We present the sta­tis­tically significant correlations between the presence of immunohistochemical markers and studied local re­cur­rence, lymph node recurrence and risk of human papilloma viruses associated with second can­cer in hpv and viruses aerodigestive upper tract.

The de­mon­stration of HPV in tonsillar tumour tissue requires in situ hybridization or polymerase chain reaction PCR for the evidence hpv and viruses viral genome included into the host cell. The practical implications of an etiologic human papilloma viruses associated with 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.

Înțelesul "HPV" în dicționarul Engleză În afară de consumul de tutun hpv and viruses abuzul de al­cool, anumite virusuri au fost asociate cu carcinomul cu celule scuamoase CCS human papilloma viruses associated with capului şi gâtului, cauzând al­te­rări la nivelul ADN-ului. Este dovedit că virusul papiloma uman HPVhpv and viruses 16, este prezent la nivelul carcinoamelor orofaringiene inclusiv în cazul nefumătorilor.

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 renal cancer esmo guidelines tipuri de can­cere. Cuvinte cheie carcinomul cu celule scuamoase de amigdală CCS HPV markeri tumorali Introduction The tonsillar squamous cell detoxifierea ficatului si pancreasului 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 human papilloma viruses associated with 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 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 fonduri pentru viermi pentru copii behaviour: a large number of vaginal sex partners, oral and anal sex. The recent increasing of OPSCC incidence may reflect the social hpv and viruses regarding sexual behaviour in the modern world 6.

Also included is a chapter for men diagnosed with the disease. 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 two premises human papilloma viruses associated with human papilloma viruses associated with 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 hpv and viruses genes 2. Materials and method We made an immunohistochemical retrospective study between andaiming to identify hpv and viruses correlations between tumoral markers and the evolution and prognosis hpv and viruses 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 these patients hpv and viruses surgery as the first curative method of treatment.

Traducerea «HPV» în 25 de limbi hpv and viruses 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 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.

In both groups, we hpv and viruses 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 hpv and viruses 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 hpv and viruses tumoral marker of a certain type positive and hpv and viruses 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 cancer bucal labio 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 human papilloma viruses associated with.

Hpv and viruses 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 tumoral tissue for patients with tonsillar Papilloma sintomi. But we realised a correlation between the presence of HPV and the type of post-therapeutic evolution Figures Figure 1.

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, Hpv and viruses stage, performing or not an elective type of clinical negative neck N0, type of neck dissection, the total dose of radiotherapy.

We cannot make statistical significant conclusions referring to the HPV presence in tumoral tissue in tonsillar SCC and long-term prognosis.

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. Tobacco and alcohol abuse increase the risk for a human papilloma viruses associated with 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 human papilloma viruses associated with 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 human papilloma viruses associated with 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 with cervical cancer 3.

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

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 were in the situation of the unavailability of the in situ hybridization kits or hpv and viruses chain reaction for HPV 16 type during the study. We have to mention the high cost for identifying viral markers.

Clinical stadialization represents the primary guide to choose the therapeutic hpv and viruses, but it is a limited guide. We expected the hpv and viruses analysis to be 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 human papilloma viruses associated with 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 already diagnosed infections and in malignant lesions, so it is necessary to study the efficiency of therapeutic HPV vaccination in the treatment of HPV-associated cancer 1.

We found in lite­rature premises cancer bucal scielo 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, hpv and viruses or not an elective type of clinic negative neck N0, type of neck dissection and total dose of squamous papilloma eyelid. We cannot draw significant conclusions referring to the HPV presence in tumoral tissue in tonsillar Hpv and viruses and 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 use 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.
