Cyclophosphamide Treatment Options in Houston, TX

The goal of this clinical research study is to find the highest tolerable dose of the drugs clofarabine and cyclophosphamide that can be given together in the treatment of relapsed or refractory ALL. The safety of the combination treatment will also be studied. Objectives: Phase I: 1. To establish toxicities and safety of the proposed combination 2. To establish the dose-limiting toxicity (DLT) and maximum tolerated dose (MTD) of the combination to proceed with the phase II part of the study Phase II: 3. To establish the efficacy (complete and overall response) of the proposed combination. 4. To analyze pharmacokinetic (PK) and pharmacodynamic (PD) properties of clofarabine as well as the impact on DNA repair of leukemic blasts with the proposed combination. Read Less

The goal of this clinical research study is to learn the relationship of high-dose chemotherapy (HDCT) and circulating tumor cells (CTCs) in controlling metastatic breast cancer. The study also will investigate the role of CTCs in breast cancer. Read Less

Primary Objectives: 1. To compare the overall survival of metastatic renal cell carcinoma (RCC) patients undergoing HLA-matched related donor nonmyeloablative allogeneic hematopoietic stem cell transplantation (NST) using fludarabine-melphalan (FM) versus fludarabine-cyclophosphamide (FC) conditioning regimen. 2. To assess both cytotoxic T lymphocyte reactivity and antibodies activity against potential tumor antigenic peptides involved in graft-versus-RCC effect. Secondary Objectives: 1. To study the patient characteristics of metastatic RCC patients who undergo NST and those who do not undergo NST. 2. To compare the incidence of Day-100 treatment-related mortality in FM group and FC group. Read Less

Phase I trial to study the effectiveness of tirapazamine plus cyclophosphamide in treating children who have refractory solid tumors. 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. Read Less

Phase II trial to study the effectiveness of combination chemotherapy in treating patients with newly diagnosed metastatic Ewing's sarcoma or primitive neuroectodermal tumor. 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. Read Less

Phase II trial to study the effectiveness of radiation therapy following chemotherapy in treating children with CNS relapse from acute lymphoblastic leukemia. Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining chemotherapy with radiation therapy may kill more cancer cells. Read Less

Primary Objective: 1. Evaluate the ability of Cyclophosphamide, Fludarabine, Alemtuzumab, and Rituximab (CFAR) to increase the proportion of patients with \<5% CD5/CD19+ cells in bone marrow to 66% following 3 courses of treatment without significantly increasing the incidence of pneumonia or sepsis compared to a historic group of patients treated with the combination fludarabine, cyclophosphamide, and rituximab (FCR). Second Objectives: 1. Assess complete remission (CR), nodular partial remission (nPR), and partial remission (PR) rates (overall response) in high-risk, previously untreated patients with CLL treated with CFAR. 2. Evaluate molecular remission in bone marrow by polymerase chain reaction (PCR) for the clonal immunoglobulin heavy chain variable gene in responders treated with CFAR. 3. Assess immune parameters including blood T cell counts and subset distribution and serum immunoglobulin levels pretreatment, during treatment, and post-treatment in patients treated with CFAR.

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 combination chemotherapy consisting of doxorubicin, cyclophosphamide, and docetaxel in treating women with stage IIIB or stage IV breast cancer. Read Less

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining chemotherapy and radiation therapy with peripheral stem cell transplantation may allow the doctor to give higher doses of chemotherapy or radiation therapy and kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of chemotherapy with topotecan, cyclophosphamide, cisplatin, and vincristine plus radiation therapy and peripheral stem cell transplantation in treating children with newly diagnosed medulloblastoma or supratentorial primitive neuroectodermal tumor.

The purpose of this study is to compare the effectiveness of two multi-agent chemotherapy regimens using different dosages of cytarabine to eliminate all detectable leukemia. Read Less

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining peripheral stem cell transplantation with chemotherapy may kill more tumor cells. PURPOSE: Phase I/II trial to study the effectiveness of high-dose combination chemotherapy and peripheral stem cell transplantation in treating patients with recurrent or metastatic breast cancer. Read Less

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 and kill more cancer cells. PURPOSE: Phase I/II trial to study the effectiveness of combination chemotherapy plus peripheral stem cell transplantation in treating patients with refractory chronic lymphocytic leukemia. Read Less
