Filter by:Background: - This protocol acknowledges that it is in the interest of the NIH and ROB, as well as our patients, to continue to follow those who have been treated with radiotherapy at ROB and are not otherwise eligible for current active research protocols. - It also provides a mechanism for the correlation and interpretation of disparate data for research into the long term side effects and outcomes for a variety of disease entities and treatments, such as combined modality treatment, MoAb, PDT, radiation modifiers, intraoperative radiotherapy, etc. Objective: -The primary objective of this protocol is to assess the late effects of treatment and the natural history of disease through collection of data from any standard procedures performed as part of follow up care on patients previously treated with radiotherapy in the Radiation Oncology Branch (ROB). Eligibility: -Patients who received radiation therapy at the NCI and are not entered on an interventional research protocol at the time of enrollment. Design: - This is a natural history protocol in which data will be collected from Radiation Oncology Branch patients receiving standard of care long-term follow up care and evaluation, including NIH consultation services as required. - It will be made clear to patients in the consent form, that data collected during their follow-up may be used anonymously for publications concerning the natural history of disease processes and long-term effects of treatment.
Butadiene is a suspect human carcinogen to which most people are exposed daily. Exposures are difficult to measure by air sampling. This study examines the relationship between air levels and several biomarkers of exposure. Biomarkers are substances analyzed in human tissues or waste products. Adducts are materials formed when a chemical reacts with a biological material. In this study we are looking at biomarkers in the blood: hemoglobin and DNA adducts, and urinary metabolites. If a strong relationship is found then the amounts of biomarkers in a person's blood or urine can tell us how much they have been exposed. The tests are being conducted on petrochemical workers who have a wide range of exposures to butadiene. An international group of investigators is conducting the study.
RATIONALE: MS-275 may stop the growth of cancer cells by blocking the enzymes necessary for their growth. PURPOSE: This phase I trial is studying the side effects and best dose of MS-275 in treating patients with advanced solid tumors or lymphoma.
RATIONALE: Antiemetic drugs may help to reduce or prevent vomiting in patients treated with radiation therapy. It is not yet known if ondansetron is more effective with or without dexamethasone in preventing vomiting caused by radiation therapy. PURPOSE: This randomized phase III trial is comparing how well ondansetron works with or without dexamethasone in preventing vomiting in patients with cancer who are receiving radiation therapy to the upper abdomen.
This project is designed to establish whether pesticides or other environmental agents have a role in the excess birth defects identified in the Red River Valley of Minnesota. In this human study, laboratory based health parameters will be used to key in health survey data. In vitro data will be developed to mechanistic information. Concordant results among these study features will provide a weight of evidence approach.
Hematotoxicity is caused by a number of agents such as a benzene by-product called hydroquinone and the antitumor agent doxorubicin. This is a basic research study, conducted using normal human donors, of mechanisms involved in hematotoxicity and of the protective response of human hematopoietic progenitor cells to hematotoxic agents. Tumor necrosis factor exposure protects these cells from a subsequent exposure to hematotoxic agents. The alteration of gene expression in these cells caused by tumor necrosis factor is being studied. Additionally, the tumor necrosis factor-induced biochemical pathways involved in protection of human hematopoietic progenitor cells will be studied.
This study compares air pollution exposures of residents in a South Baltimore community next to major industry with those in a comparison community with much less industry nearby. Parents and children as well as adults alone will be included. Air levels of 3 chemicals that have been found in increased amounts in the community as well as two urinary breakdown products of benzene will be measured. Participants will limit the amount of sorbate preserved foods they eat as this preservative interferes with one of the benzene breakdown products. Benzene air and urine exposure measurements will be compared in each community as well as between communities. By including children and parents we will gather exposure information on children who may be more sensitive that adults to these types of pollution. Lastly, by restricting the amount of food preserved with sorbates, we can decide if this improves the use of ttMA for people exposed to benzene from air pollution.
RATIONALE: Antivirals such as ribavirin are used to treat infections caused by viruses. It is not yet known if ribavirin is more effective with or without monoclonal antibody therapy in treating patients who develop RSV pneumonia following peripheral stem cell transplantation. PURPOSE: Randomized phase III trial to compare the effectiveness of ribavirin with or without monoclonal antibody in treating patients who develop RSV pneumonia following peripheral stem cell transplantation.
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one chemotherapy drug may kill more tumor cells. PURPOSE: Phase I trial to study the effectiveness of capecitabine combined with cisplatin in treating patients who have locally advanced or metastatic solid tumors .
RATIONALE: Caspofungin acetate or amphotericin B liposomal may be effective in preventing or controlling fever and neutropenia caused by chemotherapy, bone marrow transplantation, or peripheral stem cell transplantation. It is not yet known whether caspofungin acetate or amphotericin B liposomal is more effective for treating these side effects. PURPOSE: Randomized phase III trial to compare the effectiveness of caspofungin acetate with that of amphotericin B liposomal in treating patients who have persistent fever and neutropenia after receiving anticancer therapy.
