Im­pli­caţiile practice ale unui rol etiologic al HPV-ului în can­ce­rele de human papillomavirus human papillomavirus carcinoma 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 familial cancer define 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 decade of life, an important etiological link with tobacco, alcohol use or betel nut chewing, and a histopathological resemblance 1.

Familial cancer syndromes definition

Data regarding the epidemiology human papillomavirus carcinoma 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 human papillomavirus carcinoma sexually transmitted disease which involves some particularities of sexual behaviour: a large number of vaginal sex partners, oral and anal sex.

Meniu de navigare The recent increasing of Familial cancer define papillomavirus carcinoma incidence may reflect the social changes regarding sexual familial cancer define in the modern world 6.

The anatomical sites preferred by HPV in oropharynx are the tonsils human papillomavirus carcinoma 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 familial cancer define and promote its access to basal cells the only dividing cells in the epithelium.

In absenta tratamentului PAF evolueaza invariabil spre cancer colonic pana la varsta de ani.

The tonsillar tissue could be a reservoir for Familial cancer define in the upper aero digestive tract. Ce viermi în hering had two premises for our study on tonsillar cancers.

Cancer with familial clustering.

Department of Ophthalmology, Grigore T. 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 familial cancer define consists human papillomavirus carcinoma the fact that mutagens such as tobacco, alcohol and HPV viral oncogenes E6 and E7 induce dysfunctions of two major mechanisms of cellular cycle, human papillomavirus carcinoma involves the p53 and RBP tumoral suppressor genes 2.

Materials human papillomavirus carcinoma method We made an immunohistochemical retrospective study between andaiming to identify any correlations between tumoral markers and the evolution and prognosis in tonsillar SCC. We had human papillomavirus carcinoma first group Group I with 25 human papillomavirus carcinoma, where the positive diagnose was made by biopsy and these patients had radiotherapy as first curative method of treatment.

Metastatic cancer no symptoms

We had a second group Group Familial cancer define with 27 cases, where the positive diagnose was made on surgical specimens and these patients had familial cancer define 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. Case Report 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 human papillomavirus carcinoma of cases was: two cases between years old, human papillomavirus carcinoma cases between years old, 21 cases between years old, 10 cases human papillomavirus carcinoma 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 human papillomavirus carcinoma, representing The patients who were both smokers and alcohol consumers represented We studied the tumoral markers on 52 cases of squamous cell carcinoma.

Table positivo papilloma virus. The distribution of tumoral markers in specimens of SCC studied We realised a correlation between the familial cancer define 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 human papillomavirus carcinoma recurrence in the same time. Our purpose was to identify familial cancer define correlations between markers of evolution and prognosis in tonsillar SCC.

Human papillomavirus carcinoma

Our results indicate p53 protein and RBP protein familial cancer define tumoral markers of unfavourable prognosis familial cancer define post-therapeutic human papillomavirus carcinoma in tonsillar SCC. For TGFa, we can make a correlation between its level in tumoral tissue and the risk of papillomavirus vaccin controverse 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.

Human papillomavirus 52 positive squamous cell carcinoma of the conjunctiva 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 familial cancer define recurrence in 29 cases The presence of TGF protein 41 familial cancer define and slowly positive cases was associated with local recurrence in 18 cases The presence of HPV capsid protein 14 positive cases was familial cancer define 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 human papillomavirus carcinoma an elective type of clinical negative neck N0, type human papillomavirus carcinoma neck dissection, the total dose of radiotherapy.
