Targeted DNA Sequencing for Tailored Therapies in Children with Extracranial Solid Tumors.

ABSTRACT: Next-generation sequencing (NGS) is instrumental for clinical decisions on molecularly targeted therapy (TT). In pediatric oncology, TT is a relatively rare choice administered chiefly on a tumor-agnostic basis. The investigation enrolled 304 pediatric patients with extracranial solid tumors that were diagnosed and treated in 2018-2023. Tumor DNA was sequenced using a customized QiaSeq panel (Qiagen, Hilden, Germany) of genes known to be relevant for pediatric solid tumors, including ALK, BRAF, BRCA1/2, EGFR, FGFR1, KIT, MAP2K1/2, NF1, PDGFRA/B, PIK3CA, PTEN, PTPN11, RAS family genes, etc. The assay allowed detection of nucleotide substitutions and small insertions/deletions, as well as gene copy number alt
