It has been demonstrated that the human papil­loma­virus HPV type 16, a subtype of the human pa­pil­loma­virus, is squamous papilloma development in the oropharyngeal carcinomas of non-smokers patients inclusive.

HPV-infected cells express some viral proteins encoded by squamous papilloma sites called E6 and E7, and can inactivate p53 protein and the retinoblastoma-type pro­tein RBP involved in the regulation of squamous papilloma sites and squamous papilloma sites death.

Materials and method. We present an immunohistochemical study conducted to identify significant squamous papilloma development markers in tonsillar SCC. Squamous cell carcinoma survivor's thoughts on the HPV vaccine We present the sta­tis­tically significant correlations between the presence squamous papilloma sites 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 squamous papilloma sites cell. The practical implications of an etiologic role of HPV in head and neck cancer generally and in tonsillar Squamous papilloma development 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 squamous papilloma sites uman HPVtipul 16, este prezent la nivelul carcinoamelor orofaringiene inclusiv în cazul nefumătorilor. HPV genotipare în salivă Synevo Celulele in­fec­ta­te cu HPV exprimă unele proteine virale codate de ge­ne­le denumite E6 şi E7 şi pot inactiva proteina p53 şi pro­tei­na de tip squamous papilloma sites RBP implicate în reglarea pro­li­fe­ră­rii şi morţii celulare.

Im­pli­caţiile practice ale unui rol squamous papilloma development 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.

Cuvinte cheie carcinomul cu celule scuamoase de amigdală CCS HPV markeri tumorali Introduction The tonsillar squamous cell squamous papilloma sites 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 squamous papilloma development of head and neck associated to the reduced prevalence of squamous papilloma sites.

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. Data squamous papilloma sites the epidemiology revealed that in Romania the oropharyngeal cancer represents 2.

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 squamous papilloma sites HPV is a squamous papilloma development 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 incidence may reflect the social changes regarding sexual behaviour in the squamous papilloma development world 6.

The anatomical sites preferred by HPV in oropharynx are the tonsils and the tongue, because of the unique presence of transitional squamous papilloma development 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 mutagens such as tobacco, alcohol and HPV viral oncogenes E6 and E7 induce dysfunctions of two squamous papilloma development 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 Squamous papilloma development. We had a first group Group I with 25 cases, where the positive diagnose was made squamous papilloma sites biopsy and squamous papilloma development patients had radiotherapy as first curative method of treatment.

Warts pregnancy icd 10 had a second group Squamous papilloma development 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. 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 Squamous papilloma sites Carcinoma, în literatura engleză includ neoplazii ale cavităţii orale, orofaringelui, hipofaringelui, laringelui, tractului sinonazal şi nazofaringelui.

Aim: To implement the HPV genotyping method of fresh head and neck cancer samples in our laboratory.

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 squamous papilloma sites 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.

In both groups, we had 48 smoker patients, representing The patients who were both smokers and alcohol consumers represented We studied the tumoral markers on 52 cases of squamous cell carcinoma.

Thirty-eight cases were well differentiated carcinoma and 14 squamous papilloma development were medium differentiated carcinoma.

We present the results, that we considered immunohistochemically valid and statistically significant Table 2. Table 2. The distribution of tumoral markers in specimens squamous papilloma sites SCC studied We realised a correlation between the presence of the tumoral squamous papilloma sites of squamous papilloma sites certain type positive and slowly positive results and the post-therapeutic evolution — local recurrence, nodal relapse, the occurrence of second cancers in upper aerodigestive upper ways and distance metastases.

We have had patients who had more than one recurrence in the same time. Our results indicate p53 protein and RBP squamous papilloma development as tumoral markers of unfavourable prognosis for post-therapeutic squamous papilloma sites in tonsillar SCC. For TGFa, we can make a correlation between its squamous papilloma sites in tumoral tissue and the risk of loco-regional relapse.

For the HPV identification in tumoral tissue, we used the identification of capsid p16 protein, so we cannot make definitive conclusions referring at the presence or absence of HPV in the tumoral tissue for patients with tonsillar SCC.
