Brief Summary | Li-Fraumeni Syndrome (LFS) and Li-Fraumeni-like (LFL) Syndrome are cancer predisposition syndromes due to germline aberrations in the TP53 gene. Patients with classical LFS have a lifetime malignancy risk between 80-90%, with 21% of those cancers occurring by the age of 15 years. There are established guidelines for screening patients with LFS that have led to earlier detection and treatment of cancer in this population. There are a number of important issues facing patients identified to have germline TP53 variations. First, with the advent of massively parallel sequencing, increasing numbers of patients are now being identified with a wide range of clinical phenotypes associated with germline TP53 mutations, and the natural history of these patients is less well understood. Second, surveillance for malignancy in LFS and other TP53-associated syndromes involves frequent laboratory and radiologic studies that are imperfect measures of disease onset; therefore, more specific, less invasive biomarker-driven screening methods are needed. Finally, studies to date have not yet identified whether tumors which form in LFS or other germline TP53-associated tumors have unique aberrations or signatures that could be exploited in precision medicine treatment of these patients. In order to study these important issues in LFS, this protocol will establish a TP53 Clinical Database and Biobank. The Investigator plans to use this biobank to study genotype-phenotype correlations in patients with LFS and other germline TP53-associated syndromes, mechanisms of tumor formation, and novel methods of cancer screening in this high risk population. | ||||||||
Detailed Description | Context: Li-Fraumeni Syndrome (LFS) and Li-Fraumeni-like (LFL) Syndrome are cancer predisposition syndromes due to germline aberrations in the TP53 gene. Patients with classical LFS have a lifetime malignancy risk between 80-90%. There are guidelines for screening patients with LFS that have led to earlier detection and treatment of cancer in this population. There are a number of important issues facing patients identified to have germline TP53 variations, including study of genotype-phenotype correlations, enhanced cancer screening modalities, and novel treatment strategies for cancers that develop. Objectives: In order to study important clinical issues in LFS, the primary objective of this biobank is to gather and store ongoing clinical data and biospecimens from patients with LFS and other potential germline TP53-associated syndromes. The investigators plan to use this biobank to study genotype-phenotype correlations in patients with inherited TP53 mutations, mechanisms of tumor formation, and methods of cancer screening. Study Design: This study is a retrospective/prospective biobank containing clinical data and data and biospecimen. Patients for inclusion will be identified by query of our clinical electronic medical record from the Children's Hospital of Philadelphia (CHOP) and Penn Medicine (PENN) for patients followed in our respective clinics. In addition, patients will be recruited by ongoing prospective collection in clinic. Data collection, data entry and biobank maintenance, will be conducted by the investigators listed on this protocol at CHOP and at PENN through the Master Reliance Agreement. Future investigators and collaborators at other institutions will have access to samples and limited data by executing a written Data User Agreement and/or Materials Transfer Agreement with the biobank. Setting/Participants: The biobank will be conducted at CHOP and PENN. Any infant, child, or adult with a germline TP53 mutation will be invited to participate. In addition, individuals with a diagnosis of LFS or LFL, who have been seen by a physician at Penn/CHOP or referred from outside physicians will be contacted for participation. To provide control group samples, unaffected family members and/or household members will also be recruited. Prospective enrollment into the biobank is planned to be an ongoing effort, without a fixed end date or target subject number. At minimum, however, the estimated number of recruitment is approximately 300 affected individuals and their family/household members along with their data and specimens. Data/Specimen Collection Procedures and Frequency: The only required study procedure is the review of medical records. Optional study procedures include collection of germline DNA (via blood, saliva, urine, or hair), plasma collection, stool collection, and skin biopsies. Clinical data will be updated every 6 months. Subjects can opt-out of this follow-up process. |

Study Design | Observational Model: Cohort Time Perspective: Prospective |
||||||||
Target Follow-Up Duration | 5 Years | ||||||||
Biospecimen | Retention: Samples With DNA Description: For affected patients (group 1), collection of biospecimens will occur either once (i.e., blood, buccal swabs, urine, skin fibroblasts), or every six months (i.e., plasma from blood, stool samples, and other specimens that are obtained and leftover as part of clinical care) . Unaffected family members (group 2) and household members (group 3) will only have samples requested once as per Schedule of Study Procedures (Group 3 subjects will not be asked for a germline specimen). None of these procedures are required for the subjects to participate in the study. Children <18 years will complete procedures at CHOP, and adult participants will complete study procedures at PENN (adolescents and young adults seen at CHOP clinically may have their samples collected at CHOP even if over 18 years).
