Comment from the Editor on the Special Issue "Head and Neck Critical Illness: Basic and Clinical Research Implications".

While oncogenic mutations of head and neck squamous cell carcinomas (HNSCC) in head and neck malignancies are uncommon, analysis using next-generation sequencing (NGS) technologies is growing. Further, single-cell analysis is being developed to overcome cancer cell heterogeneity and improve the poor survival of patients. However, it is important for researchers to know how to use this information to improve patients' survival.
