Filter by:Background: Some people may be prone to develop cancer for many reasons. Factors that affect their risk include the genes they inherit and the environment they live and work in. Researchers want to learn more about the natural history of cancer. Objective: To understand how genes and environmental factors can cause tumors and related conditions. Eligibility: People of any age who: Have tumors of an unusual type, pattern, or number Have a family member with a history of cancer Have been exposed to other factors that may increase their risk of cancer Design: This study does not involve treatment. Participants will answer questions about their personal and family medical history. They will give permission for researchers to see their medical records. Participants may be invited to the NIH Clinical Center for a physical exam. They may give samples including saliva, cheek cells, blood, urine, skin, and/or hair. Participants with cancer may give bone marrow. A needle will be used to remove a small sample of bone marrow from their hip bone. Participants may have a biopsy of their tumor. Participants may have other exams: Dental Ear, nose, and throat Eye Hearing Heart function and structure Participants with cancer may undergo more exams: A test of how much energy their body uses when resting A sleep study with a test that measures brain electrical activity. They will have sensors attached to their body while they sleep overnight in a lab. Imaging scans, such as CT, MRI, a test to measure how dense their bones are (DEXA), and ultrasound. Participants will have their genes tested. A counsellor will help them understand the results. Participants will be followed until at least 2035....
This is a clinical, epidemiologic, genetic, and laboratory study of individuals and families at high risk of cancer and selected tumors to investigate the genetic susceptibility and environmental exposures which may alter cancer risk. Families with multiple members who have an unusual pattern or number of cancers or tumors are evaluated clinically. This evaluation is specific for the type of cancer or tumor predominant in the family in order to determine the affection status of each individual for genetic epidemiologic studies. Genetic and environmental risk factor information specific for the tumor type is obtained. Individuals with, or at high risk of, cancer because of their personal, familial, or environmental histories are identified by healthcare worker referral or by personal inquiry. Relevant etiologic risk factor information is documented through review of pathology specimens and medical, vital, and genealogical records. Selected individuals and family members are asked to complete questionnaires and to undergo clinical evaluations specific for the tumor of interest. They are also asked to donate biologic specimens to be used in the search for cancer etiology and mechanisms of carcinogenesis. No therapy beyond counseling and education for cancer prevention, risk reduction, and early detection will be given. Genetic testing for tumor susceptibility gene(s) mutations and risk notification will be offered to study participants for whom a specific mutation predictive of disease has been identified in his/her family. This testing will only be offered when reasonable individual cancer risk estimates can be delivered, and only to those participants who choose to know their individual genetic status after appropriate education and counseling. The testing will be conducted exclusively in Clinical Laboratory Improvement Amendments (CLIA)-licensed laboratories. Genetic testing and risk notification are entirely optional and do not affect participation in other aspects of the protocol. A separate consent procedure and consent form will be used for genetic testing and risk notification related to these specific genes. Once enrolled, study participants are monitored prospectively for the development of outcomes of interest, typically by means of periodic mail or telephone contact. In selected instances, subjects may return to the Clinical Center periodically for study-specific follow-up examinations. Although we do not offer specific anti-cancer therapy as part of this protocol, we provide assistance to insure that study participants who require treatment for tumor-related problems that develop during the course of the study are referred to appropriate healthcare providers. We remain available to study participants and their healthcare providers for advice and consultation related to the management of familial cancer/tumor predisposition. ...
