An increased risk of HPV+OPC is observed more than 15 years after HPV exposure, [8] pointing to a slow development of the disease, similar to that seen in cervical cancer. Relative to HPV-OPC, the oncogenic molecular progression of HPV+OPC is poorly understood. [28] The two main viral oncoproteins of the high risk HPV types are E6 and E7.
Oropharyngeal cancer, [1] [2] [3] also known as oropharyngeal squamous cell carcinoma and tonsil cancer, [1] is a disease in which abnormal cells with the potential to both grow locally and spread to other parts of the body are found in the oral cavity, in the tissue of the part of the throat that includes the base of the tongue, the tonsils, the soft palate, and the walls of the pharynx.
A common symptom of laryngeal papillomatosis is a change in voice quality. More specifically, hoarseness is observed. [4] [5] As a consequence of the narrowing of the laryngeal or tracheal parts of the airway, shortness of breath, chronic cough and stridor (i.e. noisy breathing which can sound like a whistle or a snore), can be present.
HPV-positive oropharyngeal cancer generally has a better outcome than HPV-negative disease, with a 54% better survival rate, [18] but this advantage for HPV-associated cancer applies only to oropharyngeal cancers. [19] People with oropharyngeal carcinomas are at high risk of developing a second primary head and neck cancer. [20]
Laryngeal cancer or throat cancer is a kind of cancer that can develop in any part of the larynx (voice box). It is typically a squamous-cell carcinoma, reflecting its origin from the epithelium of the larynx. The prognosis is affected by the location of the tumour.
Human papillomavirus (HPV)-associated oropharyngeal cancer awareness and prevention is a vital concept from a public and community health perspective. HPV is the sexually transmitted virus that is known to be the cause of genital warts. There are currently more than 100 different strains of HPV, half of which can cause genital infections. [1]
Squamous cell papilloma of the mouth or throat is generally diagnosed in people between the ages of 30 and 50, [1] and is normally found on the inside of the cheek, on the tongue, or inside of lips. Oral papillomas are usually painless, and not treated unless they interfere with eating or are causing pain. [ 1 ]
Cervical cancer was the most frequent HPV-associated cancer with on average 292 cases per year (74% of the female total, and 54% of the overall total of HPV-associated cancers). [196] A study of 996 cervical cytology samples in an Irish urban female, opportunistically screened population, found an overall HPV prevalence of 19.8%, HPV 16 at 20% ...
