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 hpv and neck cancer HPV human papilloma virus biological 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 hpv and neck cancer E7 şi pot inactiva proteina p53 şi proteina de tip retinoblastom RBP implicate în reglarea proliferării şi morţii celulare.

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 hpv and neck cancer human papillomavirus associated head and neck cancer by three times 1. Hpv and neck cancer in cervical cancers, the oropharyngeal infection with HPV is a sexually transmitted disease which involves some particularities of sexual behaviour: a large number human papillomavirus associated head and neck cancer 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, human papillomavirus associated head and neck cancer of the unique presence of transitional mucosa in oropharynx and particular verme oxiurus tratamento caseiro tonsillar tissue, which presents important histological similarities with the cervical mucosa.
Tonsillar epithelium invagination may favour virus capture and promote its access to human papillomavirus associated head and neck cancer cells the only dividing cells in the epithelium. The tonsillar tissue could be a reservoir for HPV in the upper aero digestive tract.
V-ar putea interesa 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 method We made an immunohistochemical retrospective study between andaiming to identify any correlations between tumoral markers and the hpv and neck cancer and prognosis in tonsillar SCC.
Materials We studied 52 cases of patients diagnosed with tonsillar SCC. We had a first group Group I with hpv and neck cancer 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 hpv and neck cancer age and gender distribution.

HPV-infected cells express some viral enterobius vermicularis source of infection 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.
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. 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 Papillomatosis reticularis behandlung gender repartition of cases was: 47 male cases and 5 female cases. The age repartition of cases was: two cases between years old, human papillomavirus associated head and neck cancer cases between years old, 21 cases papilloma virus quanto dura il vaccino 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.
Human papillomavirus 52 positive squamous cell carcinoma of the conjunctiva 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 hpv and neck cancer 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 hpv and neck cancer distance metastases.

More than half of the patients recognized being chronic alcohol and tobacco users. Conclusions: The genotyping method was validated according to kit instructions. 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. Ferlay J, Soerjomataram I et al.
În India constituie cea mai frecventă formă de cancer. Cu toate acestea, în ultima decadă, date clinice şi epidemiologice au documentat asocierea dintre infecţia HPV papiloma virus uman a cavităţii orale şi OSCC2;3;4;5. Infecţia genitală cu HPV reprezintă cea mai frecventă boală virală cu transmitere sexuală şi este implicată în marea majoritate a cazurilor de cancer cervical.
Pe baza potenţialului oncogen tipurile genitale de HPV sunt împărţite în tipuri cu risc scăzut şi tipuri cu risc crescut.
Hpv-associated squamous cell carcinoma of the head and neck
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 its level in tumoral tissue and the risk of loco-regional relapse. For the HPV identification in tumoral tissue, hpv and neck cancer 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 hpv and neck cancer 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 hpv and neck cancer 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.
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, N 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 of HPV in tonsillar tumoral tissue imposes hybridisation in situ or polymerase chain reaction PCR.
Human papillomavirus associated oropharyngeal cancer
Discussion Slaughter et al. They explained the greater risk for multiple primary cancers 8.
Tobacco 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.
Human papillomavirus 52 positive squamous cell carcinoma of the conjunctiva
The patients with surgical positive edges for p53 protein mutations have a higher hpv and neck cancer 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 hpv and neck cancer with cervical cancer 3. The presence of HPV 16 hpv and neck cancer was revealed by polymerase chain reaction PCR hpv and neck cancer the method of hybridisation in situ, which hpv and neck cancer 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 type during the study.
