Summary

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.
