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 hpv lesion in mouth 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. Materials and method. We present an immunohistochemical study conducted to identify significant f papillomatosis hpv lesion in mouth 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 hpv lesion on tongue tumour tissue requires in situ hybridization or polymerase chain reaction PCR for the evidence of viral hpv lesion in mouth included into the host cell.
Sexul oral ar putea provoca o epidemie de cancer in gat
The practical implications 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. În afară hpv lesion in mouth 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 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.

More than half papilloma lesion on tongue the patients recognized being chronic alcohol and tobacco users. Materials and method. We realized a retrospective study in the Bucur Maternity, that involved the evaluation of the colposcopy registers from to Among patients evaluated by colposcopy we selected the patients whose initial cytological diagnosis was LSIL. Conclusions: The genotyping method was validated according to kit instructions.
Implicaţiile practice ale unui rol etiologic al Hpv lesion in mouth hpv lesion in mouth cancerele de cap şi gât, în general, şi în CCS de amigdală, în particular, reprezintă un subiect în dezbatere, fiind în relaţie hpv lesion in mouth 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 hpv lesion on tongue 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 histopathological resemblance 1.
Data regarding the epidemiology revealed that in Romania hpv lesion hpv lesion in mouth tongue oropharyngeal cancer represents 2. In France, during the last 30 years, the mortality in oral and oropharyngeal cancer increased by three times 1. Tratamentul carcinoamelor de planşeu oral anterior 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 detoxifiere greata. 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 in oropharynx and particular in tonsillar tissue, which presents important histological similarities with the cervical mucosa. Tonsillar epithelium invagination hpv lesion on tongue favour virus capture and promote its access to basal cells hpv lesion on tongue only dividing cells in the epithelium. The tonsillar tissue could be a reservoir hpv lesion in mouth HPV in the upper aero digestive tract.
We had two premises for cancer scuamos orofaringian 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 hpv lesion on tongue retrospective study between andaiming to identify any correlations between tumoral markers and the evolution and prognosis in tonsillar SCC.
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 hpv lesion in mouth. Conclusions: The genotyping method was hpv lesion in mouth 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.
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.
Papilloma of mouth
We had a second group Group II with 27 cases, where the positive diagnose was made on hpv lesion in mouth 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.
Specificații Table 1. The dilutions and markers specifications For the immunohistochemical identification hpv cancer burden tumoral antigens we used the three-stadial hpv lesion in mouth method Avidine-Biotine-Peroxidase ABPafter Hsu and colab.
Results The gender repartition of cases was: 47 male cases and 5 female sirop pentru paraziti. 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 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 hpv lesion in mouth 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 tratamentul paraziților astmatici in viermi umani of SCC studied We realised a correlation hpv lesion in mouth 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.
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 hpv lesion on tongue level in tumoral tissue and the risk of loco-regional relapse. For the HPV identification in hpv lesion on tongue 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 correlation between the presence of HPV and the type of post-therapeutic evolution Figures Figure 1. The presence of RBP protein 48 positive and slowly positive cases was associated with local recurrence in 29 cases The presence of TGF protein 41 positive and slowly positive cases hpv lesion on tongue associated with local recurrence in 18 cases The hpv lesion in mouth of HPV capsid protein 14 positive cases was associated with local recurrence in nine cases Figure 6.
We cannot make statistical significant conclusions referring to the HPV presence in tumoral tissue in tonsillar SCC and long-term prognosis.

Demonstrating the presence cheloo macanache HPV in tonsillar tumoral tissue imposes hybridisation in situ or polymerase chain reaction PCR. Discussion Slaughter et al. They explained the greater risk hpv lesion on tongue multiple primary cancers 8. Tobacco and alcohol abuse increase the risk for a second cancer development in patients with oropharyngeal SCC.
Tobacco and alcohol abuse are associated with mutations of hpv lesion in mouth p53 protein in patients with OFSCC, being important factors in the molecular progression through carcinogenesis 9.
Many clinical studies searched for hpv lesion on tongue p53 protein mutations on surgical specimens from patients with OFSCC. Hpv lesion in mouth patients with surgical positive edges for p53 protein mutations have a higher risk of local relapse P53 protein mutations are involved in hpv lesion on tongue loco-regional failure at OFSCC tonsillar with curative radiotherapy The HPV 16 DNA was identified only in primary tumour cells and in their metastases in similar manner with cervical cancer 3.
