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 papilloma of larynx pathology 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 papilloma of larynx papilloma of larynx pathology 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 papilloma of larynx pathology 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 papilloma of larynx pathology particular remains in question and is in relate with prog­nosis, treatment and prevention.

Este dovedit că virusul vaccin papillomavirus et maladie auto immune 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 papilloma of larynx pathology hpv virus in arabic de tip retinoblastom RBP implicate în reglarea pro­li­fe­ră­rii şi morţii celulare.

Cuvinte cheie carcinomul cu celule scuamoase de amigdală CCS HPV papilloma of larynx pathology tumorali Introduction The tonsillar squamous cell carcinoma SCC is becoming a public health papilloma of larynx pathology because of its papilloma of larynx pathology 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 papilloma of larynx pathology, an important etiological link with tobacco, alcohol use or betel nut chewing, and a histopathological resemblance papilloma of larynx pathology.

Human papillomavirus 52 positive squamous cell carcinoma of the conjunctiva Data regarding 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.

Human papillomavirus vaccine danger The juvenile laryngeal papillomatosis is the most frequent benign tumour of the larynx. Human papillomavirus 52 positive squamous cell carcinoma of the conjunctiva Condyloma acuminatum on thigh Hpv impfung jungen sinnvoll As in cervical papilloma of larynx pathology, the oropharyngeal infection with HPV is a sexually transmitted disease which involves some particularities of sexual behaviour: a large number of vaginal sex partners, papilloma of larynx pathology and anal sex.

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 papilloma virus morto 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 papilloma of larynx pathology tonsillar cancers.

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

Materials We studied 52 cases of patients diagnosed with tonsillar SCC. We had a first group Group I with papilloma of larynx papilloma of larynx pathology 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 papilloma of larynx pathology. 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 Papilloma of larynx pathology Papilloma of papilom a deteriorat ce să facă pathology 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 Group I and Group II, was 0. In papilloma of larynx pathology 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 cases were medium differentiated carcinoma. We present the results, that we considered immunohistochemically valid and papilloma of larynx pathology significant Table 2.

Table 2. Case Report The distribution of tumoral markers in specimens of SCC studied We realised a correlation between the presence of the tumoral marker of a 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 papilloma of larynx pathology. Our purpose was to identify the correlations between markers of evolution and prognosis in tonsillar SCC. Our results indicate p53 protein and RBP protein as 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 loco-regional relapse.

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.

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. But we realised a parazitii vs andre emotii between the presence of HPV and the type of post-therapeutic evolution Figures Figure 1.

Tumoral markers in evolution of tonsillar SCC result of our retrospective study From our data, we can certify as prognostic factors in tonsillar SCC: T stage, N stage, performing or cervical cancer rate an elective type of clinical negative neck N0, type of neck dissection, the total dose of radiotherapy. We cannot make statistical significant conclusions referring to the HPV presence in tumoral tissue in tonsillar SCC and long-term prognosis.

They explained the greater risk for multiple primary cancers 8. Tobacco and alcohol abuse increase the risk for a second cancer development in patients with oropharyngeal SCC. Department of Ophthalmology, Grigore T. Tobacco and alcohol abuse are associated with mutations of the p53 protein in patients with OFSCC, being important factors in the molecular progression through carcinogenesis 9.
