Abstract
Head and neck sarcomas (HNS) are rare, heterogeneous malignancies representing less than 1% of head and neck cancers. Their complex anatomy and overlapping morphologies pose significant challenges for traditional diagnosis. We aimed to evaluate the clinical utility of next-generation sequencing (NGS) within a tertiary referral centre and synthesise these findings with current global molecular standards. We conducted a retrospective review of an original, previously unpublished, cohort of 12 patients with histologically verified HNS treated at University College London Hospital (UCLH) between 2023 and 2024. Molecular profiling included targeted DNA (RMH200) and RNA-fusion panels. This was supplemented by a qualitative synthesis of 16 key studies (2010-2026) identified through a systematic search strategy. In the institutional cohort, NGS provided definitive diagnostic or therapeutic clarification in 66% of cases (8/12). Key findings included the identification of pathognomonic fusions (such as EWSR1::FLI1, PAX3::MAML3), a novel MAMLD1::VGLL3 fusion, and actionable variants such as BRAF V600E and MYOD1. Furthermore, the formal exclusion of Neurotrophic tropomyosin receptor kinase (NTRK) fusions in some cases allowed for therapeutic streamlining. Literature synthesis aligned these results and emphasised the need for NGS for more accurate diagnosis and adequate treatment. NGS is a clinical necessity in the management of ultra-rare HNS. By transitioning from traditional morphology to high-resolution molecular interrogation, clinicians can resolve diagnostic ambiguity and identify targeted therapeutic pathways. Integration with emerging 2026 standards, including epigenetic classification and liquid biopsy monitoring, represents the future of precision surgery in head and neck sarcoma.
