Background: Genetic testing in children for hereditary cancer predisposition syndromes (CPSs) involves unique psychosocial and family-systems considerations. This retrospective study explored the perspectives and emotional reactions of parents and young adults about cancer-related genetic counseling and testing offered to children in the family.
Methods: Families were eligible if they had considered genetic testing for a child (≤18 years) within the family. Parents and young adults ≥16 years participated in semistructured interviews that we coded and identified key themes. We also quantitively assessed emotional distress, quality of life, impact of receiving genetic cancer risk information, and service-related satisfaction.
Results: From 35 interviews (26 parents, nine young adults), we identified themes spanning families' experiences from referral to genetic services to the longer term impact of receiving information about family cancer risk from testing of children. Supported by quantitative data, families generally described positive experiences of genetic services and reported benefits to genetic testing. Nevertheless, families faced unique emotional and relational challenges that changed over the family lifecycle. Those challenges differed according to whether the child was asymptomatic or had a cancer diagnosis at testing. Parents of children with cancer described genetic consultations as a secondary concern to the immediate stressors of their child's treatment.
Conclusions: We conclude that the successful integration of cancer genetics into pediatric cancer care requires specialist pediatric genetic counseling and psychosocial support services that are able to respond to families' changing needs.
