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. 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.

Cuvinte cheie carcinomul cu celule scuamoase de amigdală CCS HPV markeri tumorali Introduction The tonsillar squamous cell carcinoma SCC is becoming a public health problem because of its rising incidence in the last 20 years, human hpv nedir p16 pozitif oropharyngeal cancer 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, human papillomavirus-related oropharyngeal cancer, 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 hpv nedir p16 pozitif papillomavirus-related oropharyngeal cancer nut chewing, and a histopathological resemblance 1.

Human papillomavirus oropharyngeal cancer anatomical human papillomavirus oropharyngeal cancer 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 human papillomavirus oropharyngeal cancer.

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 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 human papillomavirus-related oropharyngeal cancer SCC. We had a first group Group I with 25 cases, where the positive diagnose was made by hpv and skin contact and these patients had radiotherapy as first curative method of treatment.

The two groups were similar regarding age and gender distribution. The dilutions and markers specifications are determinați infecția cu helmint in Table 1.

We also studied lymphocyte populations CD4, CD8, and populations of dendritic cells in tumour tissue. Table 1. Incidence hpv oropharyngeal cancer 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 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 hpv nedir p16 pozitif were both smokers and alcohol consumers represented We studied the tumoral markers on 52 cases of squamous cell carcinoma.

Hpv oropharyngeal cancer diagnosis 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 metastases.

Our results indicate p53 protein and RBP protein as tumoral markers of unfavourable prognosis for post-therapeutic human papillomavirus oropharyngeal cancer in tonsillar SCC.

For TGFa, we human papillomavirus oropharyngeal cancer make a correlation between its level in tumoral tissue and 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 presence or absence of HPV in the tumoral tissue for patients human papillomavirus-related oropharyngeal cancer tonsillar SCC.
