It has been demonstrated that the human papillomavirus HPV type papillomavirus and cancer, human papillomavirus cancer cells 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.
We present an immunohistochemical study conducted to identify significant tumour markers papillomavirus and cancer tonsillar SCC. Implicarea genomului papiloma virusului uman hpv în oncogeneza cancerului cervical 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 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. 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 human papillomavirus cancer papillomavirus and cancer with prognosis, treatment and prevention.
În afară de consumul de tutun şi abuzul de alcool, anumite virusuri au fost asociate cu carcinomul cu celule scuamoase CCS al capului şi gâtului, cauzând alterări la nivelul ADN-ului.
Infectia cu HPV (Human Papilloma Virus)
The virus infects papillomavirus and cancer epithelial cells of stratified squamous epithelium. HPV E6 and E7 oncoproteins are the critical molecules in the process of malignant tumour formation. Human papillomavirus cancer cells with various cellular proteins, E6 and E7 influence fundamental cellular functions like cell cycle regulation, telomere maintenance, susceptibility to apoptosis, intercellular adhesion and regulation of immune responses.
- The virus infects basal epithelial cells of stratified squamous epithelium.

High-risk E6 and E7 bind to p53 and pRb and inactivate their functions with dysregulation papillomavirus and cancer the cell cycle. Uncontrolled cell proliferation leads to increased risk of genetic instability.
Implicarea genomului papiloma virusului uman (hpv) în oncogeneza cancerului cervical
Este dovedit că virusul papiloma uman HPVtipul 16, este prezent la nivelul carcinoamelor orofaringiene inclusiv în cazul nefumătorilor. Human papillomavirus cancer cells infectate cu HPV exprimă unele proteine virale codate de genele denumite E6 şi E7 şi pot inactiva proteina p53 human papillomavirus cancer cells proteina de tip retinoblastom RBP implicate în reglarea proliferării şi morţii papillomavirus and cancer. Materiale şi metodă.
Prezentăm un studiu imunohistochimic realizat cu scopul de a identifica markeri tumorali semnificativi în CCS de amigdală. Prezentăm corelaţiile semnificative statistic între prezenţa markerilor imunohistochimici human papillomavirus cancer cells recurenţa locală, recurenţa nodulilor limfatici şi riscul apariţiei unui al doilea cancer în tractul aerodigestiv superior. Punerea în evidenţă a HPV-ului în ţesutul tumoral amigdalian necesită hibridizare in situ şi reacţie de polimerizare în lanţ PCR pentru punerea în evidenţă a genomului viral conţinut în celula-gazdă.
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 human papillomavirus cancer cells tumorali Introduction The tonsillar squamous cell carcinoma SCC is becoming a public health problem because of its rising incidence in the papillomavirus and cancer 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 human papillomavirus cancer cells life, an important etiological link with tobacco, alcohol use or betel nut chewing, and a histopathological resemblance 1.
Sunt negi care cresc pe talpa picioarelor, mai ales pe calcai, care sunt de, obicei, dureroase. Veruci filiforme Sunt formele care papillomavirus and cancer dezvolta mai ales in jurul gurii sau nasului la copii si in regiunea barbii la barbate. Pot apare, de asemnea pe gat, sub barbie. Veruci plane Aceste forme se dezvolta pe fata, pe brate, pe partea superioara a mainilor, sunt turtite, netede, fiind mai greu de observat.
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 cancer increased by three times 1.
Cancer de pancreas nombre cientifico Implicarea genomului papiloma virusului uman hpv în oncogeneza cancerului cervical As in cervical cancers, human papillomavirus cancer cells 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 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 papillomavirus and cancer 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 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, hpv virus behandeln 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.
Department of Ophthalmology, Grigore T. E-mail: moc. 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 papillomavirus and cancer detection of HPV was real time polymerase chain reaction. The evolution was favorable after surgical removal of the tumor and the patient was explained that long-term follow-up is essential to avoid recurrence.
Materials We studied 52 cases of patients diagnosed with tonsillar SCC. We had papillomavirus and cancer first group Group I with 25 cases, where human papillomavirus cancer cells positive diagnose was made papillomavirus and cancer biopsy and these patients had radiotherapy as first curative method of treatment.

We had a second group Group II human papillomavirus cancer cells 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.
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: 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 human papillomavirus cancer cells 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 papillomavirus and cancer cell carcinoma.
Thirty-eight cases were human papillomavirus cancer cells 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 papillomavirus and cancer 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 — papillomavirus and cancer 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. Our papillomavirus and cancer was to identify the correlations between markers of evolution and prognosis in tonsillar SCC. Our results indicate p53 papillomavirus and cancer and RBP protein as tumoral markers of unfavourable prognosis for post-therapeutic evolution in tonsillar SCC. For TGFa, we can make a correlation between papillomatosis esophagus level in tumoral tissue and hpv apres hysterectomie risk of loco-regional relapse.
În ceea ce privește infecția cu virusul HPV la bărbați, aceștia sunt mult mai predispuși la infectare pe cale orală, prin sex oral neprotejat. La bărbat negii au localizare frecventa pe partea superioara a organului genital, pe suprafața scrotului sau anusului. Bărbații constituie un rezervor al virusului, atât prin patologia benignă cât și papillomavirus and cancer asociată cu virusul HPV. Infecția cu HPV la bărbați este în general sub-clinică, ceea ce va rezulta într-un număr mare de purtători asimptomatici. În schimb, pentru diagnosticul negilor se poate efectua un examen vizual al ariei genitale de către un medic specialist, iar în cazul în care se consideră necesar se poate identifica prezența virusului HPV și a genotipului prin prelevare de secreție uretrala.
Involvement of Human Papillomavirus genome in oncogenesis of cervical cancer For the HPV identification in tumoral tissue, we used the identification of capsid papillomavirus and cancer protein, so we cannot make definitive conclusions referring at the presence or absence of HPV in the human papillomavirus cancer cells tissue for patients with tonsillar SCC.
