Pediatric Predispositional Genetic Risk Communication: Potential Utility for Prevention and Control of Melanoma Risk as an Exemplar

Pediatric DTC Genetic Testing for Adult-Onset Inherited Cancer Risk: The Perspectives of High-Risk Parents

INTRODUCTION

Despite guidelines discouraging pediatric genetic testing for adult-onset hereditary cancer risk, direct-to-consumer (DTC) companies make them available to children's parents. This study examined the perspectives of high-risk parents toward such testing.

METHODS

Interviews were conducted with N = 30 parents (children ages 10-21) carrying pathogenic variants in cancer-causing genes available for detection through DTC tests. Interviews were analyzed inductively using a standardized methodology to identify prominent themes.

RESULTS

Three major themes were identified: (1) high-risk parents' motivations for pediatric genetic testing, (2) risks and benefits of pediatric genetic testing, and (3) parental involvement of children in decision-making about testing. Although only n = 5 parents (17% of the sample) reported that their children were genetically tested (n = 3 through a DTC company, n = 2 through a clinician), 73% endorsed pediatric genetic testing for general health reasons. Many parents (53%) expressed a preference for clinical testing over DTC testing. While parents recognized the limits of DTC testing, some (40%) expressed that it should remain available to high-risk parents for the purpose of identifying cancer risks in their children. Children's maturity (70%), interest in testing (77%), and anticipated responses to testing (43%) were cited as important decisional considerations.

CONCLUSION

Few high-risk parents utilized DTC testing for their children. Parents generally preferred the prospect of clinical testing, but some believed DTC testing should be an option available to families. Clinicians should discuss the risks and benefits of pediatric genetic testing, including DTC, with high-risk parents. This may facilitate more informed decision-making that minimizes potential harms.

Knowledge Is Power: Benefits, Risks, Hopes, and Decision-Making Reported by Parents Consenting to Next-Generation Sequencing for Children and Adolescents with Cancer

OBJECTIVES

To qualitatively describe parent perspectives of next-generation genomic sequencing (NGS) for their children with cancer, including perceived benefits, risks, hopes/expectations, and decision-making process when consenting or not consenting to NGS and prior to result disclosure.

DATA SOURCES

Qualitative interviews were used.

CONCLUSION

Altruism is an important factor in parents consenting to NGS testing, as well as making sense of their child's cancer and legacy building. Parents described realistic hopes and expectations associated with NGS participation. Although parents endorsed the likelihood of no medical benefit, those consenting to NGS felt there was no reason not to participate. Parents declining participation expressed avoidance of worry and parent guilt if a germline variant were to be disclosed.

IMPLICATIONS FOR NURSING PRACTICE

As NGS evolves into a component of the routine diagnostic workup for pediatric cancer patients, genetic nurses play a role in conducting informed consent conversations and ensuring that patients and families have realistic hopes and expectations associated with NGS.

Pharmacogenomic Testing In Pediatrics: Navigating The Ethical, Social, And Legal Challenges

For the past several years, the implementation of pharmacogenetic (PGx) testing has become widespread in several centers and clinical practice settings. PGx testing may be ordered at the point-of-care when treatment is needed or in advance of treatment for future use. The potential benefits of PGx testing are not limited to adult patients, as children are increasingly using medications more often and at earlier ages. This review provides some background on the use of PGx testing in children as well as mothers (prenatally and post-natally) and discusses the challenges, benefits, and the ethical, legal, and social implications of providing PGx testing to children.

Parent and child perspectives on perceived barriers to child sun protection and their association with sun protection strategies among children of melanoma survivors

BACKGROUND/OBJECTIVES

Children with an elevated familial risk for melanoma inconsistently implement sun protection behaviors that could mitigate their melanoma risk. Little is known about perceived barriers to child sun protection among this at-risk group and their parents, and the extent to which perceived barriers are associated with child sun protection. The goal of this study was to examine, among children with a family history of melanoma, the frequency with which children and their parents reported barriers to child sun protection and the extent to which barriers were associated with reported use of sun protection among children.

METHODS

Children with a family history of melanoma and their parents completed questionnaires assessing perceived barriers and reported child use of sun protection.

RESULTS

Common barriers to child sun protection included being bothered by implementing the behavior or forgetting. A greater number of perceived barriers were associated with less frequent child use of sunscreen, long-sleeved shirts, long pants, and shade.

CONCLUSIONS

Children at elevated risk for melanoma due to a family history of the disease and their parents perceive multiple barriers to sun protection that are associated with children's use of these melanoma preventive behaviors. Sun protection interventions for this at-risk population could provide families with specific strategies to address common barriers to implementing child sun protection.

Parent-child communication surrounding genetic testing for Li-Fraumeni syndrome: Living under the cloud of cancer

BACKGROUND

Advances in the application of genetic technologies reveal a growing number of heritable disorders associated with an increased risk to develop cancer during childhood. As genetic testing is increasingly employed in the clinical setting, it is essential to understand whether parents communicate with their children about test results and to elucidate the factors that influence the content and outcomes of these conversations.

METHODS

Semistructured interviews were conducted with 14 parents whose children tested positive for Li-Fraumeni syndrome (LFS). Semantic content analysis was performed on transcribed interviews, focusing on questions related to parent-child conversations about the genetic testing process and disclosure of positive test results.

RESULTS

All parents emphasized the importance of involving children in conversations about LFS. The majority (93%) identified as being part of "cancer families" in which prior experiences with cancer created opportunities for communication. While all had spoken with their children about cancer, only seven (50%) specifically disclosed to their children that they had tested positive for LFS. The most common reason cited for nondisclosure at the time of this study was the young age of the children.

CONCLUSION

Parents of children with LFS desire open conversations about genetic testing and cancer risk. These conversations are challenging yet essential to enable child understanding of genetic risk status and enhance compliance with health-promoting and cancer surveillance measures. Development of age-appropriate educational materials and novel clinical models to facilitate parent-child conversations about genetic test results and risk status for cancer are needed.

A novel educational intervention targeting melanoma risk and prevention knowledge among children with a familial risk for melanoma

OBJECTIVE

To examine the acceptability of and preliminary effects associated with a novel educational intervention for children at elevated risk for melanoma. The intervention incorporated information on mechanisms through which melanoma preventive behaviors mitigate risk for melanoma and was delivered to parents and children concurrently.

METHODS

Twenty-two parents (with a personal history of melanoma or spouse with a history of melanoma) and 33 children (mean age 11.8 years) were asked to complete questionnaires immediately prior to and after an educational session and at a one-month follow-up.

RESULTS

Both parents and children endorsed that the educational materials were acceptable. Knowledge about melanoma risk and preventive and screening behaviors increased significantly. Children's perceived risk for melanoma increased significantly, while parents' perceptions of children's risk started at a higher level and remained constant. There were significant increases in reported engagement in sun protective behaviors.

CONCLUSION

The educational intervention shows promise in terms of its acceptability and effects on participant knowledge, perceived risk, and engagement in melanoma preventive behaviors.

PRACTICE IMPLICATION

Children at elevated risk for melanoma and their parents may benefit from receiving educational information on their disease risk and strategies for prevention and screening.
