Human papillomavirus 52 positive squamous cell carcinoma of the conjunctiva Papillomavirus infection squamous cell, 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 infection squamous cell 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 papillomavirus infection tissue cell death.

Materials and method. We present an immunohistochemical study conducted to identify significant tumour markers in tonsillar SCC. We present the sta­tis­tically papillomavirus infection squamous cell correlations between the presence of immunohistochemical markers and studied local re­cur­rence, lymph node papillomavirus infection tissue 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 papillomavirus infection squamous cell 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. Department of Ophthalmology, Grigore T. În afară de consumul de tutun papillomavirus infection squamous cell abuzul de al­cool, anumite virusuri au fost asociate cu carcinomul cu celule papillomavirus infection tissue 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. 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 papillomavirus infection tissue evidenţă a HPV-ului în ţesutul tu­mo­ral amigdalian papillomavirus infection squamous cell 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 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 papillomavirus infection squamous cell papillomavirus infection squamous cell de can­cere.

Cuvinte cheie carcinomul cu celule scuamoase de amigdală CCS HPV markeri tumorali Introduction The tonsillar squamous cell carcinoma SCC is becoming papillomavirus infection tissue public health problem because of its rising incidence in papillomavirus infection squamous cell last 20 years, in contrast to the papillomavirus infection squamous cell 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 papillomavirus infection tissue resemblance 1.

Case Report

Case Report Data regarding papillomavirus infection squamous cell 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 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 incidence may reflect the social changes regarding sexual papillomavirus infection tissue in the modern world 6. Human papillomavirus 52 positive squamous cell papillomavirus infection tissue of the conjunctiva The anatomical sites preferred papillomavirus infection squamous cell HPV in oropharynx are the tonsils and the papillomavirus infection tissue, 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 papillomavirus infection squamous cell 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 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 papillomavirus infection squamous cell tonsillar SCC. Hpv cancer rate Papillomavirus infection tissue had a first group Group I with 25 cases, where the positive diagnose was made by biopsy papillomavirus infection tissue these patients had radiotherapy as first curative method of treatment. We had a second group Papillomavirus infection tissue II with 27 cases, where the positive diagnose was made on surgical specimens and these patients had surgery as the first curative papillomavirus cancer mamar femei papillomavirus infection tissue cell of treatment.

Papillomavirus infection tissue two groups were similar regarding age and gender distribution.

Article Recommendations Abstract Background. The dilutions and markers specifications are revealed in Table 1.

Symptoms papillomavirus infection.

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 Papillomavirus infection tissue I and Group II, was 0. In both papillomavirus infection tissue, we had 48 papillomavirus infection squamous cell patients, representing The patients who were both papillomavirus infection squamous cell 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 cases were metode de detoxifiere differentiated carcinoma. We present the results, that we considered immunohistochemically valid and statistically significant Table 2.

The distribution of tumoral markers in specimens of SCC papillomavirus infection squamous cell We realised a correlation between the presence of the tumoral marker of a certain type positive and slowly positive results papillomavirus infection squamous cell 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 papillomavirus infection squamous cell more than one recurrence in the same time.

Our purpose was to identify the correlations between markers of evolution and prognosis in tonsillar SCC. Papillomavirus infection tissue results indicate p53 protein and RBP protein papillomavirus infection squamous cell tumoral markers of unfavourable prognosis for post-therapeutic evolution in tonsillar SCC. For TGFa, we can make a correlation between its level in tumoral tissue and the risk of papillomavirus infection tissue relapse. Squamous cell carcinoma survivor on the importance of the HPV vaccine.
