The cause of cancer in children and adolescents remains largely unknown and a genetic susceptibility is considered in up to 10% of the cases, but most likely this is an underestimation. Families with multiple pediatric cancer patients are rare and strongly suggestive for an underlying predisposition to cancer. The absence of identifiable mutations in known cancer predisposing genes in such families could indicate undiscovered heritability. To discover candidate susceptibility variants, whole genome sequencing was performed on germline DNA of a family with two children affected by Burkitt lymphoma. Using an inheritance-based filtering approach, 18 correctly segregating coding variants were prioritized without a biased focus on specific genes or variants. Two variants in <i>FAT4</i> and <i>DCHS2</i> were highlighted, both involved in the Hippo signaling pathway, which controls tissue growth and stem cell activity. Similarly, a set of nine non-coding variants was prioritized, which might contribute, in differing degrees, to the increased cancer risk within this family. In conclusion, inheritance-based whole genome sequencing in selected families or cases is a valuable approach to prioritize variants and, thus, to further unravel genetic predisposition in childhood cancer.</p>","PeriodicalId":19746,"journal":{"name":"Pediatric Hematology and Oncology","volume":null,"pages":null},"PeriodicalIF":1.7,"publicationDate":"2023-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9437132","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Semi-structured interviews were conducted with 15 pediatric oncologists (66.7% women, aged 44.7 years on average). Interviews were audio-recorded and a thematic content analysis was conducted. Announcements of drug resistance are stressful, as they are not well codified, difficult to anticipate, and pediatric oncologists have many issues about how best to behave and which words to choose. The majority of them believe that the severity, or even the incurability of the disease, and the offer of a therapeutic alternative are essential components of the information to pass on. Pediatric oncologists describe how they adapt their communication to each family, particularly in relation to parents' questions, and also to their reactions during the announcement. They also need to adapt to the prior acquaintance they may have with the families, and to previous exchanges. Finally, pediatric oncologists acknowledge their subjectivity when estimating the parents need in terms of information.
