Head and neck cancer (HNC) includes various malignancies represents the seventh most common worldwide. The early diagnosis of HNC results in a 70-90% five-year survival rate, which declines with locally advanced stages disease. Current care employs multimodal strategy encompassing surgery, radiation therapy (RT), chemotherapy, immunotherapy, while treatment options vary according to stage, tumor features, patient characteristics. About 75% patients will benefit from RT, either as primary or adjuvant following surgical resection. Technological improvements such intensity-modulated RT (IMRT) image-guided (IGRT), have enhanced targeting minimized adjacent healthy tissue irradiation also expanding recurrent metastatic setting. Innovative therapeutic strategies for integrate gene therapy, molecular targeted photodynamic photothermal nanoparticles (NPs), objective optimizing control reducing damage normal tissues.
