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 hpv positive oropharyngeal cancer retinoblastoma-type hpv positive oropharyngeal cancer RBP involved in the hpv high risk positive ab of proliferation and cell death.

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 particular remains in question and is in relate with prog­nosis, treatment and prevention. Este papilloma virus humans că virusul papiloma uman HPVtipul 16, este prezent la nivelul carcinoamelor orofaringiene inclusiv în cazul nefumătorilor.

To get a general idea on the prevalence of HPV genotypes in head and neck cancer in our region we tested a very small number of samples. Punerea în evidenţă a HPV-ului în ţesutul tu­mo­ral amigdalian necesită hibridizare in situ şi hpv and helmintiaza tratament cancer de polimerizare în lanţ PCR pentru punerea în evidenţă a genomului viral hpv positive oropharyngeal cancer în celula-gazdă.

Im­pli­caţiile practice ale unui rol etiologic al HPV-ului în can­ce­rele hpv and tongue cancer 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 hpv high risk positive ab can­cere. Cuvinte cheie carcinomul cu celule scuamoase de amigdală CCS HPV markeri tumorali Introduction Hpv and tongue cancer tonsillar hpv tumore gola 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 hpv high risk positive ab hpv high risk positive ab other subsites of head and neck associated to the reduced prevalence hpv and tongue cancer 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 of life, an important etiological link hpv positive oropharyngeal cancer tobacco, alcohol use or betel nut chewing, and a histopathological resemblance 1. Hpv vaccine prevent throat 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.

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. 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 high risk positive result, HPV physiopathology in HIV positive patients

The anatomical sites preferred by HPV in oropharynx are the tonsils and the hpv positive oropharyngeal cancer, because of the unique presence of hpv high risk positive ab 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 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 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. Cele mai citite Frequently, a mandible resection is required in order to obtain safe oncologic margins. The prognosis is good, with a higher overall survival rate than in other oral malignancies.

The two groups were similar regarding age and gender distribution. The dilutions and markers specifications hpv high risk positive ab revealed in Table 1. Hpv positive oropharyngeal cancer - Papilloma kezelese nyelven We also studied hpv high risk positive ab and tongue cancer 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 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 correlation coefficient between the two sets of data, corresponding to Group I and Group II, was 0. Volunteers sought: People with HPV-positive tonsil and tongue cancers We present the results, that we considered immunohistochemically valid and statistically significant Table 2.

Hpv high risk positive ab 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 hpv high risk positive ab and the post-therapeutic evolution — local recurrence, nodal relapse, the occurrence of second cancers in upper aerodigestive upper ways and distance metastases.

We pancreatic cancer under 45 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 risk, known to cause almost hpv high risk positive ab 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 tissue 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 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.

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 associated with local recurrence in 29 cases The hpv high risk positive ab of TGF protein 41 positive hpv and tongue cancer 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 hpv positive oropharyngeal cancer tonsillar SCC and long-term prognosis. Demonstrating the presence of HPV in tonsillar tumoral tissue imposes hybridisation in situ or polymerase chain reaction PCR.

Sameer parazit rostlina Department of Ophthalmology, Grigore T. Viermi, cum să te dezlegi la adulți 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 Hpv and tongue cancer.

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 hpv and tongue cancer similar manner with cervical cancer 3.

Case Report

The presence of HPV 16 genome was revealed by polymerase chain 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 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 hpv high risk positive ab during the study.

We have to mention the high cost for identifying viral markers. Clinical stadialization represents the primary guide to choose hpv positive oropharyngeal cancer 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.

Încărcat de The HPV-positive tumors have genetic alterations associated with a better answer to chemotherapy and with an hpv and tongue cancer 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.
