The Influence of Adolescence on Parents' Perspectives of Testing and Discussing Inherited Cancer Predisposition

Psychosocial interventions and needs among individuals and families with Li-Fraumeni syndrome: A scoping review

Li-Fraumeni syndrome (LFS), a rare cancer predisposition syndrome caused by germline mutations in the TP53 gene, is associated with significant lifetime risk of developing cancer and warrants extensive and long-term surveillance. There are psychosocial impacts on individuals and families living with this condition, from the initial diagnosis throughout multiple stages across the lifespan, but these impacts have not been systematically reviewed and organized. The objective of this scoping review was to synthesize and characterize the literature on psychosocial screening and outcomes, educational needs, support services, and available interventions for patients and families with LFS. A systematic search of six databases was most recently conducted in August 2020: (PubMed/MEDLINE (NLM), EMBASE (Elsevier), Cochrane Library (Wiley), CINAHL (EBSCO), PsycINFO (OVID), and Web of Science (Clarivate Analytics). A total of 15 757 titles were screened, and 24 articles included. Several important themes were identified across studies: factors associated with TP53 genetic testing, LFS surveillance, psychological outcomes, and communication. Findings related to these themes were organized into age-specific categories (age agnostic/across the lifespan, childhood, adolescence and young adulthood, and adulthood).

Parent-Child Communication and Reproductive Considerations in Families with Genetic Cancer Predisposition Syndromes: A Systematic Review

Background: Uptake of genetic testing for heritable conditions is increasingly common. In families with known autosomal dominant genetic cancer predisposition syndromes (CPS), testing youth may reduce uncertainty and provide guidance for future lifestyle, medical, and family building considerations. The goals of this systematic review were to examine: (1) how parents and their children, adolescents, and young adults (CAYAs) communicate and make decisions regarding testing for CPS and (2) how they communicate and make decisions about reproductive health/family building in the context of risk for CPS. Methods: Searches of MEDLINE/Pubmed, CINAHL, Web of Science, and PsycINFO yielded 4161 articles since January 1, 2000, which contained terms related to youth, pediatrics, decision-making, genetic cancer predispositions, communication, and family building. Results: Articles retained (N = 15) included five qualitative, six quantitative, and four mixed-method designs. Parents generally agreed testing results should be disclosed to CAYAs at risk or affected by genetic conditions in a developmentally appropriate manner. Older child age and child desire for information were associated with disclosure. Greater knowledge about risk prompted adolescents and young adults to consider the potential impact on future relationships and family building. Conclusions: Most parents believed it was their responsibility to inform their CAYAs about genetic testing results, particularly to optimize engagement in recommended preventative screening/lifestyle behaviors. Disclosing test results may be challenging due to concerns such as young age, developmental appropriateness, and emotional burden. Additional research is needed on how CPS risk affects CAYAs' decisions about reproductive health and family building over time.

Families' and health care professionals' attitudes towards Li-Fraumeni syndrome testing in children: A systematic review

Li-Fraumeni syndrome (LFS) is a highly penetrant cancer predisposition syndrome caused by germline TP53 mutations. Genetic testing is not routinely offered in asymptomatic children at risk of the condition as the benefits are debatable and the attitudes of families and health care professionals (HCPs) may vary. This review assessed the attitudes of families and HCPs towards offering genetic testing to children for LFS, with a focus on perceived advantages and disadvantages and involvement of children in the decision-making process. We searched three key databases (Medline, PsycINFO and EMBASE) to identify quantitative and qualitative studies. We screened 729 articles identifying eight studies for detailed review. Most parents perceived TP53 genetic testing to be beneficial in childhood, despite previous lack of surveillance guidelines. Parents raised some concerns, including decreased insurability and diminishing the child's autonomy. Most children tested reported no negative emotional concerns after testing, even if tested positive. Despite generally positive interest clinicians remain hesitant. Most families saw the value in involving children in decision-making. Families' acceptance of TP53 testing in childhood was high. This review highlights the need for research on the long-term psychosocial impacts of testing and the attitudes of families to be reflected in professional guidelines.
