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 cancer hpv oropharynx 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.

Materials and method. We present an immunohistochemical study conducted to identify significant tumour markers in tonsillar SCC. We 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 cancer hpv oropharynx an etiologic role of HPV in head and neck cancer generally and in tonsillar SCC in particular remains in question cancer hpv oropharynx 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 Cancer hpv cancer hpv oropharynx 16, este prezent la nivelul carcinoamelor orofaringiene inclusiv în cazul nefumătorilor. Celulele in­fec­ta­te cu HPV exprimă unele proteine virale codate de ge­ne­le denumite E6 şi E7 şi pot inactiva proteina p53 şi pro­tei­na de tip retinoblastom RBP implicate în reglarea pro­li­fe­ră­rii şi morţii celulare.

Punerea în evidenţă a HPV-ului în ţesutul tu­mo­ral amigdalian necesită hibridizare in situ şi reacţie de polimerizare în lanţ PCR pentru punerea în evidenţă a genomului viral conţinut în celula-gazdă. Im­pli­caţiile practice cancer vezica urinara manifestari unui rol etiologic al HPV-ului în can­ce­rele de cap şi gât, în general, şi în CCS de amigdală, în par­ti­cu­lar, reprezintă un subiect în dezbatere, fiind în relaţie cu prog­nos­ticul, tratamentul şi prevenţia acestor tipuri de can­cere.

Synevo HPV genotipare în salivă Lei Informaţii generale şi recomandări Cancerele capului şi gâtului — în majoritatea cazurilor carcinoame cu celule scuamoase HNSCC — Head and Neck Squamous Cell Carcinoma, în literatura engleză includ neoplazii ale cavităţii orale, orofaringelui, hipofaringelui, laringelui, tractului sinonazal şi nazofaringelui. În India constituie cea mai frecventă formă de cancer. Cu toate acestea, în ultima decadă, date clinice şi epidemiologice au documentat asocierea dintre infecţia HPV papiloma virus uman a cavităţii orale şi OSCC2;3;4;5.

Cuvinte cheie carcinomul cu cancer hpv oropharynx scuamoase de amigdală CCS Cancer hpv oropharynx 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 cancer hpv oropharynx 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 a male predominant appearance in the 5th-6th decade of life, an cancer hpv oropharynx etiological link with tobacco, alcohol use or betel nut chewing, and a histopathological resemblance 1.

Data regarding the epidemiology revealed that in Romania the oropharyngeal cancer represents 2. In France, during the last 30 cancer hpv oropharynx, the mortality in oral and oropharyngeal cancer increased by three times 1.

As in cervical cancers, the oropharyngeal infection with HPV is a sexually transmitted disease which involves some particularities of sexual behaviour: a large number of vaginal sex partners, oral and anal sex. The recent increasing of OPSCC cancer hpv oropharynx may reflect the social changes regarding sexual behaviour in the hpv finger wart world 6.

According to some recent studies, the HPV infection may also increase cancer hpv oropharynx risk of cardiovascular diseases. Strains of HPV 16 and 18 are strains with a high cancer risk, known to cause almost all cases of cervical cancer while also increasing the risk to develop oropharyngeal cancer[3]. Structura HPV women. Fig 1. Structure of HPV According to the CDC The Center for Disease Control and Prevention statistics from cancer hpv oropharynx United States of America, the genital HPV poate crete riscul de dezvoltare a mai multor infection is the most frequent STI sexually tipuri de cancer, precum cancerul colului uterin, transmitted infection ; this is because those over penisului, vaginului, anusului sau orofaringelui 40 types which may infect the genital region partea oral a faringelui [2].

The anatomical sites preferred cancer hpv oropharynx 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. Tonsillar epithelium invagination may favour virus capture and promote its access to basal cells the only dividing cells in the epithelium.

The tonsillar tissue could be a reservoir for HPV in the upper aero digestive tract.

We had two premises for our study on tonsillar cancers. The second consists in the fact that cancer hpv oropharynx such as tobacco, alcohol and HPV viral oncogenes E6 and E7 induce dysfunctions of two major mechanisms of cellular cycle, cancer hpv oropharynx involves the p53 and RBP tumoral suppressor genes 2.

Materials and method We made an immunohistochemical retrospective study between andaiming to identify any correlations between tumoral markers and the evolution and prognosis in tonsillar SCC. Materials We studied 52 cancer hpv oropharynx of patients diagnosed with tonsillar SCC. We had a first group Group I with 25 cases, where the positive diagnose was made by biopsy and these patients had radiotherapy as first curative method of treatment.

cancer hpv oropharynx We had a second group Group II with 27 cases, where the positive cancer hpv oropharynx was made on surgical specimens and these patients had surgery as the first curative method of treatment.

The two groups were similar regarding age and gender distribution.

The dilutions and markers specifications are revealed in Table 1. We also studied lymphocyte cancer hpv oropharynx CD4, CD8, and populations of dendritic cells in tumour tissue.

Table 1. The dilutions and markers specifications For the immunohistochemical identification of tumoral antigens we used the three-stadial indirect method Avidine-Biotine-Peroxidase ABPafter Hsu and colab. Results The gender repartition of cases was: 47 male cases cancer hpv oropharynx 5 female cases.

The age repartition of cases was: two cases between years old, 14 cases between years old, 21 cases between years old, 10 cases between years old, and five cases between years old.

The correlation coefficient between the cancer hpv oropharynx sets of data, corresponding to Group I and Group II, was 0. In both groups, we had 48 smoker patients, representing
