NCT ID: NCT00341939 Completed - Breast Cancer Clinical Trials

Retrospective Analysis of a Drug-Metabolizing Genotype in Cancer Patients and Correlation With Pharmacokinetic and Pharmacodynamics Data

Start date: September 7, 2004
Phase:
Study type: Observational

This study is a retrospective one, exploring the hypothesis that a person's genotypic makeup may be associated with a clinical response or toxic effect to a drug. Genetic polymorphisms, that is, states of being able to assume different forms, that are in drug-metabolizing enzymes, transporters, and receptors may affect a patient's response to drug therapy. To date, there have been limited studies looking at a drug-metabolizing genotype (genetic makeup) or phenotype (result of the genotype's interaction with the environment). However, it is often wondered if the variations in a drug's action, that is, pharmacokinetic effect, come from the genotype phenotype relationship. Participants who entered previous clinical trials at the National Cancer Institute, as approved by the Central Institutional Review Board, may be eligible for this study. Studies for which pharmacokinetic analyses were or are being performed will be the source of the patient population. Genotyping experiments will be performed through genomic DNA isolated from stored frozen serum. The genotyping results will be compared with pharmacokinetic data and clinical outcomes. Clinical data will consist of what is obtained during the course of the principal pharmacokinetic study. The results of the retrospective analyses will provide no direct benefit to the participants.

NCT ID: NCT00341835 Completed - Lung Cancer Clinical Trials

Genetic Epidemiology of Lung Cancer

Start date: August 26, 2003
Phase:
Study type: Observational

This study will search for genes that greatly increase the risk of developing lung cancer in conjunction with cigarette smoking or other environmental agents, or both. Lung cancer is the second most common cancer diagnosed among men and women and the leading cause of cancer death in the United States. It has been frequently given as an example of cancer determined only by the environment, certain occupations, and dietary habits. Yet researchers have long had a hypothesis that people vary in their risk of becoming affected when exposed to these factors. Also, some evidence has shown that lung cancer in families may be due to the combined effects of inheritance of a major gene and cigarette smoking. Individuals who have a confirmed diagnosis of lung cancer or a family history of lung cancer may be eligible to enroll their families in the study. Family members will be asked to do one or more of the following: - Complete a questionnaire about personal medical history, lifestyle, and diet. - Have blood drawn from a vein in the arm. - If a family member has had a biopsy or is scheduled for one, give permission to obtain medical records and a portion of the stored tissue. - If any relatives have died of cancer, sign a release form to allow researchers to get copies of medical and pathology records, and tissue samples from surgery. If the family members agree, they may be recontacted to answer questions about their health and those of their family, during an annual telephone conversation. Follow-up questionnaires may be sent to participants, to determine if any new cancers have developed in the family. In the event of a new cancer, the classification of the family may change from the low-risk to intermediate risk-level and from the intermediate-risk to high-risk level. Follow-up will continue, to get information about tumors and death. Also, a newsletter for lung cancer families will occasionally be distributed to participants. In the future, the Internet will also provide information for families.

NCT ID: NCT00341341 Completed - Lung Cancer Clinical Trials

Impact of Lung Cancer Diagnosis on Relatives' Understanding of Genetic Risk and Receptivity to Quit Smoking

Start date: December 7, 2004
Phase: N/A
Study type: Observational

This study will explore beliefs and knowledge about genetics and smoking among smokers who have a first or second degree relative with advanced lung cancer, and whether their understanding of genetic risk influences their desire to quit smoking. Healthy adult smokers between 18 and 55 years of age who are first or second degree relatives (e.g., siblings, children, grandchildren, nieces, nephews, grandnieces or grandnephews) of a patient with advanced lung cancer who is receiving care at the Moffitt Cancer Center and Research Institute in Tampa, Fla. and the GUMC/LCCC, may be eligible for this study. Participants must be able to complete computer online surveys. Participants log on to a password-protected website to complete online educational sessions and surveys. The educational sessions include information on: 1) the role of smoking and genetics in the development of lung cancer; 2) glutathione S transferase (GSTM1), an enzyme made by the GSTM1 gene that "cleans up" toxins such as cigarette smoke and that may play a role in preventing lung cancer from developing; 3) pros and cons of being tested for GSTM1; and 5) a series of questions and answers about genetic testing. Participants are offered free genetic testing for GSTM1, and those who wish to be tested are sent materials to collect a sample from inside the cheek using a mouth rinse and return it to a laboratory at Duke University Medical Center. They later receive their results online. Participants also complete online surveys that ask about their risk perceptions, beliefs and attitudes related to lung cancer, emotional responses to their relative's diagnosis, smoking history and motivation to quit, reactions to information about smoking and genetic risk, and interest in receiving smoking cessation services. They are asked to review depictions and descriptions of smoking cessation materials offered through a quit smoking program at Duke University Medical Center and to evaluate the extent to which the various materials might be helpful. They are offered additional information among categories they can choose from. Participants are surveyed again by telephone 6 months after completing the online surveys.

NCT ID: NCT00340847 Completed - Lung Cancer Clinical Trials

Construction and Use of Lung Tumor Microarray for the Analysis of Gene Expression in Lung Cancer

Start date: August 9, 2001
Phase: N/A
Study type: Observational

The proposed research intends to construct a set of tissue microarrays containing different types of normal and lung cancer tissues for the study of genes associated with lung cancer. Thus far we have generated a lung cancer tissue arrayusing paraffin embedded archival tissues from 300 lung turmors tissues and 100 adjacent normal tissues. Four- micrometer thickness sections have been cut from the tissue array and were used to survey gene expression status in arrayed tumors using immunohistochemistry methody. We are currently performing IHC studies ot 1) determine protein expression and its correlation with gene expression patterms ovserved using cDNA arrays. 2) Analyze protein expression in the chromosome remodeling pathyway in non-small cell lung cancer. And 3) determine the association of gene expression with lung tumor stage and clinical outcome. The current protocol is needed to complete the above studies and for the production of neuroendocrine tumors.

NCT ID: NCT00340405 Active, not recruiting - Lung Cancer Clinical Trials

Development of a Biologic Specimen Bank for the Study of Early Markers of Lung Cancer Among Tin Miners in Yunnan, China

Start date: April 30, 1992
Phase:
Study type: Observational

The overall goal of this project is to identify strategies to reduce lung cancer incidence and mortality. Using a high-risk occupational cohort, our specific objectives are 1) to establish a biologic specimen bank and data bank that can be used for the validation and refinement of potential early markers of lung cancer, and 2) to establish a cohort for the study of environmental (including dietary) and genetic risk factors for lung cancer. Lung cancer is the leading cause of death from malignant neoplasms in the United States and in many countries around the world. Potential strategies to reduce the incidence and mortality of lung cancer include new methods of early detection and identification and alteration of etiologic factors. The Yunnan Tin Corporation (YTC), located in Yunnan Province in southern China, is a large, nonferrous-metals industry, formed in 1883 and nationalized after the establishment of the People's Republic in 1949. It is involved principally in the production of tin from the mines around the city of Gejiu. The tin miners at YTC have extremely high rates of lung cancer. Among those at high risk, defined as miners 40+ years old with 10+ years of underground mining and/or smelting experience, more than one percent per year develop lung cancer. These extraordinary lung cancer rates result from combined exposure to radon, arsenic, and tobacco smoking in the form of cigarettes and/or bamboo water pipe. The study population for the development of a biologic specimen bank for the study of early markers of lung cancer is all YTC miners considered to be at high risk for lung cancer based on their occupation exposure (40+ years old with 10+ years of underground or smelting experience). Currently numbering over 7,000, this high-risk group has been the target for the annual lung cancer screening program at the YTC for the past 20+ years. For each high-risk miner, sputum samples are collected annually, read for cytologic interpretation, and stored in Saccomanno's solution for future early marker research. Screening chest x-rays are also obtained. Subjects are followed annually to determine if any have developed lung cancer. Diagnostic workup of suspicious cases includes an additional sputum sample and histology specimen(s), which are used for diagnostic purposes and also retained for future research. Additional biologic specimens have also been obtained on screenees for etiologic research, including a one-time collection of whole blood, urine, and toenail clippings. Finger stick bloods and buccal smears for DNA will also be sought.

Genetic Epidemiology of Lung Cancer and Smoking

Start date: June 28, 2001
Phase:
Study type: Observational

We will conduct an interdisciplinary case-control/sib-pair study of lung cancer designed to explore the genetic determinants both of lung cancer and of smoking. The study includes biospecimen collection as well as exposure information with power to address main genetic effects and gene-environment interactions. This is an integrated proposal designed to address two major issues: the genetic determinants of lung cancer in smokers and the genetic determinants of smoking. Other important issues will be addressed in the study with a marginal additional cost to the main design. The study achieves excellent power for studying the main effects of genetic factors that are relatively common and good power for formal tests of interactive effects. Using a case-control design, with questionnaire, medical record abstraction, and blood collection, we will investigate: main effects of genes on lung cancer risk; gene-environment and gene-gene effects in lung cancer etiology; gene effects on smoking persistence; gene effects on ever-never smoking; gene-psychological interactions in smoking behaviors. In addition, we will collect viable lymphocytes from all study subjects and tumor, metaplastic and normal tissue samples from 100 surgical cases. With these data and tissues, we will be able to study: genetic instabilities in lung cancer tissue in relation to specific exposures, genotype, persistence of smoking, and clinical presentation of lung cancer; histologic characteristics of lung cancer in relation to genotype, gene expression, somatic mutations, and smoking; functional assays in viable lmphocytes in relation to genotype, gene expression. Finally, we will identify lung cancer-affected siblings of cases, and the unaffected siblings in the same sibships. This sample will permit us to: replicate associations found in the case-control sample with an alternative analytical method based on transmission statistics; address some population stratification issues.

NCT ID: NCT00334763 Terminated - Lung Cancer Clinical Trials

Radiation Therapy, Chemotherapy, and Bevacizumab in Treating Patients With Recurrent, Unresectable or Stage III or Stage IV Non-Small Cell Lung Cancer

Start date: May 2006
Phase: Phase 2
Study type: Interventional

RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells. Drugs used in chemotherapy, such as paclitaxel and carboplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as bevacizumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Bevacizumab may also stop the growth of tumor cells by blocking blood flow to the tumor. Giving radiation therapy together with chemotherapy and monoclonal antibody therapy may kill more tumor cells. PURPOSE: This phase II trial is studying how well giving radiation therapy together with chemotherapy and bevacizumab works in treating patients with recurrent, unresectable or stage III or stage IV non-small cell lung cancer.
