What is Li-Fraumeni Syndrome (LFS)?
Genetics can’t be changed, but the way we approach our healthcare can be.
Learn about a genetic condition that greatly increases the risk of cancer.
Awareness of LFS is Important
LFS is a rare genetic disorder that greatly increases the risk of developing many types of cancer. Cancers related to this condition may occur at any age, but a characteristic feature of LFS is a high risk for cancer occurring in childhood. Approximately 40% of individuals with LFS will develop cancer in childhood. LFS affects both men and women and this condition has been identified in families all over the world.
The Most Common Types of Cancer Associated with LFS Include:
• Breast cancer
• Adrenocortical cancer
• Soft tissue sarcomas
• Brain tumors
• Colon cancer
• Stomach cancer
• Lung Bronchoalveolar cancer
The types of cancers and ages of development do vary between LFS families. Review of the family history and information about the specific genetic alteration that has caused LFS may help doctors and genetic counselors provide more specific cancer risk information.
Understanding What Causes LFS
LFS is caused by a mutation in the TP 53 tumor suppressor gene. When working properly, this gene controls cell growth, preventing cancers from forming. Individuals with LFS lack a properly functioning p53 gene.
Most people with LFS inherited a mutation from a parent, but LFS can also result from a new mutation without having affected parents or a family history of cancer. A child of a parent with LFS has a 50% chance of inheriting the disorder. For this reason, LFS patients should discuss the significant reproductive implications with their doctors.
Know the Facts on Diagnosis
Determining if a person or family has LFS begins with taking a family history. Individuals with an aderenocortical carcinoma or choroid plexus carcinoma, as well as those meeting the criteria listed within, should be evaluated for LFS.
A referral will often be made to a genetic counselor, a health care provider who specializes in diagnosing hereditary conditions, to provide families with an opportunity to discuss the implications of genetic testing. Genetic testing involves analyzing a sample of blood or saliva for alterations in the TP53 gene. Ideally, the process of genetic testing should begin with a family member who has had cancer. If an alteration causing LFS is identified, then other relatives should be tested to determine who else may be at risk.
If You Meet Any of the Following Criteria, Talk to Your Physician About LFS Screening:
• You have been diagnosed with a cancer within the LFS spectrum of cancers (soft tissue sarcoma, osteosarcoma, brain tumor, pre-menopausal breast cancer, adrenocortical cancer, leukemia or bronchoalveolar lung cancer) before age 46 AND have at least one first or second degree relative with an LFS related cancer before 56 years of age
• You have been diagnosed with multiple cancers, 2 of which belong to LFS spectrum of cancers, with first cancer before age of 46
• You are a woman diagnosed with breast cancer before age 35 and have tested negative for a BRCA1 or BRCA2 mutation
• You have a history of adrenocortical cancer or choroid plexus carcinoma
Why Diagnosis Can Make a Difference
While the diagnosis of LFS can seem overwhelming, it is critical that patients be aware of the disorder so they may adequately manage their healthcare. Because patients with LFS often develop cancers earlier, regular check-ups and cancer screenings are extremely important – the sooner a cancer is diagnosed and treated, the better the chances of a successful treatment. Coordination with individual medical providers is also crucial to ensure that the LFS diagnosis is being considered in the treatment of conditions, particularly in regard to the use of radiation therapy in cancer treatment.
Educating and Empowering Families with LFS
Support for families and individuals with LFS may be found through the LFS Association (LFSA). LFSA provides a wide range of information, advocacy, and support services for those living with LFS. Additionally, they support the Life Consortium of researchers, medical providers, and caregivers. This unique partnership between the patient organization (LFSA) and medical consortium (LiFE) uniquely empowers the LFS community and facilitates our support for LFS families.
About the LiFE Consortium
The Li-Fraumeni Exploration (LiFE) Research Consortium is a group of dedicated physicians and scientists from around the world whose goal is to improve the lives of those with LFS. They have a tremendous interest in LFS and with their wide ranging expertise are advancing our knowledge of LFS through collaborative research and clinical trials.
