Filter by:This research study is evaluating the safety and tolerability of the drug lenalidomide in combination with and following mismatched related donor microtransplantation in high risk AML patients in first remission. This study also aims to define the maximum tolerated dose (MTD) of lenalidomide given in this setting. Microtransplantation seeks to give the participant donor cells in hopes that those cells can attack the underlying cancer. However, since the donor cells do not replace all of the host cells, it can hopefully avoid many of the serious risks involved with standard transplant, including graft-vs.-host disease (GVHD) - a complication where the donor cells attack the participant's normal body. Recent studies have suggested that lenalidomide can help aid donor cells to attack cancer when given after a stem cell transplant. This trial is trying to see if lenalidomide can help encourage the attack of leukemia cells by donor cells given as part of microtransplantation. The FDA (the U.S. Food and Drug Administration) has approved lenalidomide but it has been approved for other uses such as in the treatment of other cancers including multiple myeloma and non-Hodgkin lymphoma. Although lenalidomide has been studied in patients with AML, it has not been approved by the FDA for standard use in AML. Lenalidomide is a compound made by the Celgene Corporation. It has properties which could demonstrate antitumor effects. The exact antitumor mechanism of action of lenalidomide is unknown.
This study will examine the risks of workplace exposure to benzene, a substance known to lead to cancer of the blood and possibly of the lungs. It is used widely in industries and is a contaminant in the environment. Researchers from the National Cancer Institute and the China Center for Disease Control (formerly Chinese Academy of Preventive Medicine) had done previous studies of workers in manufacturing industries in China of people who worked at least 1 day from 1972 to 1987 in 12 cities in that country. Data were collected of approximately 75,000 workers exposed to benzene and 35,000 who were not, with the purpose of investigating the relationship between benzene exposure and cancer risk. For workers exposed to benzene, there was a significant risk of cancer affecting the blood cells and a 1.8-fold excess of lung cancer among them. This study will expand those findings and also identify the effects of benzene amounts and whether there is a genetic tendency for benzene poisoning. About 3,860 benzene-exposed workers from the 12 cities will be interviewed. Next-of-kin of deceased workers, and a subcohort (additional grouping) of participants will serve as a control group in the research. Patients who have worked at places where there was exposure to benzene will have a brief physical exam and samples of cells from a mouth rinse and samples from blood will be collected to study the genetic influence on developing blood diseases from workplace exposures. All participants or next-of-kin, for deceased, will be given a questionnaire about their work history, use of cigarettes and hair dyes, medications they take, and family history of cancer. Interviews of about 40 minutes long will be conducted at participants homes or workplaces, at a time convenient to them, and the interviews will be audiotaped.
