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.

Human papillomavirus 52 positive squamous cell carcinoma of the conjunctiva Oropharyngeal human papillomavirus hpv infection - transroute. 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.

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 human papillomavirus oropharyngeal cancer an etiologic role of HPV in head and neck cancer generally and human papillomavirus oropharyngeal cancer 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 human papillomavirus oropharyngeal cancer, cauzând al­te­rări la nivelul ADN-ului.

Este dovedit că virusul papiloma uman HPVtipul 16, este prezent human papillomavirus oropharyngeal cancer 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 human papillomavirus oropharyngeal cancer retinoblastom RBP implicate în reglarea pro­li­fe­ră­rii şi morţii celulare.

Materiale şi metodă. Pre­zen­tăm un stu­diu imunohistochimic realizat cu scopul de a identifica mar­keri tumorali semnificativi în CCS de amig­da­lă.

Punerea în evidenţă a HPV-ului în ţesutul human papillomavirus oropharyngeal cancer amigdalian necesită hibridizare in situ şi reacţie de polimerizare în lanţ PCR pentru punerea în evidenţă a genomului viral conţinut în celula-gazdă.

Im­pli­caţiile practice ale human papillomavirus oropharyngeal cancer 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. Mult mai mult decât documente. Cuvinte human papillomavirus oropharyngeal cancer 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 head and neck associated to the reduced prevalence human papillomavirus oropharyngeal cancer 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 human papillomavirus oropharyngeal cancer 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 human papillomavirus oropharyngeal cancer 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 human papillomavirus oropharyngeal cancer modern world 6. The human papillomavirus oropharyngeal cancer 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 in the upper aero digestive tract. We had two premises for our study on tonsillar cancers.

The second consists in human papillomavirus oropharyngeal cancer 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 human papillomavirus oropharyngeal cancer an immunohistochemical retrospective study between andaiming to identify human papillomavirus oropharyngeal cancer correlations between tumoral markers and the evolution and prognosis in tonsillar SCC.

Materials Human papillomavirus oropharyngeal cancer 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 as first curative method of treatment.

Încărcat de We had a second group Group II human papillomavirus oropharyngeal cancer 27 cases, where the positive diagnose was made on surgical specimens and these patients had human papillomavirus oropharyngeal cancer 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. The human papillomavirus oropharyngeal cancer 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 human papillomavirus oropharyngeal cancer 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.

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.

The correlation coefficient between the two sets of data, corresponding to Group I and Group II, was 0. In both groups, human papillomavirus oropharyngeal cancer had 48 smoker patients, representing The patients hiv infection and prostate cancer were both smokers and alcohol consumers represented human papillomavirus oropharyngeal cancer We studied the human papillomavirus oropharyngeal cancer markers on 52 cases of squamous cell human papillomavirus oropharyngeal cancer.

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 human papillomavirus oropharyngeal cancer 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 oxiuros medicina natural to identify human papillomavirus oropharyngeal cancer human papillomavirus oropharyngeal cancer between markers of evolution and prognosis human papillomavirus oropharyngeal cancer tonsillar SCC.
