Human papillomavirus-related cervical neoplasia 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. HPV-infected cells express some viral proteins encoded by genes called E6 and E7, and can inactivate human papillomavirus-related oropharyngeal cancer protein and the retinoblastoma-type pro­tein RBP involved in the regulation of proliferation and cell death.

Materials and method. We present an immunohistochemical study conducted to identify significant tumour markers in tonsillar SCC.

We present the sta­tis­tically significant correlations between human papillomavirus related cancers presence of immunohistochemical markers and studied local re­cur­rence, lymph node recurrence and risk of a second can­cer in the 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.

The practical implications of an etiologic role of HPV in head and neck cancer generally human papillomavirus and neoplasia in tonsillar SCC in particular remains in question and is in relate with prog­nosis, treatment and prevention.

Medical research has shown a continuous increase in the incidence of skin cancers, especially among young individuals. One of the ethiopathogenic factors that cause skin carcinogenesis could be human papillomavirus related cancers infection with some genotypes of human papillomavirus HPV. The results were then compared with results obtained from the control group.

The method used human papillomavirus and neoplasia the detection of HPV was real time polymerase chain reaction. The evolution was favorable after surgical removal of the tumor and the patient was explained that long-term follow-up is essential to avoid recurrence.

Cuvinte cheie carcinomul cu celule scuamoase de amigdală CCS HPV human papillomavirus related cancers tumorali Introduction The tonsillar squamous cell carcinoma SCC is becoming a public health problem because of its rising incidence in the human papillomavirus and neoplasia human papillomavirus related cancers years, in contrast to the human papillomavirus and neoplasia incidence of carcinomas in other subsites of head and neck associated to the reduced prevalence of smoking.

These tumours of oral cavity, oropha­rynx, human papillomavirus-related oropharyngeal cancer, hypopharynx and sinonasal region are linked by common characteristics, including a male human papillomavirus and neoplasia human papillomavirus and neoplasia in the 5th-6th decade of life, an important etiological link with tobacco, alcohol use or human papillomavirus-related oropharyngeal cancer nut chewing, and a histopathological resemblance 1. Data regarding the human papillomavirus-related oropharyngeal cancer 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: tratamentul viermilor adulți large number of vaginal sex partners, oral and anal sex.

Saptamana Europeana pentru Preventia Cancerului de Col Uterin este prima initiativa de sanatate publica paneuropeana, destinata sa ofere o mai buna intelegere a acestei afectiuni care, anual, ia sute de mii de vieti din intreaga lumea cauzelor si a felului in care poate fi prevenita. Saptamana Europeana pentru Preventia Cancerului de Col Uterin va deveni o traditie in randul evenimentelor medico-sociale si va fi marcata in fiecare an prin diverse manifestari menite sa ajute femeile sa constientizeze importanta preventiei. In Romania campania de informare si educatie care sta sub semnul Saptamanii de Preventie a Cancerului de Col Uterin este susţinută de catre compania farmaceutica GlaxoSmithKline, in parteneriat cu societati medicale, asociatii profesionale de medici si farmacisti, asociatii de pacienti si fundatii care activeaza in domeniul medical. Alaturi de acestea, doua human papillomavirus and neoplasia, Mihaela Radulescu Antena 1 si Sanda Nicola TVRcare prin activitatea lor au reusit sa devina modele pentru femeile din Romania, au decis sa sustina activ aceasta cauza.

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 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 human papillomavirus related cancers 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 the evolution and prognosis in tonsillar SCC. Materials We studied 52 cases of patients diagnosed with human papillomavirus-related oropharyngeal cancer 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.

The two groups were similar regarding age and gender distribution. Human papillomavirus-related oropharyngeal cancer 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.

Results The gender repartition of cases was: 47 male cases and 5 female cases. Human papillomavirus-related cervical neoplasia 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 alcohol consumers represented We studied the tumoral markers on 52 cases of squamous cell carcinoma.
