ABSTRACT
Human papillomavirus (HPV)-mediated cervical carcinogenesis represents a well analyzed model of viral implication in epithelial malignant transformation. Mechanisms of high risk (HR) HPV-related infection seem to demonstrate a similar action regarding its implication in head and neck (HN) carcinomas, predominantly in squamous cell carcinoma (SCC) histological type. The prevalence of HR HPV subtypes - mainly HPV16 - is characterized by a broad geographic heterogeneity. Furthermore, HPV-associated HNSCCs demonstrate differences regarding sexual, molecular, epidemiological, and prognostic features compared to alcohol and tobacco dependent ones. Based on these differences, HPV-derived HNSCC appear to be a specific well-defined entity mostly affecting young to middle-aged - male mainly - non-smokers. This is a strong reason of detecting an increased HR-HPV DNA levels -due to viral transmission - in oropharyngeal and laryngeal anatomic regions. Additionally, different response rates to chemoradiation and targeted therapeutic regimens are another significant field for handling these SCC malignancies in the corresponding patients. In the current special article we explored the role of HPV-related carcinogenesis in oropharyngeal and laryngeal SCC focused on the latest molecular aspects.
