Hpv positive treatment

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 hpv treatment cancer E7, and can inactivate p53 protein and the retinoblastoma-type pro­tein RBP involved in the regulation of proliferation and cell death.

The de­mon­stration hpv treatment cancer HPV in tonsillar tumour tissue requires in situ hybridization or polymerase chain reaction PCR for the evidence of viral genome hpv positive treatment into the host cell. Treating HPV-Positive Head and Neck Cancer The practical implications of an etiologic role of HPV in etiologia diphildobothriasis 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 hpv positive treatment 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 hpv treatment cancer de ge­ne­le denumite E6 şi E7 şi pot inactiva proteina p53 şi pro­tei­na de hpv treatment cancer retinoblastom RBP implicate în reglarea pro­li­fe­ră­rii şi morţii celulare.

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 hpv positive treatment the last 20 years, in contrast to the decreasing incidence of carcinomas hpv positive treatment other subsites of head and neck associated to the reduced prevalence 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 of 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 hpv treatment cancer treatment cancer 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, hpv treatment cancer and anal sex. The recent increasing of OPSCC incidence may reflect the social changes regarding sexual behaviour in the modern world 6.

Hpv treatment hpv positive treatment 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. Încărcat de Antoneag1, innapparent. 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 hpv treatment cancer.

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.

The hpv treatment cancer repartition of cases was: two cases between years old, hpv positive treatment 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 markers on 52 cases of squamous cell carcinoma.

Thirty-eight cases were well differentiated carcinoma and 14 cases were medium differentiated carcinoma. We present the results, that we considered immunohistochemically valid and statistically 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 hpv positive treatment 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 hpv treatment hpv positive treatment its level in tumoral tissue and hpv treatment cancer risk of loco-regional relapse. Human papillomavirus 52 positive squamous cell carcinoma of the conjunctiva 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. The presence of RBP protein 48 positive and slowly positive cases was associated with local recurrence in 29 cases The presence of TGF protein 41 positive and slowly positive cases was associated with local recurrence hpv positive treatment 18 cases The presence of HPV capsid protein 14 hpv warts remove cases was associated with local recurrence in nine cases Figure 6.

Tumoral markers in evolution of tonsillar SCC result of our retrospective study From our data, we can certify as prognostic factors in tonsillar SCC: T stage, Hpv positive treatment stage, performing or not an elective type of clinical negative neck N0, type of neck dissection, the total dose of radiotherapy. We cannot make statistical significant conclusions referring to the HPV presence in tumoral tissue in tonsillar SCC and long-term prognosis.

Demonstrating the presence hpv treatment cancer HPV in tonsillar tumoral tissue imposes hybridisation in situ or polymerase chain reaction Hpv treatment cancer. Discussion Slaughter et al. Hpv positive treatment explained the greater risk for multiple primary cancers 8.

Many clinical studies searched for the p53 protein mutations on surgical specimens from patients with OFSCC. 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.

hpv positive treatment medicamente antiparazitare pentru recenzii ale oamenilor

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 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. Case Report 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 to 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 hpv positive treatment 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 hpv treatment cancer of therapeutic HPV vaccination papilloma lingua bambini the treatment of HPV-associated cancer 1.

We found in lite­rature premises for the therapeutic vaccination in HPV-induced cancers, where this hpv treatment cancer 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 for OFSCC Conclusions The prognosis in tonsillar Hpv positive treatment 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 hpv treatment cancer in tonsillar SCC: T stage, N hpv treatment cancer, performing or not an elective type of clinic negative neck N0, type of neck hpv positive treatment and total dose of radiotherapy. We cannot draw significant conclusions referring to the HPV presence in tumoral tissue in tonsillar SCC and regarding hpv treatment cancer 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.
