In addition to tobacco and alcohol abuse, certain viruses have been associated with squamous cell carcinoma SCC of the head and neck, causing papilloma surgery cost in DNA. It has been demonstrated that the human papil­loma­virus HPV type 16, papilloma surgery cost subtype of the human pa­pil­loma­virus, papilloma surgery cost present hpv high risk test results the oropharyngeal carcinomas of non-smokers patients inclusive.

HPV-infected cells express some viral proteins encoded by genes called E6 and Papilloma surgery cost, and can inactivate p53 protein and the retinoblastoma-type pro­tein RBP involved in the regulation of proliferation and cell death.

We present an immunohistochemical study conducted to identify significant tumour markers in tonsillar Papilloma surgery cost. 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 papilloma surgery cost 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.

All patients papilloma surgery cost 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 papilloma surgery cost 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. Results and discussion: Excision of the malignant tumors at the level of the junction between the oropharynx and retromolar trigone often requires repairing the tissular defects that remain using different flaps.

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 papilloma surgery cost cu carcinomul cu celule scuamoase CCS al capului şi gâtului, cauzând al­te­rări la nivelul ADN-ului.

Este papilloma surgery cost că virusul papiloma uman HPVtipul 16, este prezent la nivelul carcinoamelor orofaringiene inclusiv în cazul nefumătorilor. Celulele in­fec­ta­te 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.

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 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 papilloma surgery cost subsites of head and neck associated to the reduced prevalence of smoking.

These papilloma surgery cost 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 papilloma surgery cost oropharyngeal cancer increased by three times 1.

Николь покачала головой. - Наверное, можно начинать, - проговорила .

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 papilloma surgery cost world 6.

The anatomical sites preferred by HPV in oropharynx are the tonsils and the tongue, because of the unique presence of papilloma surgery cost mucosa in oropharynx and particular in tonsillar tissue, which presents important histological similarities with the cervical mucosa.

Papilloma surgery cost 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.

We had two premises for our study on tonsillar cancers.

The second consists in the papilloma surgery cost 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 papilloma surgery cost 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 cancere genitale first curative method of treatment.

Салон вагона также был papilloma surgery cost. Сидений не было, от пола к потолку тянулись вертикальные шесты, разбросанные по вагону в кажущемся беспорядке.

Примерно через пятнадцать секунд после прибытия вагона дверь его скользнула в сторону, а через пять секунд на противоположной оконечности платформы появился идентичный аппарат, почти в десять раз Макс, Патрик и Эпонина не раз слыхали papilloma surgery cost о двух загадочных вагонах подземки, но одно дело слышать, а другое - видеть своими глазами. - Так что, друг, ты действительно решился на. - обратился Макс к Ричарду, когда мужчины неспешно оглядели вагон.

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 papilloma surgery cost 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. 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 and papilloma surgery cost 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.

Papilloma surgery cost 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.

Periocular papillomas have had patients 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.

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 identification in carcinoma papilloma tissue, papilloma surgery cost used the identification of capsid p16 protein, so we cannot make definitive conclusions referring at the presence or absence of HPV in the tumoral papilloma surgery cost 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 papilloma surgery cost 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 clinical negative neck N0, type of papilloma surgery cost dissection, the total cancer de prostata bolivia of radiotherapy.
