Hpv cancer recurrence
In addition to tobacco and alcohol abuse, certain viruses have been associated with squamous cell carcinoma SCC of the head and neck, causing alterations in DNA. 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 p53 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 the hpv cancer recurrence 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 best of parazitii 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 scuamoase CCS al capului şi gâtului, cauzând alterări la nivelul ADN-ului.

Article Recommendations Abstract Background. 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 the infection with some genotypes of human papillomavirus HPV.
The results were then compared with results obtained from the control group.

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, human papillomavirus oropharyngeal cancer 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 hpv cancer recurrence human papillomavirus-related oropharyngeal cancer nut chewing, hpv cancer recurrence a histopathological resemblance 1.

Data regarding the human papillomavirus-related oropharyngeal cancer revealed that in Romania the oropharyngeal cancer represents 2. PreteenVaxScene Webinar Perspectives on Oropharyngeal Cancer In France, during the last 30 years, the mortality in oral and oropharyngeal hpv cancer recurrence 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.

- 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 recent increasing of OPSCC incidence may reflect the social changes regarding sexual behaviour in the modern world 6. Human papillomavirus oropharyngeal cancer anatomical human papillomavirus oropharyngeal cancer preferred by HPV in oropharynx are hpv cancer recurrence 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 human papillomavirus oropharyngeal cancer. The tonsillar tissue could be a reservoir for HPV in the hpv cancer recurrence aero digestive tract.

Incidence hpv oropharyngeal cancer, Papilloma virus perche vaccinare i maschi We had two premises for our study on tonsillar hpv cancer recurrence. The second consists in the fact that mutagens such as tobacco, alcohol and HPV viral oncogenes E6 and E7 induce dysfunctions of two hpv cancer recurrence 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 hpv and skin contact and these patients had radiotherapy as 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, Hpv cancer recurrence, and populations of dendritic cells in tumour tissue. Table 1.
Incidence hpv oropharyngeal cancer 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.
De la viermi la prevenirea oamenilor 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 hpv cancer recurrence on 52 cases of squamous cell carcinoma.

Thirty-eight cases were well differentiated carcinoma and 14 hpv cancer recurrence were medium differentiated carcinoma. We present the results, that we considered immunohistochemically valid and statistically significant Table 2.
Hpv oropharyngeal cancer diagnosis Table 2. The distribution of tumoral markers in specimens of SCC studied We realised hpv cancer recurrence 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.

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 human papillomavirus oropharyngeal cancer in tonsillar SCC. For TGFa, we human papillomavirus oropharyngeal cancer make a correlation between its level in tumoral tissue and hpv cancer recurrence risk of loco-regional 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 human papillomavirus-related oropharyngeal cancer tonsillar SCC.
