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. Radiation therapy uses high-energy x-rays to damage cancer cells, and may be an effective treatment for lymphoma. Bone marrow transplantation may be able to replace immune cells that were destroyed by chemotherapy or radiation therapy used to kill cancer cells. PURPOSE: Phase II trial to study the effectiveness of bone marrow transplantation in treating patients with recurrent or residual low-grade lymphoma. Read Less

The purpose of this study is to evaluate the addition of Herceptin to standard chemotherapy treatment of patients newly diagnosed with operable breast cancer. Other objectives: 1) to evaluate the potential of this therapy to reduce the size of the tumor and increase the possibility of breast conservative surgery, 2) evaluate the ability of this regimen to prevent recurrence of breast cancer and impact on survival, 3) determine side effect profile with the addition of Herceptin, and 4) evaluate significance of HER2 expression by two different methods.

This is a Phase 1, open-label, single-center, dose-escalating study in pediatric patients with refractory or recurrent solid tumors. Patients will be registered into 1 of 2 strata, depending upon the presence bone marrow metastases or previous treatment with intensive myelosuppression therapy. Patients will receive Karenitecin along with cyclophosphamide daily for 5 consecutive days, every 21 days (1 treatment cycle). Treatment may continue for up to 20 cycles, as long as there is continued evidence of clinical benefit and an absence of unacceptable toxicity. Read Less

RATIONALE: Drugs used in chemotherapy use 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 radiation therapy to the head or intrathecal chemotherapy may prevent cancer cells from spreading to the brain. It is not yet known which treatment regimen is more effective for acute lymphoblastic leukemia. PURPOSE: Randomized phase III trial to compare the effectiveness of radiation therapy to the head or intrathecal chemotherapy plus high dose cytarabine in preventing CNS disease in children who have acute lymphoblastic leukemia.

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

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.

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

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

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

1. To determine the safety and efficacy of non-myeloablative allogeneic stem cell transplantation using rituximab, cyclophosphamide, fludarabine as a preparative regimen for patients with advanced or recurrent mantle cell lymphoma. 2. To determine factors associated with response and durable remission in patients receiving rituximab, cyclophosphamide, and fludarabine in preparation for allogeneic stem cell transplantation.

Objective of the low-dose transplant regimen must produce the following effects: 1. Suppression of the patient's immune system to prevent rejection of the donor cells; 2. Control of the lymphoma. The pretransplant regimen must suppress the lymphoma sufficiently to prevent marked progression of the tumor and allow time for the GVT effect to occur. Read Less
