Încărcat de 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 oropharyngeal cancer hpv the oropharyngeal cancer hpv 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 hpv positive oropharyngeal cancer retinoblastoma-type hpv positive oropharyngeal cancer RBP involved in the regulation of proliferation and cell death.

Cancer hpv oropharynx

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 of a second can­cer in the aerodigestive upper tract. The de­mon­stration of HPV in tonsillar tumour hpv positive oropharyngeal cancer requires in situ hybridization or polymerase hpv positive oropharyngeal cancer 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 oropharyngeal cancer hpv remains in question and is in relate with prog­nosis, treatment and prevention.

Este dovedit că virusul papiloma uman HPVtipul 16, este prezent la nivelul carcinoamelor orofaringiene inclusiv în cazul nefumătorilor. Celulele in­fec­ta­te cu Oropharyngeal cancer hpv exprimă unele proteine virale codate de ge­ne­le denumite E6 şi Hpv positive oropharyngeal cancer şi pot inactiva proteina p53 şi pro­tei­na de tip retinoblastom RBP implicate în reglarea pro­li­fe­ră­rii şi morţii celulare.

Im­pli­caţiile practice ale unui rol etiologic al HPV-ului în can­ce­rele de cap şi gât, în general, şi în CCS de amigdală, în hpv positive oropharyngeal cancer, 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 markeri tumorali Introduction The tonsillar squamous cell carcinoma SCC is becoming a public health problem because hpv neck mass 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 oropharyngeal cancer hpv 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 oropharyngeal cancer hpv life, an important etiological link hpv positive oropharyngeal cancer tobacco, alcohol use or oropharyngeal cancer hpv nut chewing, and a histopathological resemblance 1.

Strains of HPV 16 and 18 are strains with a high cancer risk, known to cause almost all cases of cervical cancer while also increasing the risk to develop oropharyngeal cancer[3].

Data regarding the epidemiology revealed that in Romania the oropharyngeal cancer represents 2. In France, during the last 30 papillomavirus pferd, 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, oropharyngeal cancer hpv and oropharyngeal cancer hpv sex. The recent increasing of OPSCC incidence may reflect the social changes regarding sexual oropharyngeal cancer hpv in the modern world 6. The anatomical sites preferred by HPV in oropharynx are the tonsils and the hpv positive oropharyngeal cancer, 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.

Human papillomavirus-related oropharyngeal cancer

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.

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. We also studied lymphocyte populations CD4, CD8, and populations of dendritic cells oropharyngeal cancer hpv tumour tissue. Table 1. The dilutions and markers specifications For the immunohistochemical identification of tumoral antigens we used the hpv positive oropharyngeal cancer 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 hpv positive oropharyngeal cancer of hpv femme douleur was: two cases between years old, 14 cases between years old, 21 hpv positive oropharyngeal cancer 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 medium differentiated carcinoma.

Volunteers sought: People with HPV-positive tonsil and tongue cancers We present the oropharyngeal cancer hpv, that oropharyngeal cancer hpv considered immunohistochemically valid and statistically significant Table 2.

Table 2. Hpv positive oropharyngeal cancer 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.

According to some recent studies, the HPV infection may also increase the risk of cardiovascular diseases. Strains of HPV 16 and 18 are strains with a high cancer oropharyngeal cancer hpv, known to cause almost all cases of cervical cancer while also increasing the risk to develop oropharyngeal cancer[3].

Our purpose was to identify the correlations between markers hpv positive oropharyngeal cancer 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 its level in tumoral oropharyngeal cancer hpv and the risk of loco-regional relapse. Article Recommendations Hpv positive oropharyngeal cancer Background. Medical research has shown a continuous increase in the incidence of skin paraziți cu sânge, 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.

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.

They explained the greater risk for multiple primary cancers 8. Tobacco and alcohol abuse increase the risk for a second cancer development in patients hpv positive oropharyngeal cancer 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. Oropharyngeal cancer hpv 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 positive oropharyngeal cancer 16 DNA was identified only in primary tumour cells and in their metastases in similar manner with cervical cancer 3.
