Summary

RATIONALE: Gathering information about genetic and environmental factors from patients with lung cancer and their partners and first-degree relatives may help doctors learn more about the disease.

PURPOSE: This clinical trial is looking at the patterns, causes, and control of disease in patients with lung cancer in the North Trent (England) region.

Description

OBJECTIVES:

Primary

- To establish a resource bank of high quality genomic and plasma DNA and tumor and serum samples linked to clinical data obtained from detailed family history and lifestyle questionnaires from patients with lung cancer and from their partners and first-degree relatives for genetic epidemiology studies of lung cancer.

Secondary

- To study single nucleotide polymorphisms for candidate lung cancer susceptibility genes in genomic DNA samples from patients with lung cancer and from their partners and first-degree relatives.

- To study genetic changes of lung cancer in plasma DNA samples from patients with lung cancer and from their partners and first-degree relatives.

OUTLINE: This is a multicenter study.

Patients and their partners complete a detailed, interview-based questionnaire to assess their environmental risk factors for cancer. Information on past medical, social, occupational, and smoking history as well as family history, including any malignancies diagnosed and subsequent causes of death, is collected. First-degree relatives of patients complete an interview-based questionnaire about smoking, occupational, and cancer history. Relatives of patients' partners complete a telephone-administered questionnaire only.

Medical records of patients are reviewed to obtain information on pathological diagnosis and laboratory number, date of diagnosis, stage of disease, performance status, co-morbidities, and treatment plan. Medical records of partners may also be reviewed to obtain information on the incidence of smoking-related malignancies (i.e., cancer of the lung, larynx, esophagus, stomach, bladder, or head and neck).

Patients and their partners and first-degree relatives undergo blood sample collection for laboratory studies. Previously collected tumor samples are obtained from patients. Plasma DNA, lymphocyte DNA, and tumor DNA are analyzed by polymerase chain reaction (PCR) to identify loss of heterozygosity (LOH) between genomic (lymphocyte) DNA and the tumor and plasma DNA. Specific tumor-associated mutations are also analyzed by real-time PCR. Single nucleotide polymorphism studies, including common gene polymorphisms (metabolic genes, DNA repair genes, and tumor suppressor genes), in lung cancer families are also conducted.

A statistical model will be developed for future analysis and will include correlations in genetic alterations in DNA isolated from tumor and plasma, familial aggregation studies, and genetic analysis studies.

PROJECTED ACCRUAL: A total of 2,000 participants (500 patients and 1,500 partners and first-degree relatives [controls]) will be accrued for this study.

Medical and Biotech [MESH] Definitions

A method of chemical analysis based on the detection of characteristic radionuclides following a nuclear bombardment. It is also known as radioactivity analysis. (McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed)

Meta-analysis of randomized trials in which estimates of comparative treatment effects are visualized and interpreted from a network of interventions that may or may not have been evaluated directly against each other. Common considerations in network meta-analysis include conceptual and statistical heterogeneity and incoherence.

Analysis based on the mathematical function first formulated by Jean-Baptiste-Joseph Fourier in 1807. The function, known as the Fourier transform, describes the sinusoidal pattern of any fluctuating pattern in the physical world in terms of its amplitude and its phase. It has broad applications in biomedicine, e.g., analysis of the x-ray crystallography data pivotal in identifying the double helical nature of DNA and in analysis of other molecules, including viruses, and the modified back-projection algorithm universally used in computerized tomography imaging, etc. (From Segen, The Dictionary of Modern Medicine, 1992)

Methods for performing three-dimensional measurement and motion analysis using stereoscopic radiographs.

The simultaneous analysis, on a microchip, of multiple samples or targets arranged in an array format.
