Cyclophosphamide Clinical Trials

RATIONALE: Donor peripheral stem cell transplantation may be able to replace bone marrow and immune cells that were destroyed by chemotherapy. Sometimes the transplanted cells from a donor are rejected by the body's normal cells. Eliminating the T cells from the donor cells before transplanting them and giving cyclosporine may prevent this from happening. PURPOSE: This phase I trial is studying the side effects of T-cell-depleted allogeneic stem cell transplantation after immunoablative induction chemotherapy and reduced-intensity transplantation conditioning (chemotherapy) in treating patients with hematologic malignancies.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor 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 tumor cells. PURPOSE: Phase II trial to study the effectiveness of high-dose chemotherapy and peripheral stem cell transplantation in treating patients with recurrent or refractory metastatic breast cancer.

The goal of this clinical research study is to learn if the combination of fludarabine, cyclophosphamide, alemtuzumab, and rituximab is effective in treating chronic lymphocytic leukemia in patients who have already been treated with chemotherapy. Primary Objectives: Evaluate the therapeutic efficacy, including the complete remission (CR), nodular partial remission (NPR), and partial remission (PR) rates (overall response) of combined cyclophosphamide, fludarabine, alemtuzumab, and rituximab (CFAR) in previously treated patients with Chronic Lymphocytic Leukemia (CLL). Second Objectives: * Assess the toxicity profile of CFAR in previously treated patients with CLL. * Monitor for infection and determine incidence and etiology of infection including cytomegalovirus in patients treated with CFAR. * Evaluate molecular remission by polymerase chain reaction (PCR) for the clonal immunoglobulin heavy chain variable gene in responding patients treated with CFAR. * Assess immune parameters, including pretreatment, during treatment, and post-treatment blood T-cell counts and subset distribution and serum immunoglobulin levels in patients treated with CFAR.

The goal of this clinical research study is to learn if a special combination of chemotherapy drugs called "augmented hyper-CVAD chemotherapy" given over 6 to 8 months followed by monthly maintenance chemotherapy for one year can help to control acute lymphoblastic leukemia or lymphoblastic lymphoma. The safety of this therapy will also be studied. 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 II trial to study the effectiveness of two treatment regimens for patients in developing countries with diffuse non-Hodgkin's lymphoma and acute lymphoblastic leukemia. Read Less

Primary Objectives: 1. To prospectively evaluate the predictive accuracy of a previously discovered gene expression profile-based test to foretell pathologic complete response (pCR) to preoperative paclitaxel/FAC (5-fluorouracil, doxorubicin, cyclophosphamide) chemotherapy for stage I-III breast cancer. 2. To evaluate if our genomic predictive test is specific to the paclitaxel/FAC regimen or it also predicts increased sensitivity to FAC only chemotherapy. Secondary Objectives: 1. To discover a molecular profile that is associated with pCR after FAC chemotherapy alone 2. To establish a prospectively collected gene expression profile data bank of breast cancer for future studies 3. To compare the pCR rates between patients who receive 6 courses FAC and those who receive sequential paclitaxel /FAC chemotherapies. Read Less

We are asking you to take part in a research study of biomarkers (characteristics or traits of the genes inside cancer cells). We want to learn if these biomarkers could help us learn how well your breast cancer may respond (improve) to chemotherapy (drugs to treat cancer). Read Less

RATIONALE: Aldesleukin may stimulate lymphocytes to kill melanoma cells. Treating lymphocytes with interleukin-21 in the laboratory may help the lymphocytes kill more tumor cells when they are put back in the body. Giving therapeutic autologous lymphocytes together with cyclophosphamide and aldesleukin may kill more tumor cells. PURPOSE: This phase I trial is studying the side effects and best dose of giving therapeutic autologous lymphocytes together with cyclophosphamide and aldesleukin in treating patients with metastatic melanoma Read Less

Primary Objective: 1. To determine the maximally tolerated dose of anti-third party cytolytic T-lymphocytes, defined as the dose which achieve engraftment without severe GVHD (graft-vs-host disease) at 90 days after allogeneic transplantation of CD34+ hematopoietic progenitor cells. Secondary Objective: 1. Toxicity, response rate, time to progression and overall survival. Read Less

RATIONALE: Bone marrow transplantation may be able to replace immune cells that were destroyed by chemotherapy and radiation therapy used to kill tumor cells. PURPOSE: Phase II trial to study the effectiveness of bone marrow transplantation in treating patients who have hematologic cancer. Read Less

RATIONALE: Drugs used in chemotherapy use 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. Bone marrow transplantation may be able to replace immune cells that were destroyed by chemotherapy or radiation therapy used to kill tumor cells. PURPOSE: Phase II trial to study the effectiveness of bone marrow transplantation using unrelated bone marrow donors in treating patients who have hematologic cancer. Read Less

Primary Objectives: 1. To evaluate the role of autologous and allogenic stem cell transplantation with Campath-1H for patients with peripheral T-cell lymphoma (PTCL). 2. To examine the impact of in-vivo purging with Campath -1H pre-autologous stem transplantation for patients with PTCL. 3. To evaluate the impact of soluble CD52 upon in-vivo purging with Campath-1H. 4. To evaluate the role of Campath -1H in the treatment minimal residual disease after autologous transplantation for PTCL. Read Less
