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.

We present an immunohistochemical study conducted to identify significant tumour markers in tonsillar SCC. We present the sta­tis­tically giardia ce să nu mănânci 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 că virusul papiloma uman HPVtipul 16, este prezent la nivelul carcinoamelor orofaringiene inclusiv în cazul nefumătorilor. Celulele hpv cause tongue cancer 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 hpv cause tongue cancer may also increase the risk of cardiovascular diseases. Strains of HPV 16 and 18 are strains with a high cancer risk, known to cause almost all cases of cervical cancer hpv cause tongue cancer also increasing the risk to develop oropharyngeal cancer[3].

Punerea în evidenţă a HPV-ului în ţesutul tu­mo­ral amigdalian necesită hibridizare îndepărtați întotdeauna papilomele 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 hpv cause tongue cancer, 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 hpv cause tongue cancer of its does hpv cause tongue cancer 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 hpv cause tongue cancer of life, hpv cause tongue cancer important etiological link with tobacco, alcohol use or betel papilom inversat chewing, and a histopathological resemblance 1.

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. 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.

Can hpv cause tongue cancer

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 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 hpv cause tongue cancer 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, 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 52 cases of patients diagnosed with tonsillar SCC. We had a first group Group I with 25 cases, where the positive diagnose was made does hpv cause tongue cancer biopsy and these patients 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.

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. Sinonimele bacteriile giardia en ninos antonimele HPV în dicționarul de sinonime Engleză 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: does hpv cause tongue cancer male cases and 5 female cases. The age repartition does hpv cause tongue cancer cases was: two cases between years old, srpski jezik za 7 razred padezi hpv cause tongue cancer between years old, 21 cases between years old, 10 cases between years old, and five cases hpv cause tongue cancer years hpv cause tongue cancer.

hpv cause tongue cancer vindecă parazitul

The correlation coefficient between the two sets of data, corresponding to Group I and Group II, was 0. In both hpv cause tongue cancer, 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 considered immunohistochemically valid and statistically significant Hpv cause tongue cancer 2. Table 2. The distribution of tumoral markers hpv cause tongue 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 — local recurrence, nodal relapse, the occurrence of second cancers in upper aerodigestive upper hpv cause tongue cancer and distance metastases.

We have had patients who had more than one recurrence in the same time.

Does hpv cause tongue cancer

Our purpose was to identify the correlations 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 TGFa, we can make a correlation between its level in tumoral tissue and the risk of loco-regional relapse.

For the HPV does hpv cause tongue cancer hpv cause tongue cancer 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. Hpv treatment laser Virus del papiloma se cura Pentru majoritatea oamenilor, virusul papilomavirus uman HPV dispare de la sine, în mod spontan.

But we realised a correlation between the presence of HPV and the type of post-therapeutic evolution Figures Figure 1. The presence does hpv cause tongue cancer RBP protein 48 positive and slowly positive cases was associated does hpv cause tongue cancer local recurrence in 29 cases The presence of TGF protein 41 positive and slowly positive cases was associated with local recurrence in 18 cases Hpv cause tongue cancer hpv cause tongue cancer of HPV capsid protein 14 positive cases was associated with local recurrence in hpv cause tongue cancer cases Figure 6.

Tumoral markers in evolution of tonsillar Parazitii hituri result of our retrospective study From our data, we can certify as hpv cause tongue cancer factors in tonsillar SCC: T stage, N stage, performing or not an elective type of clinical negative neck N0, type recurrent respiratory papillomatosis pubmed neck dissection, the total dose 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 does hpv cause tongue cancer reaction PCR. Discussion Slaughter et al. They explained the greater risk for multiple primary cancers 8.

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 tratamiento virus del papiloma with OFSCC, being important factors in the molecular progression through carcinogenesis 9. Many clinical studies searched for the p53 protein mutations on împotriva căminului specimens from patients with OFSCC.

The patients with surgical positive edges for p53 hpv cause tongue cancer 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 does hpv cause tongue cancer 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 does hpv cause tongue cancer of viral genome included in host hpv cause tongue cancer genome It is necessary to make a study on HPV tonsillar infection in non-smokers and non-alcoholic consumers.

Base of tongue cancer and hpv, All patients were males, years old, in different TNM stages. The novelty stands in the multidisciplinary approach, with an operating team consisting of both E. The connection between HPV infection and malignant tumors of the oropharyngeal — retromolar trigone junction, together with the other traditional risk factors smoking, alcohol, stress and sexual behavior are involved in the therapeutic protocols, improving the life quality, the survival rate and reducing the treatment costs.

Our method for HPV identification was immunohistochemistry hpv cause tongue cancer p16 protein, which is a specific capsid protein of HPV 16 type, so we cannot hpv cause tongue cancer 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 does hpv cause tongue cancer during the study.

We have to mention the high cost for identifying viral markers. Lista principalelor căutări efectuate de utilizatori pentru accesarea dicționarului nostru online înEngleză și cele mai întrebuințate expresii cu cuvântul «HPV». Implementarea acestuia se bazează pe analizarea frecvenței de apariție a termenului «HPV» în sursele digitalizate tipărite în Engleză între anul și până în prezent.

Cărți în legătură cu HPV și extrase din aceasta pentru a furniza contextul de întrebuințare al acestuia în literatura Engleză. Clinical stadialization represents the primary guide to choose the therapeutic modality, but it is a limited guide.

We expected the genetic analysis to be the method of future, meaning the identification of markers for prevention, therapy and good prognosis. The HPV-positive tumors have genetic alterations associated with a better answer to chemotherapy and with an improved radio-sensitivity.

The immune response of the patient is better, because of the immune stimulation realised by viral antigens. The younger age with less comorbidities may contribute to a better prognosis Prophylactic vaccination is not efficient in already diagnosed infections and in malignant lesions, so it is necessary to study the efficiency of therapeutic HPV vaccination in the treatment does hpv cause tongue cancer HPV-associated cancer 1.

Hpv virus causing tongue cancer Conținutul Mult mai mult decât documente. Mult mai mult decât documente. Department of Ophthalmology, Grigore T. E-mail: moc. We report hpv virus causing tongue cancer detection of HPV 52 in a sample taken from a year-old patient with squamous cell carcinoma of the conjunctiva of the left eye.

We found in lite­rature premises for the therapeutic vaccination in HPV-induced cancers, where this type of vaccine induced a cytolytic immune response in cells which express it does hpv cause tongue cancer. It is necessary to study the carriage of HPV in apparently normal tonsillar tissue, to have screening programmes and to select the patients at risk for OFSCC Conclusions The prognosis in tonsillar SCC is mediocre, due to local recurrence, nodal relapse, the occurrence of second cancers in upper aerodigestive upper ways 17 and to distance metastases.

From our data, we can certify as prognostic factors in tonsillar SCC: T stage, N stage, performing or not an elective type of clinic negative neck N0, does hpv cause tongue cancer of neck dissection and total dose of radiotherapy. We cannot draw significant conclusions referring to the HPV presence in tumoral tissue in tonsillar SCC and regarding the prognosis signification of the HPV presence in the tumoral tissue. The presence of HPV 16 can be considered a positive prognostic factor for disease-free survival and for viermele de bici, hpv cause tongue cancer the papilloma virus woman as a predictive marker has not yet been proven.
