Family Health Leaders: Lessons on Living with Li-Fraumeni Syndrome across Generations.

Li-Fraumeni Syndrome (LFS) is a hereditary disorder that confers an approximately 90% lifetime risk of cancer and requires comprehensive lifetime cancer screening. We explored healthcare roles for managing LFS-related cancer risks and treatments that were assumed by parents, adolescents, and adult children. Semi-structured interviews were conducted with 23 families.

A Pragmatic Testing-Eligibility Framework for Population Mutation Screening: The Example of .

Background: Eligibility guidelines for genetic testing may be revisited, given technological advances, plummeting costs, and proposals for population mutation screening. A key property of eligibility criteria is the tradeoff between the number of mutation carriers identified versus population members tested. We assess the fractions of mutation carriers identified, versus women undergoing mutation testing, for founder mutation screening in U.

Couples coping with screening burden and diagnostic uncertainty in Li-Fraumeni syndrome: Connection versus independence.

Purpose: Li-Fraumeni Syndrome (LFS) is an inherited tumor predisposition syndrome with lifetime cancer risks approaching 100% and evolving risk-management strategies. This study evaluated couples' coping with LFS-related burdens.

Research Approach: Constructivist grounded theory and anticipatory loss frameworks guided design and analysis.

Legacies and Relationships: Diverse Social Networks and BRCA1/2 Risk Management Decisions and Actions.

In families with hereditary breast/ovarian cancer, complex disease histories challenge established patterns of family communication and influence decision-making for clinical surveillance, genetic testing, and risk management. An interdisciplinary team examined longitudinal interview data from women with identified BRCA1/2 mutations to assess interactions within family and social networks about risk information communication and management. We used interpretive description to identify motivation, content, and derived benefit of these interactions.

Baseline Surveillance in Li-Fraumeni Syndrome Using Whole-Body Magnetic Resonance Imaging: A Meta-analysis.

Importance: Guidelines for clinical management in Li-Fraumeni syndrome, a multiple-organ cancer predisposition condition, are limited. Whole-body magnetic resonance imaging (WBMRI) may play a role in surveillance of this high-risk population.

Objective: To assess the clinical utility of WBMRI in germline TP53 mutation carriers at baseline.

Prevalence of Cancer at Baseline Screening in the National Cancer Institute Li-Fraumeni Syndrome Cohort.

Importance: Establishment of an optimal cancer surveillance program is important to reduce cancer-related morbidity and mortality in individuals with Li-Fraumeni syndrome, a rare, highly penetrant cancer predisposition syndrome.

Objective: To determine the feasibility and efficacy of a comprehensive cancer screening regimen in Li-Fraumeni syndrome, using multiple radiologic techniques, including rapid whole-body magnetic resonance imaging (MRI) and laboratory measurements.

Design, Setting, And Participants: Baseline evaluation of a prospective cancer screening study was conducted from June 1, 2012, to July 30, 2016, at the National Cancer Institute, National Institutes of Health (an academic research facility).

Risks of first and subsequent cancers among TP53 mutation carriers in the National Cancer Institute Li-Fraumeni syndrome cohort.

Background: Li-Fraumeni syndrome (LFS) is an autosomal dominant cancer predisposition syndrome characterized by a very high lifetime cancer risk and an early age at diagnosis of a wide cancer spectrum. Precise estimates for the risk of first and subsequent cancers are lacking.

Methods: The National Cancer Institute's Li-Fraumeni Syndrome Study includes families meeting the diagnostic criteria for LFS or Li-Fraumeni-like syndrome, and individuals with a germline TP53 mutation, choroid plexus carcinoma, adrenocortical carcinoma, or ≥3 cancers.

Research participant interest in primary, secondary, and incidental genomic findings.

Purpose: To define the frequency with which adult research participants consent to be offered clinically validated research genetic test results (RR) and incidental findings (IF).

Methods: Consents were obtained from 506 adults enrolled in one of three studies within the National Cancer Institute Clinical Genetics Branch's Familial Cancer Research Program. A cross-sectional analysis was performed involving the choices indicated on study consents regarding receipt of RR and IF.

Easing the Burden: Describing the Role of Social, Emotional and Spiritual Support in Research Families with Li-Fraumeni Syndrome.

This study presents findings of a mixed-method descriptive exploration of the role of friends and spirituality/religiosity in easing the burden of families with the rare inherited disorder, Li-Fraumeni Syndrome (LFS). LFS is caused by germline mutations in the TP53 gene and is associated with very high lifetime risk of developing one or more malignancies. During the first clinical visit we assessed several types of social support among a subset of study participants (N = 66) using an established interactive research tool called the Colored Eco-Genetic Relationship Map (CEGRM).

Genetic Information-Seeking Behaviors and Knowledge among Family Members and Patients with Inherited Bone Marrow Failure Syndromes.

Inherited bone marrow failure syndromes (IBMFS) including Fanconi anemia, dyskeratosis congenita, Diamond-Blackfan anemia, and Shwachman-Diamond syndrome are rare genetic disorders characterized by hematologic complications and increased risk of cancer. Patients and their families likely experience obstacles in obtaining sufficient health information given their disorders' rarity. To investigate this possibility, we examined information-seeking behaviors and levels of general and disorder-specific genetic knowledge among 315 members of 174 families with an IBMFS, and how information-seeking behaviors and socio-demographic factors may be associated with their genetic knowledge.

Familial testicular germ cell tumor: no associated syndromic pattern identified.

Background: Testicular germ cell tumor (TGCT) is the most common malignancy in young men. Familial clustering, epidemiologic evidence of increased risk with family or personal history, and the association of TGCT with genitourinary (GU) tract anomalies have suggested an underlying genetic predisposition. Linkage data have not identified a rare, highly-penetrant, single gene in familial TGCT (FTGCT) cases.

Li-Fraumeni syndrome: report of a clinical research workshop and creation of a research consortium.

Li-Fraumeni syndrome (LFS) is a rare dominantly inherited cancer predisposition syndrome that was first described in 1969. In most families, it is caused by germline mutations in the TP53 gene and is characterized by early onset of multiple specific cancers and very high lifetime cumulative cancer risk. Despite significant progress in understanding the molecular biology of TP53, the optimal clinical management of this syndrome is poorly defined.

Close ties: an exploratory Colored Eco-Genetic Relationship Map (CEGRM) study of social connections of men in Familial Testicular Cancer (FTC) families.

Background: Testicular cancer, while rare compared with other adult solid tumors, is the most common cancer in young men in northern Europe and North America. Risk factors include white race, positive family history, contralateral testicular cancer, cryptorchidism, infertility and testicular microlithiasis. As the genetic causes of familial clusters (Familial Testicular Cancer or FTC) are being sought, it is also important to understand the psycho-social experiences of members of FTC families.

Essential elements of genetic cancer risk assessment, counseling, and testing: updated recommendations of the National Society of Genetic Counselors.

Updated from their original publication in 2004, these cancer genetic counseling recommendations describe the medical, psychosocial, and ethical ramifications of counseling at-risk individuals through genetic cancer risk assessment with or without genetic testing. They were developed by members of the Practice Issues Subcommittee of the National Society of Genetic Counselors Familial Cancer Risk Counseling Special Interest Group. The information contained in this document is derived from extensive review of the current literature on cancer genetic risk assessment and counseling as well as the personal expertise of genetic counselors specializing in cancer genetics.

Unpacking the blockers: understanding perceptions and social constraints of health communication in hereditary breast ovarian cancer (HBOC) susceptibility families.

Family communication is essential for accurate cancer risk assessment and counseling; family blockers play a role in this communication process. This qualitative analysis of social exchanges is an extension of earlier work characterizing those who are perceived by study participants as health information gatherers, disseminators, and blockers within families with Hereditary Breast and Ovarian Cancer (HBOC) susceptibility. Eighty-nine women, ages 23-56 years, enrolled in a Breast Imaging Study (BIS) and participated in a sub-study utilizing a social assessment tool known as the Colored Ecological Genetic Relational Map (CEGRM).

Malignancies and survival patterns in the National Cancer Institute inherited bone marrow failure syndromes cohort study.

Fanconi anaemia (FA), dyskeratosis congenita (DC), Diamond-Blackfan anaemia (DBA), and Shwachman-Diamond syndrome (SDS) comprise major inherited bone marrow failure syndromes (IBMFS). Adverse events include severe bone marrow failure (BMF), myelodysplastic syndrome (MDS), acute myeloid leukaemia (AML), and solid tumours (ST). The natural history of FA is well characterised; hazard rates in the other syndromes have not yet been quantified.

Familial testicular germ cell tumors in adults: 2010 summary of genetic risk factors and clinical phenotype.

Familial aggregations of testicular germ cell tumor (FTGCT) have been well described, suggesting the existence of a hereditary TGCT subset. Approximately 1.4% of newly diagnosed TGCT patients report a positive family history of TGCT.

Characteristics of health information gatherers, disseminators, and blockers within families at risk of hereditary cancer: implications for family health communication interventions.

Objectives: Given the importance of the dissemination of accurate family history to assess disease risk, we characterized the gatherers, disseminators, and blockers of health information within families at high genetic risk of cancer.

Methods: A total of 5466 personal network members of 183 female participants of the Breast Imaging Study from 124 families with known mutations in the BRCA1/2 genes (associated with high risk of breast, ovarian, and other types of cancer) were identified by using the Colored Eco-Genetic Relationship Map (CEGRM). Hierarchical nonlinear models were fitted to characterize information gatherers, disseminators, and blockers.

Tolerability of breast ductal lavage in women from families at high genetic risk of breast cancer.

Background: Ductal lavage (DL) has been proposed as a minimally-invasive, well-tolerated tool for obtaining breast epithelial cells for cytological evaluation of breast cancer risk. We report DL tolerability in BRCA1/2 mutation-positive and -negative women from an IRB-approved research study.

Methods: 165 BRCA1/2 mutation-positive, 26 mutation-negative and 3 mutation unknown women underwent mammography, breast MRI and DL.

Factors associated with testicular self-examination among unaffected men from multiple-case testicular cancer families.

Background: The lifetime testicular cancer (TC) risk in the general population is relatively low (~1 in 250), but men with a family history of TC are at 4 to 9 times greater risk than those without. Some health and professional organizations recommend consideration of testicular self-examination (TSE) for certain high-risk groups (e.g.

All in the family: disclosure of "unwanted" information to an adolescent to benefit a relative.

Ethical assessments of clinical decisions are typically based on the preferences and interests of the individual patient. However, some clinical interventions, such as genetic testing or organ donation, may involve multiple family members. In these cases, one family member may have the potential to benefit, while another family member is exposed to potential physical or psychological risk.

BRCA mutation-negative women from hereditary breast and ovarian cancer families: a qualitative study of the BRCA-negative experience.

Background: When women from families with a known BRCA1 or BRCA2 mutation test negative for the family mutation, it is assumed that they will transition their personal cancer risk perception from high to average risk. However, there are scant data regarding the experience of mutation-negative women after genetic testing disclosure, particularly related to the shift of risk perception from assumed mutation-positive to actual mutation-negative. This study was designed to explore cancer risk perception and the experience of being a mutation-negative woman within a known BRCA1/2 mutation-positive family.

Sisters in hereditary breast and ovarian cancer families: communal coping, social integration, and psychological well-being.

Objective: We investigated the association between psychological distress and indices of social integration and communal coping among sisters from hereditary breast and ovarian cancer (HBOC) families.

Sample And Methods: Sixty-five sisters from 31 HBOC families completed the Brief Symptom Inventory-18 and the Colored Eco-Genetic Relationship Map, which identified members of participants' social support networks. Hierarchical linear models were used for all analyses to account for the clustering of sisters within families.

Testicular cancer and genetics knowledge among familial testicular cancer family members.

Purpose: It was our aim to determine baseline levels of testicular cancer and genetics knowledge among members of families with Familial Testicular Cancer (FTC).

Methods: This is a sub-study of an ongoing National Cancer Institute (NCI) multidisciplinary, etiologically-focused, cross-sectional study of FTC. We evaluated 258 male and female participants including testicular cancer (TC) survivors, blood relatives and spouses to assess factors associated with a Genetic Knowledge Scale (GKS) and Testicular Cancer Knowledge Scale (TCKS).
