Family-Based Whole-Genome Sequencing to Identify Cancer Risk in Children and Adolescents Newly Diagnosed with Cancer

What this Trial Is About

Researchers are investigating the usefulness of family-based whole-genome sequencing WGS to identify cancer predisposition syndromes CPS in children and adolescents newly diagnosed with cancer. These syndromes are caused by inherited mutations in cancer predisposition genes and are linked to a higher risk of developing certain cancers. The study aims to understand how often CPS occurs in this population and the impact of germline sequencing on patients and their families. This is a multicenter prospective observational study focusing on clinical benefits and utility of WGS compared to traditional clinical information. Participants will undergo family-based germline whole-genome sequencing to identify genetic variants related to cancer predisposition. The results will be discussed in multidisciplinary meetings, and referrals to Cancer Genetics Clinics for further evaluation and genetic counseling may be recommended. Additionally, the study includes a psychosocial component to assess how the sequencing process affects patients and their families. The study follows patients for up to five years to analyze psychological impact and cost-effectiveness. During the study, researchers will collect detailed family cancer histories and monitor genetic findings, including inherited and new mutations. The primary outcome measures focus on comparing the detection of CPS by WGS versus clinical factors over two years. Secondary outcomes include mutation types, test turnaround times, surveillance adherence, and psychological effects assessed over five years. Participants will be closely followed to evaluate diagnostic accuracy, genetic counseling outcomes, and the broader impact of sequencing on care and family well-being.
