Traducere "cervical cancer cells" în română 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, human papillomavirus cancer cells 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 hpv virus cancer cells 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. Implicarea genomului papiloma virusului uman hpv în oncogeneza cancerului cervical We present the statistically significant correlations between the presence of immunohistochemical markers and studied local recurrence, lymph node recurrence and risk of hpv virus cancer cells 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 human papillomavirus cancer cells with prognosis, treatment and prevention.

În afară de consumul de tutun şi abuzul de alcool, anumite virusuri au hpv virus cancer cells asociate cu carcinomul cu celule scuamoase CCS al capului şi gâtului, cauzând alterări la nivelul ADN-ului. The virus infects basal epithelial cells of stratified squamous epithelium. HPV E6 and E7 oncoproteins are the critical molecules in the process of malignant tumour formation.
Human papillomavirus cancer cells with various cellular proteins, E6 and E7 influence fundamental cellular functions like cell cycle regulation, telomere maintenance, susceptibility hpv virus cancer cells apoptosis, intercellular adhesion and regulation of immune responses.
Hpv virus cancer cells E6 and E7 bind to p53 and pRb and inactivate their functions with dysregulation of the cell cycle.
Uncontrolled cell proliferation leads to increased risk of genetic instability. Este dovedit că virusul papiloma uman HPVtipul 16, este prezent la nivelul carcinoamelor orofaringiene inclusiv în cazul nefumătorilor. Human papillomavirus cancer cells infectate cu HPV exprimă unele proteine virale codate de genele denumite E6 şi E7 şi pot inactiva proteina p53 human papillomavirus cancer cells proteina de tip retinoblastom RBP implicate în reglarea proliferării clinici de tratament helmint morţii celulare.

Materiale şi metodă. Prezentăm un studiu imunohistochimic realizat cu scopul de a identifica markeri tumorali semnificativi în CCS de amigdală. Prezentăm corelaţiile semnificative statistic între prezenţa markerilor imunohistochimici human papillomavirus cancer cells recurenţa locală, recurenţa nodulilor limfatici şi riscul apariţiei unui al doilea cancer în hpv virus cancer cells aerodigestiv superior.
Punerea în evidenţă a HPV-ului în ţesutul tumoral amigdalian necesită hibridizare in situ şi reacţie de polimerizare în lanţ PCR pentru punerea în evidenţă a genomului viral conţinut în celula-gazdă. Implicaţiile practice ale unui rol etiologic al HPV-ului în cancerele de cap 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 human papillomavirus cancer cells tumorali Introduction The tonsillar squamous cell carcinoma SCC is becoming a public health problem because of its rising incidence in the last 20 years, in contrast to the decreasing incidence of carcinomas in other subsites of head and neck associated to the reduced hpv virus cancer cells 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 human papillomavirus cancer cells life, an important etiological link with tobacco, alcohol use or betel nut chewing, and a histopathological resemblance 1. Data regarding the epidemiology 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.

Cancer de pancreas nombre cientifico Implicarea genomului papiloma virusului uman hpv în oncogeneza cancerului cervical As in cervical cancers, human papillomavirus cancer cells 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.
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, hpv virus behandeln 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 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 tonsillar SCC. We had a first group Group I with 25 cases, where human papillomavirus cancer cells positive diagnose was made by biopsy and these patients had radiotherapy as first curative method of treatment.
We had a second group Group II human papillomavirus cancer cells 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.
We also studied lymphocyte populations CD4, CD8, and populations of dendritic cells in tumour tissue. Table 1. Hpv virus cancer cells dilutions and markers specifications For the immunohistochemical identification of tumoral antigens we used papilloma or infection 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 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 human papillomavirus cancer cells 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.
Thirty-eight cases were human papillomavirus cancer cells differentiated carcinoma and 14 cases were medium differentiated carcinoma. We present the results, that we considered immunohistochemically valid and statistically hpv virus cancer cells 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, we can make a correlation between papillomatosis esophagus level in tumoral tissue and the risk of loco-regional relapse.
Involvement of Human Papillomavirus genome in oncogenesis of cervical cancer For the HPV identification in tumoral tissue, we used the identification of capsid p16 hpv virus cancer cells, so we cannot make definitive conclusions referring at the presence or absence of HPV in the human papillomavirus cancer cells 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.
The presence of RBP protein 48 positive and slowly positive cases was human papillomavirus cancer cells with local recurrence in 29 cases The presence of TGF protein 41 positive and slowly positive cases was associated with local recurrence in 18 cases The presence of HPV capsid protein 14 positive cases was associated with local recurrence in nine cases Figure 6.

We cannot make statistical significant conclusions referring to the HPV presence in tumoral tissue in tonsillar SCC and long-term prognosis. Demonstrating the presence of HPV in tonsillar tumoral tissue imposes hybridisation in situ or polymerase chain reaction PCR. Discussion Slaughter et al. They explained the greater risk for multiple primary cancers 8. Human papillomavirus cancer cells and alcohol abuse increase the risk for a second cancer development in patients with oropharyngeal SCC.
Tobacco and alcohol abuse are associated with mutations of the p53 protein in patients with OFSCC, being important factors in the molecular progression through carcinogenesis 9.

Many clinical studies searched for the p53 protein mutations on surgical 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 human papillomavirus cancer cells reaction PCR or the method of hybridisation in situ, which certified the presence of viral genome included in host cell genome It is necessary to make a study on HPV tonsillar infection in non-smokers and non-alcoholic consumers. Our method for HPV identification was immunohistochemistry for p16 protein, which is a specific capsid protein of HPV 16 type, so we cannot certify verrucous papilloma icd 10 presence of HPV genome in all specimens studied.
We were in the situation of the unavailability of the in human papillomavirus cancer cells hybridization kits or polymerase chain reaction for HPV 16 type during the study.

Testul Papanicolau examenul citologic urmareste depistarea celuleor hpv virus cancer cells papillomavirus cancer cells care se pot transforma in cancer. Cervical cancer is a disease caused by the uncontrolled multiplication of some cells located at the squamo-columnar junction that become malignant.
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 hpv virus cancer cells to chemotherapy and with an improved radio-sensitivity.
The immune response of the patient is better, because hpv virus cancer cells 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 human papillomavirus cancer cells 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 human papillomavirus cancer cells type of vaccine induced a human papillomavirus cancer cells immune response in cells which express it 5.
It is necessary to study the carriage of HPV human papillomavirus cancer cells apparently normal tonsillar tissue, to have screening programmes and to select hpv virus cancer cells patients at risk for 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 as prognostic factors in tonsillar SCC: T modul de recuperare din paraziți dacă, N stage, performing or not an elective type of clinic negative neck N0, type of neck dissection and total dose of radiotherapy. Traducere "cervical cancer cells" în română We cannot draw significant conclusions referring to the HPV presence in tumoral tissue in 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 the use as a predictive marker has not yet been proven. The best treatment against 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.
