Objectives

  1. Identify individuals at high risk of cancer, especially due to personal or family medical history.
  2. Evaluate and define clinical spectrum of disease in syndromes predisposing to cancer.
  3. Quantify risks of tumors in family members.
  4. Map, clone, and determine function of tumor susceptibility genes.
  5. Identify genetic determinants and gene-environmental interactions conferring cancer risk in individuals and families.
  6. Evaluate gene-gene and gene-environmental interactions in tumor formation.
  7. Evaluate potential precursor states of disease in families at risk of cancer.

Expected Enrollment

7500

A total of 7,500 individuals will be accrued for this study. Substudies, involving subsets of the 7,500 individuals, are part of the overall study design.

Outline

One family member completes a family history questionnaire for verification of diagnosis and construction of a family pedigree. Individuals and families undergo clinical evaluation comprising at least a medical history, physical examination, and testing of blood specimens. Other biologic specimens may also be obtained from some individuals, and some individuals may undergo other diagnostic studies and examinations, depending on the type of familial neoplasm being studied.

If a family is already participating in the study and a specific mutation in a tumor predisposing gene predictive of disease has already been identified in the family, individuals may be eligible for genetic testing. Genes tested include RB1, APC, BRCA1/2, NF2, and VHL. Individuals under age 18 are only eligible to be tested for APC (familial adenomatous polyposis), NF2 (neurofibromatosis type 2), PTCH (nevoid basal cell carcinoma syndrome), RB1 (retinoblastoma), and VHL (von Hippel-Lindau disease).

Individuals may receive results of the genetic testing and genetic counseling is offered to all individuals who are tested.

A certificate of confidentiality protecting the identity of research participants in this project has been issued by the National Cancer Institute.

Families are followed every 1-2 years. In selected instances, individuals and families may return to the Clinical Center periodically for study-specific follow-up evaluations.

Note: The purpose of most clinical trials listed in this database is to test new cancer treatments, or new methods of diagnosing, screening, or preventing cancer. Because all potentially harmful side effects are not known before a trial is conducted, dose and schedule modifications may be required for participants if they develop side effects from the treatment or test. The therapy or test described in this clinical trial is intended for use by clinical oncologists in carefully structured settings, and may not prove to be more effective than standard treatment. A responsible investigator associated with this clinical trial should be consulted before using this protocol.
