Study of Clinical and Genetic Aspects of Li-Fraumeni Syndrome and Related Conditions Observing Cancer Risks and Effects in Affected Families

What this Trial Is About

Researchers are studying Li-Fraumeni syndrome LFS, a genetic condition that greatly increases the risk of developing various cancers, including bone, connective tissue, breast, brain cancers, certain leukemias, and others. The study aims to better understand the types of cancers in people with LFS, investigate the role of the TP53 gene and other possible genetic causes, and explore factors that might raise or lower cancer risk. It also looks into how an LFS diagnosis impacts families and the potential influence of environmental and genetic factors on cancer risk. Participants will complete medical and family history questionnaires, provide blood or cheek cell samples for DNA analysis and storage, and may opt for cancer screening involving blood tests, imaging, and other exams. They will also fill out questionnaires about cancer-related worries, stress, coping, diet, and physical activity, with additional psychological tests as needed. The study involves long-term monitoring with regular follow-up visits at the National Institutes of Health for those indicated. Throughout the study, researchers will review medical records, clinical and research evaluations, laboratory tests, and cancer surveillance data. Participants health changes and cancer status will be recorded over several years. The study also includes education and risk management guidance, and it aims to build a biospecimen repository for future research. The main measurement is the occurrence of cancer in individuals and families with LFS or related syndromes.
