Retrospective study reveals actionable alterations in 70% of pediatric soft tissue sarcomas, highlighting enhanced diagnostic accuracy and targeted treatment options.

Key Points

To evaluate the diagnostic and clinical impact of comprehensive molecular profiling using next-generation sequencing in pediatric soft tissue sarcomas.
Retrospectively analyzed 55 frozen tumor samples representing 24 distinct soft tissue sarcoma subtypes from a pediatric oncology biobank.
Performed next-generation sequencing using the Oncomine Childhood Cancer Research Assay panel to detect gene fusions, single nucleotide variants (SNVs), copy number variations (CNVs), and insertions/deletions (InDels).
Identified clinically relevant molecular alterations in 70% (37/55) of cases, consisting of 18 fusion transcripts, 13 SNVs, 8 CNVs, and 6 InDels.
Detected recurrent diagnostic fusions (such as BCOR::CCNB3, CIC::DUX4, and NTRK3 rearrangements), gene amplifications (PDGFRA, FGFR1, GLI1, CDK4, ERBB3, KIT), and pathogenic variants in genes including TP53, NF1, DICER1, SMARCA4, PTEN, and PIK3CA.
Enabled definitive molecular reclassification of histologically ambiguous or inaccurate diagnoses into distinct, genetically defined sarcoma entities with actionable therapeutic targets.
