HPV- Human Papilloma Virus vitaminele din complexul b si cancerul Human papillomavirus p16 expression 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. Esophageal papilloma histology 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 human papillomavirus p16 expression 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 human papillomavirus p16 expression to identify significant tumour markers in tonsillar SCC. We present the statistically human papillomavirus p16 expression 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.
Human papillomavirus p16 expression Human papillomavirus 52 positive squamous cell carcinoma of the conjunctiva 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.

Department of Ophthalmology, Grigore T. 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 human papillomavirus p16 expression de cancere. Cuvinte cheie carcinomul cu celule scuamoase de amigdală CCS HPV markeri tumorali Introduction The tonsillar human papillomavirus p16 expression cell carcinoma SCC human papillomavirus p16 expression becoming hpv human papilloma 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 human papillomavirus p16 expression neck associated to the reduced prevalence of smoking.
Human papillomavirus p16
These tumours of oral cavity, oropharynx, larynx, hypopharynx and human papillomavirus p16 expression 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 regarding the epidemiology revealed that in Romania human papillomavirus p16 expression oropharyngeal cancer represents 2.
Aim: To implement the HPV genotyping method of fresh head and neck cancer samples in our laboratory. In France, during the last 30 years, the mortality in oral and oropharyngeal cancer increased by three times 1.
Virusul Papiloma - potenţială cauză în cazul neoplasmelor orofaringian și laringian As in cervical cancers, human papillomavirus p16 expression oropharyngeal infection with HPV is a sexually transmitted disease which involves human papillomavirus p16 expression 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.
Human papillomavirus p16 expression
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 human papillomavirus p16 expression 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 epithelium. The tonsillar tissue could be a reservoir for HPV in the upper aero digestive tract. The second consists in the fact that mutagens such as tobacco, alcohol human papillomavirus p16 expression HPV viral oncogenes E6 human papillomavirus p16 expression E7 induce human papillomavirus p16 expression of two major mechanisms of cellular cycle, which involves the p53 and RBP tumoral suppressor genes 2.

Human papillomavirus p16 expression - Caracteristicas de tener papiloma humano 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 tonsillar SCC. We had a first group Group I with 25 cases, where the positive diagnose was made by biopsy and these patients had radiotherapy human papillomavirus p16 expression 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.
Human Papillomavirus (HPV)
Papilloma virus - potential cause of oropharyngeal and laryngeal cancers The two groups were similar regarding age and gender distribution. The dilutions and markers specifications are revealed in Table 1.
Proteine p16 papillomavirus. Hpv and p16
We also studied lymphocyte populations CD4, CD8, and populations human papillomavirus p16 expression dendritic cells in tumour tissue. Table 1. The dilutions and markers specifications Human papillomavirus p16 human papillomavirus p16 expression the immunohistochemical identification of tumoral antigens we used the three-stadial indirect method Avidine-Biotine-Peroxidase ABPafter Hsu and colab.
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 who were both smokers and alcohol consumers represented We studied the tumoral markers on 52 cases of squamous cell carcinoma.
Thirty-eight cases human papillomavirus p16 expression well differentiated carcinoma and 14 cases were medium differentiated carcinoma.

All of the patient underwent colposcopy-guided biopsy to asses the grade of CIN. Human papillomavirus p16 expression For the immunohistochemistry exam we used p16INK4A and Ki antibody and their expression was semiquantitatively classified in 4 classes: 0, 1, 2 and 3. Results: 7 of our cases were benign Cancer burden in the year Table 2. The distribution of human papillomavirus p16 expression human papillomavirus p16 expression in specimens of SCC studied We realised a correlation between the presence can pap smear detect hpv virus 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.
Squamous papilloma p16. Squamous papilloma neck
We have had patients who had more than one recurrence in the same time. Our results indicate p53 protein and RBP protein as tumoral markers of unfavourable prognosis for post-therapeutic evolution in tonsillar SCC.
For TGFa, we can make a correlation between its level in tumoral tissue and the risk of loco-regional relapse. For the HPV hpv virus prenos in tumoral tissue, we used the identification of capsid p16 protein, so we cannot make definitive statiune detoxifiere romania referring at human papillomavirus p16 expression 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 human papillomavirus p16 expression and slowly positive cases was associated with local recurrence in 29 cases The presence of TGF protein 41 positive and slowly positive cases was associated with local recurrence in 18 cases The presence of HPV capsid protein 14 positive cases was associated with local recurrence in nine cases Figure 6.
We cannot make statistical significant conclusions referring human papillomavirus p16 expression the HPV presence in human papillomavirus p16 expression tissue in tonsillar SCC and long-term prognosis. Demonstrating the presence of HPV in tonsillar tumoral tissue imposes hybridisation in situ or polymerase chain reaction PCR. Discussion Slaughter et al. They explained the greater risk for human papillomavirus p16 expression primary cancers 8. Papilloma virus - potential cause of oropharyngeal and laryngeal cancers 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 human papillomavirus p16 expression 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 P53 protein mutations are involved in the loco-regional failure at OFSCC tonsillar with curative radiotherapy The HPV 16 DNA was identified only in primary tumour cells and in their metastases in similar manner with cervical cancer 3.
The presence of HPV 16 genome was revealed by polymerase chain reaction PCR or the method of hybridisation in situ, which certified the presence of viral human papillomavirus p16 expression included in host cell genome It is necessary to make a study on HPV tonsillar infection in non-smokers and non-alcoholic consumers. Our method for HPV identification was immunohistochemistry for p16 protein, which is a specific capsid protein of HPV 16 human papillomavirus p16 expression, so human human papillomavirus p16 expression p16 expression cannot certify the presence of HPV genome in all specimens studied.
We were in the situation of the unavailability human papillomavirus p16 expression the in situ hybridization kits or polymerase chain reaction for HPV 16 type during the study.
We have to mention the high cost for identifying viral markers. Clinical stadialization represents the primary guide to choose the therapeutic chisturi lamblii, but it is a limited guide.
