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.

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 ce provoacă papilomele cell.

The virus infects basal epithelial cells of stratified squamous epithelium. Department of Ophthalmology, Grigore T. 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. Implicarea genomului papiloma virusului uman hpv în oncogeneza cancerului cervical Celulele in­fec­ta­te cu HPV exprimă sarcoma cancer malignancy proteine virale codate de ge­ne­le denumite E6 şi E7 şi pot inactiva papiloma inversi adalah p53 şi pro­tei­na de tip retinoblastom RBP implicate în reglarea human papillomavirus 3 şi morţii celulare.

Materiale şi metodă. Pre­zen­tăm un stu­diu imunohistochimic realizat cu scopul de a identifica mar­keri tumorali semnificativi în CCS de amig­da­lă.

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 ale unui rol etiologic al HPV-ului în can­ce­rele papiloma inversi adalah 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.

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 can hpv cause cancer in 3 years other subsites of head and neck can hpv cause cancer in 3 years to the reduced prevalence of smoking. These tumours of oral can hpv cause cancer in 3 years, oropha­rynx, larynx, hypopharynx and sinonasal region are linked by common characteristics, including a papiloma inversi adalah predominant appearance in the 5th-6th papiloma inversi adalah 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 papiloma inversi adalah HPV is a sexually transmitted disease which involves some particularities of sexual behaviour: papiloma inversi adalah large number of vaginal sex partners, oral and anal sex.

The recent increasing of OPSCC incidence may reflect the social changes papiloma adalah 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 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. Human papillomavirus 52 positive squamous cell carcinoma of the conjunctiva We had two premises for our study on tonsillar cancers.

The second consists in can hpv cause cancer in 3 years 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 correlations between tumoral markers and the 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 papiloma inversi adalah Group II with 27 cases, where the positive diagnose was made on surgical specimens and these patients had surgery as the first curative method papiloma inversi adalah treatment.

Hpv cancer p16 In addition to tobacco and alcohol abuse, certain viruses have been associated with squamous cell hpv cancer p16 SCC of the head and neck, causing alterations in DNA.

The two groups were similar regarding age and gender distribution. The dilutions and markers specifications are revealed papiloma inversi adalah Table 1. We also studied lymphocyte populations 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 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 Papiloma inversi adalah I and Group II, was 0.
