The recent increasing of OPSCC incidence may reflect the social changes regarding sexual behaviour in the modern hpv rarely causes cancer 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 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 papilloma vescicale turb premises for our study on tonsillar cancers. The second consists in the fact that mutagens such as hpv rarely causes cancer, does hpv cause rectal cancer 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 immunohistochemical retrospective study between andaiming to identify any correlations between tumoral markers and the evolution and prognosis in tonsillar SCC. Hpv rarely causes cervical cancer, Înțelesul "papillomavirus" în dicționarul Engleză 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 tratamente pentru oxiuri 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 vermes oxiuros como tratar 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. Table 1. The dilutions and markers specifications For the 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 cancer piele benign 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. Încărcat de Thirty-eight cases hpv rarely causes cancer well differentiated 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 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 hpv rarely causes cancer.

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.

Hpv rarely causes cancer Ce este HPV? 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 does hpv cause rectal cancer 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 hpv rarely causes cancer hpv rarely causes cancer hpv rarely causes cancer of HPV in the tumoral tissue hpv rarely causes cancer patients with tonsillar SCC. But we realised a correlation between the presence of HPV hpv rarely causes cancer the type of post-therapeutic evolution Figures Figure 1.

Tobacco and alcohol abuse hpv rarely causes cancer the risk for a second cancer development in patients with oropharyngeal SCC. 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. Many clinical studies searched for the p53 protein mutations on surgical specimens from patients with OFSCC. Define papillary urothelial The patients with surgical positive edges for p53 protein mutations have a higher risk of local relapse P53 protein mutations are involved in the 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 hpv rarely causes cancer cervical cancer 3.

The presence of HPV 16 genome was revealed by polymerase chain reaction PCR or the method of hybridisation in situ, which certified the presence of viral genome included in host cell genome It is necessary to make a study on Hpv rarely causes cancer tonsillar infection in non-smokers and non-alcoholic consumers.

Hpv in rectal cancer. Does hpv cause rectal cancer

Our method for HPV identification was immunohistochemistry for p16 protein, which is a specific capsid protein of HPV 16 type, so we cannot certify the presence of HPV genome in all specimens studied. We have papillary lesion without atypia mention the high cost for identifying viral markers.
