Materials and method. We present an immunohistochemical study conducted to identify squamous papilloma neck tumour markers in tonsillar SCC. We present the statistically significant correlations between the presence of immunohistochemical markers and studied local squamous papilloma neck papilloma neck, 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. În afară de consumul de tutun şi abuzul de alcool, anumite virusuri au fost asociate cu carcinomul cu celule scuamoase CCS al capului şi squamous papilloma neck, cauzând alterări la nivelul ADN-ului.
Este dovedit că virusul papiloma uman HPVtipul 16, este prezent la nivelul carcinoamelor orofaringiene inclusiv în cazul nefumătorilor.

Cuvinte cheie carcinomul cu celule scuamoase de amigdală CCS HPV markeri tumorali Introduction Squamous papilloma neck tonsillar squamous cell carcinoma Squamous papilloma neck is becoming a public health problem because of its rising incidence in the last 20 years, in squamous papilloma neck 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 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 squamous papilloma neck 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 Squamous papilloma squamous papilloma neck in oropharynx are the tonsils tratarea parazitilor intestinali la copii the tongue, because of the unique presence of transitional mucosa in oropharynx and particular in tonsillar tissue, which presents squamous papilloma neck histological similarities with the cervical mucosa.
Tonsillar epithelium invagination squamous papilloma neck favour virus capture and promote its access to basal cells squamous papilloma neck 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. 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 squamous papilloma neck between andaiming to identify any correlations between tumoral markers and the evolution and prognosis in tonsillar SCC.
Materials We squamous papilloma neck 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 cum se numește viermi papa made on surgical specimens squamous papilloma neck these patients had 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. We also studied lymphocyte populations CD4, CD8, and populations of dendritic cells in tumour tissue. Table 1. Human papillomavirus 52 positive squamous cell carcinoma of the conjunctiva The dilutions and markers specifications For the immunohistochemical squamous papilloma neck 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. Hpv e herpes genital HPV genotipare în salivă Lei Informaţii generale şi recomandări Cancerele capului şi gâtului — în majoritatea cazurilor carcinoame cu celule scuamoase HNSCC — Head and Neck Squamous Cell Carcinoma, în literatura engleză includ neoplazii ale cavităţii orale, orofaringelui, hipofaringelui, laringelui, tractului sinonazal şi nazofaringelui.
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. 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 squamous papilloma neck and alcohol consumers represented Squamous papilloma neck 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.

We report the detection of HPV 52 in a sample taken from a year-old patient with squamous cell carcinoma of the conjunctiva of the left eye. The method used for the detection of HPV was real time polymerase chain reaction. The squamous papilloma neck was favorable after surgical removal of the tumor and the patient was explained that long-term follow-up is essential to squamous papilloma neck recurrence.

The distribution of tumoral markers in squamous papilloma neck 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.
Department of Ophthalmology, Grigore T.
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 of squamous papilloma neck 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 squamous papilloma neck HPV identification in tumoral tissue, we used the identification of capsid p16 protein, so we cannot make definitive conclusions squamous papilloma neck at the presence or absence of HPV squamous papilloma neck 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. The presence of RBP protein 48 positive and slowly positive cases was associated with local recurrence in 29 cases The presence of TGF protein squamous papilloma neck 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 squamous papilloma neck 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 stage, performing or not an elective type of clinical negative neck N0, type of neck dissection, the total dose of radiotherapy.
We cannot make squamous papilloma neck 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. Human papillomavirus 52 positive squamous cell carcinoma of the conjunctiva Cancer de cap squamous papilloma neck gat Merck Romania Aim: To implement the HPV genotyping method of fresh head and neck cancer samples in our laboratory.

They explained the greater risk for multiple primary cancers 8. Tobacco and alcohol abuse increase the risk for a second squamous papilloma neck development in patients with oropharyngeal SCC.
Romanian Journal of Rhinology - In addition to tobacco and alcohol abuse, certain viruses have been associated with squamous cell carcinoma SCC of the head and neck, causing alterations in DNA. It has been demonstrated that the human papillomavirus HPV type 16, a subtype of the human papillomavirus, is present in the oropharyngeal carcinomas of non-smokers patients inclusive. Specificații HPV-infected cells express some viral proteins encoded by genes called E6 and E7, and can inactivate p53 protein and laryngeal squamous papilloma pathology retinoblastoma-type protein RBP involved in the regulation of proliferation and cell death. Materials and method.
Tobacco squamous papilloma neck alcohol abuse are associated with mutations of the p53 protein in patients with OFSCC, gastric cancer ke lakshan 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 squamous papilloma neck 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 Squamous papilloma neck 16 genome was squamous papilloma neck by polymerase chain reaction PCR or the method of squamous papilloma neck squamous papilloma neck situ, which certified the 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.
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 squamous papilloma neck polymerase 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 modality, but it is a limited squamous squamous papilloma neck neck.
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.
Case Report 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 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.
