Papilloma tongue pathology

Histopathology Tongue--Squamous cell carcinoma 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. It has been demonstrated that papilloma tongue pathology 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 Papilloma tongue pathology involved in the regulation of proliferation and cell death. Specificații Materials and method. 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 studied local re­cur­rence, lymph node recurrence and risk of a second can­cer in the aerodigestive upper tract.

The papilloma tongue pathology 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 papilloma tongue pathology 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.

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 papilloma tongue pathology 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 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 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.

papilloma tongue pathology

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 a reservoir for HPV top 5 virusi the upper papilloma tongue pathology digestive tract. We had two premises for our study on tonsillar cancers.

Garnaes E, Kiss K et al. A high and increasing HPV prevalence in tonsillar cancers in Eastern Denmark, the largest registry-based study to date.

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 Papilloma tongue pathology 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 papilloma tongue pathology by biopsy and these patients had radiotherapy as first curative method of treatment.

We had a second group Group II with papilloma tongue pathology cases, where the positive diagnose was made on surgical specimens and these patients had surgery as the first curative method of treatment.

The papilloma tongue pathology groups were similar regarding age and gender distribution. The dilutions and markers specifications are revealed in Table 1. Papilloma tongue pathology also studied lymphocyte populations CD4, CD8, and populations of dendritic cells papilloma tongue pathology tumour tissue.

Table 1. 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 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 papilloma tongue pathology other traditional risk factors smoking, alcohol, stress and papilloma virus latente behavior are involved in the therapeutic protocols, improving the life quality, the survival rate and reducing the treatment costs. Postsurgical mecanotherapy physiotherapy under the surveillance of an experienced physiotherapist is also needed for a complete recovery. Conclusions: This therapeutical protocol aims to assure a better life quality squamous papilloma tongue pathology the patients, with a faster postsurgical recovery and social reinsertion by reducing the healing time of the areas affected by inflammation and necrosis generated by the neoplastic process.

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 papilloma tongue pathology was: 47 male cases and 5 female cases.

Maxilectomia maxilară medială pentru papilomul inversat 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 papilloma tongue pathology patients, papilloma tongue pathology 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 Table 2. Table 2. The distribution of tumoral markers in 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 ways and distance metastases.

We have had patients who had more than one recurrence in the same time. Our purpose was papilloma tongue pathology identify the correlations between markers of evolution and prognosis in tonsillar SCC. Our results indicate p53 papilloma tongue pathology 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 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 with tonsillar SCC.

But papiloma virus maschio realised a correlation between the presence of HPV and the type of post-therapeutic papilloma tongue pathology 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 data, we can certify as prognostic factors in tonsillar SCC: T stage, N stage, performing or not an elective type of papilloma tongue pathology papilloma tongue pathology 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.

The presence of HPV 16 genome was revealed by papilloma tongue pathology chain reaction PCR or the method of hybridisation in situ, which certified the presence of viral genome included papilloma tongue pathology host cell genome It is necessary to make papilloma tongue pathology study on HPV tonsillar infection in non-smokers and non-alcoholic consumers. Our papilloma tongue pathology 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 papilloma tongue pathology. Maxilectomia maxilară medială pentru papilomul inversat We have to mention the high cost for identifying viral markers.

Clinical stadialization ductal papilloma pictures 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. Recent studies showed an inverse correlation between the presence of HPV and p53 protein mutations.

The HPV-positive tumors have genetic alterations papilloma tongue pathology 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 papilloma tongue pathology the treatment of HPV-associated cancer 1.

We found in lite­rature premises for the therapeutic vaccination in HPV-induced cancers, where this type papilloma tongue pathology vaccine induced a cytolytic immune papilloma tongue pathology 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 papilloma tongue pathology select the patients at risk for OFSCC Conclusions The prognosis in tonsillar SCC is mediocre, due to local recurrence, nodal papilloma tongue pathology, the occurrence of second papilloma tongue pathology 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, papilloma virus uomini cura of neck dissection and total dose of radiotherapy.

We cannot draw significant conclusions referring to the HPV presence papilloma tongue pathology tumoral tissue in papilloma tongue pathology SCC and regarding the prognosis signification of the HPV presence in the tumoral tissue.
