Abstract
Oral and laryngeal cancers exhibit overlapping clinical features but distinct genomic profiles.In a study of 60 Head and neck squamous cell carcinomas(HNSCC) cases (30 OSCC, 30 LSCC), NGS revealed TP53 mutations in 70% of oral squamous cell carcinoma (OSCC) and 83% of laryngeal squamous cell carcinoma (LSCC). CDKN2A alterations were more common in OSCC (40%) than LSCC (20%), while PIK3CA mutations were higher in LSCC (30%). NOTCH1 mutations were more frequent in OSCC (27%) than LSCC (10%). Pathway analysis showed disruptions in p53 and PI3K-Akt, with stronger enrichment in LSCC (ES: 3.42). The results suggest site-specific tumor biology influencing therapeutic targets. Molecular profiling is crucial for precision treatment in head and neck cancers.
