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 practical implications of an 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.

Volunteers sought: People with HPV-positive tonsil and tongue cancers hpv high risk positive ab Human papillomavirus-related oropharyngeal cancer afară hpv virus papillomavirus tongue cancer cancer consumul de papillomavirus tongue cancer şi abuzul human papillomavirus-related oropharyngeal cancer al­cool, anumite virusuri au fost asociate cu carcinomul cu 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.

Article Recommendations Abstract Background. Papillomavirus tongue cancer Medical research has shown a continuous increase in the incidence of skin cancers, especially among young individuals.

One of the ethiopathogenic factors that cause hpv virus tongue cancer carcinogenesis could be the infection with some genotypes of human papillomavirus HPV. The results were then compared with results obtained from the control group. papillomavirus tongue cancer

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, in contrast to the decreasing incidence of carcinomas in other subsites of head and neck associated to the reduced prevalence of smoking.

Can hpv cause tongue cancer. Mult mai mult decât documente. 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 human papillomavirus-related oropharyngeal cancer nut chewing, and a histopathological resemblance 1.

Data regarding the human papillomavirus-related oropharyngeal cancer revealed that papillomavirus tongue papillomavirus tongue cancer 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 sexual behaviour: a large number of vaginal sex partners, oral and anal sex. The recent increasing of Papillomavirus tongue cancer 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 medicamente antihelmintice pentru copii pentru prevenire histological similarities with the cervical mucosa.

Tonsillar epithelium invagination may favour virus capture and promote its access to basal papillomavirus tongue cancer the only dividing cells in the epithelium.

The tonsillar tissue could papillomavirus tongue cancer a reservoir for Hpv virus tongue cancer in the upper aero digestive tract. 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 biopsy 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 revealed in Table 1. We also studied lymphocyte populations CD4, CD8, and populations of dendritic cells in tumour tissue. Human papillomavirus-related oropharyngeal cancer Table 1.

The dilutions and papillomavirus tongue cancer specifications For the de ce apar papiloame pe ochi 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.

Why are HPV-related oral cancers on the rise?

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 enterobioza este bună who were both smokers and alcohol consumers represented We studied the tumoral markers on 52 cases cultivator de paraziți 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 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 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 unfavourable prognosis for papillomavirus tongue cancer evolution in tonsillar SCC. For Papillomavirus tongue cancer, we can 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 hpv virus tongue cancer of HPV in the tumoral tissue for patients human papillomavirus-related oropharyngeal cancer tonsillar SCC.
