing certain bacteria and fungi. This condition cannot presently be cured by standard treatment with drugs or surgery. Medicine including antibiotics, antifungals, and interferon gamma, may help some patients with CGD; however even with continuous treatment, most patients with CGD will have chronic and recurrent infections. Transfusion of white blood cells may help overcome infection, but white cell transfusions lead to allergic reactions and fever and the benefit of transfusion lasts only a matter of hours. Ultimately, chronic infections can damage or injure the body organs. Injury to the lung or liver can lead to lung or liver failure and death. Medicines used to treat infection can damage body organs too. Infections may become resistant to antibiotic or antifungal treatment, and infections not responding to treatment can be deadly. It is now known that under specific conditions and with special treatment, blood stem cells (the cells that make blood) can be transplanted from one person to another. Stem cell transplantation has been done for patients with CGD who have a healthy sibling and who share the same immune type (HLA type) as the patient. Stem cell transplantation allows healthy or normal white cells from the stem cell donor to grow or develop in the patient's bone marrow. These healthy white cells can fight infection and prevent future infections for a patient with CGD. Patients on this study will receive stem cells from a related or unrelated donor. The donor will be closely matched to the patient's immune type but the donor is not a sibling. The reason this treatment is investigational is that we do not know the likelihood of benefit that the patient will receive. It is possible that they will have great benefit, like some of the patients who have been transplanted from a brother or sister. It is possible that the side-effects of treatment may be too severe so that the transplant won't work. The purpose of this research study is to evaluate whether or not patients with CGD treated with a stem cell transplant from a non-matched and/or non-related donor can have a good outcome from the procedure with an acceptable number of side-effects.

This randomized phase II trial studies how well giving bortezomib with or without combination chemotherapy works as consolidation therapy in patients with newly diagnosed multiple myeloma who have completed stem cell transplant. Bortezomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as cyclophosphamide, dexamethasone, and lenalidomide, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. It is not yet known whether giving bortezomib is more effective with or without combination chemotherapy in the post transplant setting. Read Less

RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. Drugs used in chemotherapy work in different ways to stop tumor cells from dividing so they stop growing or die. It is not yet known whether radiation therapy alone is as effective as chemotherapy plus radiation therapy in treating germ cell tumor. PURPOSE: This randomized phase III trial is studying radiation therapy alone to see how well it works compared to chemotherapy and radiation therapy in treating patients with newly diagnosed primary CNS germ cell tumor.

To determine the effect of weight on doxorubicin and cyclophosphamide plasma clearance in participants who are normal weight (body mass index \[BMI\] \< 25 kg/m2, overweight or class I obese (BMI 25-34.9 kg/m2), or class II-III obese (BMI ≥ 35 kg/m2). The hypothesis is that participants who weigh more will have higher doxorubicin and cyclophosphamide clearances than participants who weigh less. Restated, the area under the drug-concentration time profile, also known as the AUC, in participants will decrease as participant weight increases. Read Less
