Genetically Modified Peripheral Blood Stem Cell Transplant in Treating Patients With HIV-Associated Non-Hodgkin or Hodgkin Lymphoma
Description

This clinical trial studies genetically modified peripheral blood stem cell transplant in treating patients with HIV-associated non-Hodgkin or Hodgkin lymphoma. Giving chemotherapy before a peripheral stem cell transplant stops the growth of cancer cells by stopping them from dividing or killing them. After treatment, stem cells are collected from the patient's blood and stored. More chemotherapy or radiation therapy is then given to prepare the bone marrow for the stem cell transplant. Laboratory-treated stem cells are then returned to the patient to replace the blood-forming cells that were destroyed by the chemotherapy and radiation therapy

EPOCH and Rituximab to Treat Non-Hodgkin's Lymphoma in Patients With HIV Infection
Description

Background: * Human immunodeficiency virus (HIV)-infected patients have a weakened immune system, and chemotherapy, which is used to treat lymphoma, probably causes further damage to the immune system. * Limiting the amount of immune damage due to chemotherapy might decrease the number of infections and the risk of developing cancer in the future in HIV-infected patients with non-Hodgkin's lymphoma. Objectives: * To determine whether reducing the total amount of chemotherapy using a specific combination of drugs called EPOCH-R (etoposide, doxorubicin, vincristine, cyclophosphamide and rituximab) will rid the body of lymphoma quickly while decreasing the risk of infections and future cancers. * To determine whether the lymphoma will remain undetectable for at least one year if treatment is stopped one cycle after the patient enters remission. Eligibility: -Patients with non-Hodgkin's lymphoma and HIV infection 4 years of age and older who have not been treated previously with rituximab or cytotoxic chemotherapy. Design: * Patients receive EPOCH-R in 3-week treatment cycles for at least three and no more than six cycles. * The lymphoma is evaluated using computed tomography (CT) and positron emission tomography (PET) scans at the end of treatment cycles 2 and 3. A bone marrow biopsy is repeated after cycle 2 if a biopsy was initially positive on screening for participation in the study. * Anti-HIV therapy is stopped before chemotherapy begins and is restarted when EPOCH-R treatment ends. * Patients are monitored for treatment response with blood tests and imaging scans at baseline, when treatment ends, 2 months after treatment ends and then every 3 to 6 months for a total of 24 months following chemotherapy.

Gene Therapy in HIV-Positive Patients With Non-Hodgkin's Lymphoma
Description

The purpose of this study is to see if it is safe and effective to use gene therapy to treat non-Hodgkin's lymphoma (NHL) in HIV-positive patients. Stem cell transplantation is a procedure used to treat NHL. Stem cells are very immature cells that develop to create all of the different types of blood cells. In this study, some of your stem cells will be treated with gene therapy, meaning the cells are treated with a virus that does not cause disease. Some cells will receive a virus that contains ribozymes, enzymes that may help fight HIV. Other cells will be treated with a virus that does not contain ribozymes to see how the virus works alone. Some cells will not be treated at all. Doctors would like to see whether giving patients stem cells with ribozymes can treat NHL and stop HIV from growing at the same time.

COMPLETED
A Pilot Study of Non-Hodgkin's Lymphoma: Chemotherapy and Blood Levels of Organochlorines
Description

Non-Hodgkin's lymphoma (NHL) is the third most rapidly increasing cancer in the United States. HIV-related NHL is responsible for some of the increase since the early 1980s. However, it cannot explain the steady increase in the incidence rates in earlier years, nor the entire increase shown recently. A possible role of environmental exposures is receiving attention. One possibility is that exposure to organochlorines (OCs) may be related to the occurrence of NHL. NCI is currently designing a large population-based case-control study to investigate this hypothesis further by analyzing OC levels in blood collected at the time of interview from cases of NHL and their matched controls. At the time of these interviews, cases in the main case-control study would most likely have already received chemotherapy. If chemotherapy changes the blood levels of OCs, this may lead to misclassification of exposure among cases and eventually to biased risk estimates. The purpose of this pilot study is to estimate the bias due to measuring the serum levels of OCs in cases during or after chemotherapy. Twenty newly diagnosed patients will be recruited for the study. From each patient, four consecutive blood samples, one prior to, two during, and one after chemotherapy, will be collected. Forty pairs of pre-existing cryopreserved serum samples (pre- and post-treatment) taken from the NHL patients who participated in an earlier NCI clinical study will also be included in this study. Samples will be assayed for OC levels. The results will be used to plan and to interpret another large case-control study (the main study).
