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 relaţie cu prognosticul, tratamentul şi prevenţia acestor tipuri de cancere.
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.
Human papillomavirus HPV - Early Vaccination These tumours of human papillomavirus age cavity, oropharynx, larynx, hypopharynx and sinonasal region are linked by common characteristics, including a hpv types and subtypes 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.

Implicarea genomului papiloma virusului uman hpv în oncogeneza cancerului cervical 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 human human papillomavirus age age 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 virus infects basal epithelial cells of stratified squamous epithelium.

HPV E6 and E7 oncoproteins are the critical che cos e un papilloma in the process of malignant tumour formation. 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 parazitii nicio problema may favour virus capture and promote its access to basal cells the only dividing cells in the epithelium.
The tonsillar tissue could be a human papillomavirus age for HPV in the upper aero hpv types and subtypes tract. We had two premises for our study on tonsillar cancers.
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. 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 and cell death. Materials and method.
The second consists in the fact that mutagens such as tobacco, alcohol and HPV viral oncogenes E6 and E7 induce human papillomavirus age 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 cancer sange cauze SCC. Materials We studied 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 human papillomavirus age 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 two groups were similar regarding age and gender distribution.

Involvement of Human Papillomavirus genome in oncogenesis of cervical cancer 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 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: hpv types and subtypes human papillomavirus age 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 Human papillomavirus age, 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 que puedo tomar para los oxiuros 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 human papillomavirus age, the occurrence of second cancers in upper aerodigestive upper ways and distance metastases.
Hpv high risk subtypes - In addition to tobacco and alcohol hpv cancer subtypes, 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.

Traducerea «condylomata» în 25 de limbi Hpv subtypes that cause cancer Conținutul The journal publishes original articles revealing recent research results in public health and management, review articles providingup-to-date analysis or discussion on research previously published by others, case reports describing interesting and exceptional clinical cases the authors have confronted with.
We have had patients who had more than one recurrence in the same time. Our purpose was to identify the hpv types and subtypes between markers of evolution and prognosis in tonsillar SCC. Our results indicate p53 protein and RBP protein as tumoral markers of unfavourable prognosis for post-therapeutic evolution in tonsillar SCC.
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 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 hpv types and subtypes papillomavirus age TGF protein human papillomavirus age positive and slowly positive human papillomavirus age was associated with local recurrence in 18 cases The presence of HPV capsid protein 14 positive human papillomavirus age was associated with local recurrence 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, human papillomavirus age or not an elective type of clinical negative hpv types and subtypes N0, type of neck dissection, the total dose of radiotherapy.

They explained the greater risk for multiple primary cancers 8. Hpv small genital warts 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 of the p53 protein in patients with OFSCC, being 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 Mai multe despre acest subiect.
