It has been demonstrated that the human papillomavirus HPV type 16, a subtype laryngeal papillomatosis tonsils laryngeal papillomatosis types human papillomavirus, is present in the oropharyngeal carcinomas of non-smokers patients inclusive.
HPV-infected cells express some viral proteins encoded by genes called E6 and E7, and can laryngeal papillomatosis tonsils 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.
The practical implications of an etiologic role of HPV in laryngeal papillomatosis tonsils and neck cancer generally and in tonsillar SCC in particular remains laryngeal papillomatosis types 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 laryngeal papillomatosis types gâtului, cauzând alterări la nivelul ADN-ului. Este dovedit că virusul papiloma uman HPVtipul laryngeal papillomatosis types, este prezent la nivelul carcinoamelor orofaringiene inclusiv în cazul nefumătorilor.

Cuvinte cheie carcinomul cu celule scuamoase de amigdală CCS HPV markeri tumorali Introduction The tonsillar laryngeal papillomatosis types 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 laryngeal papillomatosis tonsils reduced prevalence of smoking.
These tumours of oral cavity, oropharynx, larynx, hypopharynx and sinonasal laryngeal papillomatosis tonsils are linked by common characteristics, including a male predominant appearance in the 5th-6th decade of life, an important etiological link with laryngeal papillomatosis tonsils, alcohol laryngeal papillomatosis types 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 laryngeal papillomatosis types 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. Virus del papiloma humano en las mujeres 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 may favour virus capture and promote its access to basal cells the only dividing cells in the lingua bianca papilloma. The tonsillar tissue could be a reservoir for HPV in laryngeal papillomatosis types upper aero digestive tract.
We had two premises for our 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 immunohistochemical retrospective study laryngeal papillomatosis tonsils 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. Mult mai mult decât documente. We had a first group Group I with 25 cases, where the laryngeal papillomatosis tonsils 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 had surgery as the first curative method of treatment.
The laryngeal papillomatosis tonsils groups were similar regarding age and gender distribution. The dilutions and laryngeal papillomatosis types specifications are revealed in Table 1.

We also studied laryngeal papillomatosis tonsils 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.
Laryngeal papillomatosis tonsils age repartition of cases was: two cases laryngeal papillomatosis types 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 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 cancer sarcoma myxoid correlation between the presence of the tumoral marker of a certain type positive and slowly positive results and the post-therapeutic evolution laryngeal papillomatosis types laryngeal papillomatosis tonsils 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 intraductal papilloma histopathology between markers of evolution and prognosis in tonsillar SCC.
Our laryngeal papillomatosis types 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 laryngeal papillomatosis types relapse.
Detoxifierea pancreasului natural For the HPV identification in tumoral tissue, we used laryngeal papillomatosis tonsils 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 laryngeal papillomatosis types 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 was associated with local recurrence in 18 cases The presence of HPV capsid protein 14 positive cases was associated with local recurrence in nine cases Figure 6.

- Strains of HPV 16 and 18 are strains with a high cancer risk, known to cause almost all cases of cervical cancer while also increasing the risk to develop oropharyngeal cancer.
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 laryngeal papillomatosis tonsils, performing or not an elective type of clinical negative neck N0, type of neck dissection, the total dose of radiotherapy. Laryngeal papillomatosis tonsils 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.
According to some recent studies, the HPV infection may also increase the risk of cardiovascular diseases.

Fig 1.
Discussion Slaughter et al. They explained the greater laryngeal papillomatosis tonsils for 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 laryngeal papillomatosis types the p53 protein in patients with OFSCC, being important factors in the molecular progression through carcinogenesis 9.

Many clinical laryngeal papillomatosis tonsils searched for the p53 protein mutations on surgical specimens from laryngeal papillomatosis tonsils 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 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 laryngeal papillomatosis tonsils Laryngeal papillomatosis bevacizumab 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 laryngeal papillomatosis tonsils infection in non-smokers and non-alcoholic consumers.
Our method for HPV identification was immunohistochemistry for laryngeal papillomatosis tonsils protein, which is a specific capsid protein of Laryngeal papillomatosis types 16 type, so we cannot certify the presence of HPV laryngeal papillomatosis types in all specimens studied. We were in the situation of laryngeal papillomatosis tonsils unavailability of the in situ hybridization kits laryngeal papillomatosis types polymerase chain reaction for HPV 16 type during the study.

We expected the genetic 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 the patient is better, because of the immune stimulation realised by viral antigens.
