Cyclophosphamide Treatment Options in Texas

This phase II/III trial is studying the side effects and how well giving dasatinib together with combination chemotherapy works in treating young patients with newly diagnosed acute lymphoblastic leukemia (ALL). Dasatinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving dasatinib together with combination chemotherapy may kill more cancer cells. Read Less

Any time the words "you," "your," "I," or "me" appear, it is meant to apply to the potential participant. The goal of this clinical research study is to learn if thiotepa, busulfan, and clofarabine, when given before an allogeneic (bone marrow , blood, or cord blood cells) or haploidentical (bone marrow) stem cell transplantation can help to control cancers of the bone marrow and lymph node system. The safety of this treatment will also be studied. This is an investigational study. Thiotepa and clofarabine are FDA approved and commercially available for the treatment of leukemia. Busulfan is FDA approved and commercially available for use in stem cell transplantation. The combination of thiotepa, clofarabine, and busulfan together with a stem cell transplant is investigational. Up to 60 participants will take part in this study. All will be enrolled at M. D. Anderson. Read Less

High-risk neuroblastoma is an aggressive childhood cancer that shows up as a lump or mass in the belly or around the spinal cord in the chest, neck, or pelvis. Often the tumor has spread around the body to the bones or to the soft center of the bone, called the bone marrow. High-risk neuroblastoma often responds to treatment at first, but it frequently comes back and may be even more difficult to treat. Chemotherapy (drug treatments for cancer) is usually given at high doses in short bursts (3 to 5 days) followed by a few weeks of rest and recovery. This burst and recovery is called a "cycle" and usually takes about 21 days. Some scientists and physicians have tried to give chemotherapy at lower doses for more days, called "metronomic" chemotherapy. This method of giving chemotherapy has been used to treat neuroblastoma that has failed more standard types of treatment (relapsed neuroblastoma) and has shown some promise for those patients. One of the reasons it may work is by killing the blood vessels that feed the tumor as well as killing tumor cells themselves (the way that burst chemotherapy works). We think that giving a burst of chemotherapy together with metronomic therapy may kill the tumor while decreasing the side effects that we have seen in the past. Treatment for high risk neuroblastoma usually occurs in 3 stages: induction, consolidation, and maintenance. During the induction phase, patients will receive chemotherapy and possibly more surgery to get rid of most of the tumor cells. Most of the chemotherapy drugs during induction will be given in the standard burst method. One of the chemotherapy drugs, etoposide, will be given in lower, metronomic doses. The doctors will study how the tumors respond and the side effects patients have. After induction most childrens' tumors will have disappeared, also called remission. These children will receive the second stage of treatment called consolidation. During this stage, subjects will receive radiation treatments to the tumor and then higher doses of chemotherapy. Because of the side effects of the high doses of chemotherapy, we will collect and store some special blood cells (called hematopoietic stem cells) early in treatment and keep them frozen. After the high doses of chemotherapy, these cells will be thawed and given to the subject. . This is called hematopoietic stem cell transplant (HSCT). The final stage of treatment, called maintenance, consists of a drug taken by mouth for 6 months. Surgery to remove large, or bulky, tumors is a standard part of treatment for high risk neuroblastoma. A few children can have their main tumor removed before chemotherapy, but most require the tumor to shrink first. Surgery has usually been scheduled for after 3 to 5 cycles of therapy, but no one really knows how quickly the tumors are ready to come out. Because chemotherapy has significant side effects that can change the risks of surgery, we will study how early surgeries to remove tumors can happen. This study is being done to evaluate the outcomes of disease response and survival in children with high risk neuroblastoma treated on this regimen. Read Less

The goal of this clinical research study is to learn about the safety of giving a stem cell transplant from a tissue-mismatched donor, followed by cyclophosphamide, to patients with certain types of blood disorders or blood cancers. Melphalan, thiotepa, and fludarabine will also be given before the transplant. Researchers will study the health status of these patients at 3 months after the transplant. Read Less

Patients will be asked to participate in this study because patients have been diagnosed with high-risk neuroblastoma, a common childhood cancer which has aggressive features. If left untreated, high-risk neuroblastoma is fatal. Children with high-risk neuroblastoma often respond to current available treatments, but there is a high risk that the cancer will return. This study will test the safety of giving standard induction treatment for high-risk neuroblastoma without one of the drugs commonly used to prevent side effects. Current treatment for high-risk neuroblastoma includes anti-cancer drugs (chemotherapy), surgery, radiation therapy and high-dose chemotherapy with hematopoietic stem cell rescue. Treatment takes about one year to complete and occurs in 3 phases: induction, consolidation, and maintenance. This study is limited to the induction phase of treatment. Induction therapy includes six chemotherapy drugs given in different combinations every 3 weeks for a total of 6 courses. For the past decade, induction chemotherapy has been followed by a drug called granulocyte colony stimulating factor (G-CSF, filgrastim, peg-filgrastim, Neupogen, or Neulasta) to prevent side effects from the chemotherapy. G-CSF is routinely given to patients with high risk neuroblastoma after chemotherapy to stimulate white blood cell production and shorten the time period when the absolute neutrophil count (ANC), a type of white blood cell, is low after chemotherapy. G-CSF is known to shorten the period of low ANC by approximately 3 days. When the ANC is lowest, a patient is most at risk of getting a bacterial infection. Recent lab experiments in mice have shown that neuroblastoma tumor cells may respond to G-CSF by growing faster and metastasizing (spreading to other parts of the body). There have been no clinical trials comparing the survival of children with high risk neuroblastoma with or without G-CSF. This clinical trial is the first step towards giving induction chemotherapy with less G-CSF. The goal of this study is to determine if it is safe to give induction chemotherapy to children with neuroblastoma without giving G-CSF routinely. Read Less

Study of ONTAK and CHOP (chemotherapy drugs) to find out their ability to make Peripheral T-cell lymphoma disappear (for any period of time) and potentially lengthen life. The study will also compare what kind of side effects these drugs cause and how often they occur. The hypothesis is that patients with newly diagnosed peripheral T-Cell lymphoma, when given ONTAK + CHOP, will tolerate the treatment and will have a 20% improvement in response rate when compared to CHOP alone.

To determine the prognostic relevance of histological atypia and SV40 in choroid plexus tumors. Read Less

This phase I trial studies the side effects and best way to give natural killer cells and donor umbilical cord blood transplant in treating patients with hematological malignancies. Giving chemotherapy with or without total body irradiation before a donor umbilical cord blood 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 and natural killer 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.
