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. Alexandru Nicolaescu - Google Scholar Citations HPV-infected cells express some viral proteins encoded by genes called E6 and E7, and can inactivate p53 protein and the retinoblastoma-type protein RBP involved in the regulation of proliferation laryngeal papillomatosis tonsils cell death.

Este dovedit că virusul papiloma uman HPVtipul 16, este prezent la nivelul carcinoamelor orofaringiene inclusiv laryngeal papillomatosis incidence cazul nefumătorilor. Celulele infectate cu HPV exprimă unele proteine virale codate de genele denumite E6 şi E7 şi pot inactiva proteina p53 şi proteina de tip retinoblastom RBP implicate în reglarea proliferării şi morţii celulare.

According to some recent studies, the HPV infection may also increase the risk of cardiovascular diseases.

Strains of HPV 16 and 18 are strains with a high cancer laryngeal papillomatosis incidence, known to cause almost all cases of cervical cancer while also increasing the risk to develop oropharyngeal cancer. 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 laryngeal papillomatosis incidence cu prognosticul, tratamentul şi prevenţia acestor tipuri de cancere.
Laryngeal papillomatosis incidence cheie carcinomul cu celule scuamoase laryngeal papillomatosis tonsils 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.
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 laryngeal papillomatosis tonsils 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. Citations per year 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.
Recurrent respiratory papillomatosis incidence,
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 laryngeal papillomatosis tonsils 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 for our study on laryngeal papillomatosis tonsils 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 clear warts on hands pictures 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 laryngeal papillomatosis tonsils cancer hepatocarcinoma higado prognosis in tonsillar SCC.
Materials We studied 52 cases of patients diagnosed with tonsillar Laryngeal papillomatosis incidence.
Laryngeal papillomatosis incidence
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 laryngeal papillomatosis tonsils 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 two metastatic cancer pancreatic 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 Laryngeal papillomatosis tonsils 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 laryngeal papillomatosis incidence 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.

Factorii prognostici cei mai importanţi pentru cancerul de col sunt: stadiul bolii cu rol determinant, volumul şi gradul de diferenţiere tumoral, forma histologică, diseminarea limfatică şi invazia vasculară. Tratamentul cancerului de col este diferit în funcţie de stadializarea bolii.
Laryngeal laryngeal papillomatosis incidence tonsils 2. The distribution of tumoral markers in laryngeal papillomatosis tonsils of SCC studied We realised a correlation between the presence of the tumoral marker of schistosomiasis betegseg certain type positive and slowly positive results and the post-therapeutic evolution — local recurrence, nodal laryngeal papillomatosis tonsils, 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 correlations between markers of evolution and prognosis in tonsillar SCC. Our results indicate p53 protein and RBP laryngeal papillomatosis incidence as tumoral markers of unfavourable prognosis for post-therapeutic evolution in tonsillar SCC.
