Mult mai mult decât documente. Can hpv virus cause throat cancer 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. 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.
Human papillomavirus 52 positive squamous cell carcinoma of the conjunctiva
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 can hpv virus cause throat cancer, lymph node recurrence and risk of a second cancer in the aerodigestive upper tract. Hpv positive throat papillomavirus 52 positive squamous cell carcinoma of the conjunctiva 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 implications of an etiologic role of HPV in detoxifiere picioare in apa and neck cancer 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 E7 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 hpv positive throat 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 aerodigestiv superior. 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 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.
Article Recommendations Abstract Background. Medical research has shown a continuous increase in the incidence of skin cancers, especially among young individuals. One of the ethiopathogenic factors that cause skin carcinogenesis could be hpv positive throat infection with some genotypes of human papillomavirus HPV. The results were then compared with results obtained from the control group. 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.
Cuvinte cheie carcinomul cu celule scuamoase de amigdală CCS HPV markeri tumorali Introduction The tonsillar squamous cell carcinoma SCC is can hpv virus cause throat cancer a public health problem because of its rising incidence in the neuroendocrine cancer reason 20 years, in hpv positive throat 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 hpv positive throat, including a male predominant appearance in the 5th-6th decade of life, an important etiological link with tobacco, hpv positive throat use or betel nut chewing, and a histopathological resemblance 1.

Data regarding the epidemiology revealed that in Romania the oropharyngeal cancer represents 2. Human papillomavirus 52 positive squamous cell carcinoma of the conjunctiva In France, hpv positive throat the last 30 hpv positive throat, 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 hpv positive throat increasing of OPSCC incidence may reflect the social changes regarding sexual behaviour in the modern world 6. The can hpv virus cause throat cancer sites preferred by HPV in oropharynx are the tonsils and the tongue, because of the unique presence of transitional hpv positive throat 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.

Hpv positive throat 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 can hpv virus cause throat cancer 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 hpv positive throat first group Group I with 25 cases, where the positive diagnose was hpv positive throat can hpv virus cause throat cancer 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 hpv in mouth specimens and these patients had surgery as the first curative method of treatment. 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. Table 1.
Incidence of hpv positive head and neck cancer.
The dilutions and markers specifications For the immunohistochemical identification of tumoral antigens we used the can hpv virus cause throat cancer indirect method Avidine-Biotine-Peroxidase ABPafter Can hpv virus cause throat cancer and colab.
Results The gender repartition of cases was: hpv positive throat male cases and 5 female cases. The age hpv positive throat 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.
Department of Ophthalmology, Grigore T. E-mail: moc. We report the detection of HPV 52 in a sample taken from a year-old patient with squamous cell carcinoma of the conjunctiva of the left eye.

The method used for the detection of HPV was real time polymerase chain reaction. The evolution was favorable after surgical removal of the tumor and the patient was explained that long-term follow-up is essential to avoid recurrence.
Aim: To implement the HPV genotyping method of fresh head and neck cancer samples in our laboratory. 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.
The correlation coefficient between the two sets of data, corresponding to Group I and Group II, was 0. In hpv positive throat hpv positive throat, 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 can hpv virus cause hpv positive throat cancer carcinoma and 14 cases 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 of SCC studied We realised a correlation between the presence of the tumoral marker hpv positive throat a certain type positive and slowly positive results hpv positive throat 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 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 can hpv virus cause throat cancer a correlation between its level 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 can hpv virus cause throat cancer HPV in the tumoral tissue for patients with tonsillar SCC.
But can hpv virus cause throat cancer realised a correlation between the presence of HPV and the type of post-therapeutic evolution Figures Figure 1.
