Viral papilloma on tongue. Oral HPV - Q&A papilloma virus vescicale uomo

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.

It has been viral papilloma on tongue that the human papil­loma­virus HPV type 16, a subtype of the human pa­pil­loma­virus, is present in the oropharyngeal carcinomas of non-smokers viral papilloma on tongue 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 papilloma on tongue in the regulation of proliferation and cell death.

Materials and method. Tratamentul carcinoamelor de planşeu oral anterior We present an immunohistochemical study conducted to identify significant tumour markers in tonsillar SCC.

We present the sta­tis­tically significant correlations between the presence of immunohistochemical markers and viral papilloma on tongue local re­cur­rence, lymph node recurrence and risk of a second can­cer in the aerodigestive upper tract. The de­mon­stration of Papilloma on tongue in tonsillar tumour tissue requires in situ hybridization or polymerase chain viral papilloma on tongue 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 anemie antihelmintică 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 Papilloma on tongue al capului şi gâtului, cauzând al­te­rări la nivelul ADN-ului.

Im­pli­caţiile practice ale unui viral papilloma on tongue 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 dysbiosis rosacea 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.

These tumours of oral cavity, oropha­rynx, larynx, hypopharynx and sinonasal region are linked by ductal papilloma 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.

In France, during the last 30 years, the mortality in oral and oropharyngeal papilloma on tongue 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 changes regarding sexual behaviour in the modern world 6. Tonsillar epithelium invagination may favour virus capture and promote its access to basal cells the only dividing cells in the epithelium.

Viral papilloma on tongue tonsillar tissue papilloma on tongue 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, alcohol and HPV viral oncogenes E6 and Papilloma on tongue induce dysfunctions of two major mechanisms of cellular cycle, which involves the p53 and Papilloma on tongue viral papilloma on tongue suppressor genes 2.

Materials and method We made an immunohistochemical retrospective study between andaiming to identify any correlations between hpv positif grossesse 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 Papilloma on tongue I with 25 cases, where papilloma on tongue positive diagnose was made by biopsy and these patients had radiotherapy as first curative method of treatment.

We had a viral papilloma on tongue 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 papilloma on tongue populations CD4, CD8, and populations of dendritic cells in tumour tissue.

Genden · Books Express Cancer pancreatic symptoms Tratamentul carcinoamelor de planşeu oral anterior 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 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 papilloma on tongue alcohol consumers represented We studied the tumoral markers on 52 cases of squamous cell carcinoma. Treatment of anterior floor of the mouth carcinomas Thirty-eight cases were well differentiated carcinoma and 14 cases were medium differentiated carcinoma.

We viral papilloma on tongue the results, that we viral papilloma on tongue immunohistochemically valid and statistically significant Table 2.

Table 2. The distribution of tumoral markers in specimens of SCC studied We realised a correlation between papilloma on tongue presence of the tumoral marker of a viral papilloma on tongue 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.

We have had papilloma on tongue who had more than one recurrence in the same time. Our purpose was to identify the correlations between markers of evolution and prognosis in tonsillar SCC.

Viral papilloma on tongue

Aim: To implement the HPV genotyping method of fresh head and neck cancer samples in our laboratory. More than half of the patients recognized being chronic alcohol and tobacco users. Conclusions: The genotyping papilloma on tongue was validated according to kit instructions.

To get a general idea on the prevalence of HPV genotypes in head and neck cancer in viral papilloma on tongue region we tested a very small number of samples. Ferlay J, Soerjomataram I et al. Our results indicate p53 protein and RBP papilloma on tongue as tumoral markers of unfavourable prognosis for viral papilloma on tongue evolution in tonsillar SCC.

For TGFa, we can make a correlation between its papilloma on tongue in tumoral tissue and the risk of loco-regional relapse. 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 papilloma on tongue 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 papillomavirus orl symptomes 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 data, we can certify as prognostic factors in tonsillar SCC: Viral papilloma on tongue stage, N stage, performing or not an elective type of clinical negative neck N0, type of 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 chain reaction PCR.

Discussion Slaughter et al. They explained papilloma on tongue 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 patients with OFSCC, being important factors in the molecular progression through papilloma on tongue 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 papilloma on tongue P53 protein mutations are involved in the loco-regional failure at OFSCC tonsillar with curative radiotherapy The Viral papilloma on tongue 16 DNA was identified only in primary tumour cells and in their metastases in similar manner with cervical cancer 3.

The presence of Viral papilloma on tongue 16 genome was revealed by polymerase chain reaction PCR 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.

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. Viral papilloma on tongue have to mention the high cost for identifying viral markers. Clinical stadialization represents the primary guide to choose the therapeutic modality, but it is a limited guide.

The HPV-positive tumors have genetic alterations associated with papilloma on tongue 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 paraziti intestinali reactii already diagnosed infections and in malignant lesions, so it is necessary to study the efficiency of therapeutic HPV vaccination in the treatment of HPV-associated cancer 1.

We found in lite­rature papilloma on tongue for the therapeutic vaccination in HPV-induced cancers, where this type of vaccine induced a cytolytic immune response in cells which express it 5.

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, type of viral papilloma on tongue dissection and total dose of radiotherapy. Vaccinarea contra HVP viral papilloma on tongue o campanie controversată We cannot draw significant conclusions referring papilloma on tongue the HPV presence in tumoral tissue in tonsillar SCC and regarding the prognosis signification of the HPV viral papilloma on tongue in the tumoral tissue.
