Traducere "cervical cancer cells" în română Implicarea genomului papiloma virusului uman hpv în oncogeneza cancerului cervical Implicarea genomului papiloma virusului uman hpv în oncogeneza cancerului cervical cervical cancer cells - Traducere în română - exemple în engleză Reverso Context Human papillomavirus cancer cells In addition to tobacco and alcohol abuse, certain viruses have human papillomavirus cancer cells associated with squamous cell carcinoma SCC of the head and neck, causing alterations in Hpv 16 and esophageal cancer.

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 presence of immunohistochemical markers and studied local re­cur­rence, lymph node recurrence and risk human papillomavirus cancer cells 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 and in 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 gâtului, cauzând al­te­rări la nivelul ADN-ului.

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

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: a large number of vaginal sex partners, oral and anal sex.

Esophageal cancer hpv Case Report

The recent increasing of OPSCC incidence papillomavirus genital symptomes 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 hpv 16 and esophageal cancer 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 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 human papillomavirus cancer cells We made an immunohistochemical hpv 16 and esophageal cancer study between andaiming to identify any correlations between tumoral human papillomavirus cancer cells and the evolution and prognosis hpv 16 and esophageal cancer tonsillar SCC.

Materials We 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. We had a second group Group II with 27 cases, where the positive diagnose was made on surgical specimens and these patients had surgery 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.

Table 1. Sta je helminti The virus infects basal epithelial cells of stratified squamous epithelium. 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 hpv 16 and esophageal cancer 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.

The correlation coefficient between the two sets of data, corresponding to Group I and Group II, was 0. Thirty-eight cases were well differentiated carcinoma and 14 cases were hpv 16 and esophageal cancer differentiated carcinoma.

We present the results, that we considered immunohistochemically valid and human hpv 16 and esophageal cancer cancer cells 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.

We have had patients who had more than one recurrence in the same time.

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 evolution in tonsillar SCC.

For TGFa, tratamentul paraziților eozinofili can make a correlation between its level in tumoral tissue and the risk of loco-regional human papillomavirus cancer cells. 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.

But we realised a correlation between the presence of HPV and the type of post-therapeutic evolution Figures Figure 1.

Tobacco and alcohol abuse increase the risk for a second cancer development in patients with oropharyngeal SCC. Tobacco and alcohol abuse are associated human papillomavirus cancer cells mutations of the p53 protein in patients with OFSCC, being important factors in the molecular progression through carcinogenesis 9. Hpv 16 and esophageal cancer clinical studies searched for the p53 protein mutations on tinctură antiparazitară specimens from patients with OFSCC.

The patients with surgical positive edges for p53 protein mutations have a higher risk of local relapse P53 protein mutations are involved in the loco-regional failure at OFSCC tonsillar with curative radiotherapy The HPV 16 DNA was identified only in primary tumour cells and in their metastases in similar manner with cervical cancer 3.

The presence of HPV 16 genome was revealed by polymerase chain reaction PCR or the method of hybridisation in hpv 16 and esophageal cancer, which certified the presence of viral genome included in host cell genome Human papillomavirus cancer cells is necessary to make a study on HPV tonsillar infection in non-smokers and non-alcoholic consumers.

Involvement of Human Papillomavirus genome in oncogenesis of cervical cancer Our method for HPV identification was immunohistochemistry for p16 protein, which is a specific capsid protein of HPV 16 type, so we cannot human papillomavirus cancer cells the presence of HPV genome in all specimens studied. We were in the situation of the unavailability of the in situ hybridization kits or polymerase chain reaction for HPV 16 type during the study.

We have to mention the high cost for identifying viral markers. Clinical stadialization represents the primary guide to choose the therapeutic modality, but it is a limited guide. We expected the genetic analysis to be the method of future, meaning the identification of markers for prevention, therapy and good prognosis. Recent studies showed an inverse correlation between the presence of HPV and p53 protein mutations.

The HPV-positive tumors have genetic alterations associated with a better answer human papillomavirus cancer cells chemotherapy and with an improved radio-sensitivity.

The immune response of the patient is better, because of the immune stimulation realised by viral antigens. The younger age with less comorbidities may contribute to a better prognosis Prophylactic vaccination is not efficient in already diagnosed infections and in malignant lesions, so it is necessary to study the efficiency of therapeutic HPV vaccination in the treatment of HPV-associated cancer 1.

We found in lite­rature premises for the therapeutic vaccination in HPV-induced cancers, where this type of vaccine induced a cytolytic immune response in cells which express it 5. It is necessary to study the carriage of HPV in apparently normal tonsillar tissue, to have screening programmes and to select the patients at risk human papillomavirus cancer cells OFSCC Conclusions The prognosis in tonsillar SCC is mediocre, due to local recurrence, nodal relapse, the occurrence of second cancers in upper aerodigestive upper ways 17 and to distance metastases.

From our data, we can certify human papillomavirus cancer cells prognostic factors in tonsillar SCC: T stage, N stage, performing or not an elective type of clinic negative neck N0, type of neck dissection and total dose of radiotherapy.

We cannot draw significant conclusions referring to the HPV presence in tumoral tissue human papilloma virus infection que es tonsillar SCC and regarding the prognosis signification of the HPV presence in the tumoral tissue.

The presence of HPV 16 can be considered a positive prognostic factor for disease-free survival and for healing, but hpv impfung todesfalle use as a predictive marker has not yet been proven. The best vph en el ano hombres sintomas human papillomavirus cancer cells cancer is prevention, especially in malignancies where the main pathogen agent is known, and we are talking here about smoking, alcohol consume and a safe sexual behaviour.
