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 human papillomavirus and related cancers 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 and in tonsillar SCC in particular remains in question and is in relate with prog­nosis, treatment and prevention.

Human papillomavirus-related oropharyngeal cancer afară de consumul de tutun şi abuzul human papillomavirus-related oropharyngeal cancer al­cool, anumite virusuri au fost asociate cu carcinomul cu celule human papillomavirus and related cancers CCS al capului şi gâtului, cauzând al­te­rări la nivelul Human papillomavirus and related cancers. Este dovedit că virusul papiloma uman HPVtipul 16, este prezent la nivelul carcinoamelor orofaringiene inclusiv în cazul nefumătorilor.

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.

Implicarea genomului papiloma virusului uman hpv în oncogeneza cancerului cervical Human papillomavirus-related cervical neoplasia 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 method used for 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.

Human papillomavirus 52 positive squamous cell carcinoma of the conjunctiva

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 last human papillomavirus related cancers 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, human papillomavirus-related oropharyngeal cancer, 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 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 human papillomavirus and related cancers 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.

The recent increasing of OPSCC incidence may reflect the social changes regarding sexual behaviour in the modern world 6.

Hpv cancer prevalence.

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 reteta detoxifiere ficat 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.

Case Report

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. Human papillomavirus-related cervical neoplasia The age human papillomavirus and related cancers 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 human papillomavirus and related cancers 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.
