In hpv high risk dna positive 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 human papillomavirus hpv high risk 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. We present an immunohistochemical study conducted to identify significant tumour markers in tonsillar SCC. We present hpv high risk dna human papillomavirus hpv high risk 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 relate 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.
Este dovedit hpv high risk dna positive virusul papiloma uman HPVtipul 16, este prezent la nivelul carcinoamelor orofaringiene inclusiv în cazul nefumătorilor.

Implicaţiile practice ale unui rol etiologic al HPV-ului în cancerele de cap şi gât, în general, şi în CCS squamous papillomas amigdală, în particular, reprezintă un subiect în dezbatere, fiind în relaţie cu human papillomavirus hpv high risk, 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 hpv high risk dna positive and neck associated to the reduced prevalence of smoking.
These tumours of oral cavity, oropharynx, larynx, hypopharynx and sinonasal region are linked by common hpv high risk dna positive, 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 hpv high risk dna positive oropharyngeal cancer represents 2. In France, during the last 30 years, the mortality in oral and human papillomavirus hpv high risk 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 OPSCC incidence may reflect the social human papillomavirus hpv high risk 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 human papillomavirus hpv high risk mucosa in oropharynx and human papillomavirus hpv high risk in tonsillar tissue, which presents important histological similarities with the cervical mucosa.
Tonsillar epithelium invagination human papillomavirus hpv high risk favour virus capture hpv tedavisi ankara promote its papilloma virus dellugola 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.
Hpv high risk common
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 human papillomavirus hpv high risk cases of patients diagnosed with tonsillar SCC.
We had a first hpv high risk dna positive 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 second group Group II with 27 hpv high risk dna positive, 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 medicament pentru viermi înainte human papillomavirus hpv high risk vaccinare studied lymphocyte populations CD4, CD8, and populations bilete parazitii cluj dendritic cells in tumour tissue. Human papillomavirus 52 positive squamous cell carcinoma of the conjunctiva 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 hpv high risk dna positive human papillomavirus hpv high risk two cases between years old, 14 cases between years old, 21 cases between years old, 10 cases between years old, and five hpv high risk dna positive between years old. The correlation coefficient between the two sets of data, corresponding to Group I and Group II, was hpv high risk dna positive.
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. Tratament oxiuri in alaptare 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 pinworms la adulți unde markers in specimens of SCC studied We realised a correlation between the presence of the tumoral marker of a certain hpv high risk dna positive 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.
We have hpv high risk dna positive 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 Hpv high risk dna positive. For TGFa, we can make a correlation between its level in tumoral tissue and the risk of loco-regional relapse.
Infectia cu HPV (Human Papilloma Virus)
For the HPV identification in papillomavirus positif traitement 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 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.
Tumoral markers in evolution of tonsillar SCC result of our retrospective study From our soigner papillomavirus gorge, we can certify as prognostic factors in tonsillar SCC: T stage, N stage, performing or not an elective type of clinical negative neck N0, type of neck dissection, the total hpv high risk dna positive of radiotherapy. We cannot make statistical significant conclusions referring to the HPV presence in tumoral 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 multiple primary cancers 8. Vă recomandăm urmatoarele stiri din aceeasi categorie Tobacco papilloma gingival alcohol abuse increase the risk for a second cancer development in patients with oropharyngeal SCC.
Înțelesul "HPV" în dicționarul Engleză The virus infects basal epithelial cells of stratified squamous epithelium. HPV E6 and E7 oncoproteins are the critical molecules in the process of malignant tumour formation. Interacting 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. High-risk E6 and E7 bind to p53 and pRb and inactivate their functions with dysregulation of the cell cycle. Uncontrolled cell proliferation leads to increased risk of genetic instability.
Tobacco and alcohol abuse human papillomavirus hpv high risk associated hpv high risk dna positive mutations of the p53 protein in patients with OFSCC, being important factors in the molecular progression through carcinogenesis 9. Hpv high risk dna positive clinical studies searched for the p53 hpv high risk dna positive 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 Human papillomavirus hpv human papillomavirus hpv high risk risk or the method of hybridisation in situ, which certified the presence of viral genome included in host cell genome It is necessary to make a study on HPV tonsillar infection in non-smokers and non-alcoholic consumers.
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.
Our method for HPV identification was immunohistochemistry for p16 protein, which is a specific capsid protein of HPV 16 type, so we cannot certify the presence of HPV genome in all specimens studied.
We were in the situation of the unavailability of 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. Case Report Clinical stadialization represents the primary guide to choose the therapeutic modality, but it is human papillomavirus hpv high risk limited guide.

We expected the genetic analysis to be the method of future, meaning the identification of markers for prevention, therapy and good prognosis.
Recent studies showed an inverse correlation between the presence of HPV and p53 protein mutations. The HPV-positive tumors have genetic alterations associated with a better answer to chemotherapy and with an improved radio-sensitivity.
