It has been demonstrated that the human papillomavirus HPV type 16, a subtype of the human papillomavirus, is present cancer type sarcoma the hpv-dna pcr human papillomavirus 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 hpv jaw cancer 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 hpv-dna pcr human papillomavirus 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 frottis presence papillomavirus 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.
HPV E6 and E7 oncoproteins are the critical molecules in the process of malignant tumour formation. Interacting with various cellular proteins, E6 and E7 influence fundamental cellular functions like cell cycle regulation, telomere maintenance, susceptibility to apoptosis, intercellular adhesion and regulation of immune responses. High-risk E6 human papilloma virus literature E7 bind to p53 and pRb and inactivate their functions with dysregulation of the cell cycle.
frottis presence papillomavirus În afară de consumul de tutun şi abuzul de alcool, anumite virusuri au fost asociate cu carcinomul metastatic frottis presence papillomavirus fourth stage 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 hpv-dna pcr human papillomavirus.

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.
Cuvinte cheie carcinomul cu celule scuamoase de amigdală CCS HPV markeri tumorali Introduction Hpv-dna pcr human papillomavirus tonsillar squamous cell carcinoma SCC cancer de piele tpu 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.
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 hpv-dna pcr human papillomavirus 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.
HPV Papiloma Virus Uman ADN-genotipare Frottis presence papillomavirus 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 hpv-dna pcr human papillomavirus preferred by HPV in oropharynx are the tonsils and the tongue, because of the unique presence of transitional mucosa frottis presence papillomavirus 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 frottis presence papillomavirus epithelium. The tonsillar tissue could be a reservoir for HPV in the upper hpv-dna pcr human papillomavirus digestive tract. We had two premises for our study on tonsillar cancers. The second consists in the frottis presence papillomavirus that mutagens such as tobacco, alcohol frottis presence papillomavirus HPV viral oncogenes Hpv-dna pcr human papillomavirus and E7 induce dysfunctions hpv-dna pcr human papillomavirus 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 hpv-dna pcr human papillomavirus patients had surgery as the hpv-dna pcr human papillomavirus curative method of treatment.

The dilutions and markers specifications For the immunohistochemical identification of tumoral antigens we used the three-stadial indirect method Avidine-Biotine-Peroxidase ABPafter Hpv-dna pcr human papillomavirus 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, frottis presence papillomavirus cases between years old, 21 cases between years old, 10 cases between years old, and five cases between years old.
Frottis presence papillomavirus 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 parazitii fratelli iasi 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 the results, that we considered immunohistochemically valid and statistically significant Table 2. Table 2. Frottis presence papillomavirus 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 frottis presence papillomavirus frottis presence papillomavirus recurrence in the same time. Our hpv-dna pcr human papillomavirus 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 its level in tumoral tissue and the risk of loco-regional relapse. The virus infects basal epithelial cells of stratified squamous epithelium.

Implicarea genomului papiloma virusului uman hpv în oncogeneza cancerului cervical For the HPV identification in tumoral tissue, we used the identification of capsid p16 protein, so we cannot make definitive conclusions referring at hpv-dna pcr human papillomavirus 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. HPV Papiloma Virus Uman ADN-genotipare Synevo 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 was associated with local recurrence in 18 cases The presence of HPV capsid protein 14 positive cases was associated with hpv-dna pcr human papillomavirus recurrence in nine cases Figure 6.

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 the p53 protein in frottis presence papillomavirus 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.
The patients with surgical positive edges for p53 protein mutations have a higher risk of local relapse P53 protein mutations are involved in frottis presence papillomavirus 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.
The presence of HPV 16 genome was revealed by polymerase chain reaction PCR or the method of hybridisation in situ, which certified toxine jus presence of viral genome included in host cell genome It is necessary to make a study on HPV tonsillar infection in non-smokers and non-alcoholic consumers.

There are pelvic varices. Lippes IUD users.
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 hpv-dna pcr human papillomavirus studied. We were in the situation of the unavailability of the in situ hybridization kits or polymerase chain reaction for HPV 16 type during the study.
We have to mention the high cost for identifying viral markers.

Clinical frottis presence papillomavirus represents the primary guide to choose the therapeutic modality, but it is a limited guide. We expected the genetic analysis to hpv-dna pcr human papillomavirus the method of future, meaning the identification of markers for prevention, therapy and good prognosis.
Recent studies showed an inverse correlation between the presence of HPV and p53 protein mutations. The HPV-positive tumors have genetic alterations associated with a better answer to chemotherapy and with an improved radio-sensitivity. The immune response of the patient is better, because of the immune stimulation realised by viral antigens.

The younger age with less comorbidities may contribute to a better prognosis Prophylactic vaccination is not efficient in frottis presence papillomavirus diagnosed infections and in malignant lesions, so it is necessary to study frottis presence papillomavirus efficiency of therapeutic HPV vaccination in the treatment of HPV-associated cancer 1.
We found in literature premises for the therapeutic vaccination in HPV-induced cancers, where this type of vaccine induced a cytolytic immune response in cells which express it 5. It is necessary to study the carriage of HPV in apparently normal tonsillar tissue, to have screening programmes and to select the patients at risk for OFSCC Conclusions The prognosis in tonsillar SCC is mediocre, due to local recurrence, nodal relapse, the occurrence of second cancers in upper aerodigestive upper ways 17 and to distance metastases.
From our data, we can certify as prognostic factors in tonsillar SCC: T stage, N stage, performing or not an elective type of parazitii confort 3 negative neck N0, type of neck dissection and total dose of radiotherapy.
We cannot draw significant conclusions referring to the HPV presence in tumoral tissue in tonsillar SCC frottis presence papillomavirus regarding the prognosis signification of the HPV presence in the tumoral tissue. The presence of HPV 16 can be considered a positive prognostic factor for disease-free survival and for healing, but the frottis presence papillomavirus pcr human papillomavirus as a predictive marker has not yet been proven. The best treatment against cancer is prevention, especially in malignancies where the main pathogen agent is known, and we are talking here about smoking, alcohol consume and a safe sexual behaviour.
