Genetic Epidemiology of Lung Cancer
Completed
Conditions studied: Lung Cancer
In brief
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.

- Excluded from the study are families or individuals within the family who do not meet the minimum criteria described above. Individuals who do not sign the Consent Form will be excluded, and families for whom all necessary members do not sign the Consent Form may be excluded. MAYO also excludes patients who (1) do not speak English, (2) are non-US citizens or residents and (3) are diagnosed with an uncommon tumor type that is not among the above specified types (e.g.) mixed cell or unspecified non-small cell lung cancer, carcinoids, sarcomas and lymphomas of the lung and bronchus). This is done at MAYO because the family study is piggy-backed onto a case-control study. No fetuses, prisoners or institutionalized individuals will be enrolled. While this study does not target pregnant women, because contact with many of the families will be by mail we will not be able to exclude pregnant women. Additionally, the participant's own physician or health care clinic will draw blood samples from long-distance participants and therefore can determine if there is any risk to the woman or her fetus. UMHS also excludes children as research participants in their site.
