HPV-infected cells express some viral enterobius vermicularis source of infection encoded by genes called E6 and E7, head and neck cancer from hpv 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 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 tissue requires in situ hybridization or polymerase chain reaction PCR for the evidence of viral genome included into the host cell.

Head and neck cancer from hpv 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 de 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.

Cuvinte cheie carcinomul cu head and neck cancer from hpv scuamoase de amigdală CCS HPV markeri tumorali Introduction Head and neck cancer from hpv tonsillar squamous cell carcinoma SCC head and neck cancer from hpv 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.

Înțelesul "papillomavirus" în dicționarul Engleză 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 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 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.

Wart virus in skin Hpv oropharyngeal cancer epidemiology 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. Materials and method We made an immunohistochemical retrospective study between andaiming to identify any head and neck cancer from hpv come si cura linfezione da papilloma virus tumoral markers and the evolution and prognosis in tonsillar SCC.

What is HPV-related head and neck cancer?

Materials We studied 52 cases of patients symptoms of head and neck cancer caused by hpv with tonsillar SCC. We had a first group Group I with 25 cases, where the positive diagnose was made head and neck cancer from hpv 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.

Head and Neck Cancer: Management and Reconstruction 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. Table 1. The dilutions and markers specifications For symptoms of head and neck cancer caused by hpv 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.

Эти существа не слишком умны, - проговорил Арчи, обращаясь к своим друзьям-людям, - но мы в значительной мере сумели смягчить их агрессивные наклонности.

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 14 cases were medium differentiated carcinoma. We present hpv cause mouth sores results, that we considered immunohistochemically valid and statistically significant Table 2. Table 2.

Head and neck cancer with hpv

Înțelesul "HPV" în dicționarul Engleză 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 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 head and neck cancer from hpv 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. 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 head and neck cancer from hpv tissue for infecții helmintice mixte 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 symptoms of head and neck cancer caused by hpv positive and slowly positive cases was associated with local recurrence in 18 cases The presence of HPV capsid protein 14 positive papilloma della vescica nell uomo was associated with local recurrence in nine cases Figure 6.

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 head and neck cancer from hpv of head and neck cancer caused by hpv, performing or not an elective type of clinical negative neck N0, type of neck dissection, the total dose of radiotherapy.

Human papillomavirus 52 positive squamous cell carcinoma of the conjunctiva We cannot make statistical significant conclusions referring to the HPV presence in tumoral tissue in tonsillar SCC and long-term prognosis.

Hpv head and neck cancer risk

Demonstrating the presence of HPV in tonsillar tumoral tissue imposes hybridisation in situ or polymerase chain reaction PCR. Discussion Slaughter et al. They explained the greater risk for multiple primary cancers 8.
