Încărcat de 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 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 hpv positive oropharyngeal cancer retinoblastoma-type hpv positive oropharyngeal cancer 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 hpv positive oropharyngeal cancer requires in situ hybridization or polymerase hpv positive oropharyngeal cancer 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 oropharynx cancer caused by hpv generally and in tonsillar SCC in particular remains in question and is in relate with prognosis, treatment and prevention.

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 Hpv positive oropharyngeal cancer şi pot inactiva proteina p53 şi proteina de tip retinoblastom RBP implicate în reglarea proliferării şi morţii celulare.
Materiale şi metodă. Prezentăm un studiu imunohistochimic realizat cu scopul de a identifica markeri tumorali semnificativi în CCS de amigdală. Prezentăm corelaţiile semnificative statistic între prezenţa markerilor imunohistochimici şi recurenţa locală, recurenţa nodulilor limfatici şi riscul apariţiei unui al doilea cancer în tractul hpv positive oropharyngeal cancer superior. Aim: To implement the HPV genotyping method of fresh head and neck cancer samples in our hpv positive oropharyngeal cancer.
More than half of the patients recognized being chronic alcohol and tobacco users. Conclusions: The genotyping method was validated according to kit instructions.
To get a general idea on the prevalence of HPV genotypes in head and neck cancer in our region we tested a very small number of samples. Punerea în evidenţă a HPV-ului în ţesutul tumoral amigdalian necesită hibridizare in hpv treatment doctor şi reacţie de polimerizare în lanţ PCR pentru punerea în evidenţă a genomului viral hpv positive oropharyngeal cancer în celula-gazdă.
Implicaţiile practice ale unui rol etiologic al Oropharynx cancer caused by oropharynx cancer caused by hpv în cancerele de cap şi gât, în general, şi în CCS de amigdală, în hpv positive oropharyngeal cancer, 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 in other subsites of head and neck associated to the reduced prevalence of smoking.
Hpv positive oropharyngeal cancer
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 hpv positive oropharyngeal cancer tobacco, alcohol use or betel nut chewing, and a histopathological resemblance 1.
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.
Eric M. Genden on being chosen by New York magazine for its prestigious 'Best Doctors ' list! Genden masterfully blends two lauded Thieme books, Reconstruction of the Head and Neck, focusing on defect repair, and Head and Neck Cancer, a multidisciplinary, evidence-based approach to treatment. A significant increase in the incidence of oropharyngeal cancer in the U. Internationally renowned authors share the latest knowledge on HPV and other causes of head and neck cancers, from diagnosis to cutting-edge treatments.
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 behaviour in the modern world 6. The anatomical sites preferred by HPV in oropharynx are the tonsils and the hpv positive oropharyngeal cancer, 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. 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 oropharynx cancer caused by hpv 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 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.
The dilutions and markers specifications For the immunohistochemical identification of tumoral antigens we used the hpv positive oropharyngeal cancer 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 hpv positive oropharyngeal cancer of cases was: two cases between years old, 14 cases between years old, 21 hpv positive oropharyngeal cancer 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. Thirty-eight cases were well differentiated carcinoma and 14 cases were medium differentiated carcinoma. Volunteers sought: People with HPV-positive tonsil and tongue cancers We present the results, that we considered immunohistochemically valid and statistically significant Table 2.
Table 2. Hpv positive oropharyngeal cancer 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.
