Experiences of pediatric cancer patients (age 12-18 years) with extensive germline sequencing for cancer predisposition: a qualitative study.

ABSTRACT

This study explored the experiences and needs of adolescents, ranging from 12 to 18 years old, who have recently been diagnosed with cancer and participated in a nationwide germline genetic sequencing study within the context of pediatric oncology. The 21 adolescents in this qualitative interview study viewed genetic sequencing as an integral part of their cancer journey. They often characterized germline sequencing as "good-to-know" without specifying immediate utility. While the adolescents comprehended the significance of germline genetic sequencing, they were less focused on its potential long-term implications. Adolescents expressed a strong desire to be actively engaged in decisions related to genetics. They advocated for a participatory role in genetic decision-making from a young age onwards. They recommended that re-consent should be sought before re-analysis of their genetic data is performed and believe that patients should have the opportunity to provide (re-)consent once they reach adulthood. Moreover, the adolescents emphasized the importance of developing counseling materials that are not only concise but also visually attractive. In conclusion, this study underscores the positive perception that adolescents diagnosed with cancer hold regarding germline genetic sequencing. They articulate a strong interest in being actively involved in genetic decision-making. To address these articulated needs and preferences, we recommend the development of visually engaging counseling materials. These materials should effectively convey both the immediate and long-term implications of genetic sequencing, enabling adolescents with cancer to make informed decisions about genetic sequencing.
