Comentarii Thieme congratulates Dr. Hpv tongue warts In addition to tobacco and alcohol abuse, certain viruses have been associated with squamous cell carcinoma SCC of the head and neck, causing alterations in DNA. It has been demonstrated that the human papil­loma­virus HPV type 16, a subtype of the human pa­pil­loma­virus, is present in the oropharyngeal carcinomas of non-smokers patients inclusive.

Materials and method.

Case Report We present incidence of hpv related head and neck cancer immunohistochemical study conducted to identify significant tumour markers in tonsillar SCC. Hpv head and neck cancers present the sta­tis­tically significant correlations between the presence of immunohistochemical markers and studied local re­cur­rence, lymph node recurrence and risk of a second can­cer in the aerodigestive upper tract.

The de­mon­stration of HPV in tonsillar tumour tissue requires in situ hybridization or polymerase chain reaction PCR for the evidence of viral genome included into the host cell.

The practical implications of an etiologic role hpv head and neck cancer statistics HPV in head and neck cancer generally and in tonsillar SCC in particular remains in question and is in relate with prog­nosis, treatment and prevention. În afară de consumul de tutun şi abuzul de al­cool, anumite virusuri au fost asociate cu carcinomul cu celule scuamoase CCS al capului şi gâtului, cauzând al­te­rări la nivelul ADN-ului.

Este dovedit că virusul papiloma uman HPVtipul 16, este prezent la nivelul carcinoamelor orofaringiene inclusiv în cazul nefumătorilor.

Im­pli­caţiile practice ale unui rol etiologic al HPV-ului în can­ce­rele negi indepartate complet cap şi gât, în general, şi în CCS de amigdală, în par­ti­cu­lar, reprezintă un subiect în dezbatere, fiind hpv head and neck cancer statistics relaţie cu prog­nos­ticul, tratamentul şi prevenţia acestor tipuri de can­cere. Introduction Cuvinte cheie carcinomul cu celule scuamoase de amigdală CCS HPV markeri tumorali Introduction The tonsillar squamous cell carcinoma SCC is becoming a public health problem because of its rising incidence in the last 20 years, in contrast to the decreasing incidence of carcinomas in other subsites of head and neck associated to the reduced prevalence of smoking.

These tumours of oral cavity, oropha­rynx, larynx, hypopharynx and sinonasal region are linked by common characteristics, including incidence of hpv related head and neck cancer male predominant appearance in the 5th-6th decade of life, an important etiological link with tobacco, incidence of hpv related head and neck cancer use or betel nut chewing, and a histopathological resemblance 1. Data regarding the epidemiology revealed that in Romania the oropharyngeal cancer represents 2.

Hpv head and neck cancer survival rates

In France, during the last 30 years, hpv head and neck cancer statistics mortality in oral and oropharyngeal cancer increased by three times 1. As in cervical cancers, the oropharyngeal infection with HPV is a hpv head and neck cancers transmitted disease which involves some particularities of sexual behaviour: a hpv head and neck cancer statistics number of vaginal sex partners, termeni de tratament pentru paraziți and anal sex.

The anatomical sites preferred by HPV in oropharynx are the tonsils and the tongue, because of the unique presence of transitional mucosa in oropharynx and particular in tonsillar tissue, which presents important histological similarities with the cervical mucosa.

In addition to tobacco and alcohol abuse, certain viruses have been associated with squamous cell carcinoma SCC of the head and neck, causing alterations in DNA. It has been demonstrated that the human papil­loma­virus HPV type 16, a subtype of the human pa­pil­loma­virus, is present in the oropharyngeal carcinomas of non-smokers patients inclusive. HPV-infected cells express some viral proteins encoded by genes called E6 and E7, and can inactivate p53 protein and the retinoblastoma-type pro­tein RBP involved in the regulation of proliferation and cell death.

Hpv oropharyngeal cancer statistics Tonsillar hpv head and neck cancer statistics invagination may favour virus capture and promote its access to basal cells the only dividing cells in the epithelium.
