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 human papillomavirus on the tongue regulation of proliferation and cell death.

Materials and method. We present an immunohistochemical study conducted to identify significant tumour markers in human papillomavirus infection tongue SCC. We present the sta­tis­tically significant correlations between the presence of immunohistochemical markers and studied local re­cur­rence, lymph node recurrence and human papillomavirus infection tongue 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 of 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.

Cuvinte cheie carcinomul cu celule scuamoase de amigdală CCS HPV markeri tumorali Introduction The tonsillar squamous cell carcinoma SCC is becoming a public health human papillomavirus infection tongue papillomavirus infection tongue 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 a male predominant appearance in the 5th-6th decade of life, an important etiological link with tobacco, alcohol use or betel nut chewing, and a histopathological resemblance 1.

In France, during the last 30 years, the mortality in oral and oropharyngeal cancer increased by three times 1. As in cervical cancers, the oropharyngeal infection with HPV is a human papillomavirus on the tongue transmitted disease which involves some particularities of sexual behaviour: a large number of vaginal sex partners, human papillomavirus infection tongue and anal wart on foot burning sensation. The recent increasing of OPSCC incidence may reflect the social changes regarding sexual behaviour in the modern world 6.

The anatomical sites preferred by HPV in oropharynx are the tonsils and the tongue, because of the unique presence of transitional mucosa in human papillomavirus on the tongue and particular in tonsillar tissue, which curatarea ficatului cu sare amara important histological similarities with the cervical mucosa. Specificații Tonsillar epithelium invagination may favour virus capture and promote its access to basal cells the only dividing human papillomavirus infection tongue in the epithelium.

The tonsillar tissue could be a reservoir for HPV in the upper aero digestive tract. We had human papillomavirus on the tongue premises for our study on tonsillar cancers.

The second consists in the fact that mutagens such as tobacco, alcohol and HPV viral oncogenes E6 and E7 induce dysfunctions of two major mechanisms of cellular cycle, which involves the p53 and RBP tumoral suppressor genes 2. Materials and method We made an immunohistochemical retrospective study between andaiming to identify any human papillomavirus infection tongue between tumoral markers and human papillomavirus on the tongue evolution and prognosis in tonsillar SCC.

Materials We studied 52 cases 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.

We had a second group Group II with 27 cases, where the positive diagnose 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 populations CD4, CD8, and populations of dendritic cells in tumour tissue.

Results The gender repartition of cases was: 47 male cases and 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 two sets of data, corresponding to Group I and Group II, was 0.
